Stress echocardiography has a high accuracy for the detection of coronary artery disease. Additionally, it provides clinically useful prognostic information, such as resting left ventricular function, myocardial viability, stress-induced ischemia, vascular extent of wall motion abnormalities, and changes in end-systolic volume and ejection fraction with stress.
The timing, extent, and severity of the stress-induced wall motion abnormalities are important determinants of long-term prognosis. Previous studies have shown the efficacy of stress echocardiography in predicting long-term cardiac events in mixed patient groups and the value of this test in selected patient subsets.
This review attempts to define the role of stress echocardiography for prognostication in coronary artery disease, pointing out the ability of this technique to identify low-risk and high-risk subsets among patients with known or suspected coronary artery disease and thus guide patient management decisions.
负荷超声心动图在检测冠状动脉疾病方面具有较高的准确性。此外,它还能提供临床上有用的预后信息,如静息左心室功能、心肌存活性、负荷诱发的心肌缺血、室壁运动异常的血管范围以及负荷时收缩末期容积和射血分数的变化。
负荷诱发的室壁运动异常的时间、范围和严重程度是长期预后的重要决定因素。既往研究已表明负荷超声心动图在预测混合患者群体的长期心脏事件方面的有效性以及该检查在特定患者亚组中的价值。
本综述试图明确负荷超声心动图在冠状动脉疾病预后评估中的作用,指出该技术在已知或疑似冠状动脉疾病患者中识别低风险和高风险亚组的能力,从而指导患者管理决策。
