Ankle brachial index as a screening test in suspected coronary artery disease patients

ABSTRACT

Abstract The resting ankle- brachial index [ABI] is a non-invasive method to assess the patency of lower extremity arterial system and to screen for the presence of peripheral occlusive arterial disease. Diagnostic efficacy of ABI to predict atherosclerosis is well documented and reduction in index [< 0.9] is indicative of generalized atherosclerosis. Present study was planned to evaluate the role of ABI as a possible non- invasive marker for coronary atherosclerosis
