Your blood type is important, especially when it comes to heart health

We all have one, and science suggests that our blood type may make a difference then how healthy our hearts are.

You may not know it by looking at the surface, but there are small variations in your veins every day that classify your blood in one of the following groups: A +, A-, B +, B-, O-, O +, AB +, and AB-. Unless you have a blood clot, a blood transfusion, or a pregnancy, you may never think twice about your blood type and what it means for your health.

Ongoing research on blood type suggests that credit may be more important than we give it, especially when assessing the risk of certain health conditions. heart disease. These invisible differences in the blood can give some people the advantage of preventing cardiovascular problems, and others can suffer.

What do blood types mean, and how are they different?

The letters A, B, and O represent different forms of the ABO gene that program our blood cells differently to form different blood groups. If you have type AB blood, for example, your body is programmed to produce A and B antigens in red blood cells. A person with type O blood does not produce antigens.

Blood is said to be “positive” or “negative” depending on whether there are proteins in the red blood cells. If your blood contains protein, you are Rhesus or Rh positive.

The ABO system is the most popular way to classify blood types.

People of the blood type are considered “universal donors” because the blood does not contain any antigen or protein, which means that anyone’s body can accept it in an emergency.

But why are there so many different types of blood? Researchers do not fully understand, but it is possible that past infections that caused protections in one’s blood and caused protective mutations in the blood may have contributed to diversity, according to Dr. Douglas Guggenheim, a hematologist at Penn Medicine. People with type O blood may become ill with cholera, for example, people with type A or B blood may be more likely to have blood clotting problems. Although our blood cannot keep up with the various biological or viral threats that are occurring in real time, it can reflect what has happened in the past.

“In short, it’s like the body has evolved around its environment to protect itself as best it can,” the Guggenheim said.

People with type A, type B, or type AB blood are more likely than people with type O blood to have a heart attack or heart failure, according to the American Heart Association.

Although the risk is small (type A or B had an 8% higher risk of heart attack and a 10% higher risk of heart failure, according to a large study) the difference in blood clotting rates is much higher, according to the AHA. People in the same study with type A and B blood were 51% more likely to develop deep vein thrombosis and 47% more likely to develop pulmonary embolism, which could increase the risk of severe blood clotting disorders and heart failure.

One of the reasons for this high risk, according to the Guggenheim, may be related to inflammation in the bodies of people with type A, type B, or type AB blood. Proteins in blood type A and B can cause more “blockage” or “thickening” of the veins and arteries, increasing the risk of clotting and heart disease.

The Guggenheim also believes that this could describe an anecdotal (but not currently crucial) reduction in the risk of serious COVID-19 disease in people with type O blood, which has prompted research. Severe COVID-19 diseases can cause heart problems, blood clotting, and other cardiovascular problems.

Other consequences of blood type

People with type O blood have a slightly lower risk of heart disease and blood clotting, but may have a higher risk of bleeding or bleeding. This may be especially true after postpartum, according to a study of postpartum blood loss, which has shown an increased risk in women with type O blood.

Blood type people may also be worse off after a traumatic injury as a result of increased blood loss, according to a study published in the journal Critical Care.

Other research has found that people with type AB blood may be at higher risk for cognitive impairment compared to type O people. It includes problems remembering, focusing, or making cognitive impairments.

Do I need to change my lifestyle according to my blood type?

Although research now shows that blood type can increase your risk of developing heart disease, there are major factors such as diet, exercise, or even the main factors that cause the level of contamination you suffer in your community. health.

The Guggenheim says that for patients who are trying to keep their heart healthy, there is no one who can make a special recommendation other than a good heart-healthy diet that reduces inflammation, regardless of someone’s blood type.

But he noted that future research may provide more definitive ways for doctors to treat patients according to their blood type. All things considered, taking a daily aspirin with cholesterol levels and healthy blood type A may be beneficial, but may not be necessary for a person on the same boat with type O blood.

“Following a balanced diet and a healthy heart will generally be what any doctor will recommend, and I would say that the ABO does not change that,” the Guggenheim said.

“I don’t think there is a protective benefit to having type O blood that helps to be scot-free,” he added.
