NCT02587260

Brief Summary

The purpose of this randomized, cross-over study, is to ascertain if ticagrelor, but not prasugrel or clopidogrel, is associated to an improved endothelial function as assessed with peripheral arterial tonometry and markers of endothelial function measurement in post-ACS patients.

Outcome Measures

Primary Outcomes (1)

  • Improvement of endothelial function at steady state

    Evaluation if ticagrelor, at steady state (i.e. after 30 day therapy), will be associated to an improved endothelial function as compared to clopidogrel or prasugrel when assessed with endopath system 1-2 hour(s) after maintenance drug intake.

    After 30 days of therapy with assigned P2Y12-inhibitor

Secondary Outcomes (1)

  • Improvement of endothelial function, both acutely and at steady state

    One or 2 hour(s) after P2Y12-inhibitor loading dose administration and before and 1 or 2 hour(s) after maintenance dose administration

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients older than 18 years.
  • Patients who experienced an Acute Coronary Syndrome (including STEMI or NSTEMI) at least 30 days before.
  • Patients on ongoing treatment for at least 30 days with dual anti-platelet therapy consisting of aspirin, at doses of 75-160 mg daily and one commercially available P2Y12 oral inhibitor , including ticagrelor, clopidogrel or prasugrel.

You may not qualify if:

  • Administration of fibrinolytics or glycoprotein IIb/IIIa inhibitors in the previous 30 days.
  • Major surgery within 30 days or any planned surgical or percutaneous intervention.
  • Active bleeding or previous clinical relevant bleeding or stroke in the last 6 months.
  • Previous transient ischemic attack or intracranial bleeding.
  • Thrombocytopenia.
  • Oral anticoagulant therapy.
  • Vasculitis or any know immunological disorder.
  • Severe hepatic failure.
  • Uncontrolled hypertension (systolic or diastolic arterial pressure \>180 mmHg or 120, respectively, despite medical therapy).
  • Known intolerance to aspirin or to clopidogrel or prasugrel or ticagrelor.
  • Limited life expectancy, e.g. neoplasms, others.
  • Inability to obtain informed consent.
  • Pregnancy.
