Scientification Explanations on Blood Type and Heart Health


A+, A-, B+, B+, O-, O+, AB+, and AB- blood types may be distinguished from one another based on the minute differences that circulate through our veins every second of every day. This is something that cannot be seen just by looking at a person.

When you are in the hospital and need a blood transfusion, or after you have given blood and determined the kind of blood you have, these little alterations often do not matter anymore. During delivery, when a specific therapy is required, many individuals learn for the first time that they have a negative blood type.


However, increased study into blood type suggests that it may imply more than we believed, at least when it comes to assessing risk for some health issues, including heart disease. This is one of the areas in which our understanding of blood type has expanded. These subtle changes in blood may give some individuals with an edge in avoiding cardiovascular illnesses, while rendering other people more sensitive to developing these conditions.

What does each of the many blood types mean, and how are they differentiated from one another?

The A, B, and O letters stand for distinct variations of the ABO gene that program human blood cells to create different blood types in a variety of different ways. These variants are denoted by the letters A, B, and O. If you have type AB blood, for example, your body is designed to produce A and B antigens on the red blood cells in your body. Antigens are not created by persons with type O blood because their immune systems are different.

Whether or not proteins are found on red blood cells is what determines whether or not blood is considered “positive” or “negative.” Rh-positive implies your blood includes proteins.


People who have blood type O- are considered to be “universal donors” since their blood does not contain any antigens or proteins, making it possible for it to be used by anybody in the event of an emergency.

But if this is the case, why do we have different blood types? The variation may have been caused by a number of factors, including where an individual’s ancestors originated, as well as earlier diseases that led to protective modifications in the blood, according to the opinions of many experts. Those with blood type O are more likely to get ill from cholera, while those with blood types A or B are more likely to have difficulties with the coagulation of their blood. Even while our blood can’t keep up with all of the many biological or viral threats that are circulating in real time, it may be able to reflect what has happened in the past.

The Implications of Your Blood Type on Your Heart’s Health


The blood types that are at the greatest risk for developing heart disease.

Persons who have blood types A, B, or AB have a higher risk of developing heart failure or having a heart attack compared to people who have blood type O, as stated by the American Heart Association.


The variation in blood clotting rates is significantly higher, according to the American Heart Association, even though the risk of heart attack and heart failure is relatively low (in one large study, types A and B had a combined 8% greater risk of heart attack and 10% higher risk of heart failure), the risk of heart attack and heart failure individually are relatively low. Deep vein thrombosis and pulmonary embolism are both significant blood clotting illnesses that may raise the risk of heart failure. People with blood types A and B were shown to be 51 percent and 47 percent more likely, respectively, to acquire these conditions.

Many researchers in the field of science think that inflammation in the bodies of people who have blood types A, B, or AB might be one of the factors that contribute to this increased risk. Blood proteins of type A and type B may contribute to an increased “blockage” or “thickening” in the veins and arteries, which in turn raises the risk of blood clots and cardiovascular disease.

Experts think that this might possibly explain the anecdotal decrease in risk of major COVID-19 illness in persons with type O blood, which has led to an inquiry into the matter. However, the reduction in risk has not been conclusively proven. In severe cases of COVID-19 illness, patients often have problems with their hearts, including blood clotting and other cardiovascular diseases.

Other repercussions stemming from one’s blood type

People who have type O blood have a decreased risk of heart disease and blood clots, but they have a higher chance of hemorrhaging and bleeding problems. This is because type O blood is less prone to clot. According to a research on postpartum blood loss, which suggested an enhanced risk among women with type O blood, this may be particularly true after delivery. The study looked at women who had given birth to babies with type O blood.


Those with type O blood may not fair as well after a catastrophic injury owing to the increased amount of blood loss, as stated in a research that was published in the journal Critical Care.


According to the findings of other research, those with blood type AB are at a greater risk of developing cognitive impairment than individuals with blood type O. Problems with one’s memory, ability to concentrate, and ability to make decisions are all instances of cognitive impairment.

Should I make adjustments to the way I live depending on my blood type?

Although a new research reveals that a person’s blood type might affect their probability of developing heart disease, other crucial variables such as diet, physical activity, and even the level of pollution in your area all play a part in determining how healthy your heart is.

The Implications of Your Blood Type on Your Heart’s Health

The majority of medical professionals believe that the only thing that should be recommended to patients who are seeking to keep their heart healthy is a diet that is excellent for the heart and reduces inflammation. This is the case regardless of the blood type of the individual.

However, scientists think that future research might give more specific methods for physicians to treat patients based on their blood type. If a patient has type O blood, then daily aspirin use is probably unnecessary; but, if the patient has type A blood and good cholesterol levels, then daily aspirin consumption may be beneficial.
