A person's blood type may be linked to their risk of having an early stroke, according to a new meta-analysis. The meta-analysis included all available data from genetic studies focusing on ischemic strokes, which are caused by a blockage of blood flow to the brain, occurring in younger adults under age 60.
Steven J. Kittner, MD, MPH and his colleagues conducted the study by performing a meta-analysis of 48 studies on genetics and ischemic stroke that included 17,000 stroke patients and nearly 600,000 healthy controls who never had experienced a stroke. They then looked across all collected chromosomes to identify genetic variants associated with a stroke and found a link between early-onset stroke—occurring before age 60—and the area of the chromosome that includes the gene that determines whether a blood type is A, AB, B, or O.
The study found that people with early stroke were more likely to have blood type A and less likely to have blood type O (the most common blood type)—compared to people with late stroke and people who never had a stroke. Both early and late stroke were also more likely to have blood type B compared to controls. After adjusting for sex and other factors, researchers found those who had blood type A had an 16 percent higher risk of having an early stroke than people with other blood types. Those who had blood type O had a 12 percent lower risk of having a stroke than people with other blood types.
The researchers emphasized that the increased risk was very modest.
Previous studies suggest that those with an A blood type have a slightly higher risk of developing blood clots in the legs known as deep vein thrombosis.
