Effects of left ventricular geometric patterns on cardiac function and carotid artery structure in elderly patients with essential hypertension / 上海第二医科大学学报

ABSTRACT

Objective To observe the changes of cardiac function and carotid artery structure in elderly hypertensive patients with different left ventricular geometric patterns. Methods Seventy-eight elderly patients with essential hypertension were divided into 4 groups according to left ventricular geometric patterns by ultrasonography normal ventricular geometry group(n=34),concentric remodeling group(n=18),concentric hypertrophy group(n=11)and eccentric hypertrophy group(n=15).The 24-h ambulatory blood pressure,left ventricular function,carotid artery intima-media thickness(IMT),hemodynamic parameters and incidence of plaque were measured and compared among groups.Results Patients in concentric hypertrophy group had higher 24-h average systolic blood pressure in comparison with those in normal ventricular geometry group and concentric remodeling group(P
