They identify which blood group is most likely to have a stroke before the age of 60


The strong impact around the world of this condition of the blood circulation make stroke a general concern that continues to be studied. About 120,000 Spaniards suffer a stroke each year and half of them retain disabling sequelae or die, according to the Spanish Neurological Society. Stroke is, in fact, the second cause of death in Spain – the first among women -, the first cause of acquired disability in adults and the second cause of dementia.

Some particularly alarming data transferred to world reality has prompted the medical journal of the American Academy of Neurology to try to find out more about the origin. So it points to
genetic variants associated with a person’s blood type may be linked to early stroke risk. “Non-0 blood types have been previously associated with the risk of early stroke, but the results of our meta-analysis showed a stronger link between these blood groups with early stroke compared to late stroke, and linking the risk primarily to blood type A,” says study author D. Mitchell, a researcher at the University of Maryland School of Medicine.

16,927 people with stroke and 576,353 people without stroke from North America, Europe and Asia were studied in this meta-analysis. Of those who had a stroke, 5,825 had it earlier while 9,269 had it late, the latter being understood as those who suffer an ischemic stroke after the age of sixty. By looking at all the chromosomes, they found a link between early spillage – before age 60 – and the area of ​​the chromosome that includes the gene that determines blood type: A, AB, B or 0. So,
compared blood groups in people with early stroke, late stroke and no stroke.

Group A more likely, type 0 less risk

Following this comparative analysis, the researchers found that those who had an early stroke were more likely to have type A blood and less likely to have type 0 blood compared to those who had a late stroke. or had never had a stroke. Looking at people of European descent, the meta-analysis found that 48% of people with early stroke had type A blood, compared with 45% of people with late stroke and 44% of people without. Stroke.

People with blood type A are 16% more likely to have an early stroke

On the other hand, 35% of people with early stroke had blood type 0, compared to 39% of people with late stroke and 41% of people who did not.
