High-fat-fed postpartum mice have increased cardiac output and stroke volume compared with high-fat-fed nulliparous mice. a Cardiac output. b Stroke volume. c Ejection fraction. d Fractional shortening after 20 weeks of low-fat (LF) or high-fat (HF) feeding in female nulliparous (NP) or postpartum (P) mice. Data are mean + SEM from n = 9–11 mice per group. *P < 0.05 compared with LF within group using 2-way ANOVA followed by Holm-Sidak pairwise analysis
