Efficacy and Safety of an Early Phase Single Bolus r-SAK for Acute Myocardial Infarction: a Multi-center Randomized Clinical Trial (OPTIMA-5)

Detailed Summary

This study was a prospective, multicenter, randomized, controlled, excellence clinical trial. Subjects meeting the inclusion/exclusion criteria were randomly assigned 1:1 to r-SAK group or the control group (normal saline). Emergency coronary angiography was performed and cardiac magnetic resonance imaging was performed 5 days after surgery, followed up to 30 days. At present, there is still a lack of clinical evidence on whether thrombolytic therapy is performed for acute ST-segment elevation myocardial infarction \<2 hours after the first medical contact and prime PCI. Compared to prime PCI, early thrombolytic therapy can undoubtedly shorten the implementation time of reperfusion strategy to the maximum. For highly effective thrombolytic drugs, it should also shorten the reperfusion time, reduce thrombotic load, possibly reduce the area of myocardial infarction and improve the prognosis of patients. In this study, normal saline was used as the control. To observe the efficacy of thrombolytic therapy with single intravenous infusion of recombinant glucokinase (r-SAK) at the first time in acute ST-segment elevation myocardial infarction. And the effect of r-SAK on improving myocardial tissue level perfusion, reducing myocardial infarction size, improving cardiac function and clinical prognosis in STEMI patients.
