This blood group is at high risk of stroke at a young age

JAKARTA – Recent studies found blood group it can predict whether you are at risk for experimenting stroke soon. When an ischemic stroke occurs, the blood supply to parts of the brain is cut off or reduced, which prevents the brain tissue from getting oxygen and nutrients.

This can cause brain cells to die within minutes. These findings may help develop new ways to predict and prevent stroke in young adults. The findings are published in Neurology.

Reporting by the Times of India, on Thursday (5/1/2023) researchers reviewed 48 studies on genetics and ischemic stroke from North America, Europe and Asia. This included 16,927 people with a stroke and 576,353 people who hadn’t had a stroke.

Of those who had a stroke, 5,825 had an early stroke, which is defined as an ischemic stroke that occurred before age 60. 9,269 people had a late stroke, which occurred when the patient was over 60 years old.

Compared with those with other blood types, the researchers found that those with blood type A were more likely to suffer a stroke before age 60. The researchers note that the genes for subgroup A1 and early stroke have been explicitly linked by genomic studies.

“We still don’t know why blood type A would give us a higher risk. But it could have something to do with blood clotting factors such as platelets and the cells lining blood vessels, as well as other circulating proteins, which play all play a role in the development of blood clots,” said senior author and vascular neurologist Steven Kittner of the University of Maryland.

“Notably, our meta-analysis shows that gene variants associated with blood types A and O account for nearly everything genetically linked to early stroke. People with variants of this gene may be more likely to develop blood clots, which can lead to strokes,” added study author Braxton D. Mitchell, PhD, MPH, of the University of Maryland School of Medicine in Baltimore.

The researchers also noted that those with blood type O had a 12 percent lower risk of stroke than people with other blood types.

The researchers found that people whose genomes encoded for a blood type A variation had a 16 percent higher risk of stroke before age 60, compared with populations with other blood types.

However, the researchers said the higher risk of stroke among those with blood type A was minimal, so there was no need for additional screening or monitoring.
