More than a quarter of a billion people in the world have peripheral artery disease (PAD), with poorer countries disproportionately affected, the first global analysis of the disease found.
The global prevalence of PAD increased by 24% from 2000 to 2010, from 164 million to 202 million, according to Gerald Fowkes, BSc, MBChB, from the Centre for Population Health Sciences at the University of Edinburgh in Scotland, and colleagues.
The AHA endorsed the most commonly used threshold of 0.90 or less for peripheral arterial disease detection, although it noted that the American Diabetes Association has proposed minor modifications of the criterion for diabetes patients based on observational study findings.

A proximal location significantly increases the risk of poor outcomes in peripheral arterial disease (PAD), independent of risk factors and comorbidities, a review of records on 400 patients showed.
Proximal (aortoiliac) involvement tripled the risk of cardiovascular events compared with distal disease. The findings contrast with evidence of poorer limb prognosis in patients with distal PAD, according to an article published online in the Journal of the American College of Cardiology.
