Increased left ventricular mass (LVM), LVM index (LVMI) and left ventricular hypertrophy (LVH) are significantly associated with a higher incidence of clinical events including death. 1 Also, although increased LVMI and LVH may be associated with traditional cardiovascular risk factors, the presence of LVH predicts adverse cardiovascular events independent of underlying cardiovascular disease and risk factors. 1,2 However, the association of coronary anatomical parameters with LVM and LVMI remains unclear.Coronary artery dominance defines the anatomical variations in the coronary circulation. While right dominance (RD) is the most prevalent coronary circulation pattern in the general population and is seen in approximately 70%-80% of the population, co-dominance (CD) and left dominance (LD) patterns are seen in approximately 10%-20% and 10% of the population, respectively. 3 Although
