Your Blood Type May Predict Your Risk Of Having A Stroke Before 60: Study

2 min read


According to recent research, a person’s blood type may affect their chance of getting an early stroke. The results might open new avenues for stroke prediction and prevention in young adults.

The various substances on the surface of our red blood cells are called blood kinds. The most prevalent pair is A and B, which can show up as AB, A, or B, or not at all as O. According to the study, people with type A blood are more likely than people with other blood types to have a stroke before they are 60. Genomic research has demonstrated a relationship between the A1 subgroup gene and early-onset stroke. Forty-eight genetic studies, including over 600,000 non-stroke controls and 17,000 stroke patients, were the source of the data that the researchers acquired. All participants were between the ages of 18 and 59.

Two areas were significantly associated with stroke risk in its early stages. One was in the same place as the blood type genes. The second investigation of individual blood-type genes found that, compared to a population with other blood types, people whose genomes coded for a variation of the A blood group had a 16% increased chance of having a stroke before age 60.

A 13% decreased risk was associated with blood group O1 gene carriers. There is no requirement for additional screening or monitoring because the researchers found that the increased risk of stroke among people with type A blood is low.

“We still don’t know why blood type A would confer a higher risk. But it likely has something to do with blood-clotting factors like platelets and cells that line the blood vessels as well as other circulating proteins, all of which play a role in the development of blood clots,” said senior author and vascular neurologist Steven Kittner from the University of Maryland.
