Non-O Blood Types Raise Risk

Your blood type impacts your health and longevity, and having a blood type other than O is associated with a higher chance of death, especially from heart disease. Large population studies have found that people with A, B, or AB blood have a slightly higher risk of coronary heart disease and blood clots compared with those who have type O. Researchers link part of this difference to clotting factors like von Willebrand factor and factor VIII, which tend to be higher in non-O blood types and can promote clot formation.
