Type O Blood x CHD


Type O Blood Carries Lower CHD Risk

Patients with type A, B, or AB blood are at significantly greater risk for coronary heart disease (CHD) than those with type O blood, researchers found.
Two large, prospective cohort studies showed those with a non-O blood type had an age-adjusted hazard ratio of 1.09 (95% CI 1.03 to 1.17, P=0.005) for risk of developing CHD, according to Lu Qi, PhD, of the Harvard School of Public Health, and colleagues.
A meta analysis of an additional six past cohorts also showed a significant pooled relative risk for CHD in patients with non-O blood type of 1.11 (95% CI 1.05 to 1.18, P=0.001), Qi and co-authors wrote in the August 14 issue ofArteriosclerosis, Thrombosis, and Vascular Biology./.../
