Key result

Gastroesophageal reflux disease was associated with a significantly higher prevalence of severe autonomic dysfunction compared to healthy controls (44.4% vs 7.9%, p<0.001).

Why the study?

Do patients with gastroesophageal reflux disease have impaired cardiac autonomic function compared to healthy controls?

Population

145 participants, including 29 patients with a diagnosis of gastroesophageal reflux disease and 116 age- and…

Case-control

Overview

GERD patients exhibit vagal impairment on HRV testing; leaves open whether autonomic assessment should inform management.

Type

Observational (n=145)

Multicenter

No

Structured PICO

Do patients with gastroesophageal reflux disease have impaired cardiac autonomic function compared to healthy controls?

P
Population
145 adults (29 with GERD and 116 healthy matched controls) evaluated for autonomic nervous function using cardiovascular reflex tests, heart rate variability, and ambulatory blood pressure monitoring.
C
Comparator
Healthy volunteers matched in age and sex
O
Outcome
Autonomic function, hemodynamic status, short-term heart rate variability (HRV), long-term HRV via 24 h ambulatory ECG, and 24 h ambulatory blood pressuresurrogate

Main Result

Absolute Event Rate: 44.4% vs 7.9%

p-value: p=<0.001

Patients with GERD exhibit significant cardiac autonomic dysfunction, particularly impaired parasympathetic function, compared to healthy controls.

Limitations

  • Small sample size
  • Cross-sectional design limits causal inference
  • Missing data for some autonomic tests

Milovanović et al. (2015) conducted an observational in Gastroesophageal reflux disease (GERD) (n=145). Gastroesophageal reflux disease vs. Healthy volunteers was evaluated on Severe autonomic dysfunction (p=<0.001). Gastroesophageal reflux disease was associated with a significantly higher prevalence of severe autonomic dysfunction compared to healthy controls (44.4% vs 7.9%, p<0.001).
