"Coronary Computed Tomographic Angiography Its Role in Emergency Department Triage"
"Conclusions
Coronary CTA is now an established, noninvasive technique that can rapidly exclude obstructive CAD and identify patients who can be safely discharged from the ED. Although CTA appears to lower ED costs and may lead to intensification in preventive therapies, concern remains about the potential for this test to increase invasive angiography and coronary revascularizations. Ultimately, appropriate patient selection will remain essential for ensuring optimal test use and patient management."
