To assess the feasibility, safety and usefulness of dobutamine stress echocardiography for the detection of coronary artery disease we evaluated 63 patients (45 men, 18 women) with effort chest pain. All patients underwent electrocardiographic submaximal bicycle exercise testing and 2-dimensional echocardiography during dobutamine infusion. Echocardiographic dobutamine test response was considered positive when new wall motion abnormalities were observed during dobutamine infusion. Sensitivity and specificity of electrocardiographic exercise test and dobutamine stress echocardiography were assessed in 25 patients who underwent selective coronary angiography. The sensitivity and specificity of dobutamine stress echocardiography, respectively 93.3% and 83.3%, were higher than those of exercise electrocardiography. 2-dimensional echocardiography during dobutamine infusion is a well tolerated, feasible and effective test for detecting coronary artery disease.
为评估多巴酚丁胺负荷超声心动图检测冠状动脉疾病的可行性、安全性及实用性，我们对63例（45例男性，18例女性）劳力性胸痛患者进行了评估。所有患者在多巴酚丁胺输注期间均接受了心电图次极量踏车运动试验和二维超声心动图检查。当在多巴酚丁胺输注期间观察到新的室壁运动异常时，超声心动图多巴酚丁胺试验反应被认为是阳性。在25例接受选择性冠状动脉造影的患者中评估了心电图运动试验和多巴酚丁胺负荷超声心动图的敏感性和特异性。多巴酚丁胺负荷超声心动图的敏感性和特异性分别为93.3%和83.3%，高于运动心电图。多巴酚丁胺输注期间的二维超声心动图是一种耐受性良好、可行且有效的检测冠状动脉疾病的方法。
