We hypothesized that atherosclerotic renovascular disease (ARVD) might account for a growing proportion of end-stage renal disease in the United States because of shared risk factors and the aging of the population. We tested this hypothesis through an evaluation of 146 973 older patients starting dialysis therapy in the United States between 1996 and 2001.
