Acid reflux is a common and potentially treatable cause of noncardiac chest pain. Traditional esophageal tests usually miss this diagnosis. Twenty-four-hour esophageal pH monitoring with symptom correlation is the single best test for evaluating patients with noncardiac chest pain.

Gastroesophageal reflux disease is a common, treatable cause of chest pain in patients with coronary artery disease who have atypical symptoms and remain symptomatic despite aggressive antianginal therapy. Combined Holter and 24-hour esophageal pH studies are complementary investigations for elucidating the cause of chest pain in these patients.
