NPPB and myocardial infarction: The incidence of AMI has been increasing year by year and is tending to be younger.[30] PCI is the preferred method for acute myocardial infarction, and myocardial ischemia-reperfusion injury may occur after surgery, resulting in slow postoperative recovery of cardiac function in patients.[31] In addition, PCI may promote the release of local inflammatory factors and vascular endothelial damage, leading to postoperative MACE.[32] This study will discuss the efficacy and safety of TCMI in treating AMI from LVEF, hs-CRP, NT-proBNP, MACE, IL-6, and other aspects.
