Peripheral arterial disease (PAD) is associated with significant morbidity and mortality and is an important marker of systemic atherosclerosis. However, little is known about the associated risk factors for PAD in patients on maintenance hemodialysis (HD). We collected the basic data and possible risk factors associated with PAD for 277 patients on maintenance HD. Furthermore, we measured ankle-brachial blood pressure index (ABI) in these patients. PAD was defined as an ABI value less than 0.90. The prevalence of PAD in our HD center was 22.8% (61/268). Advanced age (P = 0.006), longer history of HD (P < 0.001), diabetes (P = 0.002) and presence of PAD symptoms (P < 0.001) were independent predictors of PAD. PAD patients with diabetes had shorter history of HD (P = 0.001). 2-vessel PAD had higher serum cholesterol in HD patients (≥ 200 vs < 200 mg/dL; Odds ratio, 12.12, 95% confidence interval, 2.199-67.79; P < 0.004).

Ankle-brachial index (ABI) is an important indicator of peripheral arterial disease (PAD) and PAD has a negative impact on quality of life (QOL). However, the correlation between ABI and QOL is unknown among chronic hemodialysis patients. Ankle-brachial index was measured, and WHOQOL-BRIEF (TW) questionnaire was completed. The association between ABI and QOL was analyzed using linear regression. A total of 54 chronic hemodialysis patients (mean age of 56.2 ± 14.6 years) were included. Ankle-brachial index was positively associated with QOL (r = .448, P = .001). The QOL scores were 3.1 ± 2.9 and 2.6 ± 0.4 for 37 patients with an ABI more than 0.9 and 17 patients with an ABI less than 0.9 or more than 1.3 (p < .001). In linear regression, only ABI was significantly associated with QOL scores with a β of .448 (95% CI: 0.443 to 1.55, P = .001). Ankle-brachial index is positively correlated to QOL among chronic hemodialysis patients.
