Treatment of NSTEMI with Low Risk of Ischemic Events, Normal Cardiac Biomarkers, and No High-Risk Features
Clinical scenario
This protocol addresses Non-ST-elevation myocardial infarction (NSTEMI) presenting with a low risk of ischemic events, normal cardiac biomarkers, absence of high-risk features, and no dynamic ST-segment changes. Identifying which patients in this group may benefit from revascularization — and reducing the risk of major adverse cardiovascular events — are the central clinical priorities.
Defining patient profile
Patients in this subset share four key characteristics: low ischemic risk on initial assessment, normal cardiac biomarkers, no high-risk features on presentation, and a stable electrocardiogram without dynamic ST-segment changes. In this population, either a routine invasive or a selective invasive approach is recommended to guide further management.
Management approach
The recommended strategy for this patient group involves an invasive coronary angiography approach carried out prior to hospital discharge to determine the need for revascularization.
The complete structured regimen — including full procedural criteria, patient selection details, and the management algorithm — is available in the full protocol.

- In patients with NSTE-ACS who are at low risk of ischemic events, either a routine invasive or selective invasive approach is recommended to help identify those who may require revascularization and to reduce MACE.
- In patients with NSTE-ACS who are not at high risk and are intended for an invasive strategy, it is reasonable to perform angiography before hospital discharge to reduce MACE.
- Patients with higher risk findings on noninvasive testing or who have recurrent ischemic symptoms should be referred for invasive coronary angiography prior to hospital discharge in the absence of contraindication.
