Is hepatojugular reflux a good predictor of heart failure with preserved ejection fraction?

SUMMARY Hypertension may occur with left ventricular (LV) diastolic dysfunction, and the consequence may be symptoms and signs of heart failure (HF). Hepatojugular reflux (HJR), described as a sign of regurgitation of the tricuspid valve, may reflect structural and functional changes of the LV in the hyp...

Intra-Atrial Dyssynchrony Using Cardiac Magnetic Resonance to Quantify Tissue Remodeling in Patients with Atrial Fibrillation

Arq. bras. cardiol; 112 (4), 2019
Abstract Background: Recent studies suggest that left atrial (LA) late gadolinium enhancement (LGE) can quantify the underlying tissue remodeling that harbors atrial fibrillation (AF). However, quantification of LA-LGE requires labor-intensive magnetic resonance imaging acquisition and postprocessing a...
