N = 4 or more. Abbreviations are: BW, body weight; HW, heart weight; TL, tibial length; HR, heart rate; IVSd, interventricular septal wall diameter; PWd, posterior wall diameter. Significance determined using GraphPad software. #P<0.05 compared with non-treated wildtype (+/+ NT) hearts by 1 way ANOVA, Newman-Keuls multiple comparisons test; δP<0.05 compared with pre-treatment values (not shown) by paired t-test, parametric, one-tailed.
