Aim. Cardiac surgery carries a high risk in hemodialysis patients and has been questioned for its results; the purpose of this study is to focus on the short and long term results in our institution.
Methods. We retrospectively analyzed the data from 124 hemodialysis patients who underwent cardiac surgery in our unit between January 1980 and December 1998; 14.5% were diabetic; 46% had isolated coronary artery disease (group 1); 29.8% had valvular disease alone (group 2); 14.5% valve and coronary disease (group 3) and 9.6% miscellaneous disease at highest risk (group 4). We analyzed the relationship between several variables (age, sex, hypertension, diabetes, previous myocardial infarction, type of disease, preoperative ejection fraction) and operative mortality (30 days) and late survival.
Results. The overall operative mortality was 16.9%. The only risk factor was the type of cardiac disease: operative mortality was higher in groups 3 and 4 combined than in groups 1 and 2 combined (30% versus 12.7%, p=0.07). Ninety-nine patients were followed until January 2002. Late survival rate was 46.6±5% at 6 years for all patients, it was significantly better in groups 1 and 2 combined than in groups 3 and 4 combined. The only risk factor for late mortality was arterial hypertension. Fifty-seven patients are still alive, 46 in groups 1 and 2, 11 in groups 3 and 4. Progression of coronary lesions occurred in 6 patients and valvular lesions in 3 patients. The remainder are doing well.
Conclusion. Cardiac surgery seems to be justified by the severity of the lesions. Its actual results can perhaps, be improved by earlier detection of cardiac disease and better prevention of myocardial hypertrophy and cardiac calcifications.
