Lifelong Limb Preservation: An Update on Peripheral Artery Disease By George Hipp, MD, RPVI with Alabama PVD Center in Clinical

Over 10 million people in the Unites States and over 200 million worldwide have peripheral arterial disease (PAD).1 Critical limb ischemia (CLI), defined as ischemic rest pain or tissue loss resulting from arterial insufficiency, affects approximately 1% of the adult population, or 10% of patients with PAD.2 Further increasing the impact of CLI is the poor prognosis it carries. Major amputation occurs in 33-67% of patients with ischemic tissue loss at 4 years.3,4 Mortality at 2 years in CLI patients is as high as 40%, and appears to be even higher in those with tissue loss. The vast majority of these deaths are due to cardiac events, cardiovascular disease, and cancer, rather than PAD.4,5

Peripheral Vascular Disease By J. Hudson Segrest, M.D. with Heart South Cardiovascular Group in Clinical

Peripheral artery disease is a widespread and vastly underdiagnosed disease, affecting nearly 12 million Americans, mostly those over the age of 50, though the incidence increases with age. The most common symptom of peripheral arterial disease is claudication, which is pain, fatigue or aching in the legs when someone attempts to walk. This is due to the poor blood flow to the muscles in the legs. Beyond simply the discomfort in the legs, we know that having peripheral vascular disease makes one much more likely to have poor cardiovascular outcomes. Among patients with symptomatic peripheral arterial disease, more than 10% will have a stroke, heart attack, or die from a cardiovascular cause within two years. And when we look longer term, the statistics are even more sobering. For patients with symptomatic peripheral arterial disease, their mortality rate is 25% at 5 years and 50% at 10 years. When looking at patients with critical limb ischemia (those who have pain at rest or wounds on their feet), the numbers are even worse: they have a mortality rate of 50% at 5 years and 90% at 10 years.
