title: Noncardiac chest pain: epidemiology, natural history, health care seeking, and quality of life.
abstract: The epidemiology of NCCP is poorly described, and the available data are conflicting. Population-based studies on the prevalence of NCCP are rare; most studies have been hospital based. According to the limited studies available, the annual prevalence of NCCP is approximately 25%. Despite this significant burden, the impact and natural history of NCCP in the community has not been adequately explored. NCCP is presumed to bea heterogeneous condition. Hospital-based studies have suggested that GERD, esophageal spasm, psychiatric disease (including panic attacks), and musculoskeletal pain explain many cases of NCCP. However, unrecognized coronary artery disease and microvascular angina (cardiac syndrome X)also explain an unknown proportion of cases in the general population.Current studies suggest that NCCP is common in the general population and significantly affects QOL, yet only a minority seeks medical attention.The epidemiology of NCCP requires further study in the general population and in those attending the Emergency Department.
