RESUMEN
Background: Practice is essential in clinical training and can be carried out with simulations. The medical school of the University of Chile performs Objective Structured Clinical Examinations (OSCE) using standardized simulated patients for interns. Aim: To report the experience with OSCE in an environment with a high number of students. Material and Methods: Four hundred sixty-two students, participated in three OSCEs during 2016 and 2017, during their internal medicine clerkship. Each OSCE consisted of five scenarios of ambulatory care patients with prevalent medical conditions. Every student had to perform history taking, physical examination and deliver a diagnostic hypothesis, and a plan for management and counseling. Simulated patients provided feedback. To assess validity and reliability, in an argument-based model, planning and activity development were declared. The results were evaluated according to students' and organization variables, internal consistency, interobserver and theoretical concordance tests. Results: No significant bias was found by demographic features or evaluation moment. Internal consistency was good (Cronbach 0.8). Simulated patient evaluators had a high correlation with medical evaluators (r = 0.7). There was a low correlation between OSCE results and theoretical tests. Conclusions: OSCE's continuously assess competences during internal medicine clerkship in an environment with a high number of students.

Introducción: La cardiopatía isquémica es la principal causa de muerte en Cuba. Laangioplastia coronaria con stent es una excelente opción terapéutica, pero la reeste-nosis ensombrece su pronóstico y es mucho más frecuente con el uso de stents con-vencionales. Objetivo: Caracterizar clínica y angiográficamente la reestenosis del stent coronario convencional. Método: Se realizó un estudio descriptivo y transversal en los 59 pacientes con diagnóstico de reestenosis del stent coronario convencional confirmado por angiografía en la Unidad de Cardiología Intervencionista del Cardiocentro Ernesto Che Guevarade Villa Clara, Cuba, durante el período febrero 2010 abril 2012. Las variables analizadas fueron edad, sexo, factores de riesgo coronario, historia previa de angina oinfarto, vaso afectado, tipo de reestenosis y de lesión tratada, diámetro del vaso ylongitud de la lesión. Resultados: Predominaron los pacientes del sexo masculino (76,3 por ciento), con edadescomprendidas entre 60-69 años (40,7 por ciento). Los factores de riesgo más frecuentes fueron la hipertensión arterial (76,3 por ciento), el hábito de fumar (37,3 por ciento) y la diabetes mellitus tipo II (33,9 por ciento). El vaso más afectado fue la descendente anterior (59,3 por ciento), los diámetros arteriales eran predominantemente ≤ 2,5 mm (54,2 por ciento) y la longitud de las lesiones > 20 mm (66,1 por ciento). Las lesiones tipo B (52,5 por ciento) y la reestenosis focal (57,6 por ciento) fueron más frecuentes(AU)
