In order to determine how renal transplantation modifies in hospital and long-term outcome after coronary angioplasty, we compared dialysis and renal transplant patients with control patients without renal failure. Seventy-five consecutive dialysis patients (group D) and 37 renal transplant patients (group T) undergoing coronary angioplasty, were compared with two control groups (groups control D and control T, respectively) matched 1:1 with groups D and T for clinical and angiographic characteristics. The mean follow-up was 50 months. The rate of angiographic success was high and comparable in the four groups (P = 0.7). Renal transplant patients were younger than dialysis nontransplant patients (P = 0.004). The risk of 4-year cardiac death and nonfatal myocardial infarction was higher in dialysis compared to control dialysis patients (OR 2.6, 95% CI 1.35–5.01, P = 0.004), in transplant patients compared to control transplant patients (OR 9.93, 95% CI 1.17–84.04, P = 0.03), and there was a trend toward a higher risk in dialysis than in renal transplant patients (OR 1.6, 95% CI 0.8–3.19, P = 0.08). The risk of 4-year mortality was higher in dialysis patients than in the other three groups (31% in group D versus 19% in group T, 13% in group control D, and 0% in group control T, P 〈 0.001). After adjusting for age, diabetes, and multivessel disease, long-term mortality risk was similar in dialysis and renal transplant patients. On multivariate analysis, renal function (P = 0.002), age (P = 0.005), and tobacco consumption (P = 0.005) were independently associated with 4-year cardiac death. In patients with end-stage renal disease who undergo coronary angioplasty, renal transplantation was not independently associated with a lower long-term mortality compared to dialysis treatment. Both dialysis and renal transplant patients show lower survival rates compared to matched control patients.
