... failure patients. The sympathetic nervous system regulates involuntary movements such as heartbeat and blood pressure. Over-activation of sympathetic nerves is common in heart failure patients and associated with a poor prognosis because it forces the weakened heart to work harder and predisposes the heart ...Examining The Science Behind Nutraceuticals: Proceedings of the AAPS Dietary Supplements Forum
