Delivery of 2RJ hydrogel improves left ventricular morphology following MI. Pressure–volume hemodynamic measurements of (A) ESV, (B) EDV, (C) ESP, and (D) EDP. *p<0.05, **p<0.01, n≥5/group. One-way ANOVA followed by Tukey's post-test. ESV, end-systolic volume; EDV, end-diastolic volume; ESP, end-systolic pressure; EDP, end-diastolic pressure.
