What are the recommended uses of noninvasive testing for ischemia before discharge?
Noninvasive testing for ischemia should be performed before discharge to assess the presence and extent of inducible ischemia in patients with STEMI who have not had coronary angiography and do not have high- risk clinical features for which coronary angiography would be warranted. Noninvasive testing for ischemia might also be considered before discharge to evaluate the functional significance of a noninfarct artery stenosis previously identified at angiography, and to guide the postdischarge exercise prescription.
