103例踝臂指数和冠状动脉狭窄相关性的回顾分析

Retrospective analysis on correlation of ankle brachial index and coronary disease

目的初步探讨踝臂指数(ABI)与冠状动脉狭窄的相关性。方法回顾分析103例在第三军医大学大坪医院心内科测定踝臂指数并接受选择性冠状动脉造影患者,根据冠状动脉造影结果将冠状动脉狭窄分为正常、轻度狭窄(每支狭窄程度均小于或等于50%)、单支病变、双支病变及三支病变(每支狭窄程度均大于或等于50%)五个等级。将踝臂指数与诊断冠状动脉狭窄的金标准冠状动脉造影相比,分析踝臂指数与冠状动脉狭窄的相关性。结果随着冠状动脉狭窄程度加重,踝臂指数值逐渐降低。结论ABI与冠状动脉狭窄具有良好的相关性。

Objective To analyse the correlation of ankle brachial index and coronary disease. Methods We investigated 103 patients accepted ankle brachial index assessment and coronary angiography in the cardiovascular department of Daping Hospital. Coronary occlusion was divided into five grades according to coronary angiography： normal, slight occlusion（occlusion degree of each branch ≤50%）, single branch occlusion, double branches occlusion, three branches occlusion（occlusion degree of each branch 50 %）. The results were compared with ankle brachial index to analyze the correlation of ankle brachial index and coronary disease. Results The decreased ankle brachial index was accompanied with increased coronary occlusion. Conclusion Ankle brachial index is well related to coronary heart disease.
