~(201)铊心肌闪烁显影是检出急性心肌梗塞的敏感方法。但它也可在运动或冠状动脉痉挛引起的心肌缺血的病人中出现阳性。本文研究的目的有二:(1)不稳定型心绞痛病人~(201)铊闪烁图表现的类型;(2)~(201)铊闪烁图对较难预防或有较大倾向发生急性心肌梗塞的不稳定型心绞痛病人预测的评价。材料和方法:98例不稳定型心绞痛病人,在近次心绞痛发作后18小时内进行~(201)铊闪烁显影。不稳定型心绞痛的诊断是根据典型的心绞痛病史,短时间内(多存7～10天)发作频度的增加及疼痛程度的加重,常常在安静时或夜间发作。入院后测定了心电图和血浆酶。心肌梗塞的诊断是根据纽约心脏协会的标准。全部病人都卧床治疗。在药物难以控制心绞痛
~ (201) Thallium myocardial scintigraphy is a sensitive method to detect acute myocardial infarction. But it can also be positive in patients with myocardial ischemia caused by exercise or coronary artery spasms. The purpose of this study is twofold: (1) type of thallium scintigraphy of ~ (201) patients with unstable angina pectoris; (2) thallium ~ (201) scintigraphy is more difficult to prevent or have a greater tendency to acute myocardial infarction Predictors of Unstable Angina Patients. MATERIALS AND METHODS: Ninety-nine patients with unstable angina pectoris developed ~ (201) Thallium scintigraphy within 18 hours after the last episode of angina pectoris. The diagnosis of unstable angina pectoris is based on a typical history of angina, an increase in the frequency of seizures within a short period of time (7 to 10 days of storage), and an increase in the degree of pain, often in sedation or at night. After admission, the electrocardiogram and plasma enzyme were measured. Myocardial infarction is diagnosed according to the New York Heart Association standards. All patients are bedridden. It is difficult to control the angina in the medicine
