Blood group determines risk of thrombosis, study confirms
The risk of thrombosis is raised for non-O blood groups, with one in three thrombotic events attributable to these groups, according to a major Scandinavian study.
Those with non-O blood groups have a 92% higher risk of DVT, 80% higher risk of VTE and 75% higher risk of pulmonary embolism compared with group O individuals, the study of 1.1 million healthy blood donors from Sweden and Denmark shows.
The research also shows a modest increased risk of events such as MI among the non-O blood groups.
The overall population attributable risk of venous thrombosis risk for non-O blood groups was 36%
