What is the incidence of perioperative myocardial infarction in patients undergoing CABG for chronic stable angina, and what are the most appropriate diagnostic techniques?
Myocardial scanning and routine cardiac enzymes correlate excellently in diagnosing perioperative MI after CABG, whereas ECG is less helpful and CK-MB offers no additional diagnostic advantage.
McGregor et al. (1984) conducted a cohort in chronic stable angina (n=50). Coronary artery bypass grafting was evaluated on incidence of perioperative myocardial infarction. Coronary artery bypass grafting for chronic stable angina was associated with a 14% incidence of perioperative myocardial infarction.
