According to a recent study, people who are having a non ‘O blood group’, A, B, AB, may be at 9% higher risk of suffering a heart attack and overall cardiovascular mortality compared to those people with ‘O blood group’
The research revealed that the higher risk could be because of having greater concentrations of ‘Von Willebrand factor’, which is a blood clotting protein associated with thrombotic events.
The study shows that people with ‘A blood group’ are known to contain higher cholesterol levels in their bloods, which is a leading risk factor a heart attack.
Those with a non ‘O blood group’ have higher galectin-3, which is a protein linked to inflammation and worse outcomes in heart failure patients.
The lead author of the study, Tessa Kole, who is a student at the University Medical Centre Groningen in the Netherla said: "The study demonstrates that having a non-O blood group is associated with a 9 per cent increased risk of coronary events and a 9 per cent increased risk of cardiovascular events, especially myocardial infarction."
Having A, B, AB blood groups is associated with a 9% increased risk of coronary events and a 9% increased of cardiovascular events.
The study was presented at the fourth World Congress on Acute Heart Failure and at the Heart Failure 2017.
The team conducted a meta-analysis on O and A, B, AB blood groups and incident cardiovascular events including myocardial infarction, coronary artery disease, ischemic heart disease, heart failure, cardiovascular events and cardiovascular mortality.
Kole suggested that “Blood group should be considered in risk assessment for cardiovascular prevention, together with cholesterol, age, sex and systolic blood pressure."
