Aims Obesity carries significant risk for unfavorable ventricular remodeling and subsequent heart failure (HF) development, although the association between abdominal fat distribution and subclinical ventricular dysfunction is unclear. This study aimed to compare the subcutaneous and visceral abdominal adiposity with the risk of decreased ventricular strain. Methods We included 340 participants without overt cardiac disease who underwent laboratory testing, abdominal computed tomographic examination, and speckle-tracking echocardiography. Abdominal adiposity was quantitatively assessed as visceral fat area (VFA) and subcutaneous fat area (SFA) at the level of the umbilicus. Speckle-tracking echocardiography was performed to assess left ventricular global longitudinal strain (LVGLS) and right ventricular free-wall longitudinal strain (RVLS). Results Mean age was 56 ± 9 years, and 244 of the participants (72%) were male. The mean LVGLS and RVLS were −19.1 ± 3.0% and −25.0 ± 4.1%, respectively. Both VFA and SFA correlated with LVGLS (r = 0.46 and r = 0.15, both p &amp;lt; 0.01) and RVLS (r = 0.38 and r = 0.12, both p &amp;lt; 0.05), demonstrating a stronger correlation between VFA and ventricular strain. Multivariable analysis showed that VFA was significantly associated with LVGLS and RVLS, independent of traditional cardiovascular risk factors as well as pertinent laboratory and echocardiographic parameters (both p &amp;lt; 0.05), whereas SFA was not. Serum adiponectin level was correlated with LVGLS (r = –0.34, p &amp;lt; 0.001) and RVLS (r = –0.25, p &amp;lt; 0.001), although it lost statistical significance following multivariable adjustment. Conclusion In a sample of the general population, VFA, but not SFA, accumulation was significantly associated with decreased LV and RV strain, an association that may be involved in the increased risk of HF in obese individuals.
