People with this blood type are 16% more likely to have a stroke before the age 60

Researchers at the University of Maryland (UMD) found that people with type A blood are more likely to experience an early-onset ischemic stroke — caused by a blockage of blood flow to the brain — while those with blood type O have a lower risk.

“The number of people with early strokes is rising,” said Dr. Steven J. Kittner, co-principal investigator of the study and neurologist with the UMD Medical Center. “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.”

In a 2022 analysis, Kittner and his colleagues sifted through data from 48 genetic studies, involving 17,000 stroke patients and nearly 600,000 healthy individuals who had never suffered a stroke. All participants were between 18 and 59 years old. After reviewing their genetic profiles, researchers discovered a potential link between early strokes and the part of the chromosome that contains the gene determining whether your blood type is A, AB, B or O.

Interesting. I’ll never donate, however. Really squeamish about even looking at blood. If my MD ever had to draw blood, I’d look the other way.
