Antiplatelet therapy is a very important part of medical therapy for patients after acute coronary syndrome (ACS) as well as in a stable coronary artery disease (CAD). The use of antiplatelet therapy after coronary artery bypass graft surgery (CABG) still is a controversial theme in daily clinical practice. While guidelines referring to dual antiplatelet therapy (DAPT) after ACS with proceeding percutaneous coronary intervention (PCI) are uniform, there are doubts regarding DAPT after CABG, especially in setting of chronic coronary syndrome (CCS). Recommendations are mostly based on expert opinion and not on multiple randomized controlled trials (RCT) or meta-analyses. Resistance to aspirin (acetylsalicylic acid, ASA) or other antiplatelet drugs is known after CABG, and further RCTs are needed to assess the effect on clinical outcome as well as the role of DAPT after CABG.
