THE SAGE GROUP Releases New Estimates for the United States Prevalence and Incidence of Peripheral Artery Disease (PAD) and Critical Limb Ischemia (CLI)

BEAUFORT, S.C.–(BUSINESS WIRE)–$CLI #CLI–According to THE SAGE GROUP, in 2015 almost 20 million U.S. citizens
suffered from PAD. Reflecting the aging population this number is
projected to increase to 25 million by 2030.

Critical limb ischemia (CLI), the most severe and deadly form of the
disease, currently afflicts 2 to 3.4 million of those with PAD. By 2030
the U.S. prevalence of CLI is forecast to exceed 4 million.

Commenting on the difference between THE SAGE GROUP’S PAD estimates and
the commonly quoted numbers of 8-12 million, Mary L. Yost, President
stated, “Our PAD numbers have always been considerably higher and these
revised estimates increase the gap even more. We are often asked why?”
she said.

Ms. Yost explained, “Our estimates are dynamic, increasing with the
aging population and the growing prevalence of diabetes. Based on the
‘Diabetes Method’ our 1995 PAD estimate was 11 million, which agrees
with the 8-12 million range. However, since then the population has aged
and become considerably more diabetic, especially in two key age groups;
45-64 and 65 and older.”

Age and diabetes are two significant risk factors for PAD and CLI. The
U.S. is experiencing an epidemic of diabetes with the fastest increases
occurring in senior citizens. According to the 2011-2012 National Health
and Nutrition Examination Survey, 33% of the elderly have diabetes.

“In contrast, our original PAD and CLI estimates were based on a much
lower prevalence of diabetes in the elderly. Our new PAD and CLI
estimates reflect the higher prevalence of diabetes. Nothing else has
changed,” Yost observed.

About the Report: Critical Limb Ischemia Volume I United States
Epidemiology, 2016 Supplement

The 2016 supplement includes updated 2015-2030 prevalence data for PAD
and CLI, as well as newly published incidence estimates. All U.S.
epidemiology studies published since 2010 are reviewed and compared.
