Short- and long-term outcomes after percutaneous transluminal coronary angioplasty in chronic hemodialysis patients.
The aim of this study was to obtain data on the outcomes of chronic hemodialysis patients who underwent percutaneous transluminal coronary angioplasty (PTCA). A retrospective chart analysis identified 31 such patients between August 1992 and October 1996. The mean follow-up period was 12.4 +/- 11.7 months. Angiographic success was achieved in 39 of 41 (95.1%) stenoses attempted. There were three in-hospital deaths. Clinical success was achieved in 28 of 31 patients (90%). Two of the 28 survivors were lost to follow-up. Recurrent angina developed within 6 months in 14 of 26 patients (53.8%). Eleven and 17 of the 26 patients (42.3% and 65.4%) died within 6 and 14 months, respectively, after the PTCA procedure. Ten of the 17 deaths (58.8%) were due to cardiovascular events. Our study suggests that PTCA is technically feasible with high angiographic success rate in chronic hemodialysis patients. In-hospital mortality rate and rate of recurrent angina are high. Long-term prognosis is poor.
