Insights
Gastroesophageal reflux disease (GERD) patients exhibit significant autonomic nervous system dysfunction, particularly impaired parasympathetic activity. This study highlights a strong link between GERD and autonomic imbalance.
Area of Science:
- Cardiology
- Neuroscience
- Gastroenterology
Background:
- Gastroesophageal reflux disease (GERD) is a common condition with potential systemic implications.
- Autonomic nervous system (ANS) dysfunction has been implicated in various chronic diseases.
Purpose of the Study:
- To investigate autonomic nervous system function in patients diagnosed with GERD.
- To compare ANS parameters between GERD patients and healthy controls.
Main Methods:
- The study included 29 GERD patients and 116 healthy volunteers.
- Methods involved cardiovascular reflex testing, short-term and long-term heart rate variability (HRV) analysis, and 24-hour ambulatory blood pressure monitoring.
Main Results:
- GERD patients showed significantly higher rates of abnormal cardiovascular reflex tests and severe autonomic dysfunction (44.4% vs 7.9%).
- Reduced vagal activity (short-term HRV) and impaired parasympathetic function (long-term HRV, spectral analysis) were observed in GERD patients.
- GERD patients exhibited higher systolic and pulse blood pressure compared to controls.
Conclusions:
- Patients with GERD demonstrate altered sympathetic and parasympathetic ANS function.
- Impaired parasympathetic nervous system activity is a prominent finding in GERD patients.
Aim:
To investigate autonomic nervous function in patients with a diagnosis of gastroesophageal reflux disease (GERD).
Methods:
The investigation was performed on 29 patients (14 men), aged 18-80 years (51.14 ± 18.34), who were referred to our Neurocardiology Laboratory at the Clinical and Hospital Center "Bezanijska Kosa" with a diagnosis of GERD. One hundred sixteen healthy volunteers matched in age and sex with the examinees served as the control group. The study protocol included the evaluation of autonomic function and hemodynamic status, short-term heart rate variability (HRV) analysis, 24 h ambulatory ECG monitoring with long-term HRV analysis and 24 h ambulatory blood pressure monitoring.
Results:
Pathologic results of cardiovascular reflex test were more common among patients with reflux compared to the control group. Severe autonomic dysfunction was detected in 44.4% of patients and in 7.9% of controls (P < 0.001). Parameters of short-term analysis of RR variability, which are the indicators of vagal activity, had lower values in patients with GERD than in the control group. Long-term HRV analysis of time-domain parameters indicated lower values in patients with reflux disease when compared to the control group. Power spectral analysis of long-term HRV revealed lower low- and high-frequency values. Detailed 24 h ambulatory blood pressure analysis showed significantly higher values of systolic blood pressure and pulse pressure in the reflux group than in the control group.
Conclusion:
Patients with GERD have distortion of sympathetic and parasympathetic components of the autonomic nervous system, but impaired parasympathetic function appears more congruent to GERD.
