People with blood type AB, one of the rarest, are most vulnerable to problems.
A survey conducted in the United States suggests that people with type O blood are less susceptible to heart problems compared to those with types A, B and AB.
The study, by scientists at the School of Public Health from Harvard University in Boston found that people with rarer blood type, AB, are more vulnerable to heart disease.
For these individuals, the probability of suffering from heart disease is 23% higher than for those with type O.
The research also found that for persons with type B blood, the risk of heart disease and increased 11% for persons with type A blood, the increase was 5%.
Researchers do not know the reason for this increase. Now, they will look like blood groups react to a healthier lifestyle.
"People can not change the blood type, but our findings may help doctors better understand who is at risk of developing heart disease. It's good to know your blood type, just as you should know your cholesterol or blood pressure blood, "said Professor Lu Qi, who led the study.
"If you know the risk is higher, you can reduce it by adopting a healthier lifestyle, by eating well, exercising and not smoking," he said.
The research was published in the journal "American Heart Association Journal."
The findings of American scientists are based on two large studies in the United States, one involving 62,073 women, and another 27,428 adults of both sexes. The volunteers were between 30 and 75 years and were followed for 20 years.
As the ethnicity of the people studied was predominantly Caucasian, the researchers say that is not yet clear whether the findings can be applied to other ethnic groups.
The blood type AB has been linked to inflammation, which play an important role in the damage to arteries. They also found evidence that the type A is associated with bad cholesterol, LDL, which can clog arteries.
Since individuals with type O blood can benefit from higher levels of a chemical element that helps in the flow and blood clotting.
However, the study did not analyze the reasons for the differing risks for blood types.
"Your blood type is very complicated, so there may be multiple mechanisms influencing (the differences)," said Lu Qi.
