B-type natriuretic peptide in Parkinson's disease: a novel biomarker of dysautonomia

This study examines NT-proBNP levels as a potential biomarker for identifying cardiovascular autonomic dysfunction in Parkinson's disease patients. Elevated NT-proBNP was significantly associated with orthostatic hypotension and abnormal autonomic function tests, suggesting it may serve as an early indicator of cardiac autonomic denervation in PD.
