Stress echocardiography is the combination of 2D echocardiography with a physical, pharmacological or electrical stress. The diagnostic end point for the detection of myocardial ischemia is the induction of a transient worsening in regional function during stress. Stress echocardiography provides similar diagnostic and prognostic accuracy as radionuclide stress perfusion imaging but at a substantially lower cost, without environmental impact and with no biohazards for the patient and the physician. In spite of its dependence upon operator's training, it is the best possible choice to achieve the still elusive target of sustainable cardiac imaging in the field of noninvasive diagnosis of coronary artery disease.
负荷超声心动图是二维超声心动图与体力、药物或电负荷的结合。检测心肌缺血的诊断终点是负荷期间局部功能的短暂恶化。负荷超声心动图提供与放射性核素负荷灌注成像相似的诊断和预后准确性，但成本显著更低，对环境无影响，且对患者和医生无生物危害。尽管它依赖于操作者的培训，但它是在冠状动脉疾病无创诊断领域实现可持续心脏成像这一仍难以捉摸的目标的最佳选择。
