Standard (180mg) Versus Double (360mg) Loading Dose of Ticagrelor in Patients With ST-elevation Myocardial Infarction (STEMI), Undergoing Primary Percutaneous Coronary Intervention (PCI)

ST-elevation Myocardial Infarction Clinical Trial

Official title:
Standard (180mg) Versus Double (360mg) Loading Dose of Ticagrelor in Patients With ST-elevation Myocardial Infarction (STEMI), Undergoing Primary Percutaneous Coronary Intervention (PCI): a Multi-center Randomized Parallel Pharmacodynamic Study.

Clinical Trial Summary

This is a multi-center, prospective, randomized, single-blind, investigator initiated, pharmacodynamic study of parallel design, performed at 3 institutions (Patras University Hospital; Evangelismos Athens General Hospital; Gennimatas Athens General Hospital).

Patients with ST elevation myocardial infarction (symptom onset < 12 hours), undergoing primary percutaneous coronary intervention, who are antiplatelet naïve (Group A) or present high residual PR (defined as PRU ≥ 208) immediately before primary percutaneous coronary intervention, will be randomized after informed consent, in a 1:1 ratio to either:

Ticagrelor 180mg loading dose (LD), followed by a 90mg x2 maintenance dose (MD )starting 12±6 hours post LD Or Ticagrelor 360mg loading dose (LD), followed by a 90mg x2 maintenance dose (MD) starting 12±6 hours post LD Platelet reactivity assessment will be performed at randomization (Hour 0) and at 0.5, 1, 2, 4 hours after randomization, using the VerifyNow assay, in platelet reactivity units (PRU).

Documentation of major adverse cardiac events (death, myocardial infarction, stroke, urgent revascularization procedure with PCI or CABG) and bleeding (according to Bleeding Academic Research Consortium criteria) will be performed until patient's discharge.
