Abstract:
Objective To investigate the relationship between the oxidized low-density lipoprotein(ox-LDL) in the blood from the coronary sinus and impaired endothelium-dependent vasodilation in patients with coronary artery disease(CHD).Methods Four groups of patients were subjected,including acute myocardial infarction group(AMI,n=22),unstable angina group(UA,n=29),and stable angina group(SA, n=25) and control group(n=20) who was first suspected as CHD and then verified with normal coronary angiograms.Blood form the coronary sinus was collected through cardiac cathetering and the ox-LDL level was measured by Sandwich ELISA method.Brachial arterial hyperemia-induced flow mediated dilation(FMD) and sublingual nitroglycerin(NTG) mediated vasodilation were measured by high resolution ultrasound.Results The blood level of ox-LDL in patients with CHD was markedly higher than those in control group(P
