However, because the ABI calculation requires measurement of the ankle and the brachial systolic pressures, previous prospective studies relating the ABI to subsequent cardiovascular events and mortality can separately analyze the independent predictive value of the systolic ankle and brachial blood pressures for cardiovascular events and mortality. For example, a meta-analysis relating the ABI to cardiovascular events and mortality included ...References1.
