Overview
Brief Summary
We compared the infarct size in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) treated by nicorandil before and after the reperfusion with those standard therapy treated by PCI
Detailed Description
The aim of this study was to evaluate the efficacy and safety of nicorandil in improving myocardial infarct size in patients with acute myocardial infarction through a multi-center, prospective, randomized, double-blind and parallel-controlled clinical study, providing evidence-based support for the optimization of PCI treatment strategies. The primary objective of the study was to compare whether the effect of nicorandil in combination with PCI was significantly better at reducing the myocardial infarct size than that of PCI alone in AMI patients.

Arms & Interventions
Treatment arm
Patients were randomly assigned to two groups before emergent coronary angiography: those who received intravenous (iv.) nicorandil before and after (ivgtt.) reperfusion with PCI (nicorandil group);
Intervention: Nicorandil
Placebo arm
Patients were randomly assigned to two groups before emergent coronary angiography, those who received placebo before and after reperfusion with PCI.
Intervention: Placebo
Outcomes
Primary Outcomes
Infarct size as measured by cardiac MRI
Time Frame: 7 days after primary PCI
The myocardial infarct size was derived by measuring the area of delay-enhanced image-enhanced MRI, which was judged and analyzed by two experienced MRI cardiac diagnosticians.
Secondary Outcomes
- Corrected thrombolysis in myocardial infarction (TIMI) frame count (cTFC)(5 minutes after stent implantation during PCI)
- Incidence of slow flow/no-reflow(5 minutes after stent implantation during PCI)
- CIN(48-72 hours after primary PCI)
- Infarct size as measured by cardiac MRI(6 months after PCI)
- Serum creatinine kinase (CK-MB) level(Baseline, 6, 12, 18, 24 hours after the PCI)
- Microvascular obstructionmeasured by cardiac MRI(7 days after the procedure)
- MACE(up to 12 months)
- ST-segment fall rate of electrocardiogram (ECG)(2 hours after the procedure)
- Edema size (LV area %) measured by cardiac MRI(7 days after the procedure)
- LV Ejection fraction (%) as measured by cardiac MRI(6 months after the procedure)
