Non‐Hispanic Black and Hispanic patients have worse outcomes than White patients within similar stages of peripheral artery disease

Journal of the American Heart Association Dec 26, 2021

Kalbaugh CA, Witrick B, Sivaraj LB, et al. - Among patients undergoing infrainguinal revascularization for chronic limb‐threatening ischemia and claudication, worse limb outcomes were experienced by Black and Hispanic patients vs White patients, even with similar disease severity at presentation.

  • Using the Vascular Quality Initiative data (2011–2018), a total of 88,599 patients (age, 69 years; 37% women) undergoing elective revascularization for claudication or chronic limb‐threatening ischemia were analyzed for 1‐year risk of major adverse limb events (MALEs), major amputation, and death.

  • The calculated 1‐year risk of MALE (major amputation and death) was 12.8%, 16.5%, and 17.2% in 67,651 White patients, 15,442 Blacks, and 5506 Hispanic patients, respectively.

  • For poor limb outcomes, an increased hazard was noted in Black (MALE: 1.17; amputation: 1.52) and Hispanic (MALE: 1.22; amputation: 1.45) patients, vs White patients.

  • However, Black and Hispanic patients were found to have a hazard of death of 0.85 and 0.71 times the hazard in White ones, respectively.

  • Black and Hispanic patients exhibited worse limb outcomes across subcohorts of claudication and chronic limb‐threatening ischemia.
