Researchers find a new link between the blood group and the risk of stroke

Discover the science behind the way the two could be linked.


A cerebral vascular accident Can happen to any person at any age, but fortunately, we know a little more than that. We are aware, for example, on the well -known factors This can increase your risk of having one. These include health problems such as high blood pressure, high cholesterol, heart disease, diabetes and obesity, as well as behaviors like eating a diet rich in fats, do not do enough exercise And drink too much alcohol. But now the researchers have found a new potential risk factor for stroke: your blood group.

For a 2022 published study in the Neurology Journal, researchers from the University of Maryland School of Medicine (UMSOM) carried out a meta-analysis of data from 48 genetic studies which included around 17,000 people aged 18 to 59 who had experienced a stroke at the start of Beginning, and almost 600,000 healthy checks that had never had a race.

"Current Association Studies on the scale of the genome on ischemic strokes have mainly focused on late diseases," the researchers explained. "In addition to these studies, we have sought to identify the contribution of current genetic variants at the risk of ischemic stroke at early."

During the comparison of the two groups, they found a link between a stroke at early - which is a stroke that occurs before the age of 60 - and the chromosome area which includes the gene that determines your blood group.

"Our meta-analysis examined people's genetic profiles and found associations between the blood group and the risk of an early stroke", a study of the co-principe study Braxton D. Mitchell , PHD, professor of medicine in Umsom, said in a report . "The association of the blood group with a stroke with a subsequent appearance was much lower than what we found with an early stroke."

According to the study, those who had undergone an early stroke were more likely to have an A blood group. In fact, the researchers found that people with blood group A had a higher risk of 16% of higher Have an early stroke that people with other blood groups.

"We still do not know why the blood group has given a higher risk, but it probably has something to do with blood coagulation factors such as platelets and cells that line blood vessels as well as other circulating proteins, Who play all role in the development of blood clots " Steven J. Kittner , MD, professor of neurology in Umsom and neurologist at the University of Maryland Medical Center, said in a statement.

On the other hand, those who had undergone an early stroke were less likely to have a blood group O, which is the most common blood group. According to the study, people with blood system o have a lower risk of 12% to have a stroke than people with other blood groups.

"This study raises an important question which requires a more in -depth investigation into how our genetically predetermined blood group can play a role in the early risk of stroke" " Mark T. Gladwin , MD, executive vice-president of medical affairs at UM Baltimore, added. "This highlights the urgent need to find new ways to prevent these potentially devastating events in young adults."
