Summary

? A number of imaging modalities may be used in evaluating stable patients with chest pain suggestive of ACS and who are not selected for urgent cardiac catheterization.

? Although cardiac catheterization is the mainstay for evaluation of patients in whom a diagnosis of NSTEMI( Non ST elevation Myocardial Infarction)
is made,

in the clinically stable patient with angina or UA ( unstable Angina), alternative noninvasive imaging modalities may be appropriate.

? Noninvasive imaging in this setting includes MPI, coronary CT angiography, cardiac MRI, and stress echocardiography. These tests may be performed as an intermediate step and may improve confidence regarding the safety of discharge from the emergency department.
