Non-cardiac chest pain: a variant on Murphy's sign

Chest pain of esophageal origin

Chest pain of esophageal origin is the most common atypical/extraesophageal manifestation of gastroesophageal reflux disease (GERD). We are increasingly recognizing the important role of the cardiologist in making the diagnosis. Studies continue to focus on the mechanisms of pain in this challenging group of patients. Factors that determine the development and persistence of visceral hypersensitivity are currently under investigation. Invasive diagnostic studies have been replaced by therapeutic trials or empirical therapies. Proton pump inhibitors have been demonstrated to be the most effective treatment for GERD-related noncardiac chest pain (NCCP). Pain modulators remain the primary therapy for non-GERD-related NCCP. Sertraline is the first selective serotonin reuptake inhibitor to demonstrate a significant improvement in chest pain symptoms.
