Abstract:
Objective To investigate the effect of left ventricular geometric patterns on left atrial performance in patients with hypertension by acoustic quantification (AQ) technique. Methods Sixty eight hypertensive patients and 20 control subjects were studied. According to left ventricular mass index (LVMI) and relative wall thickness, normal left ventricular geometry, concentric remolding, concentric hypertrophy and eccentric hypertrophy were grouped in patients with hypertension. Left atrial ejection fraction (LAEF), conduit volume (CV) and reservoir volume (RV) were measured with AQ technique. Results Compared with control subjects, RV was increased more significantly in patients with normal left ventricular geometry and concentric remolding; RV and LAEF were increased, and CV was decreased significantly in patients with concentric hypertrophy; LAEF and CV were decreased, and RV was increased significantly in patients with eccentric hypertrophy. Conclusions The redistribution of left atrial reservoir function, booster pump function and conduit function is an important compensatory mechanism that facilitates left ventricular filling in hypertensive patients with different left ventricular geometric patterns. Left atrial dysfunction occurs in patients with eccentric hypertrophy.
