Vasoactive hormones in uraemic patients with chronic hypotension.
The results indicate that in HD patients with chronic hypotension there is an activation of the sympathetic and the renin-angiotensin systems, probably secondary in an attempt to compensate the vascular resistance to pressor stimuli reported in these patients.
Autonomic nervous system and adrenergic receptors in chronic hypotensive haemodialysis patients.
Increased plasma catecholamine levels induced an a 2 and b 2 -adrenoceptor downregulation and autonomic nervous system dysfunction and adrenoceptor alterations in the pathophysiology of CH HD patients.
