Aims The optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in patients at high bleeding risk (HBR) is still debated. The current study, using the totality of existing evidence, evaluated the impact of an abbreviated DAPT regimen in HBR patients. Methods and results A systematic review and meta-analysis was performed to search randomized clinical trials comparing abbreviated [i.e. very-short (1 month) or short (3 months)] with standard (≥6 months) DAPT in HBR patients without indication for oral anticoagulation. A total of 11 trials, including 9006 HBR patients, were included. Abbreviated DAPT reduced major or clinically relevant non-major bleeding [risk ratio (RR): 0.76, 95% confidence interval (CI): 0.61–0.94; I2 = 28%], major bleeding (RR: 0.80, 95% CI: 0.64–0.99, I2 = 0%), and cardiovascular mortality (RR: 0.79, 95% CI: 0.65–0.95, I2 = 0%) compared with standard DAPT. No difference in all-cause mortality, major adverse cardiovascular events, myocardial infarction, or stent thrombosis was observed. Results were consistent, irrespective of HBR definition and clinical presentation. Conclusion In HBR patients undergoing PCI, a 1- or 3-month abbreviated DAPT regimen was associated with lower bleeding and cardiovascular mortality, without increasing ischaemic events, compared with a ≥6-month DAPT regimen.

Multiple guidelines and consensus papers have addressed the role of antithrombotic strategies in patients with established coronary artery disease (CAD). Since evidence and terminology continue to evolve, the European Association of Percutaneous Cardiovascular Interventions (EAPCI), European Association for Acute Cardiovascular Care (ACVC) and European Association of Preventive Cardiology (EAPC) undertook a consensus initiative to guide clinicians to select the optimal antithrombotic regimen for each patient. The aim of this document is to provide an update for clinicians on best antithrombotic strategies in patients with established CAD, classifying each treatment option in relation to the number of antithrombotic drugs irrespective of whether the traditional mechanism of action is expected to mainly inhibit platelets or coagulation cascade. With the aim to reach comprehensiveness of available evidence, we systematically reviewed and performed meta-analyses by means of both direct and indirect comparisons to inform the present consensus document.

Background and Aims The impact of sex in patients with significant tricuspid regurgitation (TR) undergoing transcatheter tricuspid valve intervention (TTVI) is unknown. The aim of this study was to investigate sex-specific outcomes in patients with significant TR treated with TTVI versus medical therapy alone. Methods The TriValve (Transcatheter Tricuspid Valve Therapies) registry collected patients with significant TR from 24 centers who underwent TTVI from 2016 to 2021. A control cohort was formed by medically managed patients with ≥ severe isolated TR diagnosed in 2015-2018. Primary endpoint was freedom from all-cause mortality. Secondary endpoints were heart failure (HF) hospitalization, New York Heart Association (NYHA) functional status, and TR severity. One-year outcomes were assessed for the TriValve cohort and compared with the control cohort with the inverse probability of treatment weighting (IPTW). Results A total of 556 and 2072 patients were included from the TriValve and control groups, respectively. After TTVI, there was no difference between women and men in 1-year freedom from all-cause mortality (80.9% vs. 77.9%, p = 0.56, nor in HF hospitalization (p = 0.36), NYHA functional class III-IV (p = 0.17), and TR severity >2 + at last follow-up (p = 0.42). Multivariable Cox-regression weighted by IPTW showed an improved 1-year survival after TTVI compared to medical therapy alone in both women (adjusted hazard ratio [HR] 0.45, 95% confidence interval [CI] 0.23-0.83, p = 0.01) and men (adjusted HR 0.42, 95% CI 0.18-0.89, p = 0.03). Conclusions After TTVI in high-risk patients, there were no sex-related differences in terms of survival, HF hospitalization, functional status, and TR reduction up to 1 year. The IPTW analysis shows a survival benefit of TTVI over medical therapy alone in both women and men.
