(A) Cardiac mechanical performance and (B) coronary vascular resistance of hearts with ischemia and reperfusion from the C (black circles), LPS (black squares), DG (white squares), and LPS + DG (white circles) groups. The hearts were isolated and dissected from rats with different treatments and perfused for 30 min. After that time, an ischemia-reperfusion period (I/R) was applied, I = 30 min and R = 60 min. Each heart was its own control to compare the pre-ischemic period vs. I/R, n = 6, p ≤ 0.05. CMP = Pre-ischemic period significance. * Control vs. LPS p = 0.001, β LPS vs. DG p = 0.001. Reperfusion significance: α DG vs. LPS + DG p = 0.02, ƛ LPS vs. LPS + DG p = 0.03. CVR = Pre-ischemic period: Ø LPS vs. DG p = 0.003. * LPS vs. LPS + DG p = 0.002. Reperfusion significance: ** DG vs. LPS + DG p ≤ 0.05.
