A apneia obstrutiva do sono (AOS) é uma condição prevalente, que tem sido associada com diversas consequências cardiovasculares, sendo a hipertensão arterial a mais bem descrita. Entretanto, doença arterial coronariana, arritmias cardíacas, acidente vascular
cerebral e risco aumentado de mortalid...
Abstract Background: Considering the potential deleterious effects of right ventricular (RV) pacing, the hypothesis of this study is that isolated left ventricular (LV) pacing through the coronary sinus is safe and may provide better clinical and echocardiographic benefits to patients with bradyarrhyth...
Resumen Introducción: la insuficiencia cardiaca aguda es la principal causa de hospitalización en adultos mayores de 65 años. La duración de las hospitalizaciones es un determinante del incremento en los costos por la atención hospitalaria. Objetivo: describir el perfil clínico de los pacientes...
Abstract Background: Few reports exist on the relationship of the left ventricular diastolic dysfunction (LVDD) with its most important features including enlargement of the left atrium and left ventricular hypertrophy (LVH), and with the right ventricular (RV) function. Objective: To determine the cor...
Abstract Introduction: Speckle-tracking echocardiography has shown its usefulness in the evaluation of the right ventricle (RV) in healthy subjects and in pulmonary hypertension. It is unknown whether this technique could be sensitive to assess healthy RV with increases in preload. Methods: Consecutive...
OBJECTIVES: This study investigated whether tissue Doppler imaging parameters, especially the peak systolic velocity of the left ventricular lead-implanted segment (Ss), affect cardiac resynchronization therapy response. METHODS: In this case-control study, 110 enrolled patients were divided into cases ...
