Assessment by stress echocardiogram - Summary of recommendations and evidence
Use in patients with unstable angina or clinically controlled low-risk NSTE-ACS* before deciding on an invasive strategy.	IIa	A
Use to assess the functional significance of moderate coronary obstruction on angiography, as long as a result interferes with management.	IIa	C
Use for risk stratification after uncomplicated myocardial infarction.	IIa	A
Use to investigate suspected microvascular disease to determine whether segmental changes occur in conjunction with angina and ECG changes.	IIa	C
Use strain and strain rate parameters derived from speckle tracking as an adjunct tool to the wall motion score index for diagnosis and/or prognosis of acute coronary disease.	IIa	B
Use in high-risk unstable angina or acute myocardial infarction.	III	C

^*Without recurrent angina, signs of HF, changes in initial/serial ECG and with normal troponin; typical anginal pain with abnormal ECG or functional test with normal cardiac catheterization.
