"Link Between Blood Type and Early Stroke Risk Uncovered by Researchers"
Scientists have discovered that individuals with type A blood have a 16% higher risk of experiencing a stroke before age 60 compared to those with other blood types. Conversely, those with type O blood have a 12% lower risk. The study, which analyzed data from 48 genetic studies involving over 17,000 stroke patients and 600,000 controls, found that the increased risk is associated with genetic variations in the A1 blood type subgroup. However, the risk of stroke associated with blood type becomes insignificant in those who have a stroke after age 60, indicating different mechanisms may be at play in early versus late-onset strokes. The research, published in the journal Neurology, suggests that blood type may influence stroke risk through factors related to blood clotting.
