Here’s another reason to know your blood type — it might be a clue to your risk of heart disease.
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.
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, but 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 percent.
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.
No matter what blood type, everyone should pay attention to risk factors they can change, including smoking, weight, high cholesterol, high blood pressure and a sedentary lifestyle.
