Comparison of the cardiac function of control and HFD rats.

Cardiac function	Control ()	HFD ()	value
Ejection fraction (%)	73.32 ± 0.8229	79.50 ± 1.799	0.0096
Stoke volume (μl)	322.2 ± 24.22	317.7 ± 23.52	0.8953
LV volume of ED (μl)	439.9 ± 32.71	399.0 ± 26.79	0.3415
LV volume of ES (μl)	117.7 ± 9.545	81.33 ± 7.833	0.0081
Cardiac output (μl/min)	133.7 ± 10.06	131.9 ± 9.765	0.8987
ED segmented wall thickness (mm)	3.061 ± 0.068	3.391 ± 0.098	0.0168

Values are expressed as mean ± SD. The cardiac function of the control and HFD rats was measured from CMR images and QMass Software; and versus control; LV = left ventricle; ED = end-diastolic volume; ES = end-systolic volume.
