Latin-American guidelines of recommendations at discharge from an acute coronary syndrome.

The diagnostic criteria, treatments at the time of admission, and drugs used in patients with acute coronary syndrome are well defined in countless guidelines. However, there is uncertainty about the measures to recommend during patient discharge planning. This document brings together the most recent evidence and the standardized and optimal treatment for patients at the time of discharge from hospitalization for an acute coronary syndrome, for comprehensive and safe care in the patient's transition between care from the acute event to the outpatient care, with the aim of optimizing the recovery of viable myocardium, guaranteeing the most appropriate secondary prevention, reducing the risk of a new coronary event and mortality, as well as the adequate reintegration of patients into daily life.

Los criterios diagnósticos, los tratamientos en el momento de la admisión y los fármacos utilizados en pacientes con síndrome coronario agudo están bien definidos en innumerables guías. Sin embargo, existe incertidumbre acerca de las medidas para recomendar durante la planificación del egreso de los pacientes. Este documento reúne las evidencias más recientes y el tratamiento estandarizado y óptimo para los pacientes al momento del egreso de una hospitalización por un síndrome coronario agudo, para un cuidado integral y seguro en la transición del paciente entre la atención del evento agudo y el cuidado ambulatorio, con el objetivo de optimizar la recuperación de miocardio viable, garantizar la prevención secundaria más adecuada, reducir el riesgo de un nuevo evento coronario y la mortalidad, así como la adecuada reinserción de los pacientes en la vida cotidiana.

[Characteristics of cardiologist training in Latin America: a survey of the Interamerican Society of Cardiology]. / Características de la formación de los cardiólogos en América Latina: una encuesta de la Sociedad Interamericana de Cardiología.

Objectives: Describe the characteristics of the different cardiology medical residencies in Latin America. Method: Cross-sectional study that aims to evaluate the characteristics of cardiology residencies in Spanish-speaking countries of Latin America, through self-administered electronic surveys. Results: Three hundred seven residents of 147 residences were surveyed. Mean age was 31 years and 63% were male. Ninety eight percent carry out their training in the capital city. The average total training time is 4.8 years. Forty four percent complete their residency in internal medicine prior to starting cardiology, and 10% have no prior training. In cardiology training is 3 years in most countries. Fifty four percent present academic activities every day and 16% only once or less, consisting of theoretical classes (93%), clinical cases (85%), bibliographic workshops (69%), and writing scientific papers (68%). Supervision is carried out by the chief resident (45%), resident coordinator (44%), resident instructor (27%) or the department head (54%), while 2.6% do not present supervision. The main rotations were echocardiography (99%), hemodynamics (96%), coronary unit (93%), and electrophysiology (92%). Residents highlighted the need to improve academic activities (23%) and scientific production (12%). Conclusions: There are important differences in the academic and practical training between the residences of the different countries of America.

Objetivos: Describir las características de las diferentes residencias médicas de cardiología de Latinoamérica. Método: Estudio de corte transversal que tiene como objetivo evaluar las características de las residencias de cardiología en países hispanohablantes de América Latina, mediante encuestas electrónicas autoadministradas. Resultados: Se encuestó a 307 residentes de 147 residencias. La mediana de edad fue 31 años y el 63% era de sexo masculino. El 98% realiza su formación en la ciudad capital. El tiempo de formación total promedio es de 4.8 años. El 44% realiza la residencia completa en medicina interna previo al inicio de cardiología, y el 10% no tiene formación previa. En cardiología la formación es de tres años en la mayoría de los países. El 54% presenta actividades académicas todos los días y el 16% solo una vez o menos, consistente en clases teóricas (93%), casos clínicos (85%), ateneos bibliográficos (69%) y redacción de trabajos científicos (68%). La supervisión es realizada por el jefe de residentes (45%), coordinador de residentes (44%), instructor de residentes (27%) o el jefe de servicio (54%), mientras que el 2.6% no presenta supervisión. Las rotaciones principales fueron ecocardiografía (99%), hemodinamia (96%), unidad coronaria (93%) y electrofisiología (92%). El 23% resaltó la necesidad de mejorar las actividades académicas y 12% la producción científica. Conclusiones: Existen importantes diferencias en la formación académica y práctica entre las residencias de los diferentes países de América.

Hemodynamically significant prosthesis-patient mismatch can be predicted and is associated with early prosthetic valve dysfunction in aortic bioprosthesis.

OBJECTIVES: To evaluate the accuracy of predicted prosthesis-patient mismatch (PPM) regarding actual PPM measured postoperatively. To assess the association between PPM and prosthetic valve dysfunction. METHODS: Retrospective cohort study including adult patients after aortic valve replacement surgery with a biological prosthesis. Predicted PPM status was determined using mean reference effective orifice area indexed to total body surface (iEOA), without considering reference standard deviations. Postoperative PPM status was determined by measuring iEOA within the first 60 postoperative days. Prosthetic valve dysfunction was defined as thrombosis, pannus, valve degeneration, and/or disruption. RESULTS: 205 patients were enrolled between January 2003 and June 2017: predicted PPM was absent in 52 patients (25.4%), moderate in 137 patients (66.8%), and severe in 16 patients (7.8%). After surgery, the actual postoperative iEOA was measured: 53 (25.9%) did not have PPM, 73 had moderate PPM (35.6%), and 79 had severe PPM (38.5%). Predicted PPM identified the presence of hemodynamically significant actual postoperative PPM (OR = 2.56; 95%CI 1.30-5.05; P = .006), though not its degree of severity. Prosthetic valve dysfunction was more frequent among patients with hemodynamically significant PPM (53.9% vs. 11.3%; P < .001), compared to those without PPM. The association between PPM and prosthetic valve dysfunction was maintained after adjusting for gender, age, and ever-smoking (OR = 9.03; P < .001). The incidence of thrombosis or pannus was also nonsignificantly higher in patients with moderate or severe PPM. CONCLUSIONS: Predicted PPM identifies the presence, possibly not the severity, of actual postoperative PPM. Moderate or severe PPM is associated with prosthetic valve dysfunction. Actual postoperative prosthesis-patient mismatch measured within 60 postoperative days showed a distinctive hemodynamic profile and presented a stronger association with prosthetic valve dysfunction than predicted prosthesis-patient mismatch. A. Echocardiographic follow-up in patients according to the actual postoperative PPM measured within 60 postoperative days. B. Prediction of prosthetic valve dysfunction based on preoperative predicted PPM or on actual postoperative PPM within 60 postoperative days. PPM: prosthesis-patient mismatch. OR: Odds ratio.
