核素运动负荷心肌灌注显像诊断冠心病

Ridionulide Exercise Myocardial Perfusion Imaging in the Diagnosis of Coronary Artery Disease

目的：探讨三种非侵入性冠心病诊断方法的利弊。材料和方法：对５７例冠心病患者进行运动负荷心肌断层显像（ＥＣＴ），同时与动态心电图（ＤＣＧ）、心电图运动试验（ＴＥＴ）进行对比。结果：运动负荷显像示５２例（９１．２％）呈一个或二个以上部位的心肌缺血改变；ＤＣＧ示４１例（７１．９％）心肌缺血，其中２８例伴有心律失常（４９．１％）；ＴＥＴ示３１例（５４．４％）心肌缺血。三种方法比较，对心肌缺血的检出以核素运动负荷心肌断层显像最高。结论：在病人难以接受冠脉造影时，ＥＣＴ结合ＴＥＴ或ＤＣＧ试验将提高诊断冠心病的可靠性。

Purpose:To evaluate three noninvasive methods in detection of coronary artery disease(CAD).Materials and Methods:Radionuclide exercise myocardial perfusion imaging and holter monitoring and treadmill exercise testing(TET)were compared in 57 cases of CAD.Results:One or more than two ischemic regions were found in 52(91.2%)patients of the 57 with Exercise stress imaging.Holter showed ischemia in 41(71.9%)cases with arrhythmia in 28.There were ischemia in 31(54.4%)cases with TET.Compared three methods,Radiouclide exercise myocardial perfusion imaging has higher sensitivity in the detection of ischemia.Conclusion:Combining different methods for diagnosis of CHD showed more reliability when the patient can't accept coronary arteriography.
