Resistant Hypertension An Open, Complicated ("Cum Plicare") or Complex ("Cum Plexus") Syndrome?

Resistant arterial hypertension (RAH) is a complex and multifactorial syndrome, with hyperactivity of the sympathetic nervous system (SNS) and reduction of vagal activity being considered some of the main causes of refractoriness to treatment. Seen from the outside, it resembles a complicated (see lat. "Cum plicate") or complex disease (see lat. "Cum plexus"), Chaotic with the participation of several open systems. For example, in recent years some relationships have been demonstrated between the autonomic nervous systems, synaptic mediators, hormones, inflammatory and immune responses. However, these findings have not been investigated together and systematically. In the present project, we intend to establish and compare, in an integrated way, the clinical alterations present in RAH (resistant and refractory), hemodynamic variables, autonomous activity (sympathetic and baroreflex) and interactions with the neuroimmune-endocrine systems. To this end, we will test the hypothesis that resistant patients have greater damage to the autonomic nervous system (ANS) associated with exacerbated systemic and hormonal inflammatory profile, including SNA mediators (noradrenaline and acetylcholinesterase). This is also intended to determine the behavior (deterministic or chaotic) of the systems evaluated (mentioned above) in volunteers with RAH. Sample and methods: The sample space (calculated) will consist of 72 individuals, being: - 18 refractory hypertensive (HRT); II- 18 resistant hy…
