We investigated the association between ankle brachial index (ABI) and coronary heart disease (CHD) severity in elderly Egyptians using different measures. We conducted a case–control study from November 2010 to June 2012 including 200 male and female patients with ischemia ≥60 years who were divided into 100 cases and 100 controls according to ABI and redivided according to age. They underwent coronary angiography followed by ABI measurement using a hand-held Doppler. The CHD severity was estimated using the SYNTAX and Jeopardy scores and number of diseased vessels, which increased significantly in patients with peripheral artery disease (P < .001) for all. All 3 measures had strong negative correlation with ABI (P ≤ .001 for Jeopardy, <.001 for SYNTAX scores, and .004 for number of diseased vessels) and were correlated with each other. We concluded that ABI can reflect CHD severity in elderly Egyptians.
