Commentary: Spontaneous myocardial infarctions and the vital choice: Bypass or stent

[摘要] Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) have been compared in numerous randomized control trials (RCT) over 25 years. Both treat coronary artery disease (CAD) to relieve angina and myocardial ischemia but in very different ways. While flow-restricting coronary artery stenosis is locally dilated by PCI, a new inflow of blood supply through a bypass graft is constructed distal to the stenosis in CABG, an effect called “surgical collateralization.” Particularly in severe CAD, that difference is believed to give rise to a difference in protection against subsequent spontaneous myocardial infarction (SMI).
