The mean PTH levels and prevalence of SHPT were significantly higher in poststroke patients compared to the rest of the cohort (despite similar mean 25(OH)D levels and even slightly lower prevalence of hypovitaminosis D), and elevated PTH levels independently predicted history of stroke when comparison was made with patients without CVD but not with all nonstroke patients among which a significant proportion had CVD. This evidence concerns the gene PTH and Stroke.
