Résumé
Increased left ventricular mass index (LVMI) and left ventricular hypertrophy (LVH) are independent predictors of adverse cardiovascular events. However, little is known regarding the association between coronary circulation and LVMI. We aimed to investigate the association between coronary dominance and LVMI, and to demonstrate the impact of coronary dominance pattern on the emergence of LVH. In total, 367 consecutive patients without known cardiovascular disease and significant obstructive coronary artery disease who underwent diagnostic coronary angiography were prospectively included in the study. Patients were divided into three groups according to coronary dominance pattern. Patients with right dominance (RD), co-dominance (CD) and left dominance (LD) patterns were compared regarding echocardiographically detected LVMI. Additionally, the association between coronary dominance pattern and LVH was investigated. The frequency of RD, CD and LD patterns was 70.3%, 19.1% and 10.6%, respectively. LVMI was significantly higher in patients with CD pattern compared with those with RD and LD patterns (P < .001, for both comparisons). LVH was present in 71 (19.3%) patients. Importantly, the CD pattern was more frequent in patients with LVH compared with those without LVH (P < .001). No significant difference was found between women and men regarding the type of coronary dominance pattern. However, while the presence of CD pattern was found to be an independent predictor of LVH in women (OR:1.221, 95%CI:1.048-1.872, P < .001), no association was observed between coronary dominance pattern and LVH in men. Coronary dominance pattern may significantly affect the LVMI, and it may be useful in the further risk stratification of female patients.

BACKGROUND
BACKGROUND
Increased left ventricular mass index (LVMI) and left ventricular hypertrophy (LVH) are independent predictors of adverse cardiovascular events. However, little is known regarding the association between coronary circulation and LVMI. We aimed to investigate the association between coronary dominance and LVMI, and to demonstrate the impact of coronary dominance pattern on the emergence of LVH.
METHODS
METHODS
In total, 367 consecutive patients without known cardiovascular disease and significant obstructive coronary artery disease who underwent diagnostic coronary angiography were prospectively included in the study. Patients were divided into three groups according to coronary dominance pattern. Patients with right dominance (RD), co-dominance (CD) and left dominance (LD) patterns were compared regarding echocardiographically detected LVMI. Additionally, the association between coronary dominance pattern and LVH was investigated.
RESULTS
RESULTS
The frequency of RD, CD and LD patterns was 70.3%, 19.1% and 10.6%, respectively. LVMI was significantly higher in patients with CD pattern compared with those with RD and LD patterns (P < .001, for both comparisons). LVH was present in 71 (19.3%) patients. Importantly, the CD pattern was more frequent in patients with LVH compared with those without LVH (P < .001). No significant difference was found between women and men regarding the type of coronary dominance pattern. However, while the presence of CD pattern was found to be an independent predictor of LVH in women (OR:1.221, 95%CI:1.048-1.872, P < .001), no association was observed between coronary dominance pattern and LVH in men.
CONCLUSIONS
CONCLUSIONS
Coronary dominance pattern may significantly affect the LVMI, and it may be useful in the further risk stratification of female patients.
