Non cardiac chest pain (NCCP) are recurrent angina pectoris like pain without evidence of coronary heart diesease in conventional diagnostic evaluation. The prevalence of NCCP is up to 70% and may be detected in this order at all levels of the medical health care system (general practitioner, emergency department, chest pain unit, coronary care). Reduction of quality of life in NCCP is comparable, partially even higher compared to cardiac chest pain. Reasons for psychological strain are symptom recurrence in app. 50%, nonspecific diagnosis with resulting uncertainty and insufficient integration of other medical disciplines in diagnostic work-up. Managing of patients with NCCP has to be interdisciplinary because non cardiac causes of chest pain may be found frequently. This are musculosceletal in app. 40%, gastrointestinal in app. 20%, psychiatric in app. 10% and pulmonary and mediastinal diseases in app. 5% of cases. Also gastroenterological expertise is required because here gastroesophageal reflux disease (GERD) in app. 60%, hypercontractile esophageal motility disorders with nutcracker, jackhammer esophagus or distal esophageal spasmus or achalasia in app. 20% and other esophageal alterations (e. g. infectious esophageal inflammation, drug-induced ulcer, rings, webs, eosinophilic esophagits) in app. 30% of cases may be detected as cause of chest pain may. This implicates that regular interdisciplinary round wards and interdisciplinary management of chest pain units are mandatory.
