Clinical predictors of coronary artery bypass graft surgery in patients hospitalized for Non-ST acute coronary syndrome - Buenos Aires I and ReSCAR22 registries.

Objectives: To identify predictors of coronary artery bypass graft surgery (CABG) requirement as a revascularization method in in real-world non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients. Materials and methods: . An individual pre-specified analysis of patients with NSTE-ACS was performed from two prospective Argentine registries between 2017 and 2022. We analyzed the difference in baseline characteristics between patients who required CABG and those who did not require this intervention. Then, a logistic regression analysis was performed to determine independent predictors in patients who received CABG as a method of revascularization. Results: A total of 1848 patients with a median age of 54.8 (interquartile range [IQR]: 53.7-56) years and an ejection fraction of 42.1% (IQR: 41.2-43.1) were included. A total of 233 patients required CABG (12.6%). Baseline characteristics between the two groups were similar, except in patients requiring CABG, who were younger (51.5 vs. 55.7 years; p=0.010), more frequently diabetic (38.2% vs. 25.7%; p=0.001) and male (90.1% vs. 73.7%; p=0.001). In addition, they had, to a lesser extent, previous cardiac surgery (2.1% vs. 11.2%; p=0.011). After multivariable analysis, the following were independently associated with CABG: age (Odds Ratio [OR]: 0.99, 95% confidence interval [CI]: 0.98-0.99; p=0.008), male sex (OR: 3.08, 95% CI: 1.87-5.1; p=0.001), history of previous CABG (OR: 0.14, 95% CI: 0.05-0.30; p=0.001) and diabetes (OR: 1.84, 95% CI: 1.31- 2.57; p=0.001). Conclusions: In this analysis of two NSTEACS registries, younger age, male sex, a diagnosis of diabetes and the absence of previous surgery were independent predictors of the requirement for inpatient CABG.

[Self-perception of smoking cessation skills among Cardiology residents in Argentina]. / Autopercepción de las habilidades para la cesación del tabaquismo entre los residentes de cardiología en Argentina.

Objective: To evaluate the self-perception of cardiology residents in Argentina regarding their abilities to help their patients stop smoking, as well as their opinions about their knowledge and skills in this area. Materials and methods: A cross-sectional study was carried out using secondary data from a study carried out in five Latin American countries and Spain, focusing on the information provided by cardiology residents in Argentina. Discrete variables were expressed as median and interquartile range, and categorical variables were expressed as percentages, and were analyzed using the chi-square test or Fisher's exact test, depending on the relative frequency of the expected values. Results: 447 residents participated; 87.5% routinely provided brief advice to quit smoking, and 11.6% used validated questionnaires to assess the degree of addiction. Furthermore, 32.1% stated that they prescribed pharmacological treatment, but 53.1% were only familiar with a single drug. When asked about their self-perception of getting their patients to stop smoking, the median response was 5 (scale from 1 to 10); only 13.7% responded with a score of 8 or more. Conclusions: The present study suggests that cardiology residents in Argentina recognize the importance of carrying out smoking cessation interventions, but a high proportion of them do not feel qualified to do so.

ABSTRACT Background Multiple mini-interviews (MMIs) serve as a model to evaluate non-cognitive skills in the admission process of health care professionals. Objective The aim of this study was to evaluate the feasibility, reliability and acceptability of the MMI model for the selection of residents and fellows in a cardiovascular center in the past 5 years. Methods We conducted an observational study including applicants to the cardiology residency program and to the fellowship in Nuclear Medicine and Cardiovascular Ultrasound in 2018, 2019 and 2022. Ten stations were developed to evaluate different non-cognitive domains. Reliability was assessed using G-coefficient. Applicants and interviewers were also surveyed to assess the acceptability of the MMI model and its feasibility in terms of the time required for the process. Results A total of 75 applicants participated in the MMIs. The G study showed reliability coefficients of 0.62 and 0.61 according to the design. Implementation was feasible; 92% of applicants gave positive reviews to the MMI model, and 90% of interviewers reported they had sufficient time to assess the participants and that the process was not an excessively exhausting. Conclusion MMIs are a novel method in our setting, demonstrating reliability and a high level of acceptability for evaluating non-cognitive skills in the selection process of applicants to the cardiology residency program and fellowships in a cardiovascular center.

Asociación entre niveles de empatía en médicos y satisfacción del paciente / Association between empathy levels in physicians and patient satisfaction

Resumen Introducción: Una buena relación médico-paciente es crucial para la práctica médica. Un elemento fundamen tal de la misma es la empatía del médico tratante, y esta puede ser cuantificada mediante una escala validada llamada Escala de Empatía de Jefferson. Métodos: En este estudio buscamos correlacionar los valores de empatía de los médicos del servicio con los resultados de las encuestas de satisfacción del pa ciente ambulatorio, medido mediante una herramienta llamada HCAPS. Resultados: Encontramos que los pacientes percibían un mayor trato respetuoso y que se les explicaba mejor sus opciones de tratamiento por parte de los médicos con mayores niveles de empatía. No hubo diferencias en los niveles de empatía de los médicos según su edad, sexo, o tiempo desde la obtención del título de especialista. Discusión: Los resultados validan a la empatía como una habilidad clave dentro de la relación médico-paciente.

Abstract Introduction: A good doctor-patient relationship is crucial to medical practice. A fundamental element of it is the empathy of the treating physician, and it can be quantified by means of a validated scale called the Jefferson Empathy Scale. Methods: In this study we sought to correlate the empathy values of our physicians with the results of outpatient satisfaction surveys, measured using a tool called HCAPS. Results: We found that patients perceived greater respectful treatment and had their treatment options better explained to them by physicians with higher lev els of empathy. There were no differences in physicians' empathy levels according to their age, gender, or time since qualifying as a specialist. Discussion: These results validate empathy as a key skill in the doctor-patient relationship.

Uso actual de la aspirina como agente antitrombótico: ¿droga vigente u obsoleta? / Present Use of Aspirin as an Antithrombotic Agent: Current or Outdated Drug?

RESUMEN El ácido acetilsalicílico, o aspirina, es una de las herramientas farmacológicas más usadas en el cuidado de los pacientes cardiovasculares. Durante años se utilizó ampliamente en prevención primaria y secundaria para disminuir el riesgo cardiovascular. En los últimos tiempos su uso ha sido cuestionado, con nuevos ensayos en diferentes escenarios dentro de la patología cardíaca, como la enfermedad vascular periférica, el accidente cerebrovascular, la prevención primaria en el contexto del tratamiento médico moderno, o en el paciente con un síndrome coronario agudo y necesidad concomitante de anticoagulación. A su vez, nuevos estudios cuestionan la necesidad de mantener la aspirina durante 12 meses junto a una tienopiridina luego de un síndrome coronario agudo, y proponen esquemas abreviados. En esta revisión, evaluamos la evidencia detrás de las indicaciones actuales del uso de aspirina en diferentes escenarios clínicos, y formulamos recomendaciones en cada uno de los casos.

ABSTRACT Acetylsalicylic acid, or aspirin, is one of pharmacological tools most widely used in the care of cardiovascular patients. For years, it has been widely used in primary and secondary prevention to reduce cardiovascular risk. Aspirin utilization has been questioned in recent times, with new trials in different scenarios of cardiovascular disease, such as peripheral vascular disease, stroke, primary prevention in the context of modern medical treatment, or in patients with acute coronary syndrome and concomitant need for anticoagulation. In turn, new studies question the need to maintain aspirin for 12 months together with a thienopyridine after an acute coronary syndrome, suggesting shorter regimens. In this review, we evaluate the evidence behind the current indications for aspirin use in different clinical scenarios and provide recommendations on a case-by-case basis.

Estimación del riesgo en cirugía cardíaca en el "mundo real": ArgenSCORE ajustado al centro / Cardiovascular Surgery Risk Assessment in the "Real World": ArgenSCORE Adjusted by Center

RESUMEN Introducción: El ArgenSCORE tiene una versión original (I) desarrollada en 1999 sobre una población con mortalidad del 8% y una versión II (recalibración del modelo en 2007) sobre una población con una mortalidad del 4%. Evaluamos en el registro CONAREC XVI la hipótesis de que el ArgenSCORE II podría estimar mejor el riesgo de mortalidad intrahospitalaria en los centros con baja mortalidad; en cambio, el ArgenSCORE I estimaría mejor la mortalidad en los centros con alta mortalidad. Material y métodos: Se analizaron 2548 pacientes de 44 centros del registro prospectivo y multicéntrico en cirugía cardíaca, CONAREC XVI. En cada centro se evaluó la mortalidad media observada (MO) y se calculó la mortalidad estimada media (ME) aplicando ambas versiones del ArgenSCORE. Se calculó la relación MO/ME de cada centro para los dos modelos y se evaluó si había diferencias significativas mediante el test Z. Resultados: La mortalidad intrahospitalaria del registro fue del 7,69%. El 75% de los centros (33/44) presentaban una mortalidad mayor del 6%. En centros con mortalidad menor del 6%, al aplicar el ArgenSCORE II, la relación MO/ME mostró valores cercanos a 1 y sin diferencias significativas. En centros con mortalidad mayor del 6%, el ArgenSCORE II subestima significativamente el riesgo. En cambio, cuando se aplica en estos centros el ArgenSCORE I, la relación MO/ME es cercana a 1 (sin diferencias significativas). Conclusiones: En centros con mortalidad menor del 6%, es recomendable utilizar el ArgenSCORE II-recalibrado; en centros con mortalidad mayor del 6%, tiene mejor desempeño el ArgenSCORE I-original.

ABSTRACT Background: The ArgenSCORE I was developed in 1999 on a population with 8% mortality. The ArgenSCORE II emerged after recalibrating the original model in 2007 on a validation population with 4% mortality. Using the CONAREC XVI registry, we evaluated the hypothesis that the ArgenSCORE II could better predict the risk of in-hospital mortality in centers with low mortality, whereas the ArgenSCORE I could better predict mortality in centers with high mortality. Methods: A total of 2548 patients from 44 centers of the prospective and multicenter cardiac surgery CONAREC XVI registry, were analyzed. Mean observed mortality (OM) and mean expected mortality (EM) were estimated applying both versions of the ArgenSCORE. The OM/EM ratio was calculated in each center for both models and the Z test was used to evaluate significant differences. Results: In-hospital mortality was 7.69% for the entire registry. In 75% of the centers (33/44) mortality was >6%. In centers with mortality <6%, the OM/EM ratio was close to 1 after applying the ArgenSCORE II, without significant differences. In centers with mortality >6%, the ArgenSCORE II significantly underestimated the risk. On the contrary, when the ArgenSCORE I was applied in these centers, the OM/EM ratio was close to 1, without significant differences. Conclusions: The recalibrated ArgenSCORE II is recommended in centers with mortality <6%, while in those with mortality >6% the original ArgenSCORE I has better performance.

Burnout y resiliencia en residentes de cardiología y cardiólogos realizando subespecialidades / Burnout syndrome in cardiology fellows and residents. The role of resilience

El síndrome de burnout es un estado de desgaste mental y físico muy prevalente en el ambiente médico. Está asociado a serios detrimentos físicos y emocionales de los profesionales de la salud, y se produce generalmente en un clima de trabajo adverso. Varios trabajos han demostrado que la resiliencia, definida como la capacidad de reponerse frente a las adversidades, puede ser un factor protector del síndrome de burnout. En este estudio se evaluaron los niveles de resiliencia por medio de un cuestionario validado en residentes de cardiología y cardiólogos realizando subespecialidades, y se relacionaron con los criterios de burnout. Se comprobó que un tercio de los encuestados presentaban niveles bajos de resiliencia y criterios positivos de burnout, y se encontró una asociación estadísticamente significativa entre ambas variables. Por su parte, la resiliencia se asoció negativamente con el cansancio y positivamente con la percepción de la realización personal. Es importante incorporar técnicas de detección de niveles bajos de resiliencia en residentes para intentar modificarlos y disminuir así el riesgo de burnout.

Burnout syndrome is a very prevalent condition of physical and mental wear in the medical profession. It is associated with serious physical and emotional consequences in health professionals, and is generally produced by an adverse working environment. Several research papers have proven that resilience, defined as the capacity to overcome adversity, can be a protective factor against burnout. In this study, levels of resilience were evaluated through a validated questionnaire in cardiology fellows and residents, and a relationship with burnout syndrome was established. One third of participants showed low resilience levels and a similar amount had positive criteria for burnout syndrome. A statistically significant association was found between these two conditions. Resilience was also negatively associated with tiredness, and positively with the perception of personal realization. Therefore, it is important to incorporate procedures for detecting low resilience levels in residents in order to attempt to improve them and thus diminish the risk of experiencing burnout.
