The Prevalence of Peripheral Arterial Disease in a Racially Diverse Population

Abstract

Peripheral arterial disease is a prevalent illness in the primary care setting. Its prevalence varies by race and is higher in African Americans than in whites and Hispanics. Relative to the prevalence of PAD, the prevalence of intermittent claudication is low. Since measurement of the ankle-brachial index is not part of the routine clinic visit, many patients with PAD are not diagnosed unless they develop symptoms of intermittent claudication. Because of this, it is likely that many patients remain undiagnosed. Efforts are needed to improve PAD detection in the primary care setting.
