Higher risk of heart attack if non-O blood group? PDF Print Email

Latest research suggests people with a non-O blood type have a slightly increased risk of heart attack or stroke.

 

The researchers think it may be because people with A, B and AB blood groups have a higher level of a blood-clotting protein.

 

This research should not cause alarm as it is a slightly increased risk and it does not allow for the fact that everyone should focus on giving up smoking, eating a healthy, balanced diet and taking exercise as far more important factors in preventing heart attacks or stroke.

 

Having said that the research did involve a study of 1.3 million people so has a proper study size and looked at coronary events in more than 770,000 people with  non-O blood group and more than 510,000 people with O blood group.

 

About 1.5% of non-O blood group and 1.4% in O blood group experienced a heart attack or angina.

They also studied cardiovascular events in 708,000 people with non-O blood and 476,000 with O blood, which affected 2.5% and 2.3% of each group respectively.

Significantly, as opposed to the headlines when the researchers looked at fatal heart events, they found no major difference in risk between the O and non-O blood groups.

 

It was presented at the European Society of Cardiology congress.

 

It revealed that 15 in 1,000 people with a non-O blood group suffered a heart attack compared to 14 in 1,000 people with blood group O which although is a small increase in risk becomes more significant when looked at in terms of the whole population as previous research has found that people with the rarest blood group - AB - were the most vulnerable to suffer heart disease, a 23% risk increase.

 

48% of the population in the UK have blood group O which makes it the most common blood group.

 

There are a number of factors which can increase the risk of heart disease, such as smoking, being overweight and an unhealthy lifestyle and these can have a far more profound effect on our risk of heart disease.  However, they are all things that we can do something about – we cannot alter our blood group.

Your parents genes determine which blood group you are.

 

The research was from the University Medical Centre Groningen in the Netherlands and study author, Tessa Kole, said more research was needed to establish the reason cardiovascular risk increased in non-O blood group people.

She said: "In future, blood group should be considered in risk assessment for cardiovascular prevention, together with cholesterol, age, sex and systolic blood pressure."

For example, people with blood group A, who are known to have higher cholesterol in their blood may need a reduced treatment level for high blood pressure.

The associate medical director at The British Heart Foundation, Dr Mike Knapton, said the findings would not have a large impact on the current guidelines used to assess someone's risk of a heart attack.

"Most of a person's risk estimation is determined by age, genetics (family history and ethnicity) and other modifiable risk factors including diet, weight, level of physical activity, smoking, blood pressure, cholesterol and diabetes.

"People with a non-O blood group type - AO, BO and AB - need to take the same steps as anyone wanting to reduce their CVD risk.

"That includes taking sensible steps to improve their diet, weight, level of physical activity and not smoking, and where needed, manage blood pressure, cholesterol and diabetes."
