大多数前胸壁疼痛病人最初均认为是心脏疾病。心因型胸痛病人中多至50%可发现食管疾患。食管疾病引起胸痛的诊断中,食管运动紊乱最为常见。食管弛缓、弥漫性食管痉挛和食管收缩与扩张并存(natcracker esophagus,NE)是引起非心因型胸痛的原因。其中 NE 最常见。NE 食管测压的标准为食管蠕动顺序正常,而平均蠕动幅增大,肌肉收缩时间延长。应用降低食管收缩幅度的药物并不能改变疼痛类型。非心因性胸痛病人约有5～10%可见弥漫性食管痉挛。主要改变是吞咽食糜后,同时存在非蠕动性
Most anterior chest wall pain patients initially considered heart disease. Up to 50% of patients with chest pain due to chest pain can find esophageal disorders. Esophageal disease caused by chest pain in the diagnosis of esophageal motility disorder most common. Esophageal relaxation, diffuse esophageal spasm and esophageal contraction and expansion (natcracker esophagus, NE) is the cause of non-cardiac causes of chest pain. Among them, NE is the most common. NE esophageal manometry of the normal order of esophageal motility, and the average increase in motility amplitude, muscle contraction time. Use of drugs that reduce esophageal contractions does not change the type of pain. About 5 to 10% of patients with non-cardiac chest pain can be seen diffuse esophageal spasm. The main change is the swallowing of chyme, while there is non-motility
