Summary

This is a single-center, prospective, randomized, single-blind, investigator initiated, pharmacokinetic/pharmacodynamic study of parallel design.Patients with ST elevation myocardial infarction (symptom onset\<12 hours), undergoing primary percutaneous coronary intervention, who are P2Y12 inhibitor naïve, will be randomized after informed consent, immediately after diagnostic coronary angiography, in a 1:1 ratio to either:

* Ticagrelor 180mg loading dose, in the form of 2 whole tablets administered per os in the supine position (standard administration)
* Ticagrelor 180mg loading dose, in the form of 2 tablets crushed and dispersed in purified water and administered per os with 1-minute-stay in a 60-70 degrees semi-upright sitting position Platelet reactivity assessment will be performed at randomization (Hour 0) and at 0.5, 1, 2, 4 and 6 hours after randomization, using the VerifyNow assay, in platelet reactivity units (PRU). The cutoff \>208 PRU will be used for definition of high platelet reactivity (HPR). All platelet reactivity assessments will be performed by a physician blind to the actual treatment given. Additional blood samples will be collected at the same time points for pharmacokinetic analysis. These samples will be collected in vacuum tubes with lithium heparin and will be kept in ice until centrifugation (3000 rpm at 4°C for 10 min, within 30 min of sampling). The resultant plasma will be transferred into a plain polypropylene tube (screw cap) and stored at or below -20°C until analysed.
