A+ and AB+ blood groups are risk factors for coronary artery disease in Iranian men and women respectively

The ABO blood group antigens, which represents genetic markers, are correlated with a number of diseases. However, the relationship between the ABO blood group system and coronary artery disease (CAD) is controversial. The aim of this study was to evaluate the association between ABO blood group system and CAD and its major risk factors. One thousand patients who underwent coronary angiography, were included. The study population comprised 590 males at a mean age of 56 ± 12 years and 410 females at a mean age of 59 ±13 years. There was no  difference in the  distribution of the ABO blood groups between the study  subjects  and the general population (healthy blood donors).Excluding gender,   there was no association between the  ABO blood groups and  CAD while, there was a  significant correlation between CAD and the   AB+  blood group in the  women (P=0.001) and the   A+   blood  group in the  men  (p=0.015).There was also  a  significant association between the absence of the  Rhesus antigen (Rh-) and normal coronary arteries (p=0.008) . Apropos the risk factors, the prevalence of the current risk factors of CAD was similar among the subjects with different ABO blood groups.
