Risk Factors

Who is at risk for PAD?

	Age – The incidence of PAD increases with age, and affects approximately 20% of the U.S. population over 70. Due to an aging population, the estimated number of people with PAD is expected to grow to over 17 million in 2010 and over 22 million in 2020.1
	Smoking – Smokers have three times the rate of PAD as non-smokers and are diagnosed on average 10 years earlier.2
	Diabetes – In 2002, there were 18 million U.S. adults with diabetes, with approximately 1.3 million new cases of diabetes diagnosed each year.3 The prevalence of PAD is 20% higher in the diabetic population. It is estimated that over 23% of patients with diabetes between ages 55 – 74 have PAD.4
	Coronary artery disease – An estimated 40% of patients with CAD have PAD.5

Additional risk factors include hypertension, high cholesterol, obesity and family history.
