Is There Any Relationship between ABO Blood Groups and Coronary Ectasia?

Coronary artery ectasia (CAE) is known as dilatations of coronary vessels which are 1.5 times greater than the adjacent healty segment and it is known to variant of atherosclerosis. Previous reports have shown that the ABO blood groups are associated with atherosclerosis. In this study, it was investigated whether coronary artery ectasia is related to genetically transmitted ABO blood groups.


This retrospective study involved 620 subjects who underwent coronary angiography in our center from 2015 to 2018. The control group of the study consisted of 310 patients whose coronary arteries were angiographically normal. Three hundred and ten patients who had ectasia in at least one of the coronary arteries were selected as the patient group. ABO blood groups were determined in two groups using standard agglutination techniques. Blood groups were compared between the patients and the control group.


There were no significant differences between the two groups in terms of blood groups frequency (P > 0.05, for all).


Even though multiple studies showed an association of cardiovascular diseases and ABO blood groups, no association was determined between CAE and any blood groups in this study.
