In 100 successive patients with normal coronary arteriography performed for spontaneous precordial chest pain, a Methergine test was performed to induce coronary artery spasm, in addition to esophageal manometry, and an angiographic and echocardiographic study of the left ventricle. These tests were all normal in 39 patients, whereas the remaining 61 patients had pain due to coronary artery spasm (14 times), a non-coronary artery cardiopathy (16 times) (hypertrophic cardiomyopathy or mitral valve prolapse), or esophageal dyskinesia (35 times). The latter was an isolated finding 29 times, was associated 3 times with coronary artery spasm, and 3 times with non-coronary artery cardiopathy.
在100例因自发性心前区胸痛接受冠状动脉造影结果正常的连续患者中，除了进行食管测压以及对左心室进行血管造影和超声心动图研究外，还进行了麦角新碱试验以诱发冠状动脉痉挛。这些检查在39例患者中全部正常，而其余61例患者的疼痛原因分别为冠状动脉痉挛（14次）、非冠状动脉性心脏病（16次）（肥厚型心肌病或二尖瓣脱垂）或食管运动障碍（35次）。后者单独出现29次，与冠状动脉痉挛同时出现3次，与非冠状动脉性心脏病同时出现3次。
