Thousands in Phoenix May Be Affected by Peripheral Artery Disease (PAD)

PAD is the biggest disease that most people have never heard about. Up to a staggering 18 million Americans1 suffer from PAD, a potentially life-threatening disease. As many as 68,500 people in the Phoenix-Mesa-Scottsdale metro area have PAD,2,3 a condition where plaque builds up along blood vessel walls, narrowing the arteries and reducing blood flow to the legs and feet.

There are more than 160,000 PAD-related amputations in the U.S. each year, so when left untreated, PAD can lead to amputation.4 And the rate of amputation for African-American and Hispanic-Americans with PAD is higher than for white Americans.

• African-Americans are twice as likely to be amputated as a result of advanced PAD as Caucasians.5
• Hispanics receive an amputation for PAD at a rate 50 percent higher than Caucasians.5

A new study published in the Journal of Racial and Ethnic Health Disparities, “Explaining Racial Disparities in Amputation Rates for the Treatment of Peripheral Artery Disease (PAD) using Decomposition Methods,” concludes that compared to Caucasians, African-Americans and Hispanic-Americans have less access to limb-saving PAD procedures because they are being admitted to the hospital for treatment when they are sicker and more likely on an emergency basis.5

Some studies suggest that African-Americans may not feel the symptoms as early as Caucasians, therefore they do not seek treatment as early.6 A simple screening test, called an ankle-brachial index (ABI), in which the blood pressure in a person’s ankle is compared to the blood pressure in the arm, can be used to identify PAD in people who are at risk.

A national campaign, Take A Stand Against Amputation, is seeking to raise awareness of PAD and to encourage people with symptoms to talk to a doctor about the disease. The campaign website, www.StandAgainstAmputation.com, contains useful information about the disease, its risk factors, symptoms and treatment options. The campaign is gaining visibility in the Phoenix area.
