Figure 1. Coronary flow reserve using Doppler echocardiography in rats. Stress test was performed on experimental groups using dobutamine (A) or adenosine (B) and CFR was calculated. O+SVF group exhibited increased CFR vs. OC in both adenosine and dobutamine conditions. P≤0.05 vs Young Control (*), vs Old Control (#), and vs Old+ SVF($); Data are presented as means±SD, analyzed with one-way ANOVA followed by post-hoc Dunn’s (A) or Holm-Sidak (B) test.
