Left ventricular (LV) dilatation and contractile dysfunction. A‐C, Echocardiographic measurement of A, LVDs—LV systolic diameter; B, LVDd—LV diastolic diameter; and C, FS—fractional shortening of sham‐operated (Sham) and failing (HF) hearts before (Day 0) and 42 d after (Day 42) myocardial infarction; D, E, Analysis of collagen content by means of hydroxyproline assay. Sham—sham‐operated group; HFni—non‐infarcted tissue; HFi—infarcted tissue. Data are presented as mean ± SEM, n = 7‐9 per group. *P < 0.05 vs Sham, ^# P < 0.05 vs HFni
