We compared clinical outcomes following percutaneous transluminal coronary angioplasty (PTCA) for 77 chronic renal failure (CRF) (dialysis and nondialysis) patients and a control group matched for history of myocardial revascularization, specific revascularization procedure, gender, age, diabetes, number of native vessels diseased, number of vessels dilated, and the specific vessel(s) dilated. CRF patients had a higher incidence of peripheral vascular disease, hypertension, and more complex PTCA target lesion types than controls: 5% vs. 16% Type A, 12% vs. 28% Type B1, 44% vs. 41% Type B2, 39% vs. 15% Type C (p < 0.001). The primary success rate for PTCA in CRF patients and controls was 89% and 97% (p < 0.05). Survival analysis 24 months following PTCA showed a lower composite cardiac event-free survival (angiographic restenosis, myocardial infarction, coronary artery bypass surgery, and cardiac death) for those with CRF than controls, 54% vs. 69% (p = 0.002). Over the study period, 26 CRF patients died (11 from cardiac causes) compared to only 3 control patients (one from a cardiac cause); p < 0.001 for all cause and p < 0.003 for cardiac mortality. We also compared PTCA results between two categories of CRF patients. The first consisted of 49 end-stage renal disease (ESRD) patients on dialysis and the second included 28 patients not on dialysis (13 with creatinine > 2. 0 mg/dL and 15 with ESRD post-renal transplant). Both subgroups had similar coronary anatomy, including PTCA, target lesion type, and acute and long-term outcomes. In conclusion, we observed acceptable primary success and complication rates for PTCA in CRF patients compared with controls matched for comorbid features despite more complex target lesion morphology. Poorer long-term outcomes, however, were apparent for those with CRF regardless of dialysis dependence and likely relate to more extensive atherosclerosis and complex target coronary lesions at index PTCA as well as other features related to CRF.
