Research published in the journal Neurology establishes a link between a person's blood type and risk of early stroke. Among the benefits of the study are the new ways to develop stroke prevention measures in adults up to 59 years.

The characterization of blood types consists of the variety of chemicals located on the surface of red blood cells. The most common are types A and B, which can be together, as in type AB, or separately.
According to the search, entitled “Contribution of common genetic variants to the risk of stroke early ischemic stroke”, after comparing the different blood types, it was concluded that people with blood type A are more prone to the risk of early stroke before the age of 60.
Because this was a genetic study, the researchers found an explicit relationship between the gene for the A1 blood group and the risk of early stroke.
In all, about 48 genetic studies were carried out, with the presence of approximately 600 thousand people. Of that number, 17,000 patients were diagnosed with early stroke. Age ranges from 18 to 59 years.
Scientists still don't know why type A blood has a higher risk of early stroke
After finding that people with blood type A are more likely to suffer from early stroke, Scientists still can't figure out why type A blood has a higher risk of stroke precocious.
Among the assumptions are blood clotting factors, such as platelets and the cells responsible for lining blood vessels. blood, or other circulating proteins, which play an important role in the cardiovascular system and clot formation blood.
According to research by Steven Kittner of the University of Maryland, people with blood type A have 16% greater risk of having a stroke before age 60 compared to people of other types blood.
