Tempo de aceleração na via de saída do ventrículo direito: correlação com a função diastólica do ventrículo esquerdo, sexo e idade

ABC., imagem cardiovasc; 35 (1), 2022
Fundamento: O tempo de aceleração na artéria pulmonar (TAP) pode ser utilizado para avaliação da hipertensão pulmonar na análise da função diastólica do ventrículo esquerdo. Objetivo: Avaliar se existe correlação entre o valor do tempo de aceleração na artéria pulmonar e parâmetros da fu...

Echocardiographic Assessment of Ventricular Function in Young Patients with Asthma

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Despite significant advances in understanding the pathophysiology and management of asthma, some of systemic effects of asthma are still not well defined. Objectives: To compare heart function, baseline physical activity level, and functional exercise capacity in young patients w...

Natriuretic Peptide and Clinical Evaluation in the Diagnosis of Heart Failure Hemodynamic Profile: Comparison with Tissue Doppler Echocardiography

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Physical examination and B-type natriuretic peptide (BNP) have been used to estimate hemodynamics and tailor therapy of acute decompensated heart failure (ADHF) patients. However, correlation between these parameters and left ventricular filling pressures is controversial. Objectiv...

Prognostic Value of Coronary Flow Reserve Obtained on Dobutamine Stress Echocardiography and its Correlation with Target Heart Rate

Arq. bras. cardiol; 108 (5), 2017
Abstract Background: Normal coronary flow velocity reserve (CFVR) (≥ 2) obtained in the left anterior descending coronary artery (LAD) from transthoracic echocardiography is associated with a good prognosis, but there is no study correlating CFVR with submaximal target heart rate (HR). Objective:...

Doppler velocimetry in fetal rats exposed to enoxaparin and unfractionated heparin (UFH) during pregnancy

Acta cir. bras; 32 (5), 2017
Abstract Purpose: To evaluate the effects of enoxaparin and unfractionated heparin (UFH) administered in prophylactic and therapeutic doses on fetal vessels in healthy pregnant Wistar rats, according to Doppler velocimetry measurements. Methods: Fifty animals were assigned to one of five groups: contro...

Assessment of the left ventricular function in normotensive prediabetics: a tissue Doppler echocardiography study

ABSTRACT Objective Several studies have shown that left ventricular (LV) dysfunction is increased in individuals with diabetes. However, there are scarce data about LV function in prediabetics. This study assessed the early changes in LV diastolic and systolic myocardial function in normotensive predia...
