Burden of Peripheral Artery Disease on Mortality and Incident Cardiovascular Events: The Multi-Ethnic Study of Atherosclerosis.

Using one value for an individual's ankle brachial index (ABI) may inadequately quantify the risk for mortality and cardiovascular (CVD) events. Using data from the Multi-Ethnic Study of Atherosclerosis (2000-2015), 6,527 racial/ethnically diverse adults (62+/-10 years) free of known CVD had ABI assessment of their bilateral dorsalis pedis/posterior tibial arteries (4-vessels total) and followed for total mortality, incident CVD events/mortality. Individuals were classified into 0, 1, 2, 3 or 4 -vessel PAD (ABI
