Platelet Function in Patients With an Acute Coronary Syndrome (ATLANTIS-ACS)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified November 2013 by Jolanta Siller-Matula, Medical University of Vienna.
Recruitment status was:  Recruiting

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

Acute Coronary Syndrome (ACS)

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Association Between the Antiplatelet Drug Efficacy/Safety and Platelet Function in Patients Treated With Novel Platelet Inhibitors Due to an Acute Coronary Syndrome

Further study details as provided by Jolanta Siller-Matula, Medical University of Vienna:
