  1. Data as mean ± standard deviation or median and 25th and 75th percentiles. AL: ad libitum fed; AL/IF: ad libitum before myocardial infarction (MI) and intermittently fasted after MI; IF: intermittently fasted before and after MI. Δ was calculated as [(final value minus initial value)/initial value] X 100. BW: body weight; HR: heart rate; LVDD and LVSD: left ventricular (LV) diastolic and systolic diameters, respectively; LA: left atrial diameter; E-wave and A-wave: early and late diastolic mitral inflow, respectively; IVRT: isovolumic relaxation time; IVRTn: IVRT normalized to heart rate; EDT: E-wave deceleration time; Δ Area: fractional area change. ANOVA and Tukey or Kruskal-Wallis and Dunn; * p < 0.05 vs AL; # p < 0.05 vs AL/IF
