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.
- to characterize the proteome profile of platelet hyperreactivity in aspirin-treated cardiovascular patients
- to characterize the platelet hyperreactivity phenotype in cardiovascular patients treated with aspirin
- to determine genetic polymorphisms associated with platelet hyperreactivity
