Abstract
Purpose
We examined the relationship between EFT measured by echocardiography and LV diastolic function parameters in a Beijing community population.
Methods
We included 1004 participants in this study. Echocardiographic parameters including E and A peak velocity, the early diastolic velocities (e’) of the septal and lateral of mitral annulus using tissue doppler imaging, E/e’, and EFT, were measured. EFT1 was measured perpendicularly on the right ventricular free wall at end-diastole in the extension line of the aortic root. EFT2 was the maximum thickness measured perpendicularly on the right ventricular free wall at end-diastole. Multivariate linear regression was used to analyze the relationship between EFT and the mean e’ and E/e’.
Results
The mean age of the participants was 63.91 ± 9.02 years old (51.4% men). EFT1 and EFT2 were negatively correlated with e’ lat, e’ sep, and e’ mean (p < 0.05), and positively correlated with E/e’ lat, E/e’ sep, and E/e’ mean. Multivariate regression analysis showed that EFT1 and EFT2 were independently and negatively correlated with e’ mean (EFT1: β = −0.089 [95% confidence interval = − 0.177, − 0.000, p = 0.050]; EFT2: β = −0.078 [95% confidence interval = − 0.143, − 0.012, p = 0.020]). There were no interactions between EFT and any covariates, including age or heart groups, sex, BMI, or presence of hypertension, diabetes, or coronary heart disease in relation to LV diastolic dysfunction.
Conclusions
EFT was negatively and independently correlated with e’ mean, suggesting that more attention to this type of adipose fat is required for cardiovascular disease therapy.
