本研究对11例正常人及21例早期冠心病患者,进行大剂量潘生丁——超声心动图(大剂量 DET)定量检测室壁运动,并与核素心肌显像的运动靶心图定量对比。结果发现21例患者平静超声心动图,8例(38.1%)检出区域性室壁运动异常(RWMA),潘生丁负荷后20例(95.24%)检出 R WMA。21例患者共420个节段中,大剂量 DET 定量和运动靶心图定量节段检出率高度一致,表明大剂量 DET 定量检测室壁运动异常为早期诊断冠心病的方法。
In this study, 11 normal subjects and 21 patients with early-stage coronary heart disease underwent high-dose dipyridamole-echocardiography (high-dose DET) for quantification of ventricular wall motion and quantitative comparison with radionuclide myocardial imaging. Results Echocardiography was found in 21 patients. Regional wall motion abnormalities (RWMA) were detected in 8 cases (38.1%) and R WMA in 20 cases (95.24%) after dipyridamole stress. Of the 420 patients in all 21 segments, the quantitative detection of DET at large doses and the quantitative detection of moving bull’s eye diagrams were highly consistent, indicating that high-dose DET quantitative detection of abnormal wall motion is an early diagnosis of coronary heart disease.
