Therapy with dual antiplatelet agents, defined as the combination of a platelet P2Y12 inhibitor and aspirin, is required to prevent thrombotic complications, after percutaneous coronary intervention (PCI) with stent implantation. Usually current guidelines recommend administration of dual antiplatelet therapy (DAPT) following percutaneous revascularization with drug-eluting stent (DES) for a period of at least 12 months or for 6 to 12 months in patients not at high risk. Nevertheless, the treatment of stable/unstable coronary artery disease with DES implantation increasing largely, the optimal duration of DAPT is still unclear. The duration of DAPT after coronary stenting has been evaluated in recent randomized studies with conflicting results. The administration of long period of DAPT is a strategy to reduce thrombosis events but largely increase the hemorrhagic ones. Otherwise, shorter DAPT period is protective about bleeds with consequently increased ischemic events. In addition, as new DES carry a lower risk of stent thrombosis (ST) compared with the first-generation DES and possibly even bare-metal stents, a shift toward better protection from ST may have an effect on the duration and the intensity of DAPT. Whether the duration of DAPT should be shorter or longer than the currently recommended 6 to 12 months is analyzed in this review, drawing on results from the most recent studies and meta-analysis.
