Study Summary

This clinical trial is examining the role of genetic polymorphism on the effect of clopidogrel (with or without aspirin) on platelet response in persons at high-risk for myocardial infarction or stroke due to family history of early-onset coronary artery disease.

Primary Outcome

ADP-induced platelet aggregation will be measured using impedance aggregometry in whole blood before and after 1-week of clopidogrel. The difference between the baseline and after clopidogrel therapy will be determined. Higher impedance represent higher platelet aggregation.

Interventions

  • DRUG Aspirin
  • DRUG Clopidogrel
