Blood type A increases early stroke risk

A new study indicates that individuals with blood type A have a 16% higher risk of experiencing an early stroke before age 60. This finding highlights a potential link between blood type and stroke susceptibility. The research, a meta-analysis of genetic studies, found that blood type O was associated with a 12% decrease in early stroke risk. The study suggests genetic and clotting factors may contribute to these differences. The study, published last week, analyzed data from nearly 17,000 people who had ischemic strokes before age 60. The findings add to the understanding of how biological factors can influence health outcomes.
