摘要In the context of the People's Republic of China,coronary artery disease(CAD)presents a sig-nificant clinical challenge,with over 11.3 mil-lion patients diagnosed.Traditionally,the diagnos-is of CAD has predominantly relied on invasive coronary angiography.[1]However,recent advances in clinical research have revealed a notable trend:a substantial 82％of patients subjected to such invas-ive diagnostics do not necessitate interventional therapy.[2]In order to standardize the clinical dia-gnosis and treatment strategy of CAD myocardial ischemia,this revelation has led to a paradigm shift in the diagnostic and management approaches for myocardial ischemia associated with CAD.Current international guidelines have evolved to prioritize stress imaging tests as the primary diagnostic step for patients presenting with chronic chest pain or suspected CAD.Within this framework,stress echocardiography(SE)has gained recognition as a Class Ⅰ recommended diagnostic protocol,espe-cially for patients exhibiting symptoms of stable angina.
