Brief summary
The ELECTRA pilot study is a randomized, open-label, pharmacokinetic and pharmacodynamic trial designed to evaluate the effect of ticagrelor maintenance dose reduction on platelet inhibition in stable patients who recently underwent acute myocardial infarction and were treated with percutaneous coronary intervention.
Interventions
Ticagrelor 90 mg twice daily
Ticagrelor 60 mg daily
