ABSTRACT
INTRODUCTION: Of recognized fact the importance of early diagnosis and early management of ST-elevation myocardial infarction, to regain a normal or at least adequate coronary flow in the Primary Percutaneous Intervention. Slow or no-reflow is suboptimal myocardial reperfusion, without angiographic evidence of mechanical obstruction. Adenosine, Verapamil and saline flush are manoeuvres proved useful. The resolution of ST-segment is associated with successful revascularization and regarded as a predictor for future events. Glycoprotein IIB/IIIA inhibitors are a group of anti-platelets widely used in acute coronary syndrome. AIM: The aim of the study was to investigate that: uses of intra venous Abciximab, does not improve coronary flow in patients with MI that develop sub optimal flow after primary PCI within 30 minutes, but the improvement need 12 to 24 hour as founded in other studies, and its beneficial effect is related to early improvement in LV function and decrease of re-infarction and re-hospitalization. METHOD: Prospective, case-control study, enrolled fifty patients randomly assigned into two matching groups, first group (25 patients) received an intravenous Abciximab while the second group (25 patients) received intracoronary saline flush. Repeated angiography after 30 minutes, for immediate resultant flow assessment, Electrocardiographic changes resolution, bleeding and death. After a 30 days, a clinical assessment for primary outcome including, death, recurrent Myocardial infarction and Heart failure While the Secondary outcome including stent thrombosis, target vessel revascularization in addition to the primary outcome. RESULT: There was no significant difference in the flow Improvement and ECG resolution between both groups. These findings not affected by the door to balloon time. However, patients with flow improvement had a significant resolution in their ECG. Bleeding propensity and mortality were not significantly affected. Literatures proved the benefit of Abciximab in acute coronary syndrome. CONCLUSION: Both intravenous Abciximab and intracoronary saline flush had comparable effect on coronary flow improvement post primary percutaneous intervention, with minimal variation in the bleeding and in-hospital mortality.
