Non cardiac chest pain (NCCP) is defined as recurring, angina-like, retrosternal chest pain of non cardiac origin. Annual prevalence of NCCP in the general population of the western world ranges from 25-35%. Of those patients presenting to an emergency room with chest pain, a cardiac etiology is ultimately found in only 11-39%. Several conditions are associated with NCCP, with gastroesophageal reflux disease (GERD) being the most prevalent, constituting up to 60% of cases. However, NCCP is considered a disorder of heterogenous nature and several other conditions, apart of GERD, such as esophageal dysmotility and esophageal hypersensitivity have been implicated.
