About this trial

This is an interventional treatment trial for Acute Myocardial Infarction focused on measuring Ticagrelor, De-escalation strategy, East Asian

Eligibility Criteria

20 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients present with acute myocardial infarction undergoing PCI.
  • Patients receive potent DAPT (Ticagrelor 180 mg loading dose followed by 90 mg twice daily plus Aspirin 300 mg loading dose followed by 100 mg daily).

Exclusion Criteria:

  • History of transient ischemic attack or stroke.
  • History of upper gastrointestinal bleeding in recent 6 months.
  • Renal dysfunction defined as serum creatinine > 2.5 mg/dl.
  • Severe hepatic dysfunction defined as serum transaminase > 3 times normal limit.
  • On treatment with oral anticoagulant (Vitamin K antagonists, dabigatran, rivaroxaban).
  • Bleeding tendency.
  • Thrombocytopenia defined by platelet < 100,000/ml.
  • Anemia defined by hemoglobin < 10 g/dl.
  • Current treatment with drugs interfering with CYP3A4 metabolism (to avoid interaction with Ticagrelor): Ketoconazole, itraconazole, voriconazole, clarithromycin, nefazodone, ritonavir, saquinavir, nelfinavir, indinavir, atazanavir, and telithromycin.
  • Known severe chronic obstructive pulmonary disease or bradycardia (sick sinus syndrome (SSS) or high degree AV block without pacemaker protection).

5. Study Description

Brief Summary
Ticagrelor as nonthienopyridine, direct-acting P2Y12 receptor antagonist, had significantly greater platelet inhibition, which could reduce ischemic events at acute phase, however, resulting in more incidence of bleedings than pro-drug P2Y12 receptor inhibitor during chronic phase for management of acute myocardial infarction (AMI) following percutaneous coronary intervention (PCI). Also, East Asians have higher response to potent agent, like ticagrelor, when compared with Caucasians. With this in mind, East Asian patients will be required optimal, potentially reduced dose of ticagrelor to improve the safety profile, maintaining better vascular outcomes. Similarly, there are insufficient East Asian data on the efficacy and safety of low-dose ticagrelor in real-word practice. Whether the de-escalation strategy (ticagrelor 60/45 mg twice daily) are more adequate for clinical practice in East Asian is unclear. Therefore, the investigators design the EASTYLE study, hypothesis that low-dose ticagrelor would be more likely adequate for optimal antiplatelet treatment without increasing ischemic and bleeding events in East Asian with AMI compared with standard-dose ticagrelor. In the EASTYLE trial, further clinical data of de-escalation strategy guided AMI management in East Asian will be provided.
Detailed Description
In EASTYLE trial, the investigators aim to evaluate the efficacy and safety of de-escalation strategy ticagrelor (60/45 mg twice daily), as compared with standard strategy ticagrelor (90 mg twice daily) in East Asian patients with AMI undergoing PCI. All eligible AMI patients receive loading dose of ticagrelor 180 mg plus aspirin 300 mg, following ticagrelor 90 mg twice daily plus aspirin 100 mg daily during the index hospitalization. Subsequently, to be randomly assigned into ticagrelor 90 mg and ticagrelor 60/45 mg twice daily in combination with aspirin 100 mg daily at discharge for at least 12-month period treatment. The investigators focusing on the efficacy and safety endpoint, is net adverse clinical and cerebrovascular events (NACCE), composite of all-cause mortality, myocardial infarction, stroke, and major bleeding.
