Abstract :

There are solid grounds for recognition of importance of multiple neuronal/neurotransmitter networks in the regulation of the cardiovascular system. Clinical and preclinical studies provide evidence that heart failure is associated with significant changes in central control of some of these systems. In addition, it has been shown that some of the brain?s neurochemical pathways, which are involved in central control of blood pressure, play a role in the regulation of emotions and cognitive functions. Stress and depression are regarded as potential challenges for the cardiovascular system, causing inappropriate regulation of cardiovascular parameters and worsening prognosis of heart failure. There is also evidence that heart failure increases sensitivity to stress and depression. Recently, the knowledge of neurochemical background of comorbidity of stress, depression and heart failure increased markedly. Our studies and those of other authors provided evidence for significant role of improper function of neuropeptides, and in particular of angiotensinergic, vasopressinergic and oxytocinergic systems in exaggerated responsiveness of the cardiovascular system to stress in heart failure and depression. Current evidence indicates that inappropriate regulation of release of these neuropeptides and/or expression of their receptors play particularly important role in long-term changes of central cardiovascular control during post-infarct heart failure
