In Colombia, about 50% of the population belongs to blood group O.
Strokes, also known as brain attacks or strokes, occur when blood flow to part of the brain stops. According to MedlinePlus, a service of the US National Library of Medicine, there are two types of stroke. (Can read: A little stress could be key to a healthy old age)
The first of these, the most common with 80% of cases, is known as ischemic and is caused by a blood clot that blocks a blood vessel in the brain. The second type, hemorrhagic, occurs when a blood vessel ruptures and bleeds into the brain.
Now, an investigation reveals that a person’s blood group may be related to the risk of suffering an early or early stroke, that is, one that occurs before the age of 60. The research, carried out by researchers at the University of Maryland School of Medicine (United States), conducted a meta-analysis of 48 studies, which included nearly 17,000 patients who had suffered an accident of this type and another 600,000 who never they had suffered a stroke.

According to Steven Kittner, one of the study’s lead authors and a professor at the University of Maryland, “The number of people with early strokes is increasing. These people are more likely to die from this life-threatening event, with survivors potentially facing decades of disability. Despite this, the causes of early strokes have hardly been investigated”.
For this reason, a team of researchers led by him analyzed the collected chromosomes to help identify genetic variants associated with a stroke. What they found was that there is a relationship between the area of the chromosome that includes the gene that determines blood group and an early stroke.

In other words, this means that the risk of having a seizure of this type varies according to whether a person has blood type A, AB, B, or O. In fact, they found that people with blood type A had a 16% higher risk of having an early stroke than people with other blood types.
Meanwhile, those with blood group O have a 12% lower risk of stroke than people with other blood groups. “We don’t yet know why blood group A confers a higher risk, but it likely has something to do with blood clotting factors, such as platelets and cells lining blood vessels, as well as other circulating proteins. , all of which play a role in the development of blood clots,” said researcher Kittner.

Despite the findings, the researchers cautioned that the increased risk is modest, so people with type A blood should not worry about having an early stroke or undergoing medical tests other than conventional ones. The scientists also added that more studies are needed that include a population with greater population variation.
