Abstract
Background: Left ventricular hypertrophy (LVH) is a key predictor of cardiovascular disease. This study aimed to investigate the correlation between LVH and regional adipose tissue deposits, including visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and epicardial adipose tissue (EAT), and sex-related differences in these correlations. Methods: A total of 416 individuals (median age 66 years, range 20-95), without structural heart disease or a history of hypertension and coronary artery disease, underwent echocardiography and abdominal computed tomography. Statistical analyses included logistic and linear regression to assess the associations between adipose tissue measures and LVH. Results: LVH was associated with older age, higher systolic blood pressure, and increased EAT thickness. EAT thickness was independently associated with LVH in women (OR 1.21, 95% CI 1.03-1.44, p = 0.024) but not in men. Scatter plot analysis revealed a positive correlation between EAT and left ventricular mass index (LVMI) in women (r = 0.366, p < 0.001) and a negative correlation in men (r = -0.153, p = 0.038). Conclusions: VAT and SAT showed no significant associations with LVMI or LVH in either sex. These findings suggest that EAT, but not VAT or SAT, is linked to cardiac remodeling in a sex-specific manner.
