Nocturnal hypertension and dysautonomia in patients with Parkinson's disease: are they related?
Orthostatic hypotension and supine hypertension frequently coexist in Parkinson's disease (PD) patients, leading to visceral damage and increased mortality rates. The aim of this paper is to analyze the frequency and association of both conditions in a sample of outpatients with PD. A total of 111 patients, diagnosed with PD, were studied. ⋯ The majority of patients with Parkinson's disease show an altered circadian rhythm of blood pressure. Patients with a non-dipper or riser pattern on 24 h ABPM exhibited a higher prevalence of autonomic disorders (orthostatic hypotension) and received higher doses of dopaminergic treatment. A day-night variation in diastolic blood pressure was the most important marker of these findings.
