Platelet Hyperreactivity Project: A System Biology Approach of High On-treatment Platelet Reactivity in Aspirin-treated Cardiovascular Patients

The PHP study aims to delineate gene products involved in high on-treatment platelet reactivity in aspirin-treated cardiovascular patients.

Detailed Description

The PHP study aims to delineate gene products involved in high on-treatment platelet reactivity in aspirin-treated cardiovascular patients using a system biology approach that include proteomics analysis of selected platelet sub-fractions in patients displaying extreme phenotype.

Main objective:

  • to characterize the proteome profile of platelet hyperreactivity in aspirin-treated cardiovascular patients

Secondary objectives:

  • to characterize the platelet hyperreactivity phenotype in cardiovascular patients treated with aspirin
  • to determine genetic polymorphisms associated with platelet hyperreactivity
