心绞痛而冠状动脉造影正常的病人,与示有明显冠状动脉闭塞者不同,其预后较佳。作者报告37例(男21例、女16例)选择性冠状动脉造影无异常,但有心肌缺血的客观指标(心电图及/或心肌代谢检查),以及明显心绞痛综合症的患者。在观察期中,全部病例均有符合心绞痛综合症的发作性胸部不适。主诉符合Hurst和Logue标准者列为典型心绞痛,胸痛综合症出现的部位、间期或发作与劳累及紧张的关系不完全符合Hurst和Logue的标准者,则列为不典型心绞痛。血液动力学及心肌代谢的研究系在空腹下进行,在测定对照期心率、左室压力及心排出量后,14例作心房调搏负荷试验,于调搏前及调搏时分别抽取冠状静脉窦血及动脉血以测定乳
Angina and coronary angiography in patients with normal, and showed obvious coronary artery occlusion is different, the prognosis is better. The authors reported 37 patients (21 males and 16 females) who had no abnormal coronary angiography but had objective indicators of myocardial ischemia (electrocardiogram and / or myocardial metabolism) and those with overt angina pectoris syndrome. During the observation period, all patients had episodic chest discomfort that conformed to angina pectoris syndrome. The main complaint of Hurst and Logue standards were classified as typical angina, chest pain syndrome appears in the site, interval or attack and exertion and tension are not fully meet the criteria of Hurst and Logue, was classified as atypical angina. The study of hemodynamics and myocardial metabolism was carried out in fasting. Fourteen patients underwent atrial pacing load test after determination of control heart rate, left ventricular pressure and cardiac output.
