[Mortality and morbidity after coronary bypass surgery in high-risk patients].
A total of 113 women and 912 men were submitted to coronary artery bypass surgery at Surgical Department A, Rikshospitalet between August 1982 and December 1986 and followed till January 1993. We found no difference in early mortality, recurrent angina pectoris or non-fatal myocardial infarction in diabetic patients compared to nondiabetic patients. However, total mortality was 1.87 times higher in the diabetic group. For patients with ejection fraction < or = 40%, early mortality was 10.2 times higher than for the reference group. For total mortality we found a practically linear relationship between increased mortality and falling ejection fraction values. We found no relationship between ejection fraction and recurrent angina and non-fatal myocardial infarction, neither did we find any difference in mortality and morbidity between women and men. Although a somewhat higher mortality and morbidity rate must be expected for high-risk patients, they seem to profit to the same extent from the favourable effects of coronary bypass surgery as other patients.
