PMID: 32104899. <strong>Abstract</strong> <strong>Objective: </strong> To assess the prevalence of diffuse idiopathic skeletal hyperostosis and its relationship with vascular risk factors among patients with congestive heart failure. <strong>Design: </strong> Population-based cross-sectional study. <strong>Participants: </strong> A total of 584 consecutive patients admitted to a Rehabilitative Cardiology Unit. <strong>Methods: </strong> Chi-square Automatic Interaction Detector (CHAID) decision tree analysis was used to build a predictive model. <strong>Results: </strong> The mean age (standard deviation) of the study population was 68.1 years (standard deviation 12.3), and 77.7% of the subjects were men. The overall prevalence of diffuse idiopathic skeletal hyperostosis in the cohort was 49.8%. Logistic regression analysis showed that age was a predictor of diffuse idiopathic skeletal hyperostosis (odds ratio: 1.034; 95% confidence interval 1.021-1.047, p &lt; 0.001), with increasing odds ratios for increasing age tertiles. The CHAID prediction model identified 2 age "buckets": &lt; 69 and ≥ 69 years. Patients ≥ 69 years had a diffuse idiopathic skeletal hyperostosis prevalence of 60.1%, compared with 39.2% among those &lt; 69 years. Notably, body mass index was a predictor of diffuse idiopathic skeletal hyperostosis in this younger subset of patients (p = 0.028), with 2 body mass index "buckets", ≤ 23.3 and &gt; 23.3 kg/m2, the latter showing more than twice the prevalence of diffuse idiopathic skeletal hyperostosis (43.2% vs 20%). <strong>Conclusion: </strong> Diffuse idiopathic skeletal hyperostosis is extremely frequent among patients with congestive heart failure, with age and body mass index being the strongest predictors.
