According to a new study, people with blood type A have a higher risk of early stroke.
This is surprising news to say the least. According to the results of a study published in the journal Neurology, the type of blood group could play a role in the occurrence of stroke, one of the main causes of death in France. The people concerned could nevertheless reduce this grim prognosis by modifying their way of life.
Early stroke: people with blood group A are more affected
To arrive at this assertion, the researchers analyzed 48 different studies, involving nearly 16,730 people who had suffered a stroke and 599,237 people without a history of stroke. The age of the volunteers was between 18 and 59 years old.
The researchers then divided the participants by blood type (A, AB, B, and O) and compared it with each stroke category: early stroke, late stroke, and no stroke.
Results ? People with early stroke (before age 60) were more likely to be blood group A and less likely to be blood group O compared to people who had a stroke at older ages or people who did not. not having had a stroke.
Specifically, people with type A had an 18% higher risk of early stroke than those with different blood types.
Type 0 people had, conversely, 12% less risk of having an early stroke compared to other blood groups.
However, further research seems necessary to understand the link between blood type and stroke. Blood clots could be an avenue to dig, according to the authors of the study.
