ABSTRACT Objective: Treatment of subclinical hypothyroidism (ScH), especially the mild form of ScH, is controversial because thyroid hormones influence cardiac function. We investigate left ventricular systolic and diastolic function in ScH and evaluate the effect of 5-month levothyroxine treatment. Su...
Fundamentos: O conhecimento do ângulo de fase e seu uso como determinante prognóstico em pacientes com
insuficiência cardíaca ainda é escasso. Objetivo: Avaliar a relação entre indicadores antropométricos, função cardíaca e integridade celular em pacientes com insuficiência c...
Abstract Penetrating heart injuries present high mortality rates. Increasing rates of urban violence have contributed to a significant rise in the number of heart injuries by firearm projectiles. Such injuries are associated with the highest mortality rates among penetrating cardiac injuries and may invo...
Abstract Background: Ventricular premature contractions (VPCs) may trigger lethal ventricular arrhythmias in patients with structural heart disease. However, this role of VPCs in healthy people remains controversial once that not enough clinical trials are available. Recently, some myocardial repolariza...
ABSTRACT CONTEXT: Obstruction of the right ventricular outflow tract due to metastatic disease is rare. Clinical recognition of cardiac metastatic tumors is rare and continues to present a diagnostic and therapeutic challenge. CASE REPORT: We present the case of a patient who had severe respiratory ins...
O eletrocardiograma corresponde ao registro gráfico da atividade elétrica cardíaca. As ondas que o compõem são obtidas por meio de cabos-eletrodos posicionados de maneira convencional na superfície corpórea, e, por essa razão, apresentam características tanto de duração como de morfologia bem ...
