Cardiac-specific overexpression of corin affects heart function in both early and late phase post-MI. (A) Dynamic changes in ejection fraction (EF%) (assessed by echocardiography), (B) lung weight to body weight ratio (LW/BW%), (C) systemic extracellular water (edema) assessed by quantitative magnetic resonance and (D) heart weight to body weight ratio (HW/BW%) in mouse groups of WT vs. corin-Tg post-MI. Portions of data from panels A, B, and D (WT group at non-MI, 3 h, 24 h, and 3 days) have been published previously [19] and are included here to reduce animal numbers. Differences between WT and corin-Tg at each study time point were analyzed by 2-way ANOVA with Sidak’s multiple comparisons. Data represent means ± SE of n = 3–34 mice per group at each time point. * p < 0.05, ** p < 0.01, **** p < 0.0001 and not significant.
