title: [Correlation of ABO groups to hypertensive intracerebral hemorrhage].
abstract: OBJECTIVE
  To study the relationship between ABO blood groups and hypertensive intracerebral hemorrhage (HICH).
  
  
  METHODS
  The clinical data of 425 patients with HICH admitted to Nanfang Hospital were collected to analyze the relationship between the ABO blood groups and the occurrence of HICH, with normal Han Chinese subjects serving as the controls.
  
  
  RESULTS
  Compared to the officially documented distribution of ABO groups in Chinese population (O 34.11%, B 28.98%, A 28.29%, AB 8.69%) and in Guangzhou residents (O 46.00%, B 25.00%, A 23.00%, AB 6.00%), a significant difference was noted in the blood group distribution in this cohort (O 45.10%, A 26.00%, B 24.00%, AB 4.90%). O blood type individuals with HICH showed a higher morbidity than others. Th ABO blood type distribution in this cohort showed no significant difference from that in the control group (P>0.05), but differed significantly from the Chinese norm (P<0.05).
  
  
  CONCLUSIONS
  The ABO blood group is a factor contributing to the occurrence of HICH. O blood type is related to cerebral hemorrhage, and may serve as a risk factor for HICH.
