Associations between DAPT score and long-term mortality post PCI

Abstract Introduction The dual antiplatelet therapy (DAPT) score was developed to identify patients more likely derive benefit (score ≥2) or harm <2) from DAPT beyond 1-year post PCI. There is no study which looked at the and long term outcomes PCI in Australia. Purpose We sought examine long-term mortality after by treated with per local guidelines. Methods examined data MIG database 2005 2018 whom could be derived grouped them as ≥2 <2. Long-term assessed National Death Index linkage. primary endpoint using survival analysis. Secondary endpoints included 30-day ischaemic in-hospital major bleeding. Results Out of 27,740 study, 9,401 (33.9%) had ≥2. They were younger females higher prevalence renal impairment. bleeding, mortality, MI target vessel revascularisation. lower 12 years (p<0.001 for all). Conclusion A third all-comer greater short-term risk bleeding outcomes, well mortality. Theoretically, those would longer duration outweighs risk. However, given our finding increased dynamic assessment should undertaken guide pharmacotherapy strategies. Funding Acknowledgement Type funding sources: None.
