1. Selective cine coronary arteriography: correlation with clinical findings in 1000 patients;Proudfit, W.L.; Shirey, E.K.; Stones, F.M.;Circulation; Alternatively, symptoms of an oesophageal disorder may occur frequently in the community but with the majority of sufferers not seeking help for their problem as is seen in subjects with symptoms of bowel dysfunction.12'13 In this situation the independent occurrence of a psychiatric disorder may bring the patient to the attention of their doctors at a stage where their symptoms alone would not have done so. Such selective referral would lead to a spuriously high association between psychiatric illness and oesophageal motility disorders in subjects studied in the outpatient department
2. These results confirm the association between chest pain, psychiatric morbidity and negative investigations for coronary disease, but this group is not diagnostically homogeneous. The clinician should be particularly alert for psychiatric illness in those subsequently shown to have oesophageal disorders and in those without denionstrable abnormalities. It remains to be determined whether psychiatric treatment of such patients could relieve their symptoms or even possibly alter motility patterns
