Tu L, et al. - Researchers examined a total of 1,262 confirmed intracerebral hemorrhage patients to determine the prognostic significance of admission serum calcium level in these subjects. Patients' medical records were inquired to obtain information on demography, medical history, medicine history, laboratory data, imaging data, clinical score, and progress note. They also reanalyzed all images of head computed tomography. They focused on 90-day prognosis, and poor outcome was defined as death or major disability caused by intracerebral hemorrhage. Based on the findings, they concluded that admission serum calcium level might be a prognostic marker for intracerebral hemorrhage. Calcium-induced coagulation function abnormality was suggested to be the potential mechanism involved.
