A blood type other than group O has a higher risk of heart disease. This was indicated by a study by the United States National Institute of Healthwhich analyzed more than 50,000 samples of people over a period of seven years.
The investigation was carried out by the specialist doctor Arash Etemadi. The analysis included participants from Iranwho were given continuous clinical follow-up. The results indicated that people with blood type A, B and AB showed a greater predisposition to heart disease.
The report detailed that those who belong to these blood groups face a 9% increased risk of death from any cause and a 15% more likely to die from heart disease. Furthermore, that same group presented a 55% increased risk of developing gastric cancer.
Dr. Etemadi explained that this vulnerability could be related to own biological characteristics of groups A, B and AB. In the case of type Athe researchers detected higher LDL cholesterol levelsknown as bad cholesterol. This condition increases cardiovascular risk.
The study also noted that people with a blood group other than O tend to clot more easily in the veins. This phenomenon increases the risk of suffering a heart attack or other serious complications of the circulatory system.
The researchers clarified that cardiac risk does not depend only on blood type. The World Health Organization (WHO) indicated that maintaining a healthy diet and perform regular physical activity reduces the risk of heart disease by 30% on average.
How are blood groups classified?
The blood groups are defined according to the presence or absence of antigens on the surface of red blood cells. That combination determines each person’s blood type.
- Group A: red blood cells present antigen A. Plasma contains anti-B antibodies.
- Group B: red blood cells present B antigen. Plasma contains anti-A antibodies.
- Group AB: red blood cells present antigens A and B. Plasma does not have anti-A or anti-B antibodies. This group can receive any blood from the ABO system.
- Group O: red blood cells do not present A or B antigens. Plasma contains anti-A and anti-B antibodies. This group is considered universal giver.
Each group is also classified as Rh positive or negativedepending on the presence of a specific protein in red blood cells.
Other investigations indicated that the relationship between blood groups and heart diseases could be influenced by genetic and environmental factors. It was also identified that the chronic inflammationmore common in some groups, plays a relevant role in the development of these conditions.
