Abstract

Abstract: Aim: Previous studies showed that non‐alcoholic fatty liver disease (NALFD) could be related to subclinical left ventricular (LV) diastolic dysfunction and remodeling. However, this association is still equivocal in the general population. Thus, this study was carried out to examine whether NAFLD is associated with the risk for LV diastolic dysfunction and remodeling. Methods: A cross‐sectional study was carried out for 20 821 Korean men and women who received a health checkup including echocardiography from 2011 to 2012. The study population was divided into three groups of normal, mild and moderate‐to‐severe NAFLD detected by ultrasonography. Using multivariable logistic regression analysis, the odd ratios of abnormal LV relaxation and remodeling were analyzed according to the degree of NAFLD. Additionally, adjusted mean values of LV diastolic functional and structural parameters were evaluated in the three groups. Results: Compared with the normal group, the mild and moderate‐to‐severe NAFLD groups had higher odd ratios for abnormal LV relaxation (mild group 1.29, 95% confidence interval 1.15–1.46; moderate‐to‐severe group 1.95, 95% confidence interval 1.61–2.35) and increased relative wall thickness (>0.42; mild group 1.26, 95% confidence interval 1.05–1.52; moderate‐to‐severe group 1.46, 95% confidence interval 1.08–1.95). Analyzing adjusted mean values of LV parameters also showed the significant association between the degree of NAFLD and impaired LV diastolic function and concentric LV remodeling. Conclusions: The risk for LV diastolic dysfunction and remodeling proportionally increased according to the degree of NAFLD. NAFLD is significantly associated with LV functional and structural alteration.
