The researchers looked at two studies that follow nearly 90 thousand people for over 20 years. The conclusions of that study, the risk of CHD varies depending on the blood group.
People with blood type O have the lowest risk, while blood type AB have 23% more likely to be affected by CHD. In the meantime, blood type B + 11%, while blood type A is only 5%.
Because people are unlikely to change their blood type, our findings might help physicians to better understand anyone who is at risk of getting heart disease, said the owner of the research, Dr. Lu Qi, Assistant Professor of nutrition at the Harvard School of Public Health in Boston.
The researchers considered two Harvard research, the first of thousands of women who followed the 62 are over 26 years old and the second which follows the 27,400 men aged more than 24 years. Overall, more than 2,500 people diagnosed with heart disease.
Relationship with blood type was made after researchers noticed another variable that could lead to heart disease like cholesterol levels, diabetes, and hypertension.
The result is surprising, said Dr. Richard Stein, kardiologis and spokesman for the American Heart Association. While other small studies have been mentions that there is a correlation, this study is the first large scale study that supports the correlation of it, he said.
Stein said during a follow-up research needed, blood type can be included in this list as a consideration when assessing a patient's doctor about the risk of heart disease, because the tests can express it is not expensive and without effect.
To reduce the risk of heart disease, a person should exercise, eat right and set weight loss as well as diligent controls cholesterol, Stein said.
Knowing that the type of blood can increase the risk of heart disease can also increase the motivation of people to "keep themselves and stop the bad habit," said Qi was quoted as saying in the webpage livescience.com. Researchers found a correlation between blood type with the risk of heart disease, not a causal relationship.

Other researchers cite the mechanism could explain these relationships, such relationships with blood type A certain type of cholesterol, and the relationship between the blood type AB with high inflammation.
This relationship is found in a very small research, Stein said, so more research is needed to be able to explain the korelasinya. In the United States, 45% of people have blood type O, so that it becomes the common blood type. Only 4% of the population in the United States who have blood type AB blood type, while there is A 40% and B blood type there is 11%.
