Body weight and echocardiography derived heart rate measured at the onset of treatment (day 7) and/or termination. Heart weight was measured after tissue clearing for light sheet imaging. End-diastolic LV chamber volume was estimated on parasternal long axis view at the time of termination. Data is mean ± s.e.m. One-way ANOVA with Tukey’s post hoc test. **p < 0.01 ***p < 0.001 vs sham—vehicle, #p < 0.05 vs LAD—vehicle.
