This trial targeted to analyze the effects of different doses of tirofiban combined with dual antiplatelet drugs on platelet indices, vascular endothelial function, and major adverse cardiovascular events (MACE) in patients with acute ST-segment elevated myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). A total of 180 patients with STEMI who underwent PCI were divided into Group A, Group B, and Group C (60 cases per group). Group A was given conventional medication, and Groups B and C were given a standard dose (10 μg/kg) and a high dose (20 μg/kg) of tirofiban on the basis of Group A, respectively. Thrombolysis in myocardial infarction (TIMI) myocardial perfusion grade and TIMI blood flow grade were compared. Myocardial enzymes, platelet indices, vascular endothelial function, inflammatory factors, and cardiac function indices were detected. In-hospital bleeding events and follow-up MACE were recorded. After PCI, Group C had a higher number of TIMI myocardial perfusion grade III and TIMI blood flow grade III versus Group A. Group C achieved the greatest changes in myocardial enzymes, platelet indices, vascular endothelial function-related factors, inflammatory factors, and cardiac function indices, followed by Group B and Group A. The incidence of bleeding events was higher in Group C than in Group A, and that of MACE in Group C was lower than in Group A. The addition of high-dose tirofiban to PCI and dual antiplatelet drugs for STEMI patients can improve myocardial blood perfusion, cardiac function, and vascular endothelial function, inhibit platelet activation and aggregation, and reduce the occurrence of MACE.
