We evaluated the long-term outcomes of abbreviated antiplatelet therapy following PCI with third-generation DES.  \nMethods In the open-label, adjudicator-blinded, multicentre, randomised HOST-IDEA trial, 2013 patients from 37 hospitals in South Korea were randomly allocated to 3-to-6-month (n = 1002) or 12-month (n = 1011) DAPT between January 2016 and May 2021. The primary outcome was NACE at 3 years, comprising cardiac death, target vessel myocardial infarction (TVMI), clinically driven target lesion revascularisation (CD-TLR), stent thrombosis, and major bleeding (Bleeding Academic Research Consortium type 3 or 5) . Major secondary outcomes were target lesion failure (TLF)—comprising cardiac death, TVMI, and CD-TLR—and major bleeding at 3 years. To evaluate the efficacy and safety of >1-year DAPT, patients event-free at 1 year were classified into >1-year and ≤1-year DAPT groups and matched using a propensity score. These 3-year clinical outcomes were prespecified in the published protocol as mandatory clinical follow-up. HOST-IDEA is registered with [ClinicalTrials.gov](ClinicalTrials.gov), NCT02601157 .  \nFindings At 3 years, clinical follow-up was completed in 955 patients (95.3%) and 966 patients (95.5%) in the 3-to-6-month and 12-month DAPT groups, respectively. The median follow-up duration was 1095 days (IQR 1095–1095) . The primary outcome occurred in 7.7% and 8.2% of patients in the 3-to-6-month and 12-month DAPT groups, respectively (HR 0.94; 95% CI 0.69–1.29; P = 0.71) . The risks of TLF (HR 0.92; 95% CI 0.62–1.36; P = 0.66) and major bleeding (HR 0.96; 95% CI 0.59–1.56; P = 0.88) were comparable between the tw","cbCaioNRvrw6t22y","https://ap.wps.com/l/cbCaioNRvrw6t22y","pdf",660914,12,"English","# Summary\n## Background\n## Methods\n## Findings\n## Interpretation\n## Funding\n## Keywords\n## Research in context\n### Evidence before this study","[{\"question\":\"What was the main purpose of the HOST-IDEA long-term analysis?\",\"answer\":\"To evaluate long-term outcomes of abbreviated antiplatelet therapy following PCI using third-generation drug-eluting stents, extending follow-up to 3 years.\"},{\"question\":\"How were patients assigned to different DAPT durations?\",\"answer\":\"Patients in the open-label, adjudicator-blinded, multicentre randomized HOST-IDEA trial were allocated to 3-to-6-month DAPT or 12-month DAPT between January 2016 and May 2021.\"},{\"question\":\"What were the 3-year results for the primary outcome (NACE)?\",\"answer\":\"At 3 years, the primary outcome occurred in 7.7% with 3-to-6-month DAPT and 8.2% with 12-month DAPT (HR 0.94; 95% CI 0.69–1.29; P = 0.71), showing comparable outcomes.\"},{\"question\":\"Did extending DAPT beyond 1 year improve ischemic outcomes?\",\"answer\":\"Extending DAPT beyond 1 year was not associated with additional ischemic benefits, while major bleeding risk was significantly higher in the \\u003e1-year DAPT group (HR 4.44; 95% CI 1.26–15.57; P = 0.02).\"}]","Abbreviated dual antiplatelet therapy after percutaneous coronary intervention with ultrathin-strut drug-eluting stents in South Korea - 3-year outcomes of the multicentre, randomised HOST-IDEA trial | PDF",1790731892]
