【摘要】 目的探讨踝臂指数(ABI)对冠状动脉病变狭窄程度的预测价值。方法对108例行冠状动脉造影或介入治疗的患者,进行ABI测量、血液生化检查、病史采集及冠状动脉造影;主要观察ABI与冠状动脉严重程度的相关性。结果按照冠状动脉病变最大狭窄程度分组,冠状动脉病变程度间ABI有显著性差异(P<0.05);冠状动脉造影多支病变组与冠造正常组、单支病变组、双支病变组ABI比较,有显著性差异(P<0.05);回归分析提示ABI≤0.90是预测冠状动脉严重病变的可靠指标。结论ABI≤0.9对冠状动脉动脉病变的严重程度有预测价值;ABI与冠状动脉病变最大狭窄程度呈显著相关性,可作为对冠心病患者危险分层评估的一项可靠指标。更多还原

【Abstract】 Objective To investigate the correlation between ankle-brachial index and predict the extent of coronary artery disease stenochoria.Methods Patients who had taken the coronary angiography or percutaneous coronary intervention were enrolled.All the patients underwent ABI measurement and blood biochemistry examination,history-taking,coronary arteriongraphy.The correlation between ABI and the extent of coronary atherosclerosis lesions was to be observed.Results According to the different group of largest narrow degree of coronary artery,there were significant differences in severity of coronary heart disease.There were significant differences between severe coronary artery disease(CAD)(3-vessel disease plus left main disease) and non-severe CAD(normal vessel,1-vessel disease,2vessel disease).Regression analysis indicated that ABI ≤0.90 could predict the presence of 3-vessel CAD.Conclusion ABI≤0.90 can predict the presence of 3-vessel CAD.Ankle-brachial index and the extent of coronary artery disease stenochoria has significant dependability.更多还原
