Peripheral artery disease is a common vascular disorder. In contrast to coronary and cerebral artery disease, peripheral arterial disease remains an underappreciated condition that despite being serious and extremely prevalent is rarely diagnosed and even less frequently treated. Early diagnosis of peripheral artery disease and individual assessment of risk factors are important in preventing further cardiovascular complications. The ankle-brachial index is a simple, reliable tool for diagnosing peripheral artery disease. Many studies underscore the importance of using the ankle-brachial index to identify persons with peripheral artery disease, since peripheral artery disease is frequently undiagnosed or asymptomatic. Measurement of the ankle-brachial index is simple enough to be performed in any doctor’s office, and it is one of the most reliable indices of peripheral artery disease.
