The pathophysiology of heart failure (HF) is characterized by an abnormal activation of neurohumoral systems, including the sympathetic nervous and the renin-angiotensin-aldosterone systems, which have long-term deleterious effects on the disease progression. Perpetuation of this neurohumoral activation is partially dependent of central nervous system (CNS) pathways, mainly involving the paraventricular nucleus of the hypothalamus and some regions of the brainstem. Modifications in these integrative CNS circuits result in the attenuation of sympathoinhibitory and exacerbation of sympathoexcitatory pathways. In addition to the regulation of sympathetic outflow, these central pathways coordinate a complex network of agents with an established pathophysiological relevance in HF such as angiotensin, aldosterone, and proinflammatory cytokines. Central pathways could be potential targets in HF therapy since the current mainstay of HF pharmacotherapy aims primarily at antagonizing the peripheral mechanisms. Thus, in the present review, we describe the role of CNS pathways in HF pathophysiology and as potential novel therapeutic targets.
心力衰竭(HF)的病理生理学特征是神经体液系统异常激活,包括交感神经系统和肾素-血管紧张素-醛固酮系统,这些系统对疾病进展具有长期有害影响。这种神经体液激活的持续存在部分依赖于中枢神经系统(CNS)通路,主要涉及下丘脑室旁核和脑干的一些区域。这些中枢神经系统整合回路的改变导致交感神经抑制减弱和交感神经兴奋通路加剧。除了调节交感神经输出外,这些中枢通路还协调了一个复杂的因子网络,这些因子在HF中具有既定的病理生理学相关性,如血管紧张素、醛固酮和促炎细胞因子。由于目前HF药物治疗的主要手段主要针对外周机制,中枢通路可能是HF治疗的潜在靶点。因此,在本综述中,我们描述了中枢神经系统通路在HF病理生理学中的作用以及作为潜在的新型治疗靶点。
