RESUMO

RESUMEN Introducción. La miocardiopatía hipertrófica (MCH), es la enfermedad genética cardiovascular más común, causada por mutaciones en proteínas del sarcómero cardíaco, con una prevalencia considerable y clínica variable, desde asintomática hasta insuficiencia cardíaca y muerte súbita. Existen pacientes seguidos en centros no especializados, y es necesario conocer datos que puedan mostrar la realidad de su diagnóstico, tratamiento y pronóstico. Objetivo. Conocer las características clínicas, estrategias diagnósticas y terapéuticas al abordar la MCH en centros no especializados en la patología. Material y métodos. Estudio de corte transversal, multicéntrico, de alcance nacional, con análisis cuantitativo, de pacientes con MCH confirmada o altamente probable. Resultados. Se registraron 95 pacientes, mayormente hombres con hipertensión arterial (40 %) y dislipidemia (22 %) como principales factores de riesgo. Se observó baja proporción de comorbilidades: enfermedad pulmonar obstructiva crónica (6 %), infarto de miocardio previo (5 %), accidente cerebro vascular previo (1 %) e insuficiencia renal crónica (1 %). Los síntomas principales fueron la disnea (47 %) y el ángor (27 %), y los métodos diagnósticos más usados fueron el ecocardiograma (97 %) y la resonancia cardíaca (71 %). La localización más frecuente fue septal, con 37 % de tipo obstructivo. El test genético, realizado en un 33 %, fue positivo en más de la mitad de los pacientes. No se realizó en dos tercios de los casos principalmente por falta de cobertura. Conclusiones. Los hallazgos son concordantes con los de registros internacionales. Con base a nuestros hallazgos, se resalta la necesidad de mejorar el acceso a estudios diagnósticos más complejos y optimizar recursos en un sistema de salud fragmentado.


ABSTRACT Background . Hypertrophic cardiomyopathy (HCM) is the most common genetic disease caused by cardiac sarcomere protein mutations, with considerable prevalence and different clinical presentation, varying from asymptomatic to heart failure and sudden death. Some patients are followed-up in nonspecialized centers, and it is necessary to know data that show the reality of their diagnosis, treatment, and prognosis. Objective. The aim of this study was to know the clinical characteristics, and diagnostic and therapeutic strategies when HCM is managed in centers not specialized in this disease. Methods. This was a national, cross-sectional, multicenter study, with quantitative analysis of patients with confirmed or highly probable HCM. Results. A total of 95 patients were recruited, mostly men, with hypertension (40%) and dyslipidemia (22%) as main risk factors. A low proportion of comorbidities was observed: chronic obstructive pulmonary disease (6%), prior myocardial infarction (5%), prior stroke (1%) and chronic kidney failure (1%). The main symptoms were dyspnea (47% and angina (27%), and the most used diagnostic methods were echocardiogram (97%) and cardiac magnetic resonance imaging (71%)). The most frequent localization was septal, with 37% of hypertrophic obstructive cardiomyopathy. The genetic test, performed in 33% of patients, was positive in more than half of cases. It was not performed in the rest of the patients, mainly due to lack of health coverage. Conclusions. These findings are in agreement with international registries. Based on our findings, emphasis should be placed in improving the access to more complex diagnostic studies and optimizing the resources in a fragmented health system.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

RESUMEN Introducción: El índice de shock (IShock), calculado a partir de los valores al ingreso de la frecuencia cardíaca (FC) y tensión arterial sistólica (TAS) y el IShock ajustado por edad, son herramientas que han demostrado utilidad pronóstica en algunos contextos clínicos; sin embargo, su valor pronóstico en la insuficiencia cardíaca descompensada (ICD) es desconocido. Objetivo: evaluar la capacidad pronóstica para mortalidad total intrahospitalaria de ambos índices en pacientes ingresados a unidad coronaria por ICD. Material y métodos: Estudio retrospectivo de pacientes consecutivos ingresados en 2 unidades coronarias durante el periodo enero 2010/agosto 2020. Se calcularon ambos índices, se determinó su valor predictivo y mediante curva ROC se definieron los valores de corte con mejor combinación de sensibilidad y especificidad. Se efectuó análisis multivariado para encontrar los predictores independientes de mortalidad intrahospitalaria. Resultados: Población: 1472 pacientes. Edad (mediana) 81 años, 50% con fracción de eyección ventricular izquierda <40%, y 50% con antecedentes de ICD previa. Mortalidad intrahospitalaria 6,2%. Un IShock ≥0,58 e IShock ajustado por edad ≥45,6 (hallados por índice de Youden) fueron predictores de mortalidad. En el análisis multivariado que incluyó edad, tensión arterial sistólica (TAS) <115 mmHg, nitrógeno ureico en sangre (BUN) >43 mg/dL, creatinina >2,75 mg/dL, hemoglobina <10 g/dL y el ISHock ≥0,58, solo mantuvieron su valor predictivo la edad, el BUN >43 mg/dL y la anemia. En un modelo multivariado donde se evaluó al IShock ajustado por edad ≥45,6 junto a las otras variables (excepto edad), éste fue predictor independiente (OR 2,41 IC95% 1,37-4,2 p <0,01) al igual que el BUN >43 mg/dL y la anemia. Conclusión: Un cálculo sencillo como el IShock ajustado por edad es de gran utilidad en la predicción de la mortalidad hospitalaria de los pacientes internados con ICD y agrega información adicional a las variables pronósticas clásicas.


ABSTRACT Background: Shock index (SI), calculated as the ratio of heart rate (HR) to systolic blood pressure (SBP) obtained on admission, and age-adjusted SI are tools that have already demonstrated prognostic value in some clinical contexts, but their prognostic value in decompensated heart failure (DHF) is unknown. Objective: The aim of this study was to evaluate the prognostic ability of both indices for total in-hospital mortality in patients admitted to the coronary unit for DHF. Methods: We conducted a retrospective study of consecutive patients admitted to 2 coronary care units between January 2010 and August 2020. Both indices and their respective predictive values were calculated. The cutoff point values with the best combination of sensitivity and specificity were defined using the ROC curve. Multivariate analysis was performed to identify independent predictors of in-hospital mortality. Results: Population: 1472 patients. Median age was 81 years, 50 had left ventricular ejection fraction <40% and 50% had a history of DHF. In-hospital mortality 6.2%. Youden's index identified SI ≥0.58 and age-adjusted SI ≥45.6 as predictors of mortality. On multivariate analysis including age, systolic blood pressure (SBP) <115 mmHg, blood urea nytrogen (BUN) >43 mg/ dL, creatinine level >2.75 mg/dL, hemoglobin (Hb) <10 g/dL and SI ≥0.58, only age, BUN >43 mg/dL and anemia remained as independent predictors of in-hospital mortality. On multivariate analysis, when age-adjusted SI ≥45.6 was analyzed with the other variables (but not with age), the independent predictors were age-adjusted SI ≥45.6 (OR 2.41; 95% CI, 1.37-4.2; p <0.01), BUN >43 mg/dL and anemia. Conclusion: A simple calculation as age-adjusted SI is highly useful to predict in-hospital mortality in patients hospitalized with DHF and provides additional information to the classic prognostic variables.

RESUMO

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.

RESUMO

RESUMEN Introducción: La insuficiencia cardíaca aguda es una problemática epidemiológica actual, en correlación con el incremento de la edad poblacional y la mayor sobrevida de los pacientes con enfermedades cardiovasculares. Objetivos: Evaluar el perfil clínico, las estrategias diagnósticas y terapéuticas y las complicaciones durante la internación y el seguimiento a 30 días del registro ARGEN-IC. Materiales y Métodos: Se efectuó un estudio prospectivo multicéntrico nacional, basado en los datos suministrados por 50 instituciones de salud (período: agosto 2018 a marzo 2019) referidos a pacientes con diagnóstico primario de insuficiencia cardíaca aguda, con un seguimiento de 12 meses. Resultados: Se incluyeron los datos de 909 pacientes aportados por 74 investigadores de 18 provincias. La media y el desvío estándar de la edad de los pacientes fue 72,2 (+-14) años y el 60,5% era de sexo masculino. Entre las características basales de esta cohorte, se destacaron las siguientes (prevalencia): diabetes (33%); IAM previo (17%); fibrilación auricular (31%); cobertura médica de prepagas (38%). Entre los factores desencadenantes, predominaron las causas desconocidas (28.5%), seguidas de las infecciosas (15,7%) y de transgresión alimentaria (13,5%). Se destaca la etiología isquémico-necrótica (26%), la presentación como congestión mixta (48%) y el grupo con fracción de eyección (Fey) deteriorada < o igual 40%. Las tasas de utilización de péptidos natriuréticos fueron cercanas al 50% y 25% al ingreso y egreso, respectivamente, y en el ecocardiograma se evaluó la funcion diastólica en un 77%, con alteracion significativa en el 46%. El 77,6% ingresó a unidad de cuidados críticos y la mediana de estadía hospitalaria global fue de 8 días, con una mortalidad global del 7,9%. El tratamiento farmacológico al egreso encontró en el grupo con Fey reducida: beta bloqueantes (BB), 78,7%; IECA, ARA II o ARNI, 70,9%; y antialdosterónicos, 56,3%. La derivación a rehabilitación cardiovascular abarcó el 17%. A 30 días se observó una tasa de reinternaciones del 16,7%; de mortalidad, del 5.5% (eventos combinados: 18%); y solamente el 47% había accedido a la consulta médica. Conclusiones: El registro ARGEN-IC abarca una población heterogénea, con una elevada edad media y alto número de comorbilidades. Las estrategias diagnósticas y terapéuticas demostraron estar sub-optimizada durante la hospitalización y los primeros 30 días, con escaso acceso al sistema de salud. La tasa global de eventos combinados intrahospitalarios y a 30 días continúa siendo elevada.


SUMMARY Introduction: Acute Heart Failure is currently an epidemiological problem, with a close correlation with the increase in the population age and the greater survival of patients with cardiovascular diseases. Objectives: Evaluate the clinical profile, the diagnostic and therapeutic strategies and the complications during hospitalization and the 12-month follow up of the ARGEN IC Registry. Materials and Methods: It's a prospective, multicenter, national Registry which included 50 health centers (August 2018-March 2019) and included patients with a confirmed diagnosis of acute heart failure with a 12-month follow-up. Results: A total of 909 patients were included, corresponding to 18 provinces and 73 active researchers. The mean age was 72.2 (SD 14) years, 60.5% of the patients were males. Baseline characteristics include a prevalence of diabetes of 33%, previous AMI 17%, and Atrial Fibrillation 31% and a predominant private security medical coverage (38%) Among the trigger factors of decompensation, 28.5% were associated with unknown causes, 15.7% infectious causes, and 13.5% with food transgression. The ischemic-necrotic etiology (26%), the presentation as mixed congestion (48%) and the impaired ejection fraction (EF) group stand out. 77.6% of the patients were admitted to the critical care unit, with a median overall hospital stay of 8 days and overall mortality of 7.9%. The pharmacological treatment at discharge, including the group with reduced EF: Beta Blockers (BB) 78.7%, ACEI, ARA II or ARNI 70.9% and anti aldosteronic 56.3% and the referral to cardiovascular rehabilitation in 17%. The 30-day follow-up showed a rehopitalization rate of 16.7%, mortality of 5.5% and combined events of 18%. Only 47% accessed the medical consultation. Conclusions: The ARGEN-IC Registry represents a heterogeneous population, with high middle ages and comorbidities. The diagnostic and therapeutic strategies are underutilized during hospitalization and in the first 30 days, with poor access to the health system. The overall combined rate of in-hospital events and at 30 days remains high.
