RESUMO
Objective To study the occurrence of asymptomatic coronary artery endothelial lesions,and its relationship with coronary heart disease(CHD).Methods From June 2003 to September 2004,120 patients with old myocardial infarction(OMI)and stable angina pectoris(SAP)were enrolled in this study.The angioscopy of non-culprit vessels was successfully performed to detect the endothelial lesions including yellow plaque,plaque rupture and/or thrombosis.Meanwhile,the relationships between coronary artery endothelial lesions and hypertension,diabetes mellitus(DM)and low-density lipoprotein cholesterol(LDL-C)were examined.Results Detailed angioscopic findings were obtained in 80 of the 120 patients(66.67%)(in 155 non-culprit vessels).These lesions demonstrated a significantly higher occurrence in patients with hypertension,in patients with high level of LDL-C and in patients with DM than in patients without endothelial lesions(P
