：Coronary heart disease (CHD) affects a wide population and has a high
mortality rate, which seriously threatens the life safety of patients.
Early diagnosis and effective treatment can significantly improve the
survival and prognosis of the CHD patients. At present, it is mainly
judged by detecting various myocardial biomarkers, myocardial movement
and coronary blood flow. Stress echocardiography (SE) is one of the
commonly used detection methods. It can not only judge the severity of
coronary stenosis, but also evaluate myocardial survival and distinguish
hibernating myocardium and stunned myocardium. In recent years, it has
also emerged in non-coronary heart disease such as artificial valve and
hypertrophic cardiomyopathy. This article briefly reviews the principle
and classification of SE, and it mainly discusses its important value in
the diagnosis and prognosis of CHD.
