Study Summary

Loss-of-function mutation of the gene encoding the CYP450 2C19 enzyme has emerged as a likely determinant of resistance to clopidogrel therapy. The primary hypothesis of the proposed research is that among patients with confirmed loss-of-function alleles of the CYP2C19 gene, increasing the maintenance clopidogrel dose from 75 to 150 mg will result in significant reduction in the rate of measured clopidogrel resistance defined by multiple measures of platelet function

Primary Outcome

P2Y12 Reaction Units are measured using the VerifyNow P2Y12 assay. Percent of patients with clopidogrel resistance defined by PRU value will be compared among low and high dose clopidogrel groups after 30 days of therapy.
