Key result
Parkinson's disease linked to ~5% higher odds of orthostatic systolic BP drop in elderly patients.
Why the study?
Parkinson's disease is frequently associated with cardiovascular autonomic failure and blood pressure dysregulation, such as orthostatic hypotension and impaired nocturnal dipping, which increase fall and cardiovascular risk in elderly patients. This study evaluated 24-hour blood pressure profiles and orthostatic responses in Parkinson's disease patients versus non-Parkinson's disease controls in a cardio-geriatric setting.

Elderly patients with Parkinson's disease exhibit a distinct dysautonomic blood pressure phenotype characterized by severe 1-minute orthostatic systolic blood pressure drops, post-prandial hypotension, and nocturnal hypertension driven by an inverted dipping profile.
24-hour BP monitoring may aid autonomic assessment in elderly PD patients; leaves open whether it reduces falls or events.
Introduction. Parkinson’s disease (PD) is frequently associated with cardiovascular autonomic failure, leading to significant blood pressure (BP) dysregulation. Patterns such as orthostatic hypotension (OH) and impaired nocturnal dipping increase the risk of falls and cardiovascular events in elderly patients. Objectives. To evaluate the 24-hour BP profile and orthostatic responses in PD patients compared to non-PD controls in a cardio-geriatric setting. Materials and Methods. This retrospective study analyzed data from 397 elderly subjects (57.7% female; mean age 74.04±10.54 years) at Baggiovara Hospital; PD patients represented 12% of the sample. Subjects underwent 24-hour Ambulatory BP Monitoring (ABPM) and orthostatic testing. Multivariate logistic regression identified independent associated factors of PD, adjusting for age, sex, BMI, and antihypertensive therapy. Results. PD patients exhibited a significantly more pronounced systolic BP drop at 1-minute orthostatism (11.46 vs 3.07 mmHg, p=0.006). A key finding was the severe impairment of circadian rhythm; an inverted dipping phenotype was significantly more frequent in the PD group (57.1% vs 28.0%, p=0.008). Consequently, PD patients showed significantly higher nocturnal mean BP compared to controls, involving both systolic (135.31 vs 128.87 mmHg, p=0.027) and diastolic values (73.80 vs 67.76 mmHg, p=0.002). Additionally, post-prandial hypotension was more frequent in PD (76.5% vs 45.6%, p=0.001). In the multivariate model, the 1-minute systolic BP drop remained significantly associated to PD (OR: 1.054; p<0.001). Conclusions. Elderly PD patients demonstrate a specific dysautonomic BP phenotype. The association between severe orthostatic drops and nocturnal hypertension—driven by an inverted dipping profile—highlights a profound failure of autonomic homeostasis independent of common geriatric confounders.

Segreteria SIGOT (2026) conducted an observational in Parkinson's disease and cardiovascular autonomic dysfunction (n=397). Parkinson's disease vs. Non-Parkinson's disease elderly controls was evaluated on Systolic blood pressure drop at 1-minute orthostatism and 24-hour ambulatory blood pressure profile (inverted dipping) (OR 1.054, p=<0.001). Parkinson's disease in elderly patients was associated with a greater 1-minute orthostatic systolic BP drop (11.46 vs 3.07 mmHg, OR 1.054, p<0.001) and inverted dipping (57.1% vs 28.0%, p=0.008).
