In this review, we make a comprehensive summary of exercise stress echocardiography in hypertrophic cardiomyopathy (HCM) and practical tips used in our hospital. The main objective of performing exercise stress echocardiography in patients with HCM is to evaluate left ventricular outflow tract obstruction, mitral regurgitation, left ventricular asynergy, and diastolic function during exercise. There are limitations to the explanations that can be provided for exertional symptoms when resting echocardiography is performed in patients with HCM. In contrast, exercise stress echocardiography causes the manifestation of findings that are latent at rest, which possibly provides the elucidation of symptom etiology. In this article, we focus on the usefulness of exercise stress echocardiography in HCM.
在本综述中，我们全面总结了肥厚型心肌病（HCM）运动负荷超声心动图检查及我院所采用的实用技巧。对HCM患者进行运动负荷超声心动图检查的主要目的是评估运动期间左心室流出道梗阻、二尖瓣反流、左心室运动不协调及舒张功能。当对HCM患者进行静息超声心动图检查时，对于劳力性症状所能给出的解释存在局限性。相比之下，运动负荷超声心动图可使静息时隐匿的表现显现出来，这可能有助于阐明症状的病因。在本文中，我们重点关注运动负荷超声心动图在HCM中的应用价值。
