摘要：

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 less than or equal to0.90 predicted the presence of greater than or equal to3-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.
