Abstract：【Objective】To investigate the effects of reteplase combined with bivalirudin on the blood flow grade of myocardial infarction thrombolysis test (TIMI) and the occurrence of major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). 【Methods】A total of 114 AMI patients who underwent PCI in our hospital was prospectively selected and randomly divided into observation group (Reteplase combined with bivalirudin) and control group (Reteplase treatment), 57 cases in each group. TIMI blood flow grade, cardiac function indexes [left ventricular end diastolic volume (LVEDV), left ventricular end systolic volume (LVESV), vascular resistance (SVR), left ventricular ejection fraction (LVEF), serum vascular endothelial function indexes nitric oxide (NO), nitric oxide synthase (NOS), endothelin (ET-1)],serum myocardial injury indexes [lactate dehydrogenase (LDH), troponin (cTNI) and creatine kinase isoenzyme (CK-MB)] were compared between the two groups. The incidence of MACE at 1 month after operation was recorded. 【Results】One week after operation, the proportion of TIMI blood flow grade 3 and LVEF level in the observation group were higher than those in the control group, and the levels of LVEDV, LVESV and SVR in the observation group were lower than those in the control group (P<0.05); One week after operation, the levels of serum LDH, cTNI, CK-MB and ET-1 in the observation group were lower than those in the control group, the levels of serum NO and NOS in the observation group were higher than those in the control group (P<0.05). The incidence of mace in the observation group one month after operation was lower than that in the control group, the difference was statistically significant (P<0.05). 【Conclusion】Reteplase combined with bivalirudin can significantly improve myocardial perfusion, cardiac function and vascular endothelial function, reduce myocardial injury and effectively reduce the incidence of MACE in patients with AMI after PCI.
