Is it true that ABO blood type is associated with the risk of cardiovascular disease and venous thrombosis?

Unclear. Several peer-reviewed sources report that non-O ABO blood groups are associated with elevated risk of venous thromboembolism, and one systematic review and one narrative review also describe associations with cardiovascular disease, though the evidence is largely limited to specific populations or subtypes. No retrieved item settles the full general claim across both outcomes.
