[Late results of aortocoronary shunting in ischemic heart disease patients in relation to the severity of the coronary lesion and degree of myocardial revascularization].

Long-term results of aortocoronary shunting are reviewed in 219 coronary patients with reference to the severity of coronary arterial damage and myocardial revascularization. Functional class of angina pectoris declined 2.5-fold postoperatively and was 1.6 +/- 0.14 at long-term follow-up. The success rate reached 74%. Survival rate was 87.3%, including hospital mortality, and long-term survival was 92.1%. Acute coronary insufficiency was the principal cause of compromised success and survival rates. The operation was particularly effective in patients with first- or second-degree total coronary arterial lesion and true complete myocardial revascularization.
