This is the blood group that is at risk for heart disease

KONTAN.CO.ID – JAKARTA. Research shows that a person’s blood type can affect the risk of heart disease. In one study, people with blood types A, B, and AB were more likely to develop heart disease than people with blood types O.

The study’s senior author is Lu Qi, an assistant professor in the Department of Nutrition at the Harvard School of Public Health in Boston. He and his colleagues report their findings in a paper published online in one of the journals of the American Heart Association.

Researchers analyzed data from two large studies of adults for at least 20 years and found that those with blood type AB had a 23 percent increased risk of heart disease.

In addition, those with type B had an 11 percent increased risk and those with type A had a 5 percent increased risk, compared to people with type O.

Researchers don’t yet know why blood type affects heart disease risk, but evidence from other studies provides some clues.

Type A blood is associated with higher levels of low-density lipoprotein (LDL) cholesterol, or artery-clogging “bad” cholesterol. Type AB blood is linked to inflammation, which can affect how blood vessels work.

Meanwhile, people with blood type O have high levels of certain compounds that have beneficial effects on blood flow and clotting.
