简要总结

By including patients with acute myocardial infarction, mast cell markers were analyzed and the relationship between mast cells and patients with acute myocardial infarction was analyzed

详细描述

Percutaneous coronary intervention (PCI) is the best way to improve the prognosis of patients with acute ST-segment elevation myocardial infarction (STEMI). However, ischemia reperfusion injury, inappropriate ventricular remodeling, and myocardial fibrosis may still be present in STEMI after PCI, which may be related to the inflammatory response in STEMI. Mast cells (MC), their degranulation products and induction of a series of inflammatory cytokines play an important role in the inflammatory response. The purpose of this study was to evaluate the relationship between mast cell markers (trypsin, chymotrypsin) levels and prognosis after direct PCI in STEMI patients. We prospectively and continuously included STEMI patients undergoing standard therapy after direct PCI. Clinical data and blood samples were collected and followed up for 1 year to analyze mast cell markers and myocardial infarction size. As well as differences in echocardiography, markers of two-dimensional speck tracking techniques, inflammatory factors and major adverse cardiovascular events, to explore the relationship between mast cells and their products and ventricular remodeling and ischemia-reperfusion injury in STEMI patients, and to provide new ideas for treatment and new basis for optimization of STEMI treatment strategies.
