Why the study?
It was unknown whether ABO blood groups are associated with the severity of coronary artery disease.
Is blood group A associated with increased severity of coronary artery disease in Chinese patients?
Is blood group A associated with increased severity of coronary artery disease in Chinese patients?
Blood group A is independently associated with increased angiographic severity of coronary artery disease in a Chinese population.
OBJECTIVE: To investigate whether ABO blood groups is associated with the severity of coronary artery disease (CAD). METHODS: Between January 2015 and December 2017, 1425 first diagnosed CAD patients confirmed by selective coronary angiography were recruited into this cross-sectional study, and their baseline characteristics, ABO blood groups, Gensini score were collected. Multiple linear regression analysis was performed to test the association between the severity of CAD and ABO blood groups. RESULTS: = 0.02) after adjusting for age, male, family history of CAD, hypercholesterolemia, smoking and hypertension. CONCLUSION: In this cross-sectional study, the data indicated that blood group A was an independent risk factor of severity of CAD in Chinese population and Chinese patients with type 2 diabetes.
