Official title
A Prospective, Multi-center, Randomized, Double-blind Trial to Assess the Effectiveness and Safety of 12 Versus 30 Months of Dual Antiplatelet Therapy in Subjects Undergoing Percutaneous Coronary Intervention With Either Drug-eluting Stent or Bare Metal Stent Placement for the Treatment of Coronary Artery Lesions
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The DAPT Study is a double blind randomized controlled trial intended to determine the appropriate duration for dual antiplatelet therapy (the combination of aspirin and a second anti-clotting medication) as well as the safety and effectiveness of dual antiplatelet therapy to protect patients from stent thrombosis and major adverse cardiovascular and cerebrovascular events (MACCE) following the implantation of drug-eluting coronary stents. Similar analysis will be conducted in a smaller cohort of bare metal coronary stent - treated subjects.
