Chest pain in patients with normal coronary arteries. A new look at potential causes
1Division of Gastroenterology, University of Missouri-Columbia School of Medicine 65212.
Insights
Recurrent chest pain with normal coronary arteries is challenging. Gastroesophageal reflux disease is a key treatable cause, offering relief for debilitated patients.
Area of Science:
- Cardiology
- Gastroenterology
- Psychiatry
Background:
- Recurrent chest pain with normal coronary arteries presents a diagnostic challenge.
- Patients often experience significant debilitation and frequent emergency department visits.
- Cardiac morbidity and mortality are low, but quality of life is impaired.
Purpose of the Study:
- To identify key causes of chest pain in patients with unobstructed coronary arteries.
- To highlight the importance of gastroesophageal reflux disease (GERD) as a treatable etiology.
- To guide clinical evaluation and management strategies.
Main Methods:
- Review of recent literature on non-cardiac chest pain.
- Analysis of potential contributing factors including microvascular angina, esophageal disorders, and panic disorder.
- Emphasis on diagnostic and therapeutic approaches for GERD.
Main Results:
- Microvascular angina, esophageal disorders (GERD, dysmotility), and panic disorder are implicated.
- GERD is identified as a common, diagnosable, and treatable cause.
- Effective management of GERD can alleviate symptoms and improve patient function.
Conclusions:
- GERD should be strongly considered in the differential diagnosis of non-cardiac chest pain.
- Timely diagnosis and treatment of GERD can reduce patient debilitation and healthcare utilization.
- A multidisciplinary approach may be beneficial for complex cases.
Abstract:
Recurrent chest pain in patients with normal coronary arteries is a difficult clinical problem. Although long-term studies have shown that these patients have an excellent prognosis in terms of cardiac morbidity and mortality, many patients remain physically debilitated and continue to visit emergency departments. Recent information suggests that microvascular angina, esophageal disorders (including reflux disease and dysmotility), and panic disorder may be important causes of pain in such patients. It is particularly important to consider the diagnosis of gastroesophageal reflux disease, which is easier to diagnose and treat than most other causes of recurrent chest pain.
