探讨非心源性胸痛（NCCP）患者中食道患病率情况及其临床特点。

选取2018年1月至2019年4月在新疆维吾尔自治区人民医院因NCCP就诊的85例患者为研究对象。其中，男性45例（52.94%），平均年龄为41.2±12.4；女性为40例（47.06%），平均年龄为43.3±10.9。对所有的研究对象进行上消化道内镜检查、高分辨率食道测压和24 h动态食管pH监测。均值、标准差（SD）、范围、频率、百分比（如果连续和正态分布）和比例（如果分类）进行描述性统计；符合正态分布的计量资料均以（

NCCP患者中最常见的症状为酸反流43.53%，吞咽困难31.76%，烧心24.71%。上消化道内镜检查异常者占31.76%，高分辨率食管测压异常者占67.06%，动态pH监测异常者占34.76%。上消化道内镜检查联合24 h pH监测确定胃食管反流病（GERD）的患病率为42.36%。基于食管测压检查23.53%的NCCP患者无效食管动力是NCCP最常见的病因。

通过分析食管源性引起NCCP的病因，有助于临床医生排除其它导致胸痛的高危因素，并为其诊疗提供适当的治疗方案。

To investigate the prevalence and clinical characteristics of esophagus in patients with non-cardiac chest pain (NCCP).

Patients who diagnosed with NCCP from January 2018 to April 2019 in Xinjiang Uygur Autonomous Region People's Hospital were selected as the study subjects. Detailed medical history, physical examination, upper gastrointestinal endoscopy, high resolution esophageal manometry and 24 h dynamic esophageal pH monitoring were performed on all subjects.

The total number of subjects was 85, of which male 45(52.94%), with an average age of 41.2±12.4 years;female was 40 (47.06%), with an average age of 43.3±10.9 years. The most common symptoms in NCCP patients were acid reflux 43.53%, dysphagia 31.76%, heartburn 24.71%. Endoscopic abnormalities of upper gastrointestinal tract accounted for 31.76%, esophageal manometry abnormalities accounted for 67.06%, and dynamic pH monitoring abnormalities accounted for 34.76%. The prevalence of GERD was 42.36% determined by upper gastrointestinal endoscopy combined with 24 h pH monitoring. According to manometric results, ineffective esophageal motility in 23.53% of NCCP patients was the most common cause of NCCP.

By analyzing the causes of esophagogenous NCCP, it is helpful for clinicians to exclude other high-risk factors leading to chest pain and to provide appropriate treatment for their diagnosis and treatment
