People with these blood groups are more prone to heart attack! Click here to know


According to new research from the Harvard School of Public Health (HSPH), heart attack may be linked to blood type. According to the American Heart Association, people with type A, type B or type AB blood are more likely to have a heart attack than people with type O.

According to one large study, types A or B have a combined 8% higher risk of heart attack and 10% increased risk of heart failure. Researchers also found that people with the AB blood group were 23% more likely than others to develop heart disease. People with type B had an 11% increased risk, and people with type A had a 5% increased risk.

Proteins in type A and type B blood can lead to more blockage or thickening of veins and arteries, which increases the risk of clots and heart disease.


According to the European Society of Cardiology, the risk of heart attack or heart failure among non-O blood types may be due to the fact that they are more likely to form blood clots. Researchers from a 2017 study reported that those with the non-O blood group had a higher concentration of von Willebrand factor. von Willebrand is a blood clotting protein that has been associated with thrombotic events.
