🎯
Objective & Hypothesis:Objective: We aimed to evaluate left atrium (LA) phasic functions and relation with N-terminal pro-B- type natriuretic peptide (NT-proBNP) levels and symptomatic states of the patients with hypertrophic cardiomyopathy (HCM).Methods: Left atrial volume was calculated at end-systole (Vmax), end-diastole and pre-atrial contraction by echocardiography in 75 patients with HCM and 75 control subjects.
📊
Key Findings & Data:NT-proBNP levels were measured.Results: Left atrial active emptying volume (LAAEV) positively correlated with Vmax (r=0.343, p=0.003) up to a point, but then reached a plateau with larger LA volumes in HCM group.

Abstract

Objective: We aimed to evaluate left atrium (LA) phasic functions and relation with N-terminal pro-B- type natriuretic peptide (NT-proBNP) levels and symptomatic states of the patients with hypertrophic cardiomyopathy (HCM).Methods: Left atrial volume was calculated at end-systole (Vmax), end-diastole and pre-atrial contraction by echocardiography in 75 patients with HCM and 75 control subjects. Left atrial ejection fraction (LAEF), expansion index (LAEI), active emptying volume index (LAAEVI) and fraction (LAAEFr), passive emptying volume index (LAPEVI) and fraction (LAPEFr) were calculated. NT-proBNP levels were measured.Results: Left atrial active emptying volume (LAAEV) positively correlated with Vmax (r=0.343, p=0.003) up to a point, but then reached a plateau with larger LA volumes in HCM group. The LAAEFr was the only variable which was similiar between asymptomatic patients and controls, but was significantly decreased in symptomatic patients (p
