ARAGAO, José Aderval et al. Prevalence of peripheral occlusive arterial disease in patients with chronic renal failure. J. vasc. bras. [online]. 2009, vol.8, n.4, pp.301-306. ISSN 1677-5449. http://dx.doi.org/10.1590/S1677-54492009000400004.
Background: Peripheral occlusive arterial disease has been found to be a sensitive marker of systemic atherosclerosis and a predictor of other cardiovascular diseases. In spite of the high prevalence of the cardiovascular diseases, there are few studies about peripheral occlusive arterial disease in patients with chronic renal failure under hemodialysis treatment. Objective: To determine the prevalence of peripheral occlusive arterial disease in patients with chronic renal failure under hemodialysis treatment at a center of excellence in the State of Sergipe, Brazil. Methods: A cross-sectional study was conducted from June to November 2008 at a center of excellence for the treatment of patients with chronic renal failure. Those patients with the ankle-brachial index (ABI) ≤ 0.9 were diagnosed as having peripheral occlusive arterial disease. Results: From a population of 239 individuals with chronic renal failure, 201 were evaluated. Of that, 28 (14%) had peripheral arterial insufficiency with ABI ≤ 0.9. Their age ranged from 24 to 82 years (mean age = 52 years). Hypertension and dyslipidemia were the more frequent risk factors. Among the patients with peripheral occlusive arterial disease, 89% had dyslipidemia; 71% had high blood pressure; and 29% had coronary diseases. Conclusion: The prevalence of peripheral occlusive arterial disease in patients with chronic renal failure was 14%.
