Key result
Right coronary dominance was associated with greater severity of coronary artery disease compared to left or codominance (adjusted β=6.699; 95% CI 1.193-12.205; p=0.017).
Why the study?
Is right coronary artery dominance associated with increased severity of coronary artery disease in patients undergoing coronary angiography?

Mean Difference: 6.699 (95% CI 1.193–12.205)
Absolute Event Rate: 42.3% vs 36.3%
p-value: p=0.017
Right coronary artery dominance is independently associated with greater angiographic severity of coronary artery disease compared to left or codominance.
Supports observed link to CAD severity on angiography; hypothesis-generating and requires prospective validation before clinical adoption.
Objective To investigate whether coronary artery dominance is associated with the severity of coronary artery disease (CAD). Design Cross-sectional study. Setting Single-centre. Participants Between July 2015 and February 2017, 1654 patients who underwent coronary angiography (CAG) were recruited into this cross-sectional study. Measurement and methods According to coronary dominance, patients were classified into left dominance (LD), right dominance (RD) and codominance (CD) based on the CAG results. Multiple linear regression analysis was performed to test the association between severity of CAD and coronary dominance. Results The total Gensini score was significantly higher in the RD group than in the left-CD group (42.3±33.6 vs 36.3±29.8; p=0.033). After adjusting for potential confounding factors, the results of multivariate linear regression showed that RD was associated with the severity of CAD (β=6.699, 95% CI 1.193 to 12.205, p=0.017). Conclusions The results suggest that right coronary dominance was associated with the severity of CAD.

John Hinton (1963) conducted a cross-sectional in Coronary artery disease (n=1,654). Right coronary dominance vs. Left dominance and codominance was evaluated on Severity of CAD (total Gensini score) (β=6.699, 95% CI 1.193 to 12.205, p=0.017). Right coronary dominance was associated with greater severity of coronary artery disease compared to left or codominance (adjusted β=6.699; 95% CI 1.193-12.205; p=0.017).
