title: Factors associated with in-hospital mortality following intracerebral hemorrhage: a three-year study in Tehran, Iran.
abstract: BACKGROUND
  Primary intracerebral hemorrhage (ICH) is one of the common vascular insults with a relatively high rate of mortality. The aim of the current study was to determine the mortality rate and to evaluate the influence of various factors on the mortality of patients with intracerebral hemorrhage (ICH). Demographic characteristics along with clinical features and neuroimaging information on 122 patients with primary ICH admitted to Sina Hospital between 1999-2002 were assessed by multivariate analysis.
  
  
  RESULTS
  Of 122 patients diagnosed with intracerebral hemorrhage, 70 were men and 52 were women. Sixty-nine percent of subjects were between 60 to 80 years of age. A history of hypertension was the primary cause in 67.2% of participants and it was found more frequent compared to other cardiovascular risk factors such as a history of ischemic heart disease (17.2%), diabetes mellitus (18%) and cigarette smoking (13.1%). The overall mortality rate among ICH patients admitted to the hospital was 46.7%. About one third of the deaths occurred within the first two days after brain injury. Factor independently associated with in-hospital mortality were Glasgow Coma Scale (GCS) score (</= 8), diabetes mellitus disease, volume of hematoma and and intraventricular hematoma.
  
  
  CONCLUSIONS
  Higher rate of mortality were observed during the first two weeks of hospitalization following ICH. Neuroimaging features along with GCS score can help the clinicians in developing their prognosis.
