NONCARDIAC SURGERY IN PATIENTS WITH ISCHEMIC HEART DISEASE

From January 1983 to December 1988, 4679 patients with operated under general anesthesia in our institute: 161 patients involved suspected ischemic heart disease (IHD patients) by history or electrocardiogram. Eight of 161 patients (5.0%) experienced fatal or life-threatening cardiac complications. On the other hand, only two non･IHD patients (0.03%) experienced complications. IHD patients had a significantly higher incidence of complications compared with non-IHD patients. Forty-five IHD patients had not undergone coronary cineangiogram (CAG) before noncardiac operations and six of them (13.8%) experienced complications. They had a significantly higher incidence of complications compared with other IHD-patients who had received CAG. Fifty-five IHD patients who had already been treated by coronary bypass grafting (CABG) or by percutaneous transluminal angioplasty experienced only one complication. We conclude that CAG should be more actively performed for IHD patients because prior CABG or PTCA is suspected to decrease cardiac complications in IHD patients, However, IHD patients must be managed as carefully as possible.
