对不能运动的冠心病人静(脉)注(射)潘生丁铊心肌显像是发现隐匿性心肌缺血的有效试验,但在无症状的冠心病人中还无这方面的研究。这篇报告的目的是检查在无症状性冠心病人中静注潘生丁铊心肌显像的预后价值,决定可逆性铊显影缺损是否与临床的不良后果有关,可逆缺损是否指示隐匿性心肌缺血。方法 107名无症状的病人,33名以往有心肌梗塞。96名病人作冠状动脉造影检查。早晨病人空腹平卧,按0.56mg/kg 的剂量静注潘生丁,4分钟后静注2mci~(201)铊,5分钟内依次获取45°左前斜位,正前位和左侧位的影像,4小时后获取再分布铊影像。异常铊影像分为可逆的、固定的、混合性的铊影像缺损,后者指可逆的与固定的缺损同时存在于不同的节段上。隐匿性心肌缺血是指存在
In patients with coronary heart disease can not exercise static (pulse) injection (injection) dipyridamole thallium myocardial imaging is an effective test to find occult myocardial ischemia, but asymptomatic coronary heart disease in patients with no such studies. The purpose of this report is to examine the prognostic value of intravenous dipyridamole thalidomide in asymptomatic patients with coronary heart disease and to determine whether reversible thalidomide defects are associated with adverse clinical outcomes and whether reversible defects indicate occult myocardial ischemia. Methods 107 asymptomatic patients and 33 previously had myocardial infarction. 96 patients for coronary angiography. Morning patients with fasting supine, according to 0.56mg / kg dose of intravenous injection of dipyridamole, 4 minutes after intravenous infusion of 2mci ~ (201) thallium within 5 minutes were followed by 45 ° left oblique, anterior and left position of the image, 4 hours later redistribution of thallium images obtained. Abnormal thallium image is divided into reversible, fixed, mixed Thallium image defects, the latter refers to the reversible and fixed defects exist in different segments at the same time. Occult myocardial ischemia is the presence
