目的观察新疆维吾尔族患者踝臂指数与冠状动脉狭窄程度的相关性,评价踝臂指数对新疆维吾尔族患者冠状动脉狭窄程度的预测价值。方法对114例连续入选冠状动脉造影患者进行踝臂指数测量、病史采集及血液生化检查。结果踝臂指数与Gensini评分呈显著负相关(r=-0.6941,P<0.001)。各组间的踝臂指数值差异有显著性(P=0.000);评价踝臂指数对三支或左主干病变预测价值的操作者工作特征曲线下面积为0.8219,面积的标准误Se=0.0415,(u=7.7518,P=0.0000);踝臂指数≤0.9作为界限值预测三支或左主干病变具有相对较高的特异度(91.76%)和敏感度(41.38%)。结论新疆维吾尔族患者踝臂指数与冠状动脉狭窄严重程度显著负相关,踝臂指数≤0.90对预测冠状动脉三支或左主干病变具有较高的特异度和敏感度。
Objective To observe the correlation between the ankle-brachial index and the degree of coronary artery stenosis in Xinjiang Uigur patients, and to evaluate the predictive value of ankle-brachial index on the degree of coronary artery stenosis in Uigur patients in Xinjiang. Methods A total of 114 patients undergoing coronary angiography were measured ankle brachial index, medical history and blood biochemical tests. Results There was a significant negative correlation between ankle brachial index and Gensini score (r = -0.6941, P <0.001). (P = 0.000). The area under the operating characteristic curve for evaluating the predictive value of ankle-brachial index for three or left main stem lesions was 0.8219, the standard error of area was Se = 0.0415, (u = 7.7518, P = 0.0000). Ankle-brachial index ≤0.9 as the threshold value predicted that the three branches or left main trunk lesions had relatively high specificity (91.76%) and sensitivity (41.38%). Conclusion There is a significant negative correlation between the ankle-brachial index and the severity of coronary artery stenosis in Xinjiang Uyghur. The ankle-brachial index ≤0.90 has high specificity and sensitivity for predicting the three branches of the coronary artery or the left main lesion.
