title: [Ischemic cadiopathy in patients undergoing chronic hemodialysis].
abstract: We report a retrospective study of patients on chronic hemodialysis in whom a diagnosis of ischemic heart disease had been established. We compared the findings on coronary cineangiography and the treatment (medical only, surgical revascularisation [CABG] and percutaneous transluminal coronary angioplasty [PTCA]) with the early and late evolution. From a population of 2,287 patients on chronic hemodialysis treatment during the 5 year period 1994-1999, 83 patients who underwent coronary cineangiography after starting dialysis were selected. Their mean age was 63 +/- 9.4 (39-80) and the mean time on hemodialysis was 6 years (6 months-19 years).
  
  
  RESULTS
  65 patients (78%) had severe coronary lesions, 40% of whom had three vessel disease. 14 patients had medical treatment only (group 1), 23 had CABG (group 2) and 28 PTCA (group 3). Mortality within 30 days of intervention was 13% in group 2 and 21.4% in group 3. Global survival at two years was 82% in group 2 and 69% in group 3. Survival without angina at 6 and 24 months were 69% and 46% in group 2 and 55% and 22% in group 3 respectively. Survival without acute myocardial infarction at 6 and 24 months was 95% and 95% in group 2 and 89% and 64% in group 3. Data analysis using Cox proportional risk model showed that PTCA posed a higher risk of angina and death than CABG.
  
  
  CONCLUSIONS
  Surgery yielded better early and later results than angioplasty even in those patients with severe coronary artery disease.
