Why the study?
The study aimed to investigate the relationship between short-term blood pressure variability, autonomic function measured by heart rate variability, and complex arrhythmias in hypertensive patients.
Does elevated short-term blood pressure variability correlate with cardiac autonomic dysfunction and complex arrhythmias in patients with primary hypertension?
Population
198 middle-aged and elderly patients with primary hypertension
Comparison
Patients stratified by tertiles of 24-h systolic blood pressure variability
Design
Retrospective observational study
Key result
High 24-h systolic blood pressure variability was associated with a higher incidence of complex arrhythmias compared to low variability (71.2% vs 40.9%) in hypertensive patients.

May flag high-risk hypertensives for closer monitoring; leaves open whether BPV modification reduces arrhythmias.
Observational (n=198)
Does elevated short-term blood pressure variability correlate with cardiac autonomic dysfunction and complex arrhythmias in patients with primary hypertension?
Absolute Event Rate: 71.2% vs 40.9%
Increased short-term blood pressure variability in hypertensive patients is independently associated with impaired cardiac autonomic function and a higher prevalence of complex arrhythmias.
You et al. (2026) conducted an observational in primary hypertension (n=198). High 24-h systolic blood pressure variability vs. Low 24-h systolic blood pressure variability was evaluated on incidence of complex arrhythmias. High 24-h systolic blood pressure variability was associated with a higher incidence of complex arrhythmias compared to low variability (71.2% vs 40.9%) in hypertensive patients.
