Figure 3. Nonlethal traumatic injury caused cardiac dysfunction, and quercetin alleviated trauma-induced cardiac dysfunction.

The cardiac haemodynamic parameters of the control, trauma, trauma + quercetin and trauma + vehicle group for 200 r were recorded 12 h after trauma. Mechanical trauma resulted in a significant decrease in LVDP (A), +dp/dtmax (B) and −dp/dtmax (C), which was effectively prevented by pre-treatment with quercetin. Statistical comparisons were performed using one-way analysis of variance. n = 5 rats/group, **P < 0.01 vs. sham; ^##P < 0.01 vs. trauma.
