Many patients present with chest pain and are subsequently found to have normal coronary angiography; investigation of these patients frequently stops once coronary artery disease has been ruled out. It is now clear that considerable morbidity may be associated with failure to make a definite diagnosis in these patients, and that efforts to identify a cause for the pain should continue within appropriate limits. This paper presents the evidence in support of an esophageal cause of non-cardiac angina. The authors emphasize the difficulty in distinguishing between cardiac and esophageal angina on the basis of clinical history and suggest an approach to investigation.
许多患者表现为胸痛，随后冠状动脉造影显示正常；一旦排除冠状动脉疾病，对这些患者的检查通常就会停止。现在很清楚，在这些患者中未能做出明确诊断可能会伴有相当高的发病率，并且在适当范围内继续努力寻找疼痛原因是有必要的。本文提供了支持非心源性心绞痛由食管引起的证据。作者强调根据临床病史区分心脏性和食管性心绞痛存在困难，并提出了一种检查方法。
