Supporting evidence from optical coherence tomography for shortening dual antiplatelet therapy after drug-eluting stents implantation. [Review] - 2020

Introduction: Dual antiplatelet therapy (DAPT) is required for coronary artery disease treated with drug-eluting stents (DES) implantation. Shortening DAPT duration would be beneficial for patients with high bleeding risk. Areas covered: Early healing patterns, especially stent strut coverage, assessed by optical coherence tomography (OCT) as a surrogate of neointima have been investigated to make decisions on whether short DAPT would be a safe alternative. This review evaluates the OCT evidence (i.e. neointimal coverage of stent struts within 3 months) for shortening DAPT duration after DES implantation. Expert commentary: Shortening DAPT (i.e. within 3 months) duration after DES implantation might reduce complications including bleeding without increasing stent thrombosis. However, the optimal duration of DAPT after DES implantation is under discussion. Long-term assessment of short DAPT is required for the decision of the new guidelines regarding the recommended duration of DAPT.
