Surgical neuromodulation therapies are still considered a last resort when standard therapies have failed for patients with progressive heart failure (HF). Although a number of experimental studies have provided robust evidence of its effectiveness, the lack of strong clinical evidence discourages practi...
Abstract INTRODUCTION: The minute ventilation-carbon dioxide production relationship (VE/VCO2 slope) is among the main prognostic factors of Chagas cardiomyopathy whose determinants remain unknown. METHODS: Seventy-eight patients with Chagas cardiomyopathy were evaluated using clinical assessment, car...
Fundamento: A quimioterapia para o câncer de mama está associada a complicações cardiovasculares graves, como a insuficiência cardíaca. A fração de ejeção do ventrículo esquerdo é o principal parâmetro para avaliar a função sistólica nessas pacientes. Todavia, a ocorrência de disfunção...
Fundamentos: Miocardiopatia não compactada (MCNC) caracteriza-se por hipertrabeculações e recessos profundos no ventrículo esquerdo, com apresentação clínica heterogênea, desde pacientes assintomáticos a insuficiência cardíaca (IC), eventos tromboembólicos arritmias com risco de morte súbita...
Fundamento: A ecocardiografia transtorácica (ETT) pode desempenhar um papel crucial na avaliação das manifestações cardíacas da COVID-19. Objetivo: Nosso objetivo foi relatar a prevalência das principais anormalidades ecocardiográficas em pacientes hospitalizados com COVID-19. Métodos: Realizou-...
BACKGROUND: Chronic heart failure (CHF) is a global health problem. Increased sympathetic outflow, cardiac arrhythmogenesis and irregular breathing patterns have all been associated with poor outcomes in CHF. Several studies showed that activation of the renin-angiotensin system (RAS) play a key role in ...
BACKGROUND: Heart failure (HF) is the leading cause of death in western countries. Cardiac dysfunction is accompanied by skeletal alterations resulting in muscle weakness and fatigue. Exercise is an accepted interventional approach correcting cardiac and skeletal dysfunction, thereby improving mortality,...
OBJECTIVES: We aimed to compare the effects of home-and center-based exercise training programs on functional capacity, inspiratory muscle strength, daily physical activity level, and quality of life (QoL) in patients with chronic heart failure (CHF) over a 12-week period. METHODS: This study included 2...
