Abstract Purpose: To access the association between blood groups and coronary artery diseases, and to determine the causes that lead to this association. Methods: Ninety persons included in the study, 60 as patients group which are suffering from coronary artery diseases and 30 as controls group which are healthy and free from the diseases. The blood groups was analyzed and divided each group into four groups according to the blood groups, also the level of lipids in the blood measured by spectrophotometer. Results: The results of the study show that blood group O predominates in both studied group (patients and controls) in Al-Najaf Al-Ashraf city followed by A, B, and AB. The statistical analysis of the study shows the blood group AB of patients and blood group B of controls have a significant increment (P<0.05) in the serum level of total cholesterol. Also, the blood groups B and AB of patients have a significant increment in serum level of triglycerides. The blood group A of patients and blood group B of controls show a significant increment in the LDL cholesterol level, while blood groups A and B of patient have a significant reduction in HDL cholesterol serum level. Conclusions: The results of the study show that the blood group O is the most blood group in the Al-Najaf Al-Ashraf city, followed by blood group A, B, and AB. There is a high percentage of lipids level disturbance in the subjects of the blood groups (A, B, and AB). Also, there is a significant relation between blood groups (A, B, and AB) with the disturbance of the serum lipids levels which was associated with atherosclerosis disease, that was considered one of the most important risk factor that leading to the coronary artery diseases.
