Brief Summary:

The aims of the study are to:

  • explore whether platelet reactivity in patients treated wih novel platelet inhibitors is associated with clinical outcome
  • investigate whether a therapeutic window exist for novel platelet inhibitors
  • investigate the incidence of adverse events under treatment with novel platelet inhibitors in the real life clinical scenario
  • investigate the association between genetic polymorphisms, inflammation, platelet reactivity and clinical outcome
  • investigate synergistic effects between aspirin and novel platelet inhibitors

Condition or disease
