Non-O blood group ’linked to higher heart attack risk’
It found 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.
The analysis looked at coronary events in more than 770,000 people with a non-O blood group and more than 510,000 people with an O blood group.

People with a non-O blood group have a slightly increased risk of heart attack and stroke, research suggests.
Study author Tessa Kole, from the University Medical Center Groningen in the Netherlands, said more research
was needed to work out the cause of the increased cardiovascular risk in people with a non-O blood group.
Previous research found that people with the rarest blood group - AB - were the most vulnerable, being 23% more likely to suffer heart disease.
Dr Mike Knapton, associate medical director at the British Heart Foundation, said the findings would
not have a large impact on the current guidelines used to assess someone’s risk of a heart attack.
She said: "In future, blood group should be considered in risk assessment for cardiovascular
prevention, together with cholesterol, age, sex and systolic blood pressure."
But a heart charity said people should focus on giving up smoking and eating healthily to reduce their risk.
They also looked at 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.
