Blood Type

Most people focus on their heart health via diet modification and exercise in an effort to prevent cardiovascular disease. The risk of death by heart disease is very real; it remains one of the leading causes of fatalities, according to the World Health Organization.

Even with the best physical care, there are other things that are out of your control which can put you at extreme risk of a cardiovascular event. In fact, research has shown that your blood type can actually put you at extreme risk of a heart attack.

4. Blood Type and Heart Attack

Heart Attack

In a recent study of 400,000 people published in Arteriosclerosis, Thrombosis and Vascular Biology, it was found that people with blood types A or B had only a combined 8 percent increased risk of a heart attack.

In an earlier study from 2017, research was carried out by the European Society of Cardiology. The total number of people who participated in the study was 1.36 million. Their results showed that individuals with non-O negative blood types had a 9 percent increase in suffering a serious cardiovascular event.

Out of all of the blood types, those with blood type B might be at the highest risk of a heart attack. Individuals with type B seemed to have a 15 percent increased risk of myocardial infarction compared to those with type O.

3. Blood Type A and Heart Failure

Heart Failure

Individuals with blood type A were shown to have a 11 percent higher risk of developing heart failure. Heart failure develops slowly compared to a heart attack, which can strike suddenly and with little warning. Although, after sustaining a heart attack, an individual might go on to develop heart failure.

At this point, researchers have several theories about why blood type matters when it comes to a heightened risk of heart attack or heart failure. They theorize that non-O blood types might be at increased risk of developing dangerous blood clots. Without a doubt, blood clots contribute to heart attack and are usually the leading cause of the cardiac event. The blood clot blocks the coronary artery, leaving the heart muscle starved for life-sustaining oxygen and nutrients. When this happens, a heart attack occurs.
