Kitamura M, et al. - In this cross-sectional case-control study, researchers examined the link between serum calcium and cerebral hemorrhage in patients on hemodialysis (HD), including in-hospital mortality, volume of hematoma, and onset of cerebral hemorrhage. This study included 99 patients, of those, deaths due to cerebral hemorrhage were reported in 32 (32%). The prognosis was significantly influenced by the corrected serum calcium level and antiplatelet drug use. Moreover, a significant correlation of the corrected serum calcium and antiplatelet drug use, with hematoma volume, was reported. Overall, findings revealed a link between high serum calcium level and cerebral hemorrhage in patients on HD, although the precise mechanisms are not known. Therefore, a patient’s calcium level deserves attentions.
