We present a patient who was admitted to the emergency room due to unstable angina, with an initial electrocardiogram without signs of acute ischemia and a favorable clinical evolution. During hospitalization, she developed the Wellens electrocardiographic pattern, noted in the literature as an infrequent, poorly identified finding and with an ominous prognosis. This electrocardiographic pattern is described in precordial derivatives, suggesting a significant lesion of a principal epicardial artery; our patient had similar electrocardiographic alterations in the high lateral leads, in whom the coronary bifurcation lesion not previously described in this scenario was confirmed.

Presentamos el caso de una paciente que ingresó a emergencia por angina inestable, con electrocardiograma inicial sin signos de isquemia aguda y evolución clínica favorable. Durante la hospitalización desarrolló el patrón electrocardiográfico de Wellens, señalado en la literatura como un hallazgo infrecuente, poco identificado y de pronóstico ominoso. Este patrón electrocardiográfico se detalla en derivadas precordiales, sugiriendo una lesión significativa de una arteria epicárdica principal; la paciente tuvo alteraciones electrocardiográficas similares en las derivadas laterales altas, por lo que se confirmó el compromiso de bifurcación coronaria no descrita previamente en este escenario.

INTRODUCCIÓN. El Colegio Americano de Cardiología en el 2017 (ACC/AHA) definió Hipertensión arterial (HT) con un punto de corte menor a lo sugerido por la reciente guía de la Sociedad Europea de Cardiología (ESC) del 2018 (130/80 versis 140/90 mmH). Se ha reportado que el uso de un punto de corte más bajo aumentó la HT un 13.7%, de 31.9% a 45.6%, sin embargo el número de pacientes que requieren medicación sólo aumentó un 1.9%. El proyecto se justifica ante la ausencia de datos que midan el impacto de las nuevas recomendaciones de ACC/AHA y ESC sobre la frecuencia de HT en nuestra población. OBJETIVO PRINCIPAL: Determinar la frecuencia de hipertensión arterial de novo mediante las definiciones de la ESC (2018) y de la ACC/AHA (2017) en los pacientes que acuden al consultorio externo del Hospital Cayetano Heredia y cuantificar su variación según ambas definiciones. OBJETIVO...

We present a patient who was admitted to the emergency room due to unstable angina, with an initial electrocardiogram without signs of acute ischemia and a favorable clinical evolution. During hospitalization, she developed the Wellens electrocardiographic pattern, noted in the literature as an infrequent, poorly identified finding and with an ominous prognosis. This electrocardiographic pattern is described in precordial derivatives, suggesting a significant lesion of a principal epicardial artery; our patient had similar electrocardiographic alterations in the high lateral leads, in whom the coronary bifurcation lesion not previously described in this scenario was confirmed.

Objetivos: Determinar la frecuencia y describir las manifestaciones musculoesqueléticas (MME) en pacientes en hemodiálisis crónica (HDC). Material y métodos: Es una serie de casos. Se incluyeron 68 pacientes con edad ≥ 18 años, en HDC ≥ 6 meses, del Centro de Hemodiálisis de la Universidad Peruana Cayetano Heredia. Los datos demográficos, clínicos, tiempo en hemodiálisis, dosis de diálisis e ingesta proteica, y calcio, fósforo y fosfatasa alcalina séricos fueron obtenidos de las historias clínicas, en 38 pacientes se determinó PTH sérico y a 37 pacientes se les realizó densitometría ósea como parte de su evaluación. Resultados: La edad promedio fue 52,1 ± 22,1 años, el 52,9% fueron mayores de 60 años, el tiempo en HDC 21,6 ± 17 meses, la nefropatía diabética fue la etiología más frecuente. El 73,5% de los pacientes presentaron MME. La artrosis y la lumbalgi...

Cardiac amyloidosis (CA) is a form of cardiomyopathy characterized by the extracellular deposit of protein fibers in the myocardium, leading to the development of heart failure, arrhythmias, and electrical conduction system alterations. It is known that most cardiomyopathies have a close relationship with heart rhythm abnormalities, however, CA is specially related to different kinds of arrhythmias even in pre-diagnosis stages. Arrhythmias like atrial fibrillation are present in up to 70% of patients with CA associated with a high risk of cardioembolic complications independent of the risk stratification. Ventricular arrhythmias are frequent, but the use of implantable cardioverter defibrillator has not been demonstrated to improve survival. The Atrial-Ventricular node disease is also common, and is frequently associated with the implantation of a pacemaker, even in asymptomatic patients...

La amiloidosis cardíaca (AC) es una forma de cardiomiopatía caracterizada por el depósito extracelular de fibrillas de proteínas en el miocardio, lo que produce insuficiencia cardíaca, arritmias y alteraciones en el sistema de conducción eléctrica. La mayoría de las cardiomiopatías tienen una estrecha relación con las alteraciones del ritmo cardiaco, en especial la AC que está asociada a diferentes formas de arritmias, incluso en fases previas al diagnóstico. Arritmias como la fibrilación auricular se observan hasta en el 70% de los pacientes con AC asociadas a un especial riesgo de complicaciones cardioembólicas independiente de la estratificación de riesgo. Las arritmias ventriculares son frecuentes; sin embargo, la colocación del cardiodesfibrilador implantable no ha demostrado mejorar la sobrevida. La enfermedad del sistema de conducción eléctrica también es común...

The risk of sudden death in hypertrophic cardiomyopathy is related to the presence of ventricular arrhythmias in most cases. Finding the best schemes to assess the probability of arrhythmic complications will remain a challenge for modern Cardiology. Meanwhile, the multifactorial approach is the best strategy to avoid the unnecessary implantation of devices such as the implantable cardioverter defibrillator. Although the electrocardiogram remains an excellent diagnostic tool, even before echocardiographic expression, it does not have a clear role as a risk factor. However, the identification of associated arrhythmias such as preexcitation or long QT and variants of presentation as apical hypertrophic cardiomyopathy, allows identifying patients with high probability of sudden death. During the last few years, cardiac resonance and quantification of intramyocardial fibrosis (the basic mech...
