Line graph depicting a percentage change of stroke volume (SV) from the basal level before exposure (pre-exposure control vs MWCNTs at 1 day post: 109.3 ± 7.0 vs 106.7 ± 10.4 μl, control vs MWCNTs at 7 days post: 118.8 ± 5.7 vs 127.5 ± 3.7 μl). Each value represents the mean ± SE of eight rats. P < 0.01 exposed compared with control group at 1 day post-exposure (*)
