急診PCI治療中應(yīng)用替格瑞洛對(duì)STEMI患者微血管損傷及心功能的影響
[Abstract]:Objective to investigate the effect of tigrilol on microvascular injury and cardiac function in patients with ST segment elevation myocardial infarction (STEMI) treated with emergency PCI. Methods Eighty-five patients with PCI were randomly divided into two groups: tigrillo group (n = 44) and clopidogrel group (n = 41). Both groups were treated with emergency PCI. The maintenance dose of tigrilol was 90 mg/ d before operation in tigrello group, and 75 mg/ d / d in clopidogrel group before and after clopidogrel 600 mg,. Both groups were treated for 12 months. Microcirculation resistance index (IMR) was monitored immediately after operation in both groups. Mean Aortic pressure (Pd) of distal Coronary artery in (Pa), and mean conduction time of normal Saline flow under maximum congestive condition (Rest Tmn), calculation of Blood flow Reserve at rest of normal Saline flow (FFR), coronary flow reserve fraction (CFR) and IMR. Echocardiography was performed 24 hours after operation and 3 months after operation in both groups. End diastolic volume (EDV), end-systolic volume (ESV), left ventricular ejection fraction (LVEF) and wall motion index (WMSI).) were recorded. Results the Hyper Tmn,IMR of tigrilol group was lower than that of clopidogrel group (P 0. 05). There was no significant difference in Pa,Pd,Rest Tmn,FFR,CFR between the two groups (P 0. 05). The WMSI of the two groups at 3 months after operation was lower than that of the same group at 24 h (P. There was no significant difference in WMSI between the two groups at 3 months after operation (all P 0.05). There was no significant difference in EDV,ESV,LVEF between the two groups 24 hours after operation and 3 months after operation (P 0.05). Conclusion the application of tigrilol in emergency PCI treatment for STEMI patients is more helpful to alleviate microvascular injury and improve cardiac function than clopidogrel.
