Cardiovascular risk factors among adult patients with haemophilia

Since the introduction of episodic and prophylactic treatments with safer factor concentrates, the life expectancy of people with haemophilia (PwH) has improved considerably. Ageing-related diseases such as cardiovascular disease (CVD) have also become more prevalent in PwH. This cross-sectional study aimed to evaluate CVD risk factors and estimate 10-year risk for CVD events among PwH. Male patients ≥ 30 years were interviewed and examined. Blood tests were performed at the local laboratory. Eighty-two patients were included, of whom 83% had haemophilia A and half had severe disease. Median age at study entry was 43.0 years (interquartile range [IQR], 36.0-51.3). Prevalence of obesity, systemic arterial hypertension (SAH) and diabetes mellitus were 16%, 60% and 16%, respectively. Hypertriglyceridaemia, hypercholesterolaemia and low HDL blood levels were present in 18%, 41% and 30% of patients, respectively. Metabolic syndrome was found in 37%. The Framingham Risk Score showed that 39% of PwH had a high risk of developing cardiovascular events in the following 10 years. We conclude that, in this cohort, PwH have a higher prevalence of SAH when compared with Brazilian men without haemophilia and about two-fifths have a high risk of developing a CVD event in the following 10 years.
