Two-dimensional echocardiographic monitoring during catecholamine infusion has shown promise as a safe and accurate method for detection of coronary artery disease. The clinical application of catecholamine stress echocardiography has been facilitated by the development of digital image processing techniques. The sensitivity of this method of stress testing has been improved by drug infusion protocols that are designed to maximize myocardial stress. Recent investigations have demonstrated the value of dobutamine stress echocardiography for detection of multivessel disease following myocardial infarction and for assessment of cardiac risk before noncardiac surgery. Evaluation of changes in wall motion and thickening that occur during low dose dobutamine infusion may enable detection of viable myocardium after thrombolytic treatment of acute myocardial infarction. Compared to alternative noninvasive diagnostic methods, catecholamine stress echocardiography permits continuous acquisition of high-quality information on regional and global systolic function. This and other advantages have prompted the search for broader applications of this technique.
在儿茶酚胺输注过程中进行二维超声心动图监测，已显示出有望成为一种检测冠状动脉疾病的安全且准确的方法。数字图像处理技术的发展推动了儿茶酚胺负荷超声心动图的临床应用。旨在使心肌应激最大化的药物输注方案提高了这种负荷试验方法的敏感性。最近的研究已证明多巴酚丁胺负荷超声心动图对于检测心肌梗死后的多支血管病变以及评估非心脏手术前的心脏风险具有价值。评估低剂量多巴酚丁胺输注期间发生的室壁运动和增厚变化，可能有助于在急性心肌梗死溶栓治疗后检测存活心肌。与其他非侵入性诊断方法相比，儿茶酚胺负荷超声心动图能够持续获取有关局部和整体收缩功能的高质量信息。这一优势及其他优点促使人们探寻该技术更广泛的应用。
