ACR Appropriateness Criteria® chest pain, suggestive of acute coronary syndrome.


Summary

* A number of imaging modalities may be utilized in evaluating stable patients with chest pain suggestive of acute coronary syndrome and who are not selected for urgent cardiac catheterization.
* Although cardiac catheterization is the mainstay for evaluation of patients in whom acute coronary syndrome is being considered, in the clinically stable patient with UA/NSTEMI, alternative noninvasive imaging modalities may be appropriate.
* Noninvasive imaging in this setting includes myocardial perfusion scanning, coronary CT angiography, and echocardiography. These tests may be performed as an intermediate step and may improve confidence regarding the safety of discharge from the emergency department.
