Aspirin plus clopidogrel therapy is the conventional DAPT protocol. In patients undergoing coronary artery bypass grafting (CABG), dual antiplatelet therapy (DAPT) with ticagrelor or clopidogrel is superior to aspirin alone for preventing saphenous vein graft failure, according to a meta-analysis in The BMJ.. s.parentNode.insertBefore(b, s);})(); 18 .Volume–outcome relationship for revascularization procedures. With evidence of single drug resistance and variable degree of biotransformation, there is a strong ground for the routine use of DAPT after CABG.
