ABSTRACT
Nonalcoholic fatty liver disease has been reported to be potentially linked to cardiovascular disease. Fatty liver index (FLI) is a noninvasive and simple predictor of nonalcoholic fatty liver disease. However, little is known about the relationship between FLI and cardiac function, especially in a general population. We investigated the relationships of FLI with echocardiographic parameters in 185 subjects (men/women 79/106) of the Tanno-Sobetsu Study, a population-based cohort, who were not being treated with any medication and who underwent echocardiography. FLI was negatively correlated with high-density lipoprotein cholesterol and peak myocardial velocity during early diastole (e'; r = -0.342, p <0.001), an index of left ventricular (LV) diastolic function, and ratio of peak mitral velocities during early and late diastole (E/A) and was positively correlated with age, systolic and diastolic blood pressures, creatinine, uric acid, homeostasis model assessment of insulin resistance, high-sensitivity C-reactive protein, ratio of mitral to myocardial early diastolic peak velocity (E/e'), left atrial volume index and LV mass index. No significant correlation was found between FLI and LV ejection fraction. Stepwise multivariable regression analysis showed that FLI was independently and negatively associated with e' after adjustment of age, gender, high-density lipoprotein cholesterol, homeostasis model assessment of insulin resistance, and high-sensitivity C-reactive protein. Conversely, e' was independently and negatively associated with FLI after adjustment of age, gender, systolic blood pressure, and LV ejection fraction. In conclusion, elevated FLI is independently associated with LV diastolic dysfunction in a general population without medication. FLI would be a novel marker of LV diastolic dysfunction as an early sign of myocardial injury.
