Heart mass was measured at postnatal day 100, while echocardiogram was performed on postnatal day 90. Data are Means (SE). BPM, beats per min; BW, body weight; LV, left ventricular. ¥Systolic and diastolic diameters were divided by body weight to obtain a ratio for analysis, so that the unit is mm/kg of body weight. P-values ≤ 0.05 are bold. *p < 0.05 vs. Con-Con, #p < 0.07 vs. Con-Con, ‡p < 0.07 vs. HF-Con. p1 represents p-value of two-way ANOVA with factors including diet and treatment interaction.
