Abstract:
OBJECTIVETo explore the association between the ABO blood group and the risk of myocardial infarction in Chinese people.
METHODSWe retrospectively recruited 1 988 consecutive patients with acute myocardial infarction (AMI) and 1 856 non-coronary artery disease (non-CAD) subjects who hospitalized in our hospital between January 2013 and December 2013. The clinical features and ABO blood group were analyzed.
RESULTSBlood group distribution was A (27.1%, 539/1 988), B (34.4%, 684/1 988), AB (10.8%, 215/1 988), O (27.7%, 551/1 988) in patients with AMI and A (26.7%, 496/1 856), B(32.2%, 598/1 856), AB(10.8%, 200/1 856), O (30.4%, 564/1 856) in non-CAD group. The single factor analysis showed that blood group O tended to be more common in the non-CAD group than in AMI group (P = 0.06). After adjustment for common cardiovascular risk factors such as age, gender, hypertension, diabetes, smoking and serum cholesterol level, the A, B, and AB blood groups were associated with increased risk of AMI compared with O blood group, and the difference was significant with A blood group (OR = 1.229, 95% CI 1.019-1.482, P = 0.031) and B blood groups (OR = 1.214, 95% CI 1.017-1.449, P = 0.032). In addition, non-O blood group remained significantly associated with the increased risk of AMI than O blood group after logistic regression analysis (OR = 1.223, 95% CI 1.048-1.426, P = 0.01).
CONCLUSIONOur results suggest that non-O blood group is associated with the increased risk of AMI.
