Abstract
NUNEZ MARTINEZ, Agustina Beatriz and MATOS FRONTADO, Yimber Manuel. Motor phenotype and cardiovascular dysautonomia in patients with Parkinson's disease from a neurology outpatient clinic in Táchira (Venezuela). Acta Neurol Colomb. [online]. 2022, vol.38, n.4, pp.201-210. Epub Feb 01, 2023. ISSN 0120-8748. https://doi.org/10.22379/24224022428.
INTRODUCTION:
Parkinson's disease is a frequent neurodegenerative disorder characterized by motor and non-motor manifestations, such as dysautonomia, sleep disorders, sexual dysfunction, and psychiatric and cognitive disorders. It can be classified according to their motor phenotype in tremor-dominant (TD), postural instability/gait difficulty (DMI), and indeterminate subtypes. This study established the influence of motor phenotype on the cardiovascular dysautonomia of patients with Parkinson's disease from the neurology outpatient clinic at the IVSS hospital "Dr. Patrocinio Peñuela Ruiz," from May 2015 to April 2016.
METHODS:
Observational, descriptive, cross-sectional study in patients older than 40 years with idiopathic PD. The MDS-UPDRS scale, Hoehn and Yahr scale, Scopa-AUT scale, Orthostatic Hypotension, and RINES-VALCARDI were evaluated.
RESULTS:
A sample of 57 was obtained, and after applying inclusion and exclusion criteria, 37 subjects were studied. All the patients had some degree of dysautonomia (measured with SCOPA- AUT scale). The SCOPA-AUT was higher in patients with orthostatic hypotension (p= .003), finding this same difference for the cardiovascular subscale (p = .026). Both autonomic neuropathy (measured with RINES-VALCARDI) and orthostatic hypotension were found more frequently on the DMI phenotype (p= <.001 and p=.016).
CONCLUSION:
Dysautonomia is frequent in PD patients; there was a difference between SCOPA-AUT total score and cardiovascular subscale according to orthostatic hypotension; those with DMI phenotype have a greater risk of orthostatic hypotension and cardiac autonomic neuropathy.
