Proof of myocardial infarction (MI) by coronary artery ligation. Measurements were taken at day (D) 0, 1, 3, 5, and 7 after MI. a Infarct size (infarct weight as a percent of total LV weight). d Left ventricular infarct wall thickness (mm). c Fractional shortening (percent). d Ejection fraction (percent). e End systolic volume (µL). f End diastolic volume (µL). *p ≤ 0.05 vs. day 0, ^†p < 0.05 vs. day 1, and ^‡p < 0.05 vs. day 3 by one-way ANOVA followed by Newman–Keuls post hoc test, sample sizes are n = 10 day 0, n = 10 day 1, n = 11 day 3, n = 10 day 5, and n = 12 day 7
