Aspirin plus verapamil relieves angina and perfusion abnormalities in patients with coronary microvascular dysfunction and Chagas disease: a pilot non-randomized study

Abstract INTRODUCTION: Most patients with chronic cardiomyopathy of Chagas disease (CCCD) harbor a secondary cause of coronary microvascular dysfunction (CMD), for which there is no evidence-based therapy. We evaluated the impact of verapamil plus aspirin on symptoms and perfusion abnormalities in patie...

Home-based training program in patients with chronic heart failure and reduced ejection fraction: a randomized pilot study

Clinics; 76 (), 2021
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...

Clinical and echocardiographic predictors of left ventricular remodeling following anterior acute myocardial infarction

Clinics; 76 (), 2021
OBJECTIVES: Coronary artery disease is the primary cause of death and is responsible for a high number of hospitalizations worldwide. Ventricular remodeling is associated with worse prognosis following ST-segment elevation myocardial infarction (STEMI) and is a risk factor for ventricular dysfunction and...

Positive heparin/pf4 antibodies and high mortality rate: a retrospective case-series analysis

Abstract Introduction: Heparin-induced thrombocytopenia (HIT) is a potentially lethal complication of unfractionated or low-molecular weight heparin therapy. We aimed to determine the incidence and mortality rate of patients with positive heparin/platelet factor 4 (PF4) antibodies, which is a rapid dete...

Quantificação Semiautomática da Fração de Ejeção e Volumes do Ventrículo Esquerdo ao Ecocardiograma Bidimensional: Comparação com o Ecocardiograma Tridimensional Automático

ABC., imagem cardiovasc; 33 (4), 2020
Fundamento: A fração de ejeção do ventrículo esquerdo é um dos parâmetros ecocardiográficos mais utilizados na prática clínica. Sua estimativa pelo método bidimensional manual (método de Simpson) tem reprodutibilidade e acurácia limitadas, e métodos semiautomáticos têm sido propostos. Tor...

Takotsubo Invertido Versus Miocardite Aguda: a Importância da Ressonância Cardíaca para Diagnóstico Diferencial

ABC., imagem cardiovasc; 33 (4), 2020

Frontal plane QRS-T angle may be a predictor for post-coronary artery bypass graft surgery atrial fibrillation

SUMMARY BACKGROUND: New-onset postoperative atrial fibrillation (POAF) is the most common arrhythmia following coronary artery bypass graft surgery (CABG) and is associated with prolonged hospitalization, stroke, and mortality. The frontal plane QRS-T [f(QRS-T)] angle, which is defined as the angle betw...

Efectos clínicos de la corrección del valor de la fracción de expulsión del ventrículo izquierdo en pacientes con insuficiencia valvular mitral

Arch. cardiol. Méx; 90 (4), 2020
Resumen Introducción y objetivos: La insuficiencia valvular mitral provoca el vaciado simultáneo hacia la aorta y la aurícula izquierda durante la sístole ventricular, lo que produce una disminución del volumen hacia la circulación sistémica. En este estudio se busca obtener un dato preciso del p...

Alterações Precoces nas Interleucinas Circulantes e no Risco Inflamatório Residual após Infarto Agudo do Miocárdio

Arq. bras. cardiol; 115 (6), 2020
Resumo Fundamento Pacientes com infarto agudo do miocárdio podem apresentar uma grande área infartada e disfunção ventricular mesmo com trombólise e revascularização precoces. Objetivo Investigar o comportamento das citocinas circulantes em pacientes com infarto agudo do miocárdio com suprade...

Estudo Comparativo da Doença Coronariana Microvascular Causada por Doença de Chagas e por Outras Etiologias

Arq. bras. cardiol; 115 (6), 2020
Resumo Fundamento A doença de Chagas (DC) constitui uma causa potencial negligenciada de doença microvascular coronariana (DMC). Objetivos Comparar pacientes com DMC relacionada à DC (DMC-DC) com pacientes com DMC ligada a outras etiologias (DMC-OE). Métodos De 1292 pacientes estáveis, encamin...
