We sought to determine the role of an abnormal ankle-brachial index (ABI) in an African-American population with suspected coronary artery disease (CAD) referred for diagnostic coronary angiography. In this population, an ABI < or =0.90 predicted the presence of > or =3-vessel or left main CAD with a sensitivity of 85% and specificity of 77%. However, a normal ABI did not predict absence of 1- or 2-vessel CAD. These results suggest that in this population, the ABI can be used to increase the pretest probability of severe CAD.
我们试图确定异常踝臂指数（ABI）在因疑似冠状动脉疾病（CAD）而接受诊断性冠状动脉造影的非裔美国人中的作用。在该人群中，ABI≤0.90预测存在≥3支血管病变或左主干CAD的敏感性为85%，特异性为77%。然而，正常的ABI并不能预测不存在单支或双支血管病变。这些结果表明，在该人群中，ABI可用于提高严重CAD的预检概率。
