Your blood type may give essential clue to heart disease risk
Dallas: Do you know your blood group? If no, then here’s another reason why you should know your blood type as soon as possible.

According to a study conducted by Harvard School of Public Health in Boston, your blood type may provide the essential clue if you are prone to any heart disease risk.


People who have blood types A, B, or AB have a slightly higher risk of heart disease compared to those with type O, the most common kind, according to research released on Tuesday.

Dr Lu Qi, senior author of the study was quoted saying to a news agency that “Those who know they are at higher risk may be more motivated to make changes to lower their chances of heart disease”.

“We cannot change blood type but we can change lifestyle,” added Qi, who led a study released last year that showed blood type may affect stroke risk.

The new study involved about 90,000 men and women in two observational health studies that cover more than 20 years. Combined, 4,070 people developed heart disease.
The researchers considered age and other factors like diet, drinking, family history of heart attacks that could contribute to heart disease.

The increased risk for type A was 8 percent; type B, 11 percent; and type AB, 20 per cent.

While the study did not examine how blood type may affect heart disease risk, it noted that research has shown some characteristics of different types may be a factor. For instance, some research suggests that blood types might affect cholesterol levels or the risk of developing blood clots.

The findings were published in the American Heart Association journal Arteriosclerosis, Thrombosis and Vascular Biology.

No matter what blood type, Harvard`s Qi said everyone should pay attention to risk factors they can change, including smoking, weight, high cholesterol, high blood pressure and a sedentary lifestyle.

Type O is the most common blood type, followed by A, B and AB. About 45 percent of whites, 51 percent of blacks, 57 percent of Hispanics and 40 per cent of Asians have blood type O, according to the American Red Cross.

Type A: 40 percent of whites, 26 percent of blacks, 31 per cent of Hispanics and 28 per cent of Asians.

Type B: 11 percent of whites, 19 percent of blacks, 10 percent of Hispanics and 25 per cent of Asians.

Type AB: 4 percent of white and blacks, 2 percent of Hispanics and 7 percent of Asians.
