This Randomized controlled intervention study recruited patients diagnosed with ST-segment elevation myocardial infarction (STEMI). A total of 240 patients were enrolled in either Henagliflozin group or control group. Patients in Henggliflozin group will be given by oral administration of Henggliflozin for 6 months post acute myocardial infarction. Prior to procedure, dynamic changes in myocardial enzymes were monitored. Major cardiovascular events, including non-fatal myocardial infarction, all-cause death, revascularization due to angina, and hospitalization for acute heart failure. This study aims to assess the impact of Henggelizin intervention on the reduction of myocardial infarction size (evaluated by cardiac enzyme) and improvement of left ventricular remodeling in patients with ST-segment elevation myocardial infarction.

This Randomized controlled intervention study recruited patients diagnosed with ST-segment elevation myocardial infarction (STEMI) who were scheduled to undergo emergency percutaneous coronary intervention (PCI) . A total of 240 patients were selected for both the Henagliflozin group and control group. In the emergency room, clinical data would be collected, along with peripheral venous blood samples for laboratory examination. This examination should include blood routine analysis, myocardial enzyme, blood glucose levels, liver and kidney function, and brain natriuretic peptide precursor (NT proBNP) measurement. After primary PCI, Henggliflozin was administered, followed by daily oral administration of one tablet until 6 months post-acute myocardial infarction. Prior to procedure, dynamic changes in myocardial enzymes and electrocardiogram were monitored, with subsequent monitoring at 6 hours, 24 hours, and 48 hours after myocardial infarction. Perioperative complications were documented, followed by cardiac ultrasound assessments of myocardial wall motion and cardiac structure at seven days post primary PCI and six months post procedure. Major cardiovascular events, including non-fatal myocardial infarction, all-cause death, revascularization due to angina, and hospitalization for acute heart failure, were observed through follow-up at 1 month, 2 months, 3 months, and 6 months after PCI. This study aims to assess the impact of postoperative Henggelizin intervention on the reduction of myocardial infarction size and improvement of left ventricular remodeling in patients with ST-segment elevation myocardial infarction (STEMI).
