Aortocoronary bypass in stable angina pectoris.
The authors describe the main principles of indication, contraindication and operative technique in the surgical treatment of stable angina pectoris. Special attention is given to the estimation of the operative risk. The number of bypass grafts per patient in the 291 patients operated on in 1980-1982 averaged 2.7. In-hospital mortality was 1.4%, ranging from zero mortality in patients with ejection fraction greater than or equal to 40%, 2.5% in patients with EF = 30-40% and to 13.3% in patients with EF under 30%. A new peri- or postoperative ischaemic episode occurred in 2.4% of patients.
