Comparison of the cardiac function of control and HFD rats.
| Cardiac function | Control (n=9) | HFD (n=9) | P 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; ∗ P < 0.05 and ∗∗ P < 0.01 versus control; LV = left ventricle; ED = end-diastolic volume; ES = end-systolic volume.
