A large -scale study with the participation of 617 thousand people has shown that a blood group could affect the risk of early stroke. In addition, people with blood group A (II) have 16% higher risk of stroke under the age of 60. At the same time, the owners of the group O (I) , on the contrary, have 12% lower risk .
In a study published in 2022, the Geneomists found a clear relationship between the genome of subgroup A and the early onset of stroke. They collected data from 48 genetic studies, which were attended by about 17,000 strokes and almost 600,000 people without stroke. The participants were 18 to 59 years old.
Analysis of specific types of blood group genes has shown that people whose group A have 16% higher risk of stroke under 60 years of age compared to people with other blood groups.
For those who have a group O (s), the risk is lower by 12%.
We still do not know why blood group A increases the risk of stroke. But this is probably due to blood coagulation factors, as well as other circulating proteins that play a role in the formation of blood clots
Kittner believes that further research is needed to clarify the mechanism of increased risk of stroke.
Another key conclusion of the study was obtained as a result of comparing people who have suffered a stroke under the age of 60, with those who have suffered a stroke after the age of 60.
Found that increased risk of stroke in people with the first blood group became insignificant in a group of late strokes. This indicates that strokes that occur at the beginning of life may have a different mechanism than strokes that occur at a later age.
According to the authors, strokes in young people are less likely to cause the accumulation of fat deposits in the arteries (atherosclerosis) and are more commonly caused by factors associated with the formation of blood clots.
The study also found that people with blood group in (III) have about 11% more likely to get stroke.
According to Heathline, regular use of dental filament can reduce the risk of stroke and atrial fibrillation (AFIB). People who use it constantly have 22% less risk of ischemic stroke and 44% lower probability of cardio -embolic stroke. Scientists suggest that the care of the oral cavity reduces inflammation that affects the heart and blood vessels.
