[Oesophageal function in patiensts with angina (author's transl)]

|July 30, 1976
Summary
Patients with angina showed abnormal esophageal acid clearance and low lower esophageal sphincter pressure, similar to reflux disease patients. However, hiatal hernia and reflux symptoms were comparable to healthy individuals.
Area of Science:
- Gastroenterology
- Cardiology
Background:
- Angina pectoris is often associated with gastrointestinal symptoms.
- Distinguishing cardiac pain from esophageal dysfunction is clinically important.
Purpose of the Study:
- To compare esophageal functions in patients with angina, reflux disease, and healthy controls.
- To investigate the relationship between esophageal motility and angina.
Main Methods:
- Esophageal manometry and acid clearance tests were performed.
- Patients with angina (n=18), reflux disease (n=29), and healthy volunteers (n=13) were studied.
Main Results:
- Abnormal acid clearance was observed in both angina (88 ± 46 swallows) and reflux disease patients (97 ± 45 swallows).
- Lower esophageal sphincter pressure was reduced in angina patients (13 ± 8 mm Hg).
- Hiatal hernia and reflux provocation test results did not differ between angina patients and healthy controls.
Conclusions:
- Esophageal dysfunction, including impaired acid clearance and low LES pressure, is present in angina patients.
- These findings suggest a potential overlap in pathophysiology or referred symptoms between cardiac and esophageal conditions.
