本文对75例可疑冠心病而静息心电图正常的患者进行了前瞻性相关研究,以比较运动超声心动图和~(99m)T MIBI检出冠心病的相对价值。运动超声心动图和SPECT在同一次症状限制性活动平板试验中进行。运动后,新出现的室壁运动异常和/或可逆性灌注缺损,分别被视为运动超声心动图和SPECT试验阳性。这二种诊断试验的结果均与冠脉造影比较。
In this paper, 75 patients with suspected coronary heart disease and normal resting ECG were prospectively studied to compare the relative value of exercise echocardiography and ~ (99m) T MIBI detection of coronary heart disease. Exercise echocardiography and SPECT were performed in the same symptom-limited activity plate test. After exercise, newly developed wall motion abnormalities and / or reversible perfusion defects are considered as motor echocardiography and SPECT test positive, respectively. The results of these two diagnostic tests are compared with coronary angiography.
