Lifestyle Why you should be worried if you have blood groups A, B & AB

Your blood group could pose danger on you

A study has indicated that people with blood groups A, B and AB are more susceptible to heart attacks.

The report made during the 2017 European Society of Cardiology meeting showed that people with blood type O were unlikely to get cardiovascular diseases.


Tessa Kole, a Master's degree student at the University Medical Centre Groningen, was part of the research highlighted that: “We demonstrate that having a non-O blood group is associated with a 9% increased risk of coronary events and a 9% increased risk of cardiovascular events, especially myocardial infarction”. 

The study involved over 700,000 individuals with a non-O blood group and over 500,000 with blood group O.


Out of this 11,437 persons with non-O blood group suffered a heart attack while only 7,220 with blood group O experienced the coronary attack.

However, Ms. Kole noted that more studies needed to be done to confirm the findings.

“It has been suggested that people with non-O blood groups (A, B, AB) are at higher risk for heart attacks and overall cardiovascular mortality, but this suggestion comes from case-control studies which have a low level of evidence. If this was confirmed it could have important implications for personalised medicine." Kole said.

It is important to contact your doctor in order to know your blood group.
