As per a new study, blood type might be associated with one’s risk of experiencing an early stroke.

This new finding should hopefully pave the way for more effective medicine that can prevent young people from experiencing this serious health problem.

That being said, you should know that blood types refer to the chemicals on the surface of red blood cells and, as the name also suggests, there are several different types.

Some of the most common are A and B, which can also be grouped together as AB or found separately as A or B.

Characterized by their absence is the O type.

As it turns out, those that have type A blood are more likely to suffer a stroke before the age of 60 when compared to those that have other blood types.

This and more is what the study titled ‘Contribution of Common Genetic Variants to Risk of Early Onset Ischemic Stroke’ and published in Neurology stated.

The research team gathered information from 48 different genetic studies that featured around 600,000 non-stroke controls as well as around 17,000 individuals who had suffered strokes.

The participants’ ages ranged from 18 to 59 years old.

In the study, the researchers were able to find two regions highly linked to an early stroke risk.

One of them matched the blood type genes’ location.

More precisely, in the second analysis of specific blood type genes, the patients whose genomes coded for a variation of A type group were found to have a 16 percent higher risk of suffering a stroke before the age of 60 when compared to people with other blood types.

Furthermore, people who carried the blood group O1 gene presented a 12 percent lower risk of suffering an early stroke.

At the same time, it’s important to note that there is no need for additional monitoring or screening in the case of those with type A blood type.

The researchers explain that this is because the higher risk is actually quite minimal.

Steven Kittner, the senior author of the study, says that “We still do not know why type A would confer a higher risk. It likely has something to do with blood clotting factors such as platelets and cells which line the blood vessels and other proteins, all of which play a role in developing blood clots.”
