M-mode echocardiographic analysis in experiment rats. a Representative echocardiographic images (n = 8, each group). b, c The ratio of heart weight (HW) and left ventricle weight (LVW) to tibia length (TL). d–g The changes in LV diastolic internal dimension (LVDD), interventricular septum end diastolic thickness (IVSd), posterior wall thickness at the end-diastole (LVPWd), and LV ejection fraction (EF), determined by echocardiography. *p < 0.05 vs sham group; #p < 0.05 vs TAC group; +p < 0.05 vs PCM-E2/PFPs + LIFU group
