CAD = coronary artery disease; MI = myocardial infarction; PCI = percutaneous coronary intervention.
↵∗ A total of 25.7% patients underwent PCI. Most patients had no culprit lesion to intervene upon. These patients experienced perioperative MI secondary to demand and supply imbalance during the perioperative period. 6.7% patients actually had severe CAD, who, in the best judgment of the operating interventionist and consulting surgeon, were candidates for coronary artery bypass grafting. Also, 5.7% of patients were considered to be at too great a risk for bleeding and, according to the best judgment of the operating interventionist, would benefit from delayed PCI (beyond the 7 days after surgery cutoff, and therefore not included in our study).
