Noncardiac chest pain of esophageal origin in patients with and without coronary artery disease.

Abstract
Non-cardiac chest pain is a frequent finding in patients admitted to emergency departments, and it has been shown that many of these patients may have an esophageal cause for their pain. However, little data are available on patients primarily referred to the cardiology unit, and especially those with coronary artery disease. The purpose of this study was to assess the role of esophageal dysfunction in chest pain patients with and without coronary artery disease. Eighty-one patients referred from a cardiology unit for chest pain and no myocardial infarction entered the study. Sixty-one patients had no evidence of coronary artery disease, whereas 20 had coronary artery disease with chest pain at rest. After the cardiological evaluation, the patients underwent esophageal function testing by means of upper endoscopy, manometry, and 24-hour pH-monitoring. Overall, 10% of patients (2.5% in the coronary artery disease group) had evidence of endoscopic esophagitis, 46% of esophageal motor disorders (12% in the coronary artery disease group), and 10% abnormal pH-monitoring (1% in the coronary artery disease group). We report that the esophagus might be responsible for non-cardiac chest pain in patients with and without coronary artery disease. In our experience, esophageal motor disorders, and not an increased acid reflux, are the abnormalities most commonly found in these patients.
