Transthoracic echocardiography (TTE) can be helpful for diagnosis the causes of acute chest<unk>  such as acute aortic dissection, pericardial effusion, stress cardiomyopathy, and hypertrophic cardiomyopathy. In addition, TTE does provide information for patients with acute chest<unk>  and suspected ACS about left and right ventricular function and regional wall motion abnormalities. Stress echocardiography can be used to define ischemia severity and for risk  stratification purposes when ≥2  contiguous  segments of wall motion abnormalities in coronary  territories are visualized.
