Summary.  The primary objective of the study was to examine the prevalence of cardiovascular disease (CVD) events and their known risk factors among persons with haemophilia (PWH). This cross-sectional study, covering a 5-year period, included PWH aged ≥35 years who were cared for at a single haemophilia treatment centre in the United States. Medical records were extensively reviewed to collect the information about CVD events and their risk factors such as obesity, hypertension, diabetes, hypercholesterolemia and smoking. Prevalence rates were compared with national population estimates and associations between risk factors and CVD events were examined using logistic regression. The study cohort comprised 185 PWH (102 haemophilia A and 83 haemophilia B). Lifetime prevalence of a CVD event was 19.5% (36/185, 95% confidence interval [CI] 13.8–25.2%). CVD mortality was 5.4% (10/185, 95% CI 2.7–8.1). Compared with US non-Hispanic White males (NHWH), PWH had about twice the prevalence of coronary artery disease, stroke and myocardial infarction. The prevalence of CVD risk factors for PWH was similar to that for US NHWM with 39.5% of PWH exposed to two or more of these risk factors. Both hypertension and smoking were associated significantly with CVD events, with odds ratios of 4.9 and 6.3, respectively. In conclusion, this study revealed that both CVD events and its risk factors were at least equally prevalent among PWH and might have been even higher than among the US NHWM in the United States. Therefore, it is imperative to implement strategies for CVD prevention among PWH.
