    Study Notes

    Diagnosis and Management of Nocturnal Supine Hypertension in Cardiovascular Autonomic Failure

    • Nocturnal supine hypertension (nSH) is present in 34-46% of patients with Parkinson's disease (PD) and 37% of patients with multiple system atrophy (MSA).
    • Loss of nocturnal blood pressure (BP) dipping is common in PD and MSA patients.
    • The prevalence of nSH in pure autonomic failure (PAF) ranges from 48-70%.
    • There is a significant association between the presence of nOH and rising nocturnal BP profiles in patients with type 1 and type 2 diabetes mellitus.
    • Anti-hypotensive drugs used for the treatment of nOH may unmask or exacerbate nSH.
    • Multiple factors contribute to nSH, including impairment of the afferent, central, and efferent pathways of the arterial baroreflex arch, disruption of the renin-angiotensin-aldosterone axis, and denervation supersensitivity at the level of the vascular adrenoceptors.
    • Noradrenaline release from intact post-ganglionic sympathetic fibers drives nSH in MSA, while mechanisms independent of the sympathetic autonomic nervous system contribute to nSH in PAF.
    • Patients with nOH should be screened for nSH at diagnosis and at regular intervals afterward.
    • Office screening for nSH should be performed by measuring supine BP as soon as the patient assumes the supine position and then again after the patient has been resting supine for at least 5 minutes.
    • Home BP recordings performed by patients themselves are recommended to gather further insights into circadian BP control.
    • A diagnosis of nSH should be made independently from seated BP values, which may vary in patients with cardiovascular autonomic failure.
    • Cut-offs for nSH diagnosis in the context of cardiovascular autonomic failure are based on the criteria for the diagnosis of essential hypertension and interpretation of 24-hour ambulatory BP monitoring recordings in the general population.
