Twelve years of coronary artery surgery in South Australia.
Twelve years' results of coronary artery bypass surgery in South Australia have been reviewed. The preoperative assessment parameters and operative profiles of 4001 patients who underwent isolated coronary artery grafting between 1970 and 1982 have been examined. In addition, all surviving patients received a follow-up questionnaire; only 48 patients have remained untraced. Survival curves for the patient group have been calculated and compared with those for the Australian population. The risk factors which influenced long-term survival have been identified. Surviving patients described their anginal symptoms as diminished in 93% of cases at the time of review. When recurrent angina was described, 58% of patients experienced it within 12 months of the operation. Postoperative activity was improved in 71% of patients; 8% described a deterioration. A second operation was performed in 2.1% of patients. This study provides a comprehensive review of the efficacy of coronary artery bypass surgery both in the short and in the medium term.
