Cardiovascular comorbidities are increased in US patients with haemophilia A: a retrospective database analysis

This study evaluated the prevalence of cardiovascular comorbidities among USA males with haemophilia A, relative to an unaffected general male population with similar characteristics. Males with haemophilia A and continuous insurance coverage were identified by ICD‐9‐CM code 286.0 (1 January 2007–31 December 2009) using the MarketScan® Commercial and Medicare Research Databases. Individuals with haemophilia A were exact matched 1:3 with males without a diagnosis of haemophilia A. The prevalence of cardiovascular comorbidities identified by ICD‐9‐CM code was determined for matched cohorts. Of the study population, 2506 were grouped in the haemophilia A cohort and 7518 in the general cohort. Proportions of individuals with haemorrhagic stroke (2.0% vs. 0.5%, P < 0.001), ischemic stroke (4.7% vs. 2.7%, P < 0.001), coronary artery disease (10.7% vs. 5.8%, P < 0.001), myocardial infarction (0.8% vs. 0.3%, P = 0.003), hypertension (22.6% vs. 15.5%, P < 0.001), hyperlipidaemia (15.9% vs. 11.9%, P < 0.001), arterial thrombosis (12.1% vs. 5.9%, P < 0.001), and venous thrombosis (4.4% vs. 1.1%, P < 0.001) were significantly greater for the haemophilia A cohort. Results were consistent across most age groups, and comorbidities appeared at an earlier age in those with haemophilia A than in the general population. Among the USA haemophilia A population cardiovascular comorbidities are more prevalent and they appear earlier in life in comparison...
