Fig. 5. SrCO₃/HSA hydrogels improve the recovery of mice cardiac function after I/R.

(A) Schematic of I/R model establishment, hydrogel injection, and echocardiography (ECO) analysis. (B) Kaplan-Meier survival curves of mice during the 28 days after I/R. (C) Body weights of mice after I/R. (D) Representative echocardiograms obtained from the mid-papillary muscle region of the left ventricle of mice at day 28 (D28) after I/R. (E) Cardiac function measured by the percentage of LVEF and LVFS at days 1 and 28 after I/R. n = 10 each. All data are presented as means ± SEM. Comparisons between three groups were performed using two-way ANOVA. **P < 0.01.
