Can doubling the maintenance dose of clopidogrel prevent from early stent thrombosis after the primary percutaneous coronary intervention?

Background: Treatment of significant coronary artery disease with primary percutaneous coronary intervention (PCI) seems better than angioplasty balloon; because the incidence of restenosis is lower in this method, however, a serious complication of PCI is stent thrombosis which would lead to repeated myocardial infarction (MI) and increase the mortality and morbidity. One of the frequent medications which is used to prevent from stent thrombosis is clopidogrel, but, stent thrombosis was seen in many of the patients despite given the conventional dosage of this drug. This study aimed to evaluate the effect of doubling the maintenance dose of clopidogrel to prevent from early stent thrombosis, MI and mortality rate.
