Abstract:
Objective To better understand the age related changes of cardiac structure and function and their relationship with gender, body weight and blood pressure. Methods M mode, 2 dimensional, and Doppler echocardiographic studies were performed on 306 healthy intellectuals, including 165 males and 141 females, ranging in age from 30 to 85 years. Results Parameters in both male and female including the ratio of peak E wave to peak A wave velocity(E/A), the ratio of the right ventricular peak E wave to peak A wave velocity(E/Ar), the amplitude of aortic wall (Aao) and the angle between septum and the root of aorta (?) were all decreased with the aging significantly( P
