People having a non- O blood group such as A,B or AB may be at an increased risk of suffering a heart attack, new research has found.

having a non-O blood group is associated with a 9%increased risk of coronary events and cardiovascular events especially myocardial infarction(heart attack)

The higher risk in non O blood group carriers maybe due to having greater concentration of von-Willebrand factor-a blood clotting protein,,researchers said.

Non-O blood group carriers, specifically those with an A blood group are known to have higher cholesterol and Galectin-3 protein ,linked to inflammation and worse outcome in heart failure patients.

Blood group should be considered in risk assessment for cardiovascular prevention
