This study evaluated left ventricular (LV) diastolic functional changes and left atrial (LA) functional indices using cardiac magnetic resonance (CMR) tissue tracking and volume-time curve in obese adults with no clinical signs or comorbidities. The association of LV diastolic function with fat distributions was also assessed. The results showed that CMR detected subclinical LV diastolic dysfunction, impaired LA reservoir and conduit function with preserved LV ejection fractions in adults with obesity. LV diastolic function was associated with LA reservoir and conduit function. Visceral fat was deleterious for LV diastolic function, while peripheral obesity might have had a protective effect.
