静注潘生丁~(201)铊心肌显像在年龄<70岁的冠心病人中的预后价值已被证实,但在老年病人中尚未见大系列的研究报告。此项研究探讨潘生丁~(201)铊显像在年龄>70岁的老年病人中预测心脏性死亡及非致命性心肌梗塞的价值。方法病人348例,其中207例有症状,141例无症状。52％的无症状病人被证实患有冠心病。潘生丁剂量0.56mg/kg体重,静注4分钟,病人随后作腿部摇摆运动6分钟。在运动后4分钟静注2mci的~(201)铊。显像的左室节段按正常、可逆性缺损或固定缺损记录。可逆性缺损、固定性及混合性(可逆加固
The prognostic value of intravenous dipyridamole ~ (201) thallium myocardial imaging in patients with coronary heart disease <70 years of age has been demonstrated, but no large series of studies have been reported in elderly patients. This study explored the value of dipyridamole ~ (201) thallium imaging in predicting cardiac death and non-fatal myocardial infarction in elderly patients> 70 years of age. Methods 348 patients, of which 207 cases of symptoms, 141 cases of asymptomatic. Fifty-two percent of asymptomatic patients were confirmed to have coronary heart disease. Dipyridamole dose 0.56mg / kg body weight, intravenous infusion of 4 minutes, the patient subsequently for leg swinging exercise 6 minutes. 2 mci of ~ (201) thallium was intravenously injected 4 minutes after exercise. Imaging of the left ventricular segment by normal, reversible defect or fixed defect records. Reversible defects, fixation and mixed (reversible reinforcement
