Study Summary

One of the most common ways for preventing coronary heart disease (CHD) is to take aspirin or clopidogrel. However, studies have shown that not all people respond to these medications. The variance in treatment response may be linked to genetics. This study will examine the effects of aspirin and clopidogrel in a population whose genes are well known in order to determine the role that genes play in treatment responses.

Primary Outcome

Baseline minus post clopidogrel/pre-aspirin platelet rich plasma (PRP) maximum aggregation.

Interventions

  • DRUG Aspirin
  • DRUG Clopidogrel
