RCT | 3-6 month DAPT noninferior to 12 month DAPT in patients undergoing PCI with third-generation DES
22 Mar, 2023 | 13:29h | UTCSummary: In a randomized trial involving 2,013 patients across 37 centers in South Korea, researchers compared the effectiveness of 3-6 month dual antiplatelet therapy (DAPT) versus 12 months of DAPT after percutaneous coronary intervention (PCI) using third-generation drug-eluting stents.
The primary outcome was net adverse clinical events (NACE), a composite of cardiac death, target vessel myocardial infarction, clinically driven target lesion revascularization, stent thrombosis, or major bleeding.
The study found that 3-6 month DAPT was non-inferior to 12-month DAPT for NACE (3.7% vs. 4.1%, respectively), with a consistent treatment effect across various subgroups. No significant differences were observed in target lesion failure or major bleeding between the two groups.
Despite these findings, further research is needed to generalize the results to other populations and to determine the ideal regimen for 3-6 month DAPT.
