Cardiogenic shock with ST-segment elevation acute coronary syndrome (ReNa-Shock ST).

Cardiogenic shock (CS) in the setting of an ST-segment elevation myocardial infarction (STEMI) is a severe complication and constitutes one of the principal causes of death associated with this condition. The aim of this study was to describe the clinical characteristics, treatment strategies and hospital outcome of CS associated with STEMI in Argentina. The Argentine Registry of Cardiogenic Shock (ReNA-Shock) was a prospective and multicenter registry of consecutive patients with CS hospitalized in 64 centers in Argentina between July 2013 and May 2015. Only those with ST-segment elevation myocardial infarction (STEMI) were selected for this analysis. Of the 165 patients included in the ReNa-Shock registry, 124 presented STEMI. Median age was 64 years (IQR 25-75: 56.5-75) and 67% were men; median time from symptom onset to admission was 240 minutes (IQR 25-75: 132-720). 63% of the cases presented CS at admission. Eighty-seven percent underwent reperfusion therapy: 80% primary percutaneous intervention with a median door-to-balloon time of 110 minutes (IQR 25-75: 62-184). Inotropic agents were used in 96%; 79% required mechanical ventilation; a Swan Ganz catheter was inserted in 47% and 35% required intra-aortic balloon pumping. Most patients (59%) presented multivessel disease (MV). Hospital mortality was 54%. Multivariate analysis identified that time from symptom onset to admission (> 240 min) was the only independent predictor of mortality (OR: 3.04; CI 95%: 1.18-7.9). Despite using treatment strategies currently available, morbidity and mortality of STEMI complicated with CS remains high.

Heart Failure at Admission Complicating ST-Elevation Myocardial Infarction in a Middle-Income Country. Experience of the ARGEN-IAM-ST Registry.

Despite advances in the management of ST-elevation myocardial infarction (STEMI), when associated with heart failure (HF) its prognosis remains ominous. This study assessed the differences in admission and mortality of HF complicating STEMI at admission (HFad) in a middle-income country. Data from the National Registry of STEMI of Argentina (ARGEN-IAM-ST) from January 1, 2016, to September 30, 2020, were analyzed. HFad was defined by the identification of Killip/Kimball ≥2 at admission. About 3174 patients were analyzed (22.3% had HFad). Patients with HFad were older, more often women, hypertensive, and diabetic. Received less reperfusion (87.6% vs 92.6%, P < 0.001) and had increased in-hospital mortality (28.4% vs 3.0%, P < 0.001). In multivariate analysis HFad was an independent predictor of death (OR: 4.88 [95%CI: 3.33-7.18], P < 0.001) and reperfusion adjusted to HFad was associated with lower mortality (OR: 0.57 [95%CI: 0.34-0.95], P = 0.03). HFad in STEMI is associated with a worse clinical profile, receives fewer reperfusion strategies, and carries a higher risk of in-hospital mortality while reperfusion reduces mortality.

Prognostic Value of Insulin Resistance Assessed by HOMA-IR in Non-Diabetic Patients with Decompensated Heart Failure.

The predictive value of insulin resistance in patients hospitalized with heart failure is unknown. To evaluate prognostic value of insulin resistance (defined by a HOMA IR ≥ 2.5) for the combined event of death and readmission at 90 and 365 days post discharge and to determine if there are differences according to ejection fraction. Prospective study of 156 p hospitalized for acute heart failure without diabetes. A total of 83 years, 48% female, EF ≤ 45% 48%. Of 28% presented HOMA ≥2.5. HOMA IR ≥2.5 was associated with combined event (OR 2.4; 95% CI 1.9-5.1; P: 0.02) at 90 days. A multivariate analysis demonstrated its independent predictive value (OR 2.5, 95% CI 1.1-5.8; P: 0.03). At 1 year follow-up HOMA IR did not predict events. The predictive value of HOMA-IR was not associated with ventricular function. HOMA IR index was a predictor of a combined event at 90 days in our population. It is a simple determination that could contribute to identify higher risk patients during this vulnerable post-discharge phase. These data must be validated in larger studies.

Clinical characteristics and evolution of patients with cardiogenic shock in Argentina in the context of an acute myocardial infarction with ST segment elevation. Data from the nationwide ARGEN-IAM-ST Registry.

Cardiogenic Shock is one of the main causes of death in ST segment Elevation Myocardial Infarction. To know the clinical characteristics, in-hospital evolution and mortality of patients with Cardiogenic Shock. Patients enrolled in the ARGEN-IAM-ST Registry were analyzed. Predictors of Cardiogenic Shock and death during hospital stay were established. A total of 6122 patients were admitted between 2015 and 2022. Cardiogenic Shock was present in 10.75% of cases. Patients with CS were older (64.5 vs 60 years), more females (41% vs 36%), with more antecedents of infarction and a higher prevalence of anterior location of infarction and multivessel disease. They were also less revascularized (88.5% vs 91.5%) and had a higher incidence of failed angioplasty (15.7% vs 2.7%). They also evidenced a higher occurrence of mechanical complications (6.8% vs 0.4%), ischemic recurrence (7.4% vs 3.4%) and cardiac arrest on admission (44.8% vs 2.6%). All the differences described showed statistical significance with P < 0.05. Overall mortality was 58% in contrast to 2.77% in patients without Cardiogenic Shock (P < 0.001). Only age, DBT, and early cardiac arrest were independent predictors of shock on admission whereas age, female gender, cardiac arrest on admission and failed angioplasty were independent predictors of death. One out of 10 patients with ST Elevation Myocardial Infarction presented cardiogenic shock. Its clinical characteristics were similar to those described more than 20 years ago. Despite a high use of reperfusion strategy cardiogenic shock continues to have a very high mortality Argentina.

[Incidence and clinical characteristics of patients with ST-elevation acute myocardial infarction without obstructive coronary disease (MINOCA)]. / Incidencia y características clínicas de los pacientes con infarto agudo de miocardio con elevación del ST sin enfermedad coronaria obstructiva (MINOCA).

INTRODUCTION: MINOCA is an acute myocardial infarction without obstructive coronary disease, this definition was recently incorporated into the 4th universal definition of myocardial infarction. However, since it is an unconventional ischemic coronary syndrome in clinical practice, its etiology is very complex to elucidate and requires a differential diagnosis process to rule out other causes of cardiac injury. The objective of this study is to characterize patients with acute myocardial infarction without significant obstructive lesions included in the Argentine Registry of STsegment Elevation Myocardial Infarction (ARGEN-IAM-ST). METHODS: Prospective, multicenter national study including patients with STEMI within 36 hours of symptom onset. All patients studied with coronary angiography at admission were analyzed and those without significant obstructive lesions of the culprit artery were considered MINOCA. This MINOCA patients were compared with patients with significant atherosclerotic coronary lesions. RESULTS: 30 patients with MINOCA out of 2894 patients entered in the registry (incidence: 1%). MINOCA patients were younger, had a similar proportion for gender, had fewer diabetics patients, and had a greater history of heart failure. They were admitted without heart failure and preserved ejection fraction. In-hospital mortality was 7%, with no significant difference compared to classic AMI. At discharge, they received P2Y12 inhibitors, statins, and beta-blockers in fewer proportion. DISCUSSION: There was no predominance of the female gender as in other series. In-hospital mortality is high despite not having significant coronary disease. It is worth mentioning the low use of dual antiaggregating and statins.

Introducción: MINOCA es un infarto agudo de miocardio sin enfermedad coronaria obstructiva, esta definición se ha incorporado recientemente a la 4° definición universal del infarto. Sin embargo, por tratarse de un síndrome coronario isquémico no convencional en la práctica clínica, su etiología es muy compleja de dilucidar y demanda un proceso de diagnósticos diferenciales para descartar otras causas de lesión cardíaca. El objetivo del presente trabajo fue caracterizar a los pacientes con infarto agudo de miocardio sin lesiones obstructivas significativas incluidos en el Registro Argentino de Infarto con Elevación del segmento ST (ARGEN-IAM-ST). Métodos: estudio prospectivo, multicéntrico de carácter nacional con inclusión de pacientes con IAMCEST dentro de las 36 horas comenzado los síntomas. Se analizaron todos los pacientes estudiados con cinecoronariografía al ingreso y se consideró MINOCA a aquellos sin lesiones obstructivas significativas de la arteria responsable y se los comparó con los pacientes con lesiones coronarias ateroscleróticas significativas. Resultados: 30 pacientes con MINOCA sobre 2894 pacientes ingresados al registro (incidencia: 1%). Los pacientes con MINOCA fueron más jóvenes, proporción similar en cuanto al género, menos diabéticos y con más antecedentes de insuficiencia cardíaca. Ingresan sin falla cardíaca y fracción de eyección preservada. Mortalidad intrahospitalaria 7%, sin diferencia significativa comparado con IAM clásico. Al alta recibieron en menor proporción inhibidores P2Y12, estatinas y betabloqueantes. Discusión: No se encontró predominancia de género femenino como otras series. La mortalidad intrahospitalaria es elevada a pesar de no tener enfermedad coronaria significativa. Se destaca la baja utilización de doble antiagregación y estatinas.

Shock Index, Modified Shock Index, and Age-adjusted Shock Index as Predictors of In-hospital Death in Acute Heart Failure. Sub Analysis of the ARGEN IC.

Decompensated heart failure (DHF) is an important cause of in-hospital death in the coronary care unit. Estimating this risk becomes a clinical challenge. The shock index (IShock) and its variances have proven to be useful in predicting mortality in other pathologies and are easily obtained at admission. Evaluate the predictive capacity of IShock and its variants for in-hospital mortality in patients with DHF. Retrospective study of patients (p) prospectively and consecutively included in the ARGEN IC national registry. IShock, was calculated using the formula: HR/TAS, IShockM was calculated using HR/TAM, and IShock adjusted for age was calculated using the formula IShock x age. These indices were analyzed using the ROC curve and the Youden index to find the value that predicted in-hospital mortality with the greatest sensitivity and specificity. The prognostic value of the indices for in-hospital mortality was analyzed. Univariate and multivariate analyses were performed. Patients with cardiogenic shock were excluded from the analysis. Eight hundred seventy-nine patients. Age 74 years (IQR 25-75 64-83). 60% male. 74% hypertensive, 33% diabetic and 42% had ejection fraction <40%. In-hospital mortality was 6.6%. According to Youden 's test, the best value for predicting IShock mortality was 0.9, for IShockM of 1.26 with and for the adjusted IShock of 50.4. The last two showed an independent predictive value in different multivariate models. The IShockM and the IShock x age, taken at the patient´s admission for decompensated heart failure, are very easily obtained at no additional cost providing useful information on hospital major outcomes.

[Prognostic value of the shock index in myocardial infarction. Data from Argentine Registry of ST-segment elevation infarct (ARGEN IAM-ST)]. / Valor pronóstico del índice de shock en el infarto de miocardio. Datos del Registro Argentino de infarto con elevación del segmento ST (ARGEN IAM-ST).

The shock index (IS) is the quotient between the heart rate (HR) and the systolic blood pressure (SBP) (IS: HR / SBT), and the age-adjusted shock index (ISA) multiplying the IS by age. We evaluated its predictive value for the combined in-hospital event (EC), death and / or cardiogenic shock (CS) and for individual events in the patients included in the Argentine registry of ST-segment elevation infarction (ARGEN-ST-AMI); 248 with CS on admission were excluded. ROC curves were made for both indices using the best cut-off point to dichotomize the population. The analysis included 2928 subjects. Age (median) 60 years (IQR 25-75% 53-68), men 80%, EC: 6.4%; 30.5% had IS = 0.67, and they had a higher incidence of EC: 11% vs. 4% (p < 0.001), cardiogenic shock (8% vs. 2.6%, p <0.0001) and death (7.3% vs. 3%), p <0.0001) than patients with IS < 0.67. A 28% had ISA = 41.5. These presented plus EC: 14% vs. 3%, p < 0.001, SC: 10% vs. 2%, (p < 0.001) and death: 9.5% vs. 2.3%, (p < 0.001) compared with patients with values < 41.5. The area under the ROC curve of the ISA for EC was significantly better than that of the IS (0.72 vs. 0.62, p < 0.001). In the multivariate analysis models performed, the IS had an OR: 2.56 (95% CI 1.56-4.02; p < 0.001) and the ISA: 3.43 (95% CI 2.08-5.65; p < 0.001) for EC. The IS and ISA predict death and / or the development of in-hospital cardiogenic shock in an unselected population of ST elevation infarcts.

El índice de shock (IS) se obtiene mediante un cálculo simple del cociente entre la frecuencia cardíaca (FC) y la tensión arterial sistólica (PAS) (IS: FC/TAS) y el índice de shock ajustado por edad (ISA) multiplicando el IS x edad. Evaluamos su valor predictivo para el evento combinado intrahospitalario (EC) muerte y/o shock cardiogénico (SC) y de los eventos individuales en los pacientes incluidos en el registro argentino de infarto con elevación del segmento ST (ARGEN-IAM-ST). Se excluyeron 248 con SC de ingreso. Se realizaron curvas ROC para ambos índices utilizando el mejor punto de corte para dicotomizar la población. Se incluyeron 2928 pacientes. Edad (mediana) 60 años (RIC 25-75% 53-68), varones 80%, EC: 6.4%. Un 30.5% tuvo IS = 0.67 y éstos presentaron mayor incidencia de EC: 11% vs. 4% (p < 0.001), shock cardiogénico (8% vs. 2.6%, p <0.0001) y muerte (7.3% vs. 3%, p < 0.0001) que los pacientes con IS < 0.67. Un 28% tuvo ISA = 41.5. Estos presentaron más EC: 14% vs. 3%, p < 0.001, SC: 10% vs. 2%, (p < 0.001) y muerte: 9.5% vs. 2.3%, (p < 0.001) comparados con los pacientes con valores ISA < 41.5. El área bajo la curva ROC del ISA para EC fue significativamente mejor que la del IS (0.72 vs. 0.62, p < 0.001).En los modelos de análisis multivariados realizados, el IS tuvo un OR de 2.56 (IC95% 1.56-4.02; p < 0.001) y el ISA de 3.43 (IC95% 2.08-5.65; p <0.001) para EC. El IS y el ISA predicen muerte y/o el desarrollo de shock cardiogénico intrahospitalario en una población no seleccionada de infartos con elevación del ST.

[MANAGEMENT RECOMMENDATIONS FOR DIRECT ORAL ANTICOAGULANTS (DOACs) ANTI Xa AND ANTI IIa]. / RECOMENDACIONES DE MANEJO DE LOS ANTICOAGULANTES ORALES DIRECTOS (DOACS) ANTI Xa Y ANTI IIa.

Direct oral anticoagulants have emerged as the drugs that have changed the management of the antithrombotic treatment in the last 15 years. Their advantages, like a more friendly way of anticoagulation and their lower risk of bleeding, especially in the brain, have positioned these new anticoagulants as the first drug of choice in the two most frequent indications of anticoagulation, atrial fibrillation, and the venous thromboembolic disease. However, not all the patients can receive these agents, not all the direct oral anticoagulants have the same characteristics, and most importantly, not all the diseases with an indication of an anticoagulant drug can be treated with them. Therefore, it is mandatory that all the faculties involved in the management of these drugs must know them in depth, to decide the best treatment for the patient. This position paper, from a group of experts in anticoagulation in Argentina, can help the general practitioner in the daily use of direct oral anticoagulants based on the new evidence and the experience of a wide group of professionals. The way we relate to the anticoagulant treatment has changed in the last years. The doctors who work with them must also do so.

Los anticoagulantes orales directos han surgido como una de las herramientas que ha cambiado el manejo de la enfermedad trombótica en los últimos 15 años. Sus ventajas, desde el punto de vista de la facilidad de uso y menor riesgo de sangrado, especialmente de sangrado cerebral, han posicionado a estos nuevos anticoagulantes como la primera alternativa de tratamiento en las dos indicaciones más frecuentes en que necesitamos estas drogas, la fibrilación auricular y la enfermedad tromboembólica venosa. Sin embargo, no todos los pacientes pueden recibir estos agentes, no todos los anticoagulantes directos tienen las mismas propiedades y fundamentalmente, no todas las enfermedades con indicación de un anticoagulante pueden tratarse con ellos;con lo cual es necesario que todos los profesionales que están involucrados en el manejo de estos medicamentos estén obligados a conocerlos en profundidad, para poder decidir el mejor tratamiento en cada caso particular. Este documento de posición de expertos de diferentes especialidades de Argentina, presenta lineamientos para el uso correcto de los anticoagulantes directos en base a nueva evidencia y a la experiencia de uso de un amplio grupo de profesionales. La forma de relacionarnos con el tratamiento anticoagulante ha cambiado. Los médicos que trabajamos con ellos también debemos hacerlo.

Diabetes as a Predictor of In-Hospital and One-Year Outcomes After Decompensated Heart Failure.

Diabetes and heart failure are closely interdependent, but its significance in decompensated heart failure (DHF) is not uniformly accepted. OBJECTIVE: To compare mortality between diabetics and nondiabetics with DHF. METHODS AND RESULTS: In-hospital and 1-year mortality of 1004 consecutive patients with DHF: 25.6% diabetics; median age was 81, 53% male. Diabetics were younger, more often male, with higher prevalence of ischemic etiology and reduced ejection fraction. Congestion was the most prevalent finding in both groups. In hospital mortality was 6.3% vs 6.6 % in nondiabetics and diabetics respectively and 1-year mortality was 35.77% in nondiabetics and 29.3% in diabetics. There were no significant differences in mortality at univariate and multivariate analyses. We applied a propensity score restricted to 378 patients, 189 (50%) diabetics and 189 (50%) and no significant differences were found. CONCLUSION: Diabetes had no impact on prognosis in DHF. Advanced age may played a major role in outcomes i thus making less relevant the presence of diabetes.

Mortalidad del infarto agudo de miocardio en la Argentina durante la pandemia de COVID-19. Datos oficiales de las estadísticas vitales del Ministerio de Salud / Acute Myocardial Infarction Mortality in Argentina During the COVID-19 Pandemic. Ministry of Health Vital Statistics Data

RESUMEN Introducción: En todo el mundo, durante la pandemia de COVID-19 los centros asistenciales y especialmente los cuidados intensivos se vieron saturados por los casos de insuficiencia respiratoria aguda producidos por el virus SARS-CoV-2. El aislamiento social, preventivo y obligatorio (ASPO) establecido por Ley N° 27.541 desde el 20 de marzo de 2020, y ampliado por el Decreto N° 260/20 hasta el 31 de diciembre de 2021, determinó el confinamiento en domicilio. Durante el mismo se observó una disminución de las angioplastias coronarias y cirugías cardíacas centrales. La hipótesis de nuestro trabajo es que hubo un incremento de la mortalidad por el infarto agudo de miocardio (IAM) en la Argentina en el periodo de pandemia, dado que es una patología tiempo dependiente y cuya mortalidad es mayormente extrahospitalaria. Objetivos: Evaluar el incremento de la mortalidad general y por COVID-19 en la población ≥ 20 años en el periodo de pandemia y analizar la tendencia de mortalidad del IAM en forma global y segregada por edad y sexo. Material y métodos: Se analizaron las estadísticas vitales publicadas por el Ministerio de Salud de la Argentina. Se consideró período de pandemia de acuerdo con los 2 años del ASPO, y prepandemia al año 2019. Se consideró tasa bruta y específica de mortalidad al (número de defunciones acaecidas en la población de la Argentina durante 1 año / población total en la misma zona a mitad del mismo año) × 1000, global y por IAM respectivamente. Las defunciones por IAM son las consideradas en el CIE-10 como I21, I22. La tendencia de mortalidad se analizó por el análisis lineal de tendencias de proporciones (Chi2 de tendencias; p significativa < 0,05) con Epi-info y se incluyó a la población ≥20 años. En el análisis por edad se dividió a la población en ≥ o < 60 años. Resultados: la mortalidad en pandemia se incrementó un 26% con respecto al año 2019 (p < 0,001) (tabla). Las defunciones por COVID-19 fueron 53 222 y 84 698 para los años 2020 y 2021 respectivamente. La mortalidad por IAM se incrementó un 15%, con un aumento mayor en jóvenes y mujeres. Conclusión: En la pandemia hubo un fuerte incremento de la mortalidad, atribuible al COVID-19, y un incremento de la mortalidad por infarto agudo de miocardio en especial en mujeres y menores de 60 años, probablemente atribuible a los efectos secundarios del ASPO.

ABSTRACT Background: During the COVID-19 pandemic, health care centers and especially intensive care units worldwide were saturated by cases of acute respiratory failure produced by the SARS-CoV-2 virus. Social preventive and mandatory isolation (SPMI), established by law N° 27 541 since March 20, 2020, and extended by Decree N° 260/20 to December 31, 2021, determined home confinement, and during this period coronary angioplasties and central cardiac surgeries decreased. The hypothesis of our study was that during the pandemic acute myocardial infarction (AMI) increased in Argentina, as this is a time-dependent disease, mainly with out-of-hospital mortality. Objectives: The aim of this study was to evaluate general and COVID-19 mortality in the population ≥20 years during the pandemic and analyze the trend of overall and divided by age and sex AMI mortality. Methods: Vital statics published by the Ministry of Health of Argentina were analyzed, considering the pandemic period as the two SPMI years and 2019 as the pre-pandemic period. Overall and AMI gross and specific rate of mortality were considered as (number of deaths taking place in the Argentine population during 1 year / total population in the same zone at midyear) × 1000, respectively. Deaths for AMI were those contemplated in the International Classification of Diseases 10th revision (ICD-10) as I21, I22. The mortality trend was analyzed with linear trend in proportions (Chi2 for trends; significant p < 0.05) using Epi-Info software, and including the ≥20 to >85-year population. In the analysis by age the population was divided into ≥ or < 60 years. Results: During the pandemic mortality increased by 26% with respect to 2019 (p < 0.001) (table). Deaths for COVID-19 were 53 222 and 84 698 for 2020 and 2021, respectively. Acute myocardial infarction mortality increased by 15%, with a greater number of deaths in the young and female population.

Encuesta burnout (¿estás quemado?) en Especialistas de Cardiología SAC / Burnout Survey among SAC Cardiologists

RESUMEN Introducción. Los profesionales de la salud se encuentran expuestos a un fenómeno ocupacional que resulta del estrés crónico en el ámbito laboral llamado síndrome de burnout (SBO). Este se ha convertido en uno de los riesgos laborales psicosociales más importantes en la sociedad actual y genera costos significativos en el ámbito de la salud. Objetivos. Evaluar la prevalencia de SBO por percepción subjetiva y mediante la aplicación del inventario del síndrome del Desgaste Ocupacional "Burnout" de Maslach (MBI) en los especialistas de cardiología del padrón de la Sociedad Argentina de Cardiología (SAC), y las diferencias acordes al sexo. Material y métodos. Estudio observacional, de corte transversal, mediante una encuesta anónima realizada en abril de 2023 a los especialistas del padrón SAC. Se recabaron datos sobre impresión subjetiva de SBO (sentirse "quemado"), sexo, edad, tiempo de ejercicio profesional. Fue opcional completar el inventario MBI (subescalas) para establecer el diagnóstico de burnout. Resultados. Participaron 756 profesionales, 51,4 % fueron mujeres. El 62 % tenían más de 40 años y el 61 % tenía más de 10 años de ejercicio profesional. Del total de médicos encuestados, el 94,4 % eligió realizar el test de Maslach (MBI), siendo esto más frecuente en las mujeres (96,6 % vs 91,3 %, p < 0,001). La prevalencia de SBO por un MBI de alto puntaje (≥67puntos) fue del 75 % y la prevalencia de percepción de SBO fue del 69 % (p < 0,001). De los que se autopercibieron "quemados" (69 %), el 96,8 % contestó el inventario MBI y se confirmó el diagnóstico de SBO por MBI de alto puntaje en el 78 %. De los que se autopercibieron "no quemados" (31 %), el 89,3 % completó el inventario MBI con diagnóstico de SBO en la subescala cansancio emocional (24 %), despersonalización (18 %) y realización personal (10 %) más allá de no tener la impresión subjetiva de estar "quemado". Los menores de 40 años tuvieron más SBO por MBI de alto puntaje (50 % vs 28 %, p= 0,001) al igual que los profesionales con menos de 10 años en el ejercicio de su profesión (45 % vs 20 % en aquellos con tiempo mayor, p < 0,001). El SBO fue más prevalente en las mujeres que en los hombres, tanto por autopercepción (77 % vs 56 %, p < 0,001) como por el inventario de Maslach (80 % vs 74 %, p=0,001), específicamente en la subescala agotamiento emocional (37 % vs 29 %; p < 0,001) y realización personal (37 % vs 41 %, p < 0,001), sin diferencias por sexo en la esfera de despersonalización. Conclusión. El SBO tiene alta prevalencia entre los cardiólogos encuestados, principalmente en mujeres, tanto por autopercepción como por aplicación del inventario MBI. Por otro lado 1 de cada 4 profesionales encuestados que no se autopercibían "quemados" tuvieron un test positivo para SBO. Teniendo en cuenta la alta prevalencia de SBO entre los especialistas en cardiología es imperioso realizar acciones de prevención e intervención concertadas y sostenidas para transformar esta realidad que impacta desfavorablemente tanto en la salud de los pacientes como en la de los propios médicos.

ABSTRACT Background. Healthcare professionals are exposed to an occupational phenomenon as a result of chronic stress in the workplace called burnout syndrome (BOS). Burnout has become one of the most important psychosocial occupational hazards today and generates significant health care costs. Objectives. The aim of our study was to evaluate the subjective perception of the prevalence of BOS among cardiologists of the Argentine Society of Cardiology (SAC) using Maslach Burnout Inventory (MBI), and the differences between sexes. Methods. We conducted an observational, cross-sectional study using an anonymous survey distributed among specialists of the SAC register in April 2023. The information collected included the subjective impression of BOS (feeling "burned out"), sex, age and years of practice. The participants could optionally complete the MBI (subscales) to establish the diagnosis of BOS. Results. A total of 756 professionals participated in the survey; 51.4% were women. Sixty-two percent of the participants were >40 years old, and 61 % had been practicing medicine for more than 10 years. Of all the physicians surveyed, 94.4% completed the MBI, with women more likely to do so than men (96.6% vs. 91.3%, p < 0.001). The prevalence of BOS, assessed by a high MBI score (≥ 67), was 75%, while 69% reported feeling burned out (p < 0.001). Of those who felt burned out (69 %), 96.8 % completed the MBI, and 78% of them received a diagnosis of BOS based on high MBI scores. Of the 31 % who did not feel burned out, 89.3 % completed the MBI. Burnout syndrome was diagnosed in the emotional exhaustion subscale in 24 %, in the depersonalization subscale in 18%, and in the personal accomplishment subscale in 10%. The diagnosis of BOS made by high MBI score was more common in survey participants under 40 years than in older participants (50 % vs. 28 %, p < 0.001) and in professionals who have been practicing medicine for less than 10 years (45 % vs. 20 % in those with more years of practice, p < 0.001). Women were more likely to experience BOS according to their own perception (77 % vs. 56 %, p < 0.001) and MBI score (80 % vs. 74 %, p < 0.001), specifically in the emotional exhaustion (37 % vs. 29 %, p < 0.001) and personal accomplishment (37 % vs. 41 %, p < 0.001) subscales, with No differences by sex in the depersonalization sphere. Conclusion. Burnout syndrome was found to be prevalent among the surveyed cardiologists, particularly in female participants, as indicated by both their own perception and the MBI assessment. In addition, 1 out of 4 professionals surveyed who did not feel "burned out" tested positive for BOS. Given the high prevalence of BOS among cardiologists, coordinated and sustained prevention and intervention actions should be undertaken to change this reality that negatively impacts both patient and physician health.

Encuesta sobre factores de riesgo de enfermedad cardiovascular en la mujer, su percepción, conocimiento y conducta de prevención / Survey on Women's Perception and Awareness of Cardiovascular Risk Factors and How They Are Managed

RESUMEN Introducción : La enfermedad cardiovascular (ECV) es la principal causa de muerte en la mujer. A pesar de esto, las mujeres reciben menos frecuentemente que los hombres asesoramiento y/o tratamiento preventivo con el objetivo de disminuir la ECV. Objetivo : Detectar la prevalencia de factores de riesgo cardiovascular (FRC) y pesquisar el nivel de percepción y conocimiento de la mujer sobre FRC y ECV. Material y métodos : Estudio observacional, de corte transversal realizado en julio 2021, mediante una encuesta en formato digital de participación anónima y voluntaria. Se recabó información sobre edad, FRC, ECV, percepción de riesgo, implemen tación de hábitos y conductas saludables. Resultados : Participaron 3338 mujeres. El 50,1% tenía entre 46 y 65 años. El 34,1% tenía sobrepeso, el 43,6% perímetro de cintura mayor que 80 cm, el 24,2% hipertensión (HTA), el 19,6% colesterol mayor que 200 mg/dL, el 5,4% diabetes (DBT); 44,3% eran sedentarias, 11,3% fumaban y 34,5% eran exfumadoras. El 82,1% tuvo al menos un embarazo y el 26,9% refirió alguna complicación. Entre las pacientes con antecedentes de complicaciones del embarazo fueron significativamente más frecuentes la HTA (34% vs 24%, p <0,01), la DBT (7% vs 5%, p = 0,04) y la ECV (14% vs 11%, p <0,01). Del total de encuestadas 10,9% refirió ECV, el antecedente de infarto de miocardio fue el más frecuente (51,1%). El 62% de las encuestadas consideró que la principal causa de muerte en la mujer es el cáncer, particularmente de mama (53,4%). Conclusiones : Se encontró una alta prevalencia de FRC modificables con baja percepción del riesgo cardiovascular. El antecedente de complicaciones del embarazo se asoció con mayor prevalencia de FRC.

ABSTRACT Background : Cardiovascular disease (CVD) is the leading cause of death in women. Nevertheless, women are less likely than men to receive guidance or preventive treatment to reduce it. Objective : The aim of this study was to detect the prevalence of cardiovascular risk factors (CRF) and detect the level of women's perception and awareness of CRF and CVD. Methods : We conducted an observational, cross-sectional study in July 2021 using a voluntary, anonymous, and online survey. The information collected included age range, CRF, CVD, risk perception and implementation of healthy habits and behaviors. Results : A total of 3888 women participated (with age range between 46 and 65 years in 50.1%); 34.1% had excess weight and 43.6% had a waist circumference > 80 cm. Hypertension (HTN) was reported by 24.2%; total cholesterol was > 200 mg/ dL in 19.6%; 5,4% were diabetics (DM); 44.3% had sedentary lifestyle; 11.3% were current smokers and 34.5% were former smokers; 82.1% had been pregnant at least once and 26.9% reported a complication during pregnancy. A bad obstetric history was more commonly associated with HTN (34% vs. 24%, p < 0.01), DM (7% vs. 5%, p = 0.04) and CVD (14% vs. 11%, p <0.01). Among the 10.9% who reported a history of CVD, myocardial infarction was the most common condition (51.1%). Sixty-two percent of survey respondents considered that cancer, and particularly breast cancer (53.4%), is the main cause of death in women (53.4%). Conclusions : We found a high prevalence of modifiable CRFs with low perception of cardiovascular risk. A bad obstetric history was associated with higher prevalence of CRF.

Registro ARGEN-IAM-ST: infarto de miocardio con elevación del segmento ST en el "nuevo" adulto mayor / ARGEN-IAM-ST Registry: ST-elevation myocardial infarction in "new" older adults

RESUMEN Introducción: La Organización Mundial de la Salud (OMS) considera adulto mayor (AM) a las personas que tienen 60 años o más. Es sabido que la mortalidad por infarto agudo de miocardio (IAM) aumenta a edades más avanzadas, pero siempre se han utilizado umbrales de edad mayores que el propuesto por la OMS, por lo cual describir las características y evolución intrahospitalaria de este subgrupo (de acuerdo con la definición de la OMS) se torna relevante. Objetivos: 1) conocer la prevalencia de los AM según la OMS, con IAM con elevación del segmento ST en Argentina y 2) com- parar sus características, tratamientos de reperfusión y mortalidad con los adultos jóvenes. Material y métodos: Se analizaron los pacientes ingresados en el Registro Nacional de Infarto (ARGEN-IAM-ST). Se compara- ron las características clínicas, tratamientos y evolución de los AM y los adultos jóvenes. Resultados: Se incluyeron 6676 pacientes, de los cuales 3626 (54,3%) eran AM. Los AM fueron más frecuentemente mujeres (37,6% vs. 31,4%, p <0,001), hipertensos (67,8% vs. 47%, p <0,001), diabéticos (26,1% vs. 19,9%, p <0,001), dislipidémicos (45,4% vs. 37%, p <0,001), y tuvieron más antecedentes coronarios (16% vs. 10,3%, p <0,001). El tiempo a la consulta de los AM fue mayor (120 min vs. 105 min, p <0,001) con similar tiempo total de isquemia (314 min vs. 310 min, p = 0,33). Recibi- eron menos tratamiento de reperfusión (89,9% vs. 88,6%, p = 0,04) y más angioplastia primaria (91 % vs. 87,4%, p <0,001). Tuvieron más insuficiencia cardíaca (27,3% vs. 18,5%, p <0,001), similar incidencia de sangrado (3,7 vs. 3,1%, p = 0,33) y una mortalidad significativamente mayor (11,4% vs. 5,5%, p <0,001). Ser AM fue predictor independiente de mortalidad. Conclusiones: Más de la mitad de los IAM en nuestro país ocurren en AM. Los pacientes mayores tienen menor probabilidad de recibir reperfusión, más insuficiencia cardíaca y el doble de la mortalidad que los pacientes menores de 60 años.

ABSTRACT Background: The World Health Organization (WHO) defines an Older Adult (OA) as any individual aged 60 or older. It is known that mortality due to acute myocardial infarction (AMI) increases with age, but age thresholds higher than those proposed by the WHO have been consistently used; therefore, describing the characteristics and in-hospital progress of this subgroup of patients, in accordance with the WHO definition, becomes relevant. Objectives: 1) To know the prevalence of OA with acute ST-elevation myocardial infarction (STEMI) in Argentina according to the WHO, and 2) to compare their characteristics, reperfusion treatments, and mortality against those in young adults. Methods: Patients included in the National Registry of ST- Elevation Myocardial Infarction (Registro Nacional de Infarto con Elevación del ST, ARGEN-IAM-ST) were analyzed. Clinical features, therapies, and progress were compared in OA versus young adults. Results: A total of 6676 patients were enrolled, 3626 of which (54.3%) were OA. OA were mostly female (37.6% vs 31.4%, p <0.001), had hypertension (67.8% vs 47%, p <0.001), diabetes (26.1% vs 19.9%, p <0.001), dyslipidemia (45.4% vs 37%, p <0.001), and a longer coronary artery disease history (16% vs 10.3%, p < 0.001). The time to consultation in OA was longer (120 min vs 105 min, p <0.001), with a similar total ischemic time (314 min vs 310 min, p = 0.33). They received less reperfu- sion treatment (89.9% vs 88.6%, p = 0.04) and more primary angioplasty (91% vs 87.4%, p <0.001). Heart failure was more common in OAs (27.3% vs 18.5%, p <0.001), with a similar bleeding incidence (3.7% vs 3.1%, p = 0.33), and significantly higher mortality (11.4% vs 5.5%, p<0.001). Being an OA was an independent mortality predictor. Conclusions: More than half the cases of AMI in our country occur in OA. Older patients are less likely to receive reperfusion, more likely to have heart failure, and show twice the rate of mortality as compared to patients under 60.

Utilización de la estrategia farmacoinvasiva en Argentina. Análisis del registro ARGEN-IAM ST / Use of the Pharmacoinvasive Strategy in Argentina. ARGEN-IAM ST Registry Analysis

RESUMEN Introducción : La angioplastia primaria (ATCp) es el tratamiento de elección para el infarto agudo de miocardio con elevación del segmento ST (IAMCEST). En nuestro país, de tanta extensión territorial y con tiempos a la reperfusión subóptimos, la estrategia farmacoinvasiva (Finv) podría considerarse. Material y métodos : El ARGEN-IAM-ST es un registro prospectivo, multicéntrico, nacional y observacional. Se incluyen pacien tes con IAMCEST dentro de las 36 horas de evolución. Se definió en el mismo la utilización de Finv y las variables asociadas. Resultados : Se analizaron 4788 pacientes de los cuales en el 88,56 % se realizó ATCp, en el 8,46 % trombolíticos con reperfusión positiva (TL+), y solo en un 2,98% Finv. La mediana y rango intercuartílico (RIC) del tiempo total de isquemia fueron menores en aquellos que recibieron TL+ (165 min, RIC 100-269) y los que fueron a Finv (191 min, RIC 100-330) que en aquellos que fueron a ATCp (280 min, RIC 179- 520), p <0,001. No existieron diferencias en mortalidad intrahospitalaria, en el grupo Finv 4,9%, 5,2% en el grupo TL + y en el grupo ATCp 7,8% (p = 0,081). No hubo diferencias en término de sangrados mayores. Se observó que un 57% de los pacientes con TL+ reunían características de alto riesgo, y no recibieron Finv acorde a lo recomendado Conclusiones : Solo 3 de cada 100 pacientes con IAMCEST que se reperfunden reciben Finv. Su implementación no está ligada en forma sistemática al alto riesgo de eventos. Pese a esta subutilización, por presentar un menor tiempo total de isquemia que la ATCp, sin aumento en los sangrados clínicamente relevantes persiste como una opción a considerar en nuestra realidad.

ABSTRACT Background : Primary percutaneous coronary intervention (PPCI) is the treatment of choice for acute ST-elevation myocardial infarction (STEMI). In Argentina, a country with a large area and suboptimal reperfusion times, the pharmacoinvasive (PI) strategy might be considered. Methods : ARGEN-IAM-ST is a national prospective, multicenter, and observational registry that includes STEMI patients with less than 36 hours of progression. The PI strategy usage and its associated variables were defined. Results : In this registry, 4788 patients were analyzed, of which 88.56% underwent PPCI, 8.46% received thrombolytics with positive reperfusion (TL+), and only 2.98% received PI strategy. Median and interquartile range (IQR) of total ischemia time were lower in patients receiving TL+ (165 min, IQR 100-269) and PI (191 min, IQR 100-330) than in patients undergoing PPCI (280 min, IQR 179-520), p <0.001. No differences in intra-hospital mortality were observed: 4.9% in the PI strategy group, 5.2% in the TL+ group and 7.8% in the PPCI group (p = 0.081). No differences in major bleeding events were observed. It was observed that 57% of the TL+ patients met the criteria for high cardiovascular risk, but they did not receive PI strategy, as recommended. Conclusions : Only 3 out of 100 reperfused STEMI patients received PI strategy. Its administration is not systematically associated to high cardiovascular risk. Despite the under-usage, it remains an option to be considered due to its total ischemia time lower than in the PPCI, with no increase in clinically significant bleedings.

Validity, reliability, feasibility and satisfaction of the Mini-Clinical Evaluation Exercise (Mini-CEX) for cardiology residency training.

AIMS: The purpose of the study was to determine the validity, reliability, feasibility and satisfaction of the Mini-CEX. METHODS AND RESULTS: From May 2003 to December 2004, 108 residents from 17 cardiology residency programs in Buenos Aires were monitored by the educational board of the Argentine Society of Cardiology. Validity was evaluated by the instrument's capability to discriminate between pre-existing levels of clinical seniority. For reliability, generalisability theory was used. Feasibility was defined by a minimum number of completed observations: 50% of the residents obtaining at least four Mini-CEX's. Satisfaction was evaluated through a one to nine rating scale from the evaluators, and residents' perspectives. The total number of encounters was 253. Regarding validity, Mini-CEX was able to discriminate significantly between residents of different seniority. Reliability analysis indicated that a minimum of ten evaluations are necessary to produce a minimally reliable inference, but more are preferable. Feasibility was poor: 15% of the residents were evaluated four or more times during the study period. High satisfaction ratings from evaluators' and residents' were achieved. CONCLUSION: Mini-CEX discriminates between pre-existing levels of seniority, requires considerable sampling to achieve sufficient reliability, and was not feasible within the current circumstances, but it was considered a valuable assessment tool as indicated by the evaluators' and residents' satisfaction ratings.

Equidad laboral, violencia de género y factores de riesgo cardiovascular en especialistas en cardiología argentinos / Labor Equity, Gender Violence and Cardiovascular Risk Factors in Cardiology Specialists

RESUMEN Los especialistas en cardiología pueden sufrir estresores que afecten su salud, como inequidad laboral y violencia de género, además de padecer factores de riesgo (FR) tradicionales para enfermedad cardiovascular (ECV) Objetivo: Detectar el nivel de bienestar, equidad laboral y violencia de género y conocer la prevalencia de los FR en especialistas en cardiología en Argentina Material y métodos: Estudio observacional, de corte transversal a través de una encuesta anónima realizada en septiembre de 2021 a los especialistas del padrón de la Sociedad Argentina de Cardiología. Se recabaron datos sobre equidad laboral, violencia laboral y doméstica y FR. Resultados: Participaron 611 profesionales (40,5% mujeres). El 63% trabajaba más de 44 horas semanales; 3 de cada 10 cumplían guardias de 12 o 24 horas (38,5% mujeres vs 28% varones, p <0,01). El 72% consideró excesiva la carga laboral, con remuneración no acorde a su formación académica (70%). La mitad de las cardiólogas encuestadas consideró que la maternidad limitó el desarrollo profesional en la especialidad. La violencia de género laboral fue más frecuente en las cardiólogas (58% vs 10% p <0,01) al igual que la violencia doméstica (16% vs 6% p <0,01). Los varones tenían más sobrepeso (67% vs 34% mujeres, p <0,01) y obesidad (16% vs 11%, p<0,01) y las mujeres resultaron ser más sedentarias (53% vs 45%, p< 0,01). Conclusión: Resultó evidente la disconformidad en las condiciones laborales en ambos sexos y la mayor prevalencia de violencia de género laboral y doméstica en las especialistas mujeres encuestadas. A pesar de contar con el conocimiento sobre ECV y FR los especialistas encuestados tienen una alta prevalencia de FR.

ABSTRACT Background: Cardiology specialists may suffer from stressors that affect their health, such as labor inequity and gender violence, in addition to traditional cardiovascular risk factors (RF) for cardiovascular disease (CVD). Objective: The aim of this study was to detect the level of well-being, labor equity and gender violence and to establish the prevalence of CRF in cardiology specialists in Argentina. Methods: This was an observational, cross-sectional study through an anonymous survey conducted in September 2021 among specialists included in the Argentine Society of Cardiology registry. Data on labor equity, labor and domestic violence and CRF were collected. Results: Six hundred and eleven professionals (40.5% women) participated in the survey: 63% worked more than 44 hours per week; 3 out of 10 were on duty for 12 or 24 hours (38.5% women vs. 28% men, p<0.01). Seventy-two percent of respondents considered the workload excessive while 70% thought their payment was not in accordance with the academic training. Half of female cardiologists surveyed considered that motherhood limited professional development in the specialty. Work-related violence was more frequent in female cardiologists (58% vs. 10% p <0.01), as was domestic violence (16% vs. 6% p <0.01). Men were more overweight (67% men vs. 34% women, p <0.01) and obese (16% vs. 11%, p <0.01) and women were more sedentary (53% vs. 45%, p <0.01). Conclusion: The disconformity in working conditions experienced by both genders was evident, as was the evidence of higher workplace and domestic gender violence in the female specialists surveyed. Despite having knowledge about CVD and cardiovascular RF, the surveyed specialists have a high prevalence of RF.

Incidencia y características clínicas de los pacientes con infarto agudo de miocardio con elevación del ST sin enfermedad coronaria obstructiva (MINOCA) / Incidence and clinical characteristics of patients with ST-elevation acute myocardial infarction without obstructive coronary disease (MINOCA)

Resumen Introducción: MINOCA es un infarto agudo de miocardio sin enfermedad coronaria obstructiva, esta definición se ha incorporado recientemente a la 4° definición universal del infarto. Sin embargo, por tratarse de un síndrome coronario isquémico no convencional en la práctica clínica, su etiología es muy compleja de dilucidar y demanda un proceso de diagnósticos diferenciales para descartar otras causas de lesión cardíaca. El objetivo del presente trabajo fue caracterizar a los pacientes con infarto agudo de miocardio sin lesiones obstructivas significativas incluidos en el Registro Argentino de Infarto con Elevación del segmento ST (ARGEN-IAM-ST). Métodos: estudio prospectivo, multicéntrico de carácter nacional con inclusión de pacientes con IAMCEST dentro de las 36 horas comenzado los síntomas. Se analizaron todos los pacientes estudiados con cinecoronariografía al ingreso y se consideró MINOCA a aquellos sin lesiones obstructivas significativas de la arteria responsable y se los comparó con los pacientes con lesiones coronarias ateroscleróticas signifi cativas. Resultados: 30 pacientes con MINOCA sobre 2894 pacientes ingresados al registro (incidencia: 1%). Los pacientes con MINOCA fueron más jóvenes, proporción similar en cuanto al género, menos diabéticos y con más antecedentes de insuficiencia cardíaca. Ingresan sin falla cardíaca y fracción de eyección preservada. Mortalidad intrahospitalaria 7%, sin diferencia significativa comparado con IAM clásico. Al alta recibieron en me nor proporción inhibidores P2Y12, estatinas y betabloqueantes. Discusión: No se encontró predominancia de género femenino como otras series. La mortalidad intrahospitalaria es elevada a pesar de no tener enfermedad coronaria significativa. Se destaca la baja utilización de doble antiagregación y estatinas.

Abstract Introduction: MINOCA is an acute myocardial infarction without obstructive coronary disease, this definition was recently incorporated into the 4th universal definition of myocardial infarction. However, since it is an unconventional ischemic coronary syndrome in clinical practice, its etiology is very complex to elucidate and requires a differential diagnosis process to rule out other causes of cardiac injury. The objective of this study is to characterize patients with acute myocardial infarction without significant obstructive lesions included in the Argentine Registry of ST-segment Elevation Myocardial Infarction (ARGEN-IAM-ST). Methods: Prospective, multicenter national study including patients with STEMI within 36 hours of symptom onset. All patients studied with coronary angiography at admission were analyzed and those without significant obstructive lesions of the culprit artery were considered MINOCA. This MINOCA patients were compared with patients with significant atherosclerotic coronary lesions. Results: 30 patients with MINOCA out of 2894 patients entered in the registry (incidence: 1%). MINOCA patients were younger, had a similar proportion for gender, had fewer diabetics patients, and had a greater history of heart failure. They were admitted without heart failure and preserved ejection fraction. In-hospital mortality was 7%, with no significant difference compared to classic AMI. At discharge, they received P2Y12 inhibitors, statins, and beta-blockers in fewer proportion. Discussion: There was no predominance of the female gender as in other series. In-hospital mortality is high despite not having significant coronary disease. It is worth mentioning the low use of dual antiaggregating and statins.

Características generales y evolución según el índice de masa corporal en pacientes con Infarto Agudo de Miocardio en Argentina. (Registro ARGEN-IAM-ST) / General Characteristics and Outcome of Patients with Acute Myocardial Infarction in Argentina According to Body Mass Index. (ARGEN-IAM-ST Registry)

RESUMEN Introducción: El índice de masa corporal (IMC) en rangos de sobrepeso y obesidad es un factor de riesgo cardiovascular cada vez más frecuente. Su valor pronóstico es discutido en el contexto del infarto agudo de miocardio (IAM). Objetivos: Conocer características basales, estrategias de reperfusión y evolución de los casos incluidos del registro ARGENIAM ST según el IMC. Material y Métodos: Estudio prospectivo de los casos incluidos en el registro. Se excluyeron los que no presentaban datos antropométricos completos. Se definieron 3 grupos; IMC saludable: < 25 kg/m2 (G1), sobrepeso: IMC entre 25 y 29,9 kg/m2 (G2) y obesidad: IMC mayor o igual a 30 kg/m2 (G3). Resultados: Se incluyeron 2925 casos. Los pacientes del G3 tenían menor edad (G1: 63 ± 12, G2: 61 ± 11, G3: 60 ± 11 años, p = 0,0001), más frecuentemente diabetes (G1: 11%, G2: 22%, G3: 28%; p = 0,0001) y dislipidemia (G1: 35%, G2: 40%, G3: 43%; p = 0,01). No encontramos diferencias en el tiempo puerta balón, (medianas de 104 minutos en G1, 110 en G2 y 110 en G3, p = 0,27), la enfermedad de dos o más vasos (G1 38%, G2 34,5% y G3 37%; p = 0,26) y la mortalidad intrahospitalaria (G1 9,7%, G2 7,5% y G3 8,4%; p = 0,22). En el análisis multivariado el Killip y Kimball no A (OR: 20,1; IC95% 13,1-30,8; p < 0,0001), la edad (OR: 1,7; IC95 1,2-2,5; p <0,0001) y la enfermedad de dos o más vasos (OR: 1.5; IC95% 1,03-2,1; p < 0,0001) fueron predictores independientes de mortalidad en la internación. Conclusiones: Los pacientes con sobrepeso y obesidad eran más jóvenes, con más antecedentes de diabetes y dislipidemia. No hubo diferencias significativas en la forma de presentación, tratamiento y complicaciones. En el análisis multivariado el sobrepeso y la obesidad no fueron predictores de mortalidad.

ABSTRACT Background: Body mass index (BMI) in overweight and obesity ranges is an increasingly frequent cardiovascular risk factor. Its prognostic value is debatable in the setting of acute myocardial infarction (AMI). Objectives: The aim of this study is to acknowledge the clinical characteristics, reperfusion strategies outcome of the cases included in the ARGEN-IAM ST according to BMI. Methods: We conducted a prospective study of the cases included in the registry. Patients with incomplete anthropometric data were excluded. Three groups were defined: healthy BMI < 25 kg/m2 (G1), overweight: BMI between 25 and 29.9 kg/m2 (G2) and obesity: BMI ≥30 kg/m2 (G3). Results: 2925 cases were included. Patients in G3 were younger (G1: 63±12, G2: 61±11, G3: 60±11 years, p=0.0001), and had higher incidence of diabetes (G1: 11%, G2: 22%, G3: 28%; p=0.0001) and dyslipidemia (G1: 35%, G2: 40%, G3: 43%; p=0.01). There were no differences in door-to-balloon time (median 104 minutes in G1, 110 in G2 and 110 in G3, p=0.27), two-vessel disease or greater (G1 38%, G2 34.5% and G3 37%; p=0.26) and in-hospital mortality (G1 9.7%, G2 7.5% and G3 8.4%; p=0.22). In multivariate analysis Killip class other than A (OR: 20.1; 95% CI 13.1-30.8; p<0.0001), age (OR: 1.7; 95% CI 1.2-2.5; p<0.0001) and two-vessel disease or greater (OR: 1.5; 95% CI 1.03-2.1; p<0.0001) were independent predictors of in-hospital mortality. Conclusions: Overweight and obese patients were younger, with higher incidence of diabetes and dyslipidemia. There were no significant differences in the type of presentation, treatment and complications. In multivariate analysis, overweight and obesity were not predictors of mortality.

Valor pronóstico del índice de shock en el infarto de miocardio. Datos del Registro Argentino de infarto con elevación del segmento ST (ARGEN IAM-ST) / Prognostic value of the shock index in myocardial infarction. Data from Argentine Registry of ST-segment elevation infarct (ARGEN IAM-ST)

Resumen El índice de shock (IS) se obtiene mediante un cálculo simple del cociente entre la frecuencia cardíaca (FC) y la tensión arterial sistólica (PAS) (IS: FC/TAS) y el índice de shock ajustado por edad (ISA) multiplicando el IS x edad. Evaluamos su valor predictivo para el evento combinado intrahospitalario (EC) muerte y/o shock cardiogénico (SC) y de los eventos individuales en los pacientes incluidos en el registro argentino de infarto con elevación del segmento ST (ARGEN-IAM-ST). Se excluyeron 248 con SC de ingreso. Se realizaron curvas ROC para ambos índices utilizando el mejor punto de corte para dicotomizar la población. Se incluyeron 2928 pacientes. Edad (mediana) 60 años (RIC 25-75% 53-68), varones 80%, EC: 6.4%. Un 30.5% tuvo IS ≥ 0.67 y éstos presentaron mayor incidencia de EC: 11% vs. 4% (p < 0.001), shock cardiogénico (8% vs. 2.6%, p <0.0001) y muerte (7.3% vs. 3%, p < 0.0001) que los pacientes con IS < 0.67. Un 28% tuvo ISA ≥ 41.5. Estos presentaron más EC: 14% vs. 3%, p < 0.001, SC: 10% vs. 2%, (p < 0.001) y muerte: 9.5% vs. 2.3%, (p < 0.001) comparados con los pacientes con valores ISA < 41.5. El área bajo la curva ROC del ISA para EC fue significativamente mejor que la del IS (0.72 vs. 0.62, p < 0.001).En los modelos de análisis multivariados reali zados, el IS tuvo un OR de 2.56 (IC95% 1.56-4.02; p < 0.001) y el ISA de 3.43 (IC95% 2.08-5.65; p<0.001) para EC. El IS y el ISA predicen muerte y/o el desarrollo de shock cardiogénico intrahospitalario en una población no seleccionada de infartos con elevación del ST.

Abstract The shock index (IS) is the quotient between the heart rate (HR) and the systolic blood pressure (SBP) (IS: HR / SBT), and the age-adjusted shock index (ISA) multiplying the IS by age. We evaluated its predictive value for the combined in-hospital event (EC), death and / or cardiogenic shock (CS) and for individual events in the patients included in the Argentine registry of ST-segment elevation infarction (ARGEN-ST-AMI); 248 with CS on admission were excluded. ROC curves were made for both indices using the best cut-off point to dichotomize the population. The analysis included 2928 subjects. Age (median) 60 years (IQR 25-75% 53-68), men 80%, EC: 6.4%; 30.5% had IS ≥ 0.67, and they had a higher incidence of EC: 11% vs. 4% (p < 0.001), cardiogenic shock (8% vs. 2.6%, p <0.0001) and death (7.3% vs. 3%), p <0.0001) than patients with IS < 0.67. A 28% had ISA ≥ 41.5. These presented plus EC: 14% vs. 3%, p < 0.001, SC: 10% vs. 2%, (p < 0.001) and death: 9.5% vs. 2.3%, (p < 0.001) compared with patients with values < 41.5. The area under the ROC curve of the ISA for EC was significantly better than that of the IS (0.72 vs. 0.62, p < 0.001). In the multivariate analysis models performed, the IS had an OR: 2.56 (95% CI 1.56-4.02; p < 0.001) and the ISA: 3.43 (95% CI 2.08-5.65; p < 0.001) for EC. The IS and ISA predict death and / or the development of in-hospital cardiogenic shock in an unselected population of ST elevation infarcts.

Recomendaciones de manejo de los anticoagulantes orales directos (DOACs) anti Xa y anti IIa / Recommendations for the practical management of the direct oral anticoagulants anti Xa and anti IIa

Resumen Los anticoagulantes orales directos han surgido como una de las herramientas que ha cambiado el manejo de la enfermedad trombótica en los últimos 15 años. Sus ventajas, desde el punto de vista de la facilidad de uso y menor riesgo de sangrado, especialmente de sangrado cerebral, han posicionado a estos nuevos anticoagulantes como la primera alternativa de tratamiento en las dos indicaciones más frecuentes en que necesitamos estas drogas, la fibrilación auricular y la enfermedad tromboembólica venosa. Sin embargo, no todos los pacientes pueden recibir estos agentes, no todos los anticoagulantes directos tienen las mismas pro piedades y fundamentalmente, no todas las enfermedades con indicación de un anticoagulante pueden tratarse con ellos;con lo cual es necesario que todos los profesionales que están involucrados en el manejo de estos medicamentos estén obligados a conocerlos en profundidad, para poder decidir el mejor tratamiento en cada caso particular. Este documento de posición de expertos de diferentes especialidades de Argentina, presenta lineamientos para el uso correcto de los anticoagulantes directos en base a nueva evidencia y a la experiencia de uso de un amplio grupo de profesionales. La forma de relacionarnos con el tratamiento anticoagulante ha cambiado. Los médicos que trabajamos con ellos también debemos hacerlo.

Abstract Direct oral anticoagulants have emerged as the drugs that have changed the man agement of the antithrombotic treatment in the last 15 years. Their advantages, like a more friendly way of anticoagulation and their lower risk of bleeding, especially in the brain, have positioned these new anticoagu lants as the first drug of choice in the two most frequent indications of anticoagulation, atrial fibrillation, and the venous thromboembolic disease. However, not all the patients can receive these agents, not all the direct oral anticoagulants have the same characteristics, and most importantly, not all the diseases with an indication of an anticoagulant drug can be treated with them. Therefore, it is mandatory that all the faculties involved in the management of these drugs must know them in depth, to decide the best treatment for the patient. This position paper, from a group of experts in anticoagulation in Argentina, can help the general practitioner in the daily use of direct oral anticoagulants based on the new evidence and the experience of a wide group of professionals. The way we relate to the anticoagulant treatment has changed in the last years. The doctors who work with them must also do so.
