Peripheral vascular disease (PVD) is common among patients undergoing hemodialysis, but little is known regarding the risk factors for PVD in this population. Data from waves 1, 3, and 4 of the United States Renal Data System Dialysis Morbidity and Mortality Study were used to examine cross-sectional associations of a range of conventional cardiovascular risk factors and uremia- or dialysis-related variables with PVD. Univariate and multivariate logistic regression models were developed using wave 3 and 4 data. Odds ratios for the multivariate model derived using wave 3 and 4 data were then compared with those obtained with the wave 1 data set. For both data sets, PVD was positively associated with the duration of dialysis (vintage) and malnourished status and was negatively associated with serum albumin and parathyroid hormone levels and predialysis diastolic BP. Kt/V was negatively associated with PVD in waves 3 and 4 but not in wave 1. PVD was associated with increasing age, white (versus non-white) race, male gender, diabetes mellitus, coronary artery disease, cerebrovascular disease, smoking, and left ventricular hypertrophy, as for the general population, but not with hypertension or hyperlipidemia. In conclusion, PVD among hemodialysis patients is associated with both dialysis-specific variables and most conventional cardiovascular risk factors other than hypertension and hyperlipidemia. Future studies should prospectively examine the association of these variables identified in cross-sectional analyses with the de novo development of PVD in this population.
