Periprocedural myocardial infarction during PCI: predict and prevent

In about 30 % of patients undergoing coronary revascularisation by planned percutaneous coronary intervention (PCI), the procedure itself results in periproce-dural myocardial necrosis.1 This form of PCI-related myocardial injury, which is often clinically silent, can be detected as an increase in serum cardiac enzymes above the 99th centile upper reference limit.2 Periprocedural myocardial necrosis following PCI, as measured by raised levels of serum troponin, has been shown to be associated with higher major adverse cardiac events (MACE), with a twofold and threefold increased risk of overal
