Abstract:
Objective: To observe therapeutic effects of ticagrelor combined tirofiban on patients with ST elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI) and their short-term prognosis.Methods: A total of 280 STEMI patients undergoing emergency PCI were selected.According to random number table, patients were randomly divided into clopidogrel group (received clopidogrel combined tirofiban therapy) and ticagrelor group (received ticagrelor combined tirofiban therapy).TIMI blood flow grade of infarct related arteries, platelet aggregation rate and P2Y12 reaction unit (PRU) before and after PCI, and incidence of major adverse cardiovascular events (MACE) within 30d follow-up, hemorrhage event and cardiac function were measured and compared between two groups.Results: Compared with clopidogrel group after PCI, there was significant rise in percentage of TIMI blood flow grade 3 (81.4% vs.91.4%), and significant reductions in platelet aggregation rate [(55.2±4.1)% vs.(50.8±4.4)%] and PRU [(196.2±15.1)U vs.(180.8±12.0)U] in ticagrelor group, P<0.05 all.Compared with clopidogrel group after 30d follow-up, there were significant reductions in incidence rates of re-myocardial infarction (5.0% vs.2.9%) and cardiogenic death (2.9% vs.0.7%), left ventricular end-diastolic dimension [(53.1±2.8)mm vs.(49.0±2.0)mm] and left ventricular end-systolic dimension [(40.2±2.1)mm vs.(37.4±1.8)mm], and significant rise in left ventricular ejection fraction [(51.8±2.7)% vs.(55.4±2.5)%] in ticagrelor group, P<0.05 all.There were no severe hemorrhage events in both groups, and no significant difference in incidence rate of mild hemorrhage (5.0% vs.6.4%) between clopidogrel group and ticagrelor group, P=0.591.Conclusion: For STEMI patients undergoing emergency PCI, ticagrelor combined tirofiban can effectively reduce platelet aggregation rate, improve TIMI blood flow of infarct related arteries, therapeutic effects and their short-term prognosis without increasing hemorrhage risk, which is worth extending.
