Coronary artery surgery in this historical cohort had an overall mortality of 4.2% and a perioperative infarction rate of 10.7%, with modern myocardial protection principles helping to lower these rates.
These historical rates should not guide current practice; leaves open the impact of modern myocardial protection on contemporary outcomes.
This paper assesses the results in 543 patients undergoing coronary artery surgery between 1969 and March, 1976. Indications included angina, acute infarction and ventricular arrhythmia, and there were some angina-free patients. Surgical techniques were constantly reviewed and frequently changed. The mortality in all groups was 4.2%. The mortality in chronic stable angina (424 cases) was 3%, but as from January, 1975, it has been 2%. The perioperative infarction rate in all groups was 10.7%, and this condition was the most significant cause of perioperative mortality. Modern principles of myocardial protection during surgery have helped to lower mortality and morbidity rates.
