SAPT Versus DAPT in Incomplete Revascularization After CABG (SDAT-IRC)

July 19, 2022 updated by: Antonio Nenna, MD, Campus Bio-Medico University

Single Versus Dual Antiplatelet Therapy in Patients With Incomplete Revascularization After Coronary Artery Bypass Graft Surgery

The study aims to compare the efficacy of dual antiplatelet therapy (DAPT) over single antiplatelet therapy (SAPT) in patients with incomplete revascularization after coronary artery bypass graft surgery (CABG).

Before hospital discharge, patients will be 1:1 randomized to SAPT (acetylsalicylic acid 100 mg/die) or DAPT (acetylsalicylic acid 100 mg/die + ticagrelor 90 mg bis in die). DAPT will be continued for 12 months, and ticagrelor will be withdrawn thereafter. Primary endpoint is the evaluation of cardiac-related mortality at 5 years from hospital discharge.
