Individuals with cerebral palsy (CP) have poor skeletal and cardiovascular health. However, no studies have examined if skeletal fragility enhances cardiovascular disease (CVD) risk for this population. The purpose of this study was to determine whether adults with CP have higher 12-month CVD incidence following a low-trauma fracture compared with adults without CP. Data, from the Optum Clinformatics® Data Mart, were extracted from adults (18+ years) that sustained a low-trauma fracture between 01/01/2012 and 12/31/2016. The primary outcome measure was incident CVD within 12 months following a low-trauma fracture. Cox proportional hazards regression models were used to compare 12-month incident CVD with adjustment for sociodemographics and chronic disease comorbidities. Mean age (SD) at baseline was 54.7 (18.9) for adults with CP (n = 1,025, 43.3% men) and 60.4 (19.7) for adults without CP (n = 460,504, 33.7% men). During the follow-up, 121 adults with CP (11.8%, mean age [SD] = 63.9 [16.3]) and 45,330 adults without CP (9.8%, mean age [SD] = 74.5 [11.9]) developed CVD. In the fully adjusted model, adults with CP had higher 12-month post-fracture CVD incidence (hazard ratio [HR] = 1.63; 95% confidence interval [CI] = 1.37-1.95). When the outcome was stratified by CVD subtype, adults with CP had higher 12-month post-fracture incidence of ischemic heart disease (HR = 1.45; 95% CI = 1.09-1.92), heart failure (HR = 1.68; 95% CI = 1.22-2.31), and cerebrovascular disease (HR = 1.96; 95% CI = 1.54-2.50). Study findings suggest that among adults with CP, low-trauma fracture may enhance 12-month CVD incidence compared with adults without CP. © 2019 Orthopaedic Research Society.
