Serial echocardiographic assessment of post-infarction remodeling. (A) Representative recordings of M-mode echocardiographic images at indicated time points. (B) Left ventricular end-systolic diameter (LVESd). (C) Left ventricular end-diastolic diameter (LVEDd). (D) Left ventricular systolic function presented by the left ventricular ejection fraction (LVEF). (E) Left ventricle fractional shortening (LVFS). *P < 0.05 vs the corresponding time point in the sham group. #P < 0.05 compared with the prior time point in the MI group. n = 8–10 at various time points.
