Optimal Dosage of Ticagrelor in Korean Patients With AMI
January 14, 2022 updated by: Moo Hyun Kim, Dong-A University
The Early De-escalation Strategy With Ticagrelor 60 mg or 45 mg on Platelet Reactivity and Clinical Outcomes in Korean Patients With Acute Myocardial Infarction
East Asian patients will be required optimal dose of newer P2Y12 inhibitor (ticagrelor) to determine the safer treatment and better outcome.
Whether low dose of ticagrelorI is more adequate for clinical practice in Korea is unclear.
Therefore, the investigators aim to evaluate efficacy and safety of low dose of ticagrelor in Acute Myocardial Infarction (AMI) undergoing percutaneous coronary intervention(PCI).

Detailed Description
In recent years, newer oral P2Y12 receptor blocker (ticagrelor) has been strong recommendations for management of patients with AMI undergoing (PCI).
This drug provided more profound inhibitory effects than clopidogrel, which could lead to marked reduction in ischemic events, with relatively increase in bleeding complication, specific to low body weight, especially in women and East Asian patients.
