Does fibroblast growth factor-1 prevent myocardial apoptosis triggered by ischemia reperfusion injury?
The programed myocyte cell death triggered by ischemia-reperfusion injury is attenuated by FGF-1 in its native or non mitogenic isoforms, suggesting that this effect does not depend on the mitogenic properties of this protein. FGF-1 would contribute to the functional preservation of the myocardium after acute myocardial infarction.
Ingestion of 10% glucose water impairs head-up tilt tolerance relative to water ingestion. The contrasting effect of 10% glucose water vs. pure water on orthostatic tolerance is associated with increased heart rate and attenuation of the increase in peripheral vascular resistance in head-up tilt testing.
