| RV ED volume, μL | 234 ± 32 | 180 | 263 ± 27 | 236 | 266 |
| RV ES volume, μL | 80 ± 26 | 51 | 135 ± 41 | 109 | 148 |
| RV stroke volume, μL | 155 ± 28 | 129 | 128 ± 48 | 127 | 118 |
| RV ejection fraction, % | 66 ± 10 | 72 | 48 ± 16 | 54 | 44 |
Values are means ± SD and measured by invasive catheterization for control and sugen-hypoxia (SuHx) week 4 groups compared with those in individual animals measured using cardiac magnetic resonance imaging (cMRI). ED, end-diastolic; ES, end-systolic; RV, right ventricular.
