Abstract 19565: The Safety and Efficacy of Platelet Glycoprotein Iib Iiia Antagonist by Intracoronary Administration versus Intravenous Administration in Patients With St Segment Elevation Myocardial Infarction: A Meta-analysis
Objective: Evaluate the administration (IC) and intravenous(IV) administration of platelet glycoprotein IIb / IIIa antagonist in STEMI patients.
Methods: We searched PubMed, EMBASE, Web of Science, the Chinese Biomedical Medical Literature database, and the Cochrane Library, the retrieval time is May 2015. The papers which compared the safety and efficacy of IC and IV STEMI patients with platelet glycoprotein IIb / IIIa antagonist were included.Two researchers evaluated the trails and collected data according to 5.0.2 Cochrane Handbook. The data were merged by RevMan 5.0 software.
Results: Finally we included 17 RCTs(n=8279, including 4260 IC administration patients, and 4019 IV administration patients). The GP IIb / IIIa antagonist was injected in the coronary after stent releasing during PCI in the IC group. Meta analysis showed: In the STEMI trials, intracoronary group had better clinical outcomes than intravenous group in the following index: short time MACE (one month after PCI) [OR=0.47,95%CI:0.23-0.97], congestive heart failure [OR=0.59,95%CI:0.41-0.84], left ventricular ejection fraction [MD=1.11, 95%CI: 0.48-1.74], infarct size [MD=-1.00, 95%CI: -1.65~ -0.35], myocardial blush grade 3 [OR=1.60, 95%CI: 1.12-2.27], drug occupational rate [OR=4.16, 95%CI: 1.45-11.92], wall motion score index[MD=-0.27,95%CI: -0.51~ -0.03]. And the IC and IV group were similar in the death, long time MACE(1 year after PCI), stent thrombosis, sever bleeding, ST-segment resolution -1 month after PCI, target vessel revascularization, myocardial infarction recurrence, TIMI grade 3 after PCI, left ventricular end systolic volume, left ventricular end diastolic volume, intervention success rate, life threatening arrhythmia, stroke after PCI, CK-MB, operation time, E/ A, cardiac death, minor bleeding, with no significant difference (P> 0.05).
Conclusions: This updated meta-analysis shows, compared to the IV, IC administration of platelet glycoprotein IIb / IIIa antagonist could reduce the risk of short time MACE (one month after PCI), congestive heart failure, and improve left ventricular ejection fraction, so IC administration of platelet glycoprotein IIb / IIIa antagonist could be a considerable way to be used in STEMI patients.
