Figure 5. Effect of different durations of ischemia on heart failure after reperfusion. (A) Flow chart of the experimental protocols. (B) Representative echocardiographic images and statistical data of left ventricular internal dimension in systole (C, LVIDs), end-systolic volume (D, ESV), left ventricular ejection fraction (E, EF%), fractional shortening (F, FS%) of mice (n = 5 : 5 : 5 : 5). MI=Myocardial infarction, Rep=reperfusion. Data are shown as mean ± SD. One-way ANOVA followed by Tukey post hoc test was used for statistical comparisons between multiple groups. *P < 0.05; ***P < 0.001.
