Abstract

PURPOSE: Previous retrospective claims database analyses reported increased prevalence and earlier onset of cardiovascular comorbidities in patients with versus without hemophilia A. A comprehensive chart review was designed to further investigate previous findings.

METHODS: This retrospective chart review study was conducted at Henry Ford Health System (Detroit, MI, USA). Baseline demographics, bleeding events, treatment parameters, coexisting diseases, hemophilia-associated events, Charlson Comorbidity Index score, and prevalence of 12 cardiovascular risk factors and associated diseases were compared between hemophilia A and control cohorts. P values from a chi-square test for categorical variables and a t test for continuous variables were calculated. Because of small sample sizes (N = 0-90, most <50), statistical differences between cohorts were also assessed using absolute standardized difference.

RESULTS: Both groups were well matched by age, race, healthcare payer, and study year. The Charlson Comorbidity Index score was similar between groups. Prevalence of bleeds, hepatitis B and C, and HIV/AIDS was higher in the hemophilia cohort. Hemophilia A severity was severe, moderate, mild, or unknown in 52.7%, 10.8%, 10.8%, and 25.7% of patients, respectively. Prevalence of 12 cardiovascular risk factors and diseases was numerically higher in the control cohort, but differences were statistically significant (P ≤ 0.05) only for diabetes and hyperlipidemia. Meaningful statistical differences using standardized differences were not reached for venous and arterial thrombosis and atrial fibrillation.

CONCLUSIONS: This retrospective chart review did not confirm statistically significant differences in cardiovascular comorbidities and their earlier onset in hemophilia A versus controls. Results suggest numerically higher comorbidities in controls.
