摘要
目的:观察踝臂指数测量值(ABI)对国人冠状动脉狭窄程度及冠心病病人的预测价值。方法:选取112例行冠状动脉造影的患者进行ABI测量、病史收集、生化检查和统计学处理,观察ABI、临床指标与冠状动脉造影结果的相关性。并随访13.4±2.3月,观察ABI与心血管事件(心源性死亡、非致死性心肌梗死、不稳定性心绞痛、冠状动脉旁路移植术)的相关性。结果:冠状动脉造影严重病变组和非严重病变级间ABI有显著差异;ABI降低与ABI正常组间心血管事件发生率先有显著差异。结论:ABI<0.9对冠状动脉严重病变(三支和左主干病变)及冠心病患者的预后有预测价值。
Objective：This study aimed to examine the relation between ABI and the extent of eoronary atherosclerosis, the extracoronary atherosclerosis lesions, and the prognosis of parient referred for elective coronary angiography. Methods： 112 routine patients underwent coronary angiography , and ABI evaluation; subjects were followed up for 13.4±2.3months. Results：ABI was related to the extent of coronary artery disease as measured by number of coronary arteries diseased. In the follow - up study ABI 〈 0.90 was a univariate predictor of cardiovascular events （ cardiac drath, nonfatal myocardial infarction, unstable angina） and revascularization procedures. Conclusion： ABI is a simple index related to the extent of atherosclerosis in coronary and noncoronary arterial beds, reflecting generalized atherosclerosis. ABI could be useful in assessing the risk for cardiovascular events in patients with coronary artery disease.
