The risk of stroke is attached with the type of blood, with women and men having type AB and women with type B face a higher risk of stroke in comparison to people with type O, proposes a novel study. The type O has been associated with increased risk of bleeding.
Researchers from Harvard’s Brigham and Women’s Hospital carried out two surveillance studies involving nearly ninety thousand men and women and the studies gone for more than twenty years. While, investigating nearly three thousand cases of strokes which have occurred during the study period, researchers considered aspects such as blood pressure and other stroke risk.
They found men and women with type AB had twenty-six percent greater risk of stroke in comparison to men and women with type O and that women with type B had fifteen percent higher risk of stroke than women with type O. Type of blood in human body depends upon the proteins present on the surface of red blood cells.
The structure of immune system reactions figures early in life is based on them. There is mounting evidence that blood type might persuade risk of chronic disease, explained the study leaders, Dr. JoAnn Manson, chief of preventive medicine at Harvard’s Brigham and Women’s Hospital. Certain blood types appear to make red cells more likely to bundle together and stick to the lining of blood vessels.
They set the stage for a clot, one more element of risk people would want to know, which could encourage them to keep watch on their blood pressure and cholesterol, she added. You cannot change it, and it is not known if it is the blood type or other genes track with it actually confers risk, stated Dr. Larry Goldstein, director of Duke University’s stroke center.
He added there are other things that are more significant than blood type for stroke risk, such as smoking, drinking too much and exercising too little. According to the American Red Cross, about forty-five percent of white people, fifty-one percent of blacks, fifty-seven percent and forty percent of Asian have blood type O.
People with type O are called as universal donors as their blood can be used safely for transfusions to people with any other blood type. AB blood is the least common type and this type is present in four percent of whites and blacks, two percent of Hispanics and seven percent of Asians. B is the second least common overall.
