What factors influence the results of coronary artery bypass grafting in aged patients?

Abstract

Aim. Early and late results were studied in order to improve the indication for coronary artery bypass grafting (CABG) and to enhance results. Methods. A total of 1 973 patients aged 70 years and older who had undergone isolated CABG were studied. Elective operations (EL) were performed in 1 716 patients and 257 patients underwent urgent or emergency operations (UR/EM). Patients were divided into two groups; 104 patients aged 80 years and older (Oct. Group) and 1 869 patients of septuagenarians (Sept. Group). There were no differences between the groups in the number of diseased vessels. Results. Total operative mortality rates in the Oct. and the Sept. groups were 7% and 4%, respectively. T..
