Exercise capacity. A–C: exercise duration, distance, and workload were lower in radiated rats than in control rats at 20 wk after radiation exposure. Data are presented as scatter dot plots, with lines showing mean and 95% confidence interval. *P < 0.05 vs. control. †Post hoc test for linear trend P < 0.003. D–F: severity of exercise intolerance (reduction in workload) was correlated with severity of increases in mean circulatory filling pressure (MCFP), reductions in microvascular density (MVD), and increases in LV fibrosis.
