Study: Blood type affects the risk of premature stroke

Research has shown that people with type A blood are more likely to have a stroke before the age of 60 than people with other blood types.
In a study published last year, genome researchers uncovered a clear link between the A1 subset gene and early stroke.
The researchers pooled data from 48 genetic studies, which included nearly 17,000 people who had had a stroke, and nearly 600,000 people without a stroke. All participants ranged in age from 18 to 59.
A genome-wide search revealed two spots strongly associated with pre-stroke symptoms, one of which was associated with the spot where blood type genes are located.

A second search of certain types of blood group genes found that people whose genomes were coded for and identified from the A groups had a 16 per cent higher risk of having a stroke before the age of 60, compared to other blood groups.
However, the researchers say, the additional risk of stroke in people with blood type “A” is small, and does not warrant concern or continuous examination, according to what was reported in the “Sciencealert” magazine.
“We still don’t know why type A blood poses a greater risk, but it likely has something to do with blood clotting factors such as platelets, the cells that line blood vessels, as well as blood clotting factors,” said lead researcher Stephen Kittner, a University of Maryland neurologist and vascular physician. other circulating proteins, all of which play a role in the formation of blood clots.”

“It is clear that we need more follow-up studies to elucidate the mechanisms of increased stroke risk,” Kittner added.
