percutaneous coronary intervention


This study evaluates the efficacy and safety of tailored antithrombotic therapy with early (<6-month post-PCI) intensified (low-dose ticagrelor [120 mg loading, then 60 mg bid maintenance] and aspirin) and late (>6-month post-PCI) deescalated (clopidogrel alone) strategy in patients undergoing high-risk complex PCI as compared with standard Dual Antiplatelet Therapy(aspirin and clopidogrel for 12 months).

Condition Coronary Stenoses
Treatment Tailored antithrombotic strategy, Conventional antithrombotic strategy
