Key result
Visceral obesity was associated with a smaller left ventricular end-diastolic volume and lower ejection fraction (VAT: β -0.24; 95% CI -0.35 to -0.12), particularly in men.
Why the study?
The associations of body fat distribution with cardiovascular function and geometry in the middle-aged general population remained to be evaluated.
How do visceral and general obesity impact left ventricular function and geometry in a middle-aged general population?

Findings on fat distribution and LV parameters should not change practice; leaves open causal effects for longitudinal studies.

How do visceral and general obesity impact left ventricular function and geometry in a middle-aged general population?
Effect estimate: β -0.24 (95% CI -0.35 to -0.12)
Visceral obesity is associated with smaller LV end-diastolic volume and subclinical lower LV systolic function in men, suggesting it plays a more important role in LV remodeling compared to general obesity.
Hout et al. (2019) conducted a cross-sectional in General population (n=4,590). Visceral and general obesity was evaluated on Left ventricular parameters including end-diastolic volume, ejection fraction, cardiac output, and cardiac index (β -0.24, 95% CI -0.35 to -0.12). Visceral obesity was associated with a smaller left ventricular end-diastolic volume and lower ejection fraction (VAT: β -0.24; 95% CI -0.35 to -0.12), particularly in men.
