Local sympathetic denervation improves cardiac function after myocardial infarction. (A) Ejection fraction, (B) fractional area change, and (C) stroke volume determined by echocardiography. Data are mean ± SEM of n = 9 (sham), n = 7 (SCGx), and n = 6 mice (MI, MI + SCGx). All four groups were compared by two-way analysis of variance with Bonferroni’s multiple comparison test. **P < 0.01, ***P < 0.001. (D–H) Analysis of myocardial strain by echocardiography-based speckle tracking. (D) Vector mapping of LV function. (E) Quantification of radial and (F) longitudinal strain by time-to-peak analysis. (G) 3D reconstruction of radial displacement in a single cardiac cycle. (H) Quantification of radial displacement in the time to peak analysis. Shown are mean ± SEM from n = 5 (sham, MI) and n = 4 (SCGx, MI + SCGx) mice. All four groups were compared by two-way analysis of variance with Bonferroni’s multiple comparison test. *P < 0.05, ***P < 0.001.
