Why the study?
Does ankle-brachial index (ABI) accurately detect angiographic stenosis of peripheral arteries compared to digital subtraction angiography in high-risk cardiovascular patients?

298 consecutive Chinese high-risk cardiovascular patients (199 men, 99 women, mean age 64.9+/-11.3 years)

ABI 0.95 cutoff may aid stenosis detection in high-risk patients; leaves open prospective validation against angiography.
Does ankle-brachial index (ABI) accurately detect angiographic stenosis of peripheral arteries compared to digital subtraction angiography in high-risk cardiovascular patients?
An ABI cutoff of 0.95 provides high sensitivity (91%) and specificity (86%) for detecting hemodynamically significant peripheral artery disease in Chinese high-risk cardiovascular patients.
