踝臂指数与不稳定型心绞痛病人短期进展为急性心肌梗死的关系

摘要

Objective To examine the relation between ankle-brachial pressure index ( ABI) and the prognosis of unstable angina (UA) patients. Methods ABI was measured in 192 UA patients. The correlation between ABI and myocardial infarction was to be observed. Results The ABI was in negative relationship with severity of coronary artery stenosis. The AUC(95% CI) of ABI was 0. 710 (0. 603 ～ 0. 839). Conclusions ABI is effective to predict the occurrence of myocardial infarction in UA.%目的 观察踝臂指数(ABI)与不稳定型心绞痛(UA)病人短期进展为急性心肌梗死(AMI)的关系.方法 选取192例不稳定型心绞痛患者,观察ABI与心肌梗死事件的关系.结果 ABI与冠状动脉的严重程度成负相关,ABI越低,UA严重程度越高.ABI的曲线下面积为0.710,95%CI为0.603~0.839.结论 ABI是预测UA发生心肌梗死一个比较有效的指标.
