EF: ejection fraction; ESV: end‐systolic volume; EDV: end‐diastolic volume; FS: fractional shortening; HR: heart rate; MI: myocardial infarction; NMI: non‐myocardial infarction; LV: left ventricular; LVEDD: LV end‐diastolic diameter; LVESD: LV end‐systolic diameter. Data are expressed as the mean standard error of the mean (n = 5).
# P < 0.05, versus NMI group. *P < 0.05, versus MI group.
