摘要
目的观察踝臂指数对不稳定型心绞痛患者预后的预测价值。方法选取79例不稳定型心绞痛患者和37例正常对照组,观察ABI与心肌梗死事件的关系。结果ABI与UA严重程度成负相关,ABI越低,UA严重程度越高。正常组、低危组、中危组、高危组之间比较,有统计学意义(P<0.05)。ABI的曲线下面积为0.722,95%CI为0.602-0.841。结论ABI是预测UA发生心肌梗死一个比较有效的指标。
Objective To study aimed to examine the relation between ankle-brachial pressure index (ABI) and the prognosis of unstable angina (UA) patients. Methods ABI was measured in 79 UA patients, and 37 normal controls. The correlation between ABI and myocardial infarction was to be observed. Results The ABI was in negative relationship with the extent of UA. There were significantly statistical differences in ABI between high risk, moderate risk, low risk and normal control ( P 〈 0. 05 ). The AUC ( 95 % CI ) of ABI is 0. 722 (0. 602-0. 841 ). Conclusion ABI is effective to predict the occurrence of myocardial infarction in UA.
