ORDEN, Alberto O. et al. Association of diffuse idiopathic skeletal hyperostosis and aortic valve sclerosis. Medicina (B. Aires) [online]. 2014, vol.74, n.3, pp.205-209. ISSN 0025-7680.

The principal objective of this investigation was to analyze the association between diffuse idiopathic skeletal hyperostosis (DISH) and the presence of aortic valve sclerosis (AVS). For this study we used results from 1000 consecutive outpatients (473 males), older than 50 years of age (average 67.6 years), that had been examined with Doppler echocardiogram and anterior and lateral chest radiographs. Overall, 195 patients (19.5%) were diagnosed with DISH and 283 (28.3%) with AVS. DISH was more prevalent than AVS in males (66.7% vs. 42.6%, p< 0.0001) and in older patients (73.6 ± 9 years vs. 66.1 ± 9 years, p < 0.0001). Furthermore, 55.4% of patients with dorsal DISH presented aortic sclerosis calcification vs. 21.7% of patients free of DISH (OR = 4.47; 95% CI = 3.22-6.21). The adjusted odds ratio (OR) was calculated by sex and age resulting in 3.04 (95% CI = 2.12-4.36; p < .0001). A statistically significant association was found between DISH and AVS in accordance to age and sex. The biological plausibility of this association is based on similar risk factors, pathogenic mechanisms and vascular complications.
