Researchers believe that a person's blood type may be to blame for their chance of forming risky clots, although it is unclear why blood type is playing such a significant role in predicting the risk of stroke.
According to recent studies, blood type may be able to predict a person’s risk of suffering a stroke before age 60.
People with type A blood had a higher risk of stroke before the age of 60 than those with type O blood, according to study from the University of Maryland School of Medicine (UMSOM).
When the brain’s blood supply is cut off, a stroke occurs. This medical emergency damages the brain. A stroke can cause paralysis or numbness in the face, arm, or leg, as well as difficulties with walking, speaking, and understanding. Brain damage can be minimised with early therapy using drugs like tPA (clot buster). Other therapies concentrate on reducing side effects and averting further strokes. Treatment as soon as it happens is essential. If intervention is taken early on, brain damage and other consequences can be somewhat mitigated.
Researchers examined information from genetic studies on the most prevalent type of stroke, ischemic stroke, in the new meta-analysis, which was published in the journal Neurology.
Following study, researchers discovered that blood type A individuals have a 16% higher risk of having one stroke before the age of 60.
According to the research, people with type O blood, which is the most prevalent, had a lower risk of stroke, while people with type B blood had a slightly higher risk. The researchers noted that the elevated risk was minor and advised individuals not to be concerned. However, it is unclear why blood type is so important in determining stroke risk. However, scientists believe that a person’s blood type may play a role in their propensity to form risky clots.
The study involved the analysis of 17,000 stroke victims’ cases. 48 research on genetics and ischemic stroke were examined by Steven J. Kittner and his team. Nearly 600,000 healthy volunteers who had never suffered a stroke were also studied. The study also discovered that people with blood type O had a 12% lower risk of having a stroke before the age of 60. Types B and AB were likewise discovered to have no effect.
The study co-principal investigator Steven J Kittner, MD, MPH, Professor of Neurology at UMSOM, said, “The number of people with early strokes is rising. These people are more likely to die from the life-threatening event, and survivors potentially face decades with disability. Despite this, there is little research on the causes of early strokes.”
