Apneia obstrutiva do sono e doença cardiovascular

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...

Efficacy, Safety, and Performance of Isolated Left vs. Right Ventricular Pacing in Patients with Bradyarrhythmias: A Randomized Controlled Trial

Arq. bras. cardiol; 112 (4), 2019
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...

Predictores de hospitalización prolongada en pacientes con insuficiencia cardiaca aguda

Rev. colomb. cardiol; 26 (2), 2019
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...

Echocardiographic Correlation between Right Ventricular Function and Left Atrial Volume

Arq. bras. cardiol; 112 (3), 2019
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...

Evaluation of the global longitudinal strain and segmental strain of the right ventricle with two-dimensional speckle-tracking echocardiography with elevation of the legs

Arch. cardiol. Méx; 89 (1), 2019
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...

Correlation between myocardial velocity measured using tissue doppler imaging in the left ventricular lead-implanted segment and response to cardiac resynchronization therapy

Clinics; 74 (), 2019
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 ...
