Abstract Left ventricular (LV) diastolic dysfunction (DD) and diastolic heart
failure (HF), that is symptomatic DD, are due to alterations of myocardial
diastolic properties. These alterations involve relaxation and/or filling and/or
distensibility. Arterial hypertension associated to LV concentric remodelling is
the main determinant of DD but several other cardiac diseases, including
myocardial i... hiện toàn bộ

AbstractBackgroundAbnormalities in right ventricular function are known to occur
in patients with pulmonary arterial hypertension.ObjectiveTest the hypothesis
that chronic elevation in pulmonary artery systolic pressure delays mechanical
activation of the right ventricle, termed dyssynchrony, and is associated with
both symptoms and right ventricular dysfunction.MethodsFifty-two patients (mean

Abstract Background Although echocardiography is commonly used to evaluate
cardiac function after MI, CMR may provide more accurate functional assessment
but has not been adequately compared with echo. The primary study objective was
to compare metrics of left ventricular volumes and global and regional function
determined by cardiac magnetic resonance (CMR) and echocardiography (echo) in
