The research doesn’t prove the correlate. But it fits with other studies that have knotted A, B, and AB to center bombard and to blood clots in the thighs. And type O has been linked to a accentuated risk for bleeding, which implies less accident of the clots that are responsible as most strokes.
There’s increasing testify that blood type might affect hazard of chronic ailment,” said one of the study governors, Dr. JoAnn Manson, central of preventive medication at Harvard’s Brigham and Women’s Hospital. “It’s no at the level where we ambition to fear people and we want to make that explicit. But it’s 1 more element of risk namely people would want to understand approximately,” and it could encourage them to keep see ashore their keep blood oppression and cholesterol, she said.
The study was led at Brigham’s Dr. Lu Qi and was presented Wednesday at a conference of the American Heart Association. It comprised 90,000 men and women in two observational studies that have worked on for more than 2 decades.
Looking at the 2,901 strokes that have happened during that time and taking tall blood pressure and additional stroke risk factors into list, researchers found that men and women with AB had a 26 percent higher risk of stroke compared to those with type O and that women with type B blood had a 15 percentage greater risk likened to women with type O.
Blood type depends on proteins on the surface of ruddy blood compartments. A pattern of immune system responses forms early in life based on them. Certain blood types appear to make red cells more probable to clump attach and stick to the lining of blood vessels, setting the stage for a clot, Manson said.
You can’t alteration it, and we don’t know if it’s the blood type per se or other genes that trace with it” that really confers risk, said Dr. Larry Goldstein, adviser of Duke University’s stroke hub. “There are other things that are more major” than blood type for stroke risk, such for smoking, drinking too many and exercising also tiny, he said.
