Amyloidosis is a multisystem disease caused by infiltration of misfolded proteins; cardiac involvement determines its prognosis. There are several types of precursor proteins capable of causing the disease; however, only two affect the heart, clonal immunoglobulin light chains (AL) and tetrameric transthyretin (TTR) protein. It is an underdiagnosed disease and, in late stages, it has a poor prognosis. We present the case of an older adult patient with progressive cardiac and extracardiac manifestations, as well as laboratory and echocardiographic criteria that brought us closer to the diagnosis of cardiac amyloidosis and also allowed us to assess the prognosis. The patient had a torpid evolution with a fatal outcome. The pathological anatomy studies allowed us to confirm our diagnostic presumption.

Electrocardiographic findings in ST-segment elevation acute myocardial infarction do not always evolve in a typical manner, with concomitant changes such as early repolarization that can cause diagnostic confusion. We present the case of a patient with typical chest pain and an atypical electrocardiogram, in which the presence of early repolarization in the inferior leads caused subtle changes in the precordial leads to be overlooked, leading to an error in the initial diagnosis but not in the treatment.

Introducción: La resucitación cardiopulmonar es un conjunto de maniobras que deben realizarse en forma sistemática y simultánea, para salvar vidas. El que las realice, debe tener un sólido conocimiento teórico-práctico de la técnica a usar. Objetivo: Determinar la diferencia en el conocimiento teórico-práctico de Reanimación Cardio Pulmonar según el tipo de intervención educativa en estudiantes de medicina del Perú. Métodos: Estudio de intervención de tipo educativo, realizado en estudiantes de dos universidades peruanas. La variable principal fue medir el cambio del nivel de conocimiento teórico-práctico según el tipo de instrucción (Teórico, teórico – practico o Practico), medida con un cuestionario previamente validado1. Se utilizó las pruebas estadísticas de chi cuadrado para las variables categóricas y ANOVA para el análisis de variables numéricas versus...
