Abstract:
Objective To explore the relationship between pulse pressure and aortic relative pulse wave velocity in the patients with hypertension by Doppler tissue imaging.Methods Velocities of abdominal aortic wall motion were measured in ninety one patients with essential hypertension.Electro mechanical time(EMT),pre ejection period (PEP) and the patient height(H) were measured and recorded respectively,and pulse wave time (PWT) was defined as EMT-PEP and relative pulse wave velocity (RPWV) as H/PWT.Results RPWV in the patients with pulse pressure ≥60 mm Hg ( 1 mm Hg = 0.133 kPa) was significantly greater than that of the patients with pulse pressure
