Blood Type AB Most Taxable Stroke Risk


Jakarta, Stroke occurs when blood flow in the brain is interrupted. Speaking of blood, of certain blood groups were more at risk of causing a stroke than other blood types.

Dr. Joann Manson, Professor of Epidemiology at the Harvard School of Public Health who also served as division chief of Preventive Medicine at Harvard's Brigham and Women's Hospital examined the relationship between human blood groups and risk of stroke.

As reported by MedicalNewsToday.com, Sunday (12/18/2011), he made observations on more than 90,000 men and women for 20 years and found that:
1. Blood type B associated with an increased 17% risk of stroke in women, but not in men.
2. AB blood type associated with an increased 29% risk of ischemic stroke in both men and women.

Ischemic stroke caused by blockage of blood vessels in the brain. Another type of stroke is a hemorrhagic stroke, the rupture of blood vessels are weak, and transient ischemic attack (TIA) or "mini stroke" caused by temporary clot in blood vessels.

When comparing with the blood type AB blood group O, Dr. Manson discovered that the blood type AB associated with stroke risk 28% higher in women and 32% higher in men.

The differences reflect differences in blood group glycoprotein on the surface of red blood cells that will affect the immune system developments. According to Dr. Manson, these differences may affect the stiffness of red blood cells so that some types of blood clots form more easily and freezes than other blood groups.

This information should help identify the risk of stroke. People who have blood type is at risk of stroke may have other risk factors known to be more overall risk profile.

Henceforth, this information will also be useful to give advice on healthy lifestyles through an intensive exercise and nutritious food.

Dr. Manson also explained that the relationship between blood type with the risk of stroke should not be considered as a warning of danger, but it may be one reason for the importance of maintaining blood pressure and cholesterol remained within normal limits.
