Abstract Cardiovascular diseases (CVDs) are a major issue in aging patients with hemophilia (PWHs). Antithrombotic agents are widely used in the general population for CVD treatment, but this recommendation is not fully applicable to PWHs. To improve treatment strategies, a prospective case–control study (COCHE) that analyzed CVD management and follow-up (2 years/patient) in PWHs was performed in France from 2011 to 2018. In total, 68 PWHs (median age: 65 years [39–89]; 48 mild, 10 moderate, Keywords and 10 severe hemophilia) were included (n ¼ 50 with acute coronary syndrome, ► antithrombotic n ¼ 17 with atrial fibrillation, n ¼ 1 with both). They were matched with 68 control treatment PWHs without antithrombotic treatment. In our series, bleeding was significantly ► atrial fibrillation influenced by (1) hemophilia severity, with a mean annualized bleeding ratio signifi- ► cardiovascular cantly higher in COCHE patients than in controls with basal clotting factor level up to disease 20%, (2) antihemorrhagic regimen (on-demand vs. prophylaxis) in severe (hazard ratio ► hemophilia [HR] ¼ 16.69 [95% confidence interval, CI: 8.2–47.26]; p < 0.0001) and moderate ► bleeding risk hemophilia (HR ¼ 42.43 [95% CI: 1.86–966.1]; p ¼ 0.0028), (3) type of antithrombotic à Benoît Guillet and Guillaume Cayla contributed equally to the present work. received DOI https://doi.org/ © 2020.

Gastrointestinal bleeding was also significantly higher in COCHE patients than in controls (OR ¼ 15 [95% CI: 1.84–268]; p ¼ 0.0141). The COCHE study confirmed that antithrombotic treat- ments in PWHs are associated with increased bleeding rates in function of hemophilia- specific factors and also of known factors in the general population.
