Resting echocardiography is the most important tool for diagnosing valvular heart disease. However, treatment planning in valvular heart diseases may require additional information in some patients, particularly asymptomatic patients with severe valve disease or symptomatic patients with moderate disease. Stress echocardiography provides invaluable information in these situations and aids decision making. Stress echocardiography is performed using either physical stress or dobutamine stress and various valve parameters are monitored during the stress. Further, the ventricular performance, which is an important determinant of outcome in valve disease is also closely monitored during stress which helps immensely in planning the intervention. Lastly, possibility of associated coronary artery disease can also be evaluated, especially in the elderly. This article discusses the role of stress evaluation in assessment of valve disease in the commonly encountered clinical situations.
静息超声心动图是诊断心脏瓣膜病最重要的工具。然而，在某些患者中，尤其是患有严重瓣膜病的无症状患者或患有中度疾病的有症状患者，心脏瓣膜病的治疗计划可能需要更多信息。负荷超声心动图在这些情况下提供了宝贵的信息并有助于决策。负荷超声心动图可通过体力负荷或多巴酚丁胺负荷来进行，在负荷过程中监测各种瓣膜参数。此外，心室功能是瓣膜病预后的重要决定因素，在负荷过程中也会密切监测，这对干预计划有极大帮助。最后，还可以评估是否存在相关冠状动脉疾病的可能性，尤其是在老年人中。本文讨论了负荷评估在常见临床情况下瓣膜病评估中的作用。
