Treatments
Studied treatment |
cangrelor up front (cangrelor administered before percutaneous coronary intervention and followed by clopidogrel)
cangrelor (intravenous bolus of 30 �g/kg
followed by intravenous infusion
of 4 �g/kg/min) began within 30 minutes before PCI and continued for at least 2 hours or until the conclusion of the index procedure. 600 mg of clopidogrel at the time of infusion and at discontinuation of infusion
|
Control treatment |
clopidogrel up front (clopidogrel followed by placebo)
placebo at
the discontinuation of the study-drug infusion (before oral clopidogrel)
|
Concomittant treatment |
75 to 325 mg of aspirin
according to local-site standards |
Remarks |
cangrelor then clopidogrel vs clopidogrel then placebo |
