Echocardiography - Summary of recommendations and evidence
Transthoracic echocardiography must be performed for a differential diagnosis when there is clinical suspicion of aortic disease, pericardial disease, pulmonary embolism, or heart valve disease.	I	C
Emergency echocardiography should be performed when there are complications resulting from NSTE-ACS, such as interventricular communication and mitral regurgitation.	I	C
Stress echocardiography can be used for functional stratification in patients without recurrent chest pain or ECG evidence of ischemia and/or troponin elevation.	I	B
In patients with chest pain, resting echocardiography can identify changes compatible with ischemic etiology.	IIa	C
