Although a small proportion of such patients with ST segment depression may have underlying cardiac disease,6 most have atypical pain and normal exercise tests.7 ,8 In these patients, a benign non-cardiac cause is likely. Thus about 50% of all patients with normal coronary anatomy and non-cardiac chest pain have oesophageal reflux or motility disorders,4 approximately 60% have evidence of breathing disorders,7 ,8 and 60% a psychiatric disorder.4 ,9 Psychiatric causes include panic, major depression, and health anxiety (hypochondriasis-like and other so called somatoform disorders). However, the clinical significance of oesophageal and respiratory abnormalities is not straightforward as they often do not coincide with pain.10 ,11 Furthermore, the response to specific treatment is variable4 raising the possibility that these abnormalities are coincidental rather than causative.Half of the patients with chest pain and normal angiographic anatomy have two or more of the aforementioned conditions (oesophageal, respiratory, or psychiatric abnormalities). … ER -
