Study Shows Blood Group O Increase Death Risk From Traumatic Injury

A new study has found that having type O blood could almost treble the risk of passing away from severe injuries. As believed by the researchers, the blood group is linked to low levels of a coagulating agent that might cause greater bleeding.

Records from 901 emergency care individuals in Japan established 28% death rate for individuals with type O blood. On the other hand, the death rate of individuals from other blood groups collectively was 11%. Dr Wataru Takayama, the lead researcher of the Tokyo Medical and Dental University Hospital, stated, “Recent studies propose that blood type O can be a latent risk factor for hemorrhage.”

Dr Takayama continued, “Loss of blood is the major reason for death in individuals with severe trauma; however, studies on the connection between diverse blood types and the possibility of trauma death have been sparse. We intended to assess the theory that trauma survival is influenced by distinctions in blood types.”

Throughout the UK population, 47% is type O, thus making it the ordinary blood group. The blood type is evaluated by proteins on the facades of red blood cells. AB, A, and B are other major categories of the blood group. Type O blood can usually be given to anyone with no side-effects.

Nevertheless, individuals with type O blood have low Von Willebrand factor levels, which is a blood coagulating agent that might assist to put off life-threatening bleeding. The findings raised queries regarding the urgent situation transfusion of type O red blood cells to serious trauma patients—sufferers of injuries with the probability to cause death or long-term disability, said Dr Takayama.

A 2012 study by the Harvard University researchers established that individuals with non-O blood as well happen to have an elevated threat of cardiovascular disease. However, those with type AB blood were, on the whole, the most at-risk, showing a 23% more possibility of having heart disease compared top type O individuals.
