Main Outcome Measure ADP-stimulated platelet aggregation in response to clopidogrel treatment and cardiovascular events. Conclusion CYP2C19*2 genotype was associated with diminished platelet response to clopidogrel treatment and poorer cardiovascular outcomes. platelet function in response to clopidogrel has been associated with lipophilic statins, calcium channel blockers, proton pump inhibitors, St John's antiplatelet effect19-23 and with increased cardiovascular events in patients receiving clopidogrel.18,24-26 Indeed, follow-up genotyping indicated that the common lossof-function CYP2C19*2 variant was associated with clopidogrel response and replication of the initial association between CYP2C19*2 genotype and clopidogrel response, the Baltimore Sinai We report the first genome-wide association study of clopidogrel response ./cache/work_tpiqgspaqvfeng2fovbximt4lm.pdf ./txt/work_tpiqgspaqvfeng2fovbximt4lm.txt
