作者将传统食管试验与24小时食管 pH值监测进行对比试验,旨在评价两种方法鉴别食管源性胸痛的诊断价值。病人与方法 100例心绞痛样胸痛患者,经心脏病工程师评定后转入食管实验室进行食管源性胸痛的前瞻性研究。男43例,女57例,平均年龄50岁(22～69)。所有患者胸痛时 ECG均无缺血性 ST 段改变和心律失常。66例患者曾作心导管检查:48例冠脉造影正常,18例为非阻塞性病变(冠脉狭窄<50%)。本组74例患者做过食管检查,38例内镜检查正常,33例钡餐透视消化道无明显病变,3例经内镜确诊为糜烂性食管炎;其余26例未作食管检查。全部 The author compared the traditional esophageal test with the 24-hour esophageal pH monitoring to evaluate the diagnostic value of the two methods in differential diagnosis of esophageal chest pain. Patients and Methods 100 cases of angina pectoris patients were transferred to esophageal laboratory for prospective study of esophageal chest pain after assessment by a heart disease engineer. 43 males and 57 females, average age 50 years (22-69). All patients with chest pain ECG no ischemic ST segment changes and arrhythmia. Sixty-six patients underwent cardiac catheterization: 48 were normal coronary angiography and 18 were non-obstructive (coronary stenosis <50%). The group of 74 patients had esophageal examination, 38 cases of endoscopy was normal, 33 cases of barium meal digestive tract no obvious lesions, 3 cases of endoscopic diagnosis of erosive esophagitis; the remaining 26 cases without esophageal examination.
