ABSTRACT
Objective To investigate the endothelial function and atherosclerosis in patients with coronary artery disease (CAD).Methods Two-dimensional echocardiography (2-DE) was used tomeasure changes in brachial artery inner diameter as parameter of endothelium-dependant and endothelium-nondependant vascular diastolic function and pathologic characters of carotid atherosclerosis in 90 elderly CAD patients and 30 controls.Results Endothelium-dependant vascular diastolic function and endothelium-non dependant diastolic function were significantly decreased in CAD group as compared with control group [(9.08±2.28)% and (6.14±2.21)% vs.(15.58±2.20)%, P<0.01].The carotid intima-media thickness and plaque score were significantly increased in CAD group as compared with control group.Conclusions There are correlations of endothelium dysfunction and carotid atherosclerosis are relatied to with coronary atherosclerosis.
