Abstract］ Objective To assess the endothelium-dependent relaxation in patients with essential hypertension or hypertension smokers by color Doppler flow imaging.Methods With intermittent ultrasound imaging and power Doppler imaging,we measured endothelium-dependent relaxing function in 72 subjects 24 of whom with essential hypertension,24 of whom with both hypertension and smokingand the others as normal control.We measured the diameter of the superficial femoral and brachial arteries at rest,during reactive hyperaemia,re-test and after sublingual glyceryl trinitrate for evaluating the endothelium-independent dilatation in subjects.The level of plasma NO,ET,PGI2,and TXB2 were determined.
