[Chest pain - not always the heart! Clinical impact of gastrointestinal diseases in non-cardiac chest pain]. / Brustschmerz - nicht immer das Herz! Klinische Bedeutung gastrointestinaler Erkrankungen beim nicht-kardialen Thoraxschmerz.

ABSTRACT

Non cardiac chest pain (NCCP) are recurrent angina pectoris like pain without evidence of coronary heart disease 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. Especially gastroenterological expertise is required because in 50 - 60 % of cases gastroesophageal reflux disease (GERD), in 15 - 18 % hypercontractile esophageal motility disorders with nutcracker, jackhammer esophagus or distal esophageal spasmus or achalasia and in 32 - 35 % other esophageal alterations (e. g. infectious esophageal inflammation, drug-induced ulcer, rings, webs, eosinophilic esophagitis) as cause of chest pain may be detected. This implicates that regular interdisciplinary round wards and management of chest pain units are mandatory.
