Platelet Inhibition After Pre-hospital Ticagrelor Using Fentanyl Compared to Morphine in Patients With ST-segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention
- Conditions
- Acute Myocardial Infarction
- Interventions
- Procedure: Primary PCI
- Registration Number
- NCT02531165
- Lead Sponsor
- Centre Hospitalier Universitaire Vaudois
- Brief Summary
Prospective, randomized, open-label, single-center, investigator-initiated trial, including patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) within 12 hours of the symptom's onset. The study aims to compare platelet inhibition (pharmacodynamics and pharmacokinetics) of pre-hospital Ticagrelor in patients with STEMI according to two different analgesia protocols using Fentanyl or Morphine.
- Detailed Description
Consecutive patients with acute STEMI within 12 hours of the symptoms' onset and candidates for PPCI will be screened for inclusion in the study. Eligible patients who require analgesia for the relief of acute chest pain, defined as Visual Analogue Scale ≥3, will be randomized in a 1:1 ratio into one of the two treatment arms to receive analgesia with either Morphine or Fentanyl following administration of a pre-hospital loading dose of Ticagrelor. Randomized patients will undergo primary PCI and managed according to the current guidelines of the European Society of Cardiology. Blood samples (10 ml) will be collected at 0, 1, 2, 4, 6, 12 and 24 hours after the loading dose of Ticagrelor to assess platelet inhibition using the VerifyNow P2Y12 function and the Vasodilator-Stimulated-phosphoprotein Phosphorylation (VASP) assays, plasma concentration of Ticagrelor and its active metabolite (AR-C124910XX) using a validated liquid chromatography/mass spectrometry detection method and the procoagulant action of platelets.
