Longitudinal assessment of RV and LV in male rats. (a) Experimental design and representative cardiac MRI images acquired at 0, 2-, and 4-weeks MCT (a) and 4-, 6-, 8-, 10-week SuHx (c). Cardiac MRI derived metrics to assess hypertrophy, dilatation, and systolic function of RV and LV in MCT (b) and SuHx rats (d). Results are presented as fold change from baseline values (mean ± SD, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, one-way ANOVA, comparison to healthy controls, Dunnett correction for multiple comparisons): 0-weeks (n = 12), 2-weeks MCT (n = 12), 4-weeks MCT (n = 9), 4-weeks SuHx (n = 7), 6-weeks SuHx (n = 15), 8-weeks SuHx (n = 10), 10-weeks SuHx (n = 10).
