Clinical efficacy of ticagrelor in patients undergoing emergency intervention for acute myocardial infarction and its impact on platelet aggregation rate.

Objective: This study aims to investigate the clinical efficacy of ticagrelor in patients who underwent emergency percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI), and its impact on platelet aggregation rate.

Methods: A total of 257 AMI patients who underwent emergency PCI in our hospital were included in the present study. These patients were randomly divided into two groups: ticagrelor group ( = 129), patients took 180 mg of ticagrelor () before the intervention, and subsequently took 90 mg of ticagrelor () for maintenance; clopidogrel group ( = 128), patients took 300 mg of clopidogrel () before PCI, and subsequently took 75 mg of clopidogrel () for maintenance.
