Figure 4: Heart function recovery after ischemia/reperfusion with and without hyperosmotic perfusion. The post-ischemia/reperfusion recovery of heart function and work product were better in hyperosmotic perfused Wistar- Kyoto rats (WKY) and stroke-prone spontaneously hypertensive rats (SHRSP). LVDP, left ventricular developed pressure; RPP, rate-pressure product. n=7-10. *P<0.05, **P<0.01 versus respective controls.
