Different Dosage of Domestic and Imported Clopidogrel on the Platelet Inhibition Ratio in Patients Undergoing PCI
This is a single-center, randomized, single-blind, investigator-initiated, pharmacological study with a parallel design. Patients with non-ACS undergoing primary percutaneous coronary intervention will be randomized after informed consent, in a 1:1:1:1 ratio to the following treatment groups:
Group Α: Domestic Clopidogrel 300mg as a loading dose before PCI, followed by 75mg per day.
Group B: Domestic Clopidogrel 600mg as a loading dose before PCI, followed by 75mg per day.
Group B: Imported Clopidogrel 300mg as a loading dose before PCI, followed by 75mg per day.
Group D: Imported Clopidogrel 600mg as a loading dose before PCI, followed by 75mg per day.
Platelet inhibition ratio assessment by thrombelastogram will be performed,2 hours after the loading dose(Day 0), 6 hours after thrombelastogram (Day 0), 30 day after thrombelastogram. Documentation of major adverse cardiac events (death, myocardial infarction, stroke, revascularization procedure with PCI or CABG) and serious adverse events (bleeding, other adverse events)will be performed until Day 30.
