Abstract

Introduction: The cardiovascular risk of Parkinson's Disease (PD) patients is uncertain. Blood pressure variability (BPV) has been associated with cardiovascular and mortality outcomes. We aimed to evaluate blood pressure variability, as a marker of cardiovascular risk, in patients with PD and matched community controls.

Methods: Cross-sectional case-control study was performed. All subjects included in the analysis were clinically evaluated and performed a 24 h ambulatory blood pressure monitoring. BPV was assessed using standard deviations (SDs) of the systolic blood pressure (SBP) and diastolic blood pressure (DBP) for each period - 24 h, daytime, and night-time.

Results: The study included 204 participants, 102 in each group. Mean age 66 years old and 59% man. Most PD patients presented mild symptoms (mean Hoehn&Yahr 2.04). Daytime BPV was significantly higher in PD patients (SD SBP 14.1 mmHg vs 12.96 mmHg and SD DBP 9.39 mmHg vs 8.29 mmHg), but 24 h and night-time BPV were non-significantly increased. PD patients present non-significant higher night-time SBP (114 mmHg vs 110 mmHg) as well as higher frequency of non-dippers or reverse dippers BP profiles (51% vs 36%).

Conclusion: Our exploratory study suggests that PD patients may present a higher blood pressure variability, which may translate in an increased cardiovascular risk. However, further studies are needed to confirm this hypothesis and causality.

Keywords: Blood pressure variability; Cardiovascular risk; Parkinson’s disease.
