Treatment of Unstable Angina with Very High-Risk Criteria in NSTE-ACS
When a working diagnosis of NSTE-ACS/unstable angina is accompanied by at least one very high-risk feature, the clinical situation demands an urgent, structured response. Identifying the qualifying criterion at presentation is the first step toward the appropriate management pathway.
Very High-Risk Criteria — any one qualifies
- Haemodynamic instability or cardiogenic shock
- Recurrent or refractory chest pain despite medical treatment
- In-hospital life-threatening arrhythmias
- Mechanical complications of myocardial infarction
- Acute heart failure presumed secondary to ongoing myocardial ischaemia
- Recurrent dynamic ST-segment or T wave changes on ECG
Management Overview
The central strategy in this setting is an immediate invasive approach — emergency coronary angiography as soon as possible, with intervention where indicated. From the time of diagnosis, this is accompanied by concurrent supportive measures and a regimen combining antiplatelet therapy and parenteral anticoagulation.
Full agent selection, sequencing, individualised criteria, and the complete regimen are available in the structured protocol below.

- An immediate invasive strategy is recommended in patients with a working diagnosis of NSTE-ACS and with at least one of the following very high-risk criteria:
- Haemodynamic instability or cardiogenic shock
- Recurrent or refractory chest pain despite medical treatment
- In-hospital life-threatening arrhythmias
- Mechanical complications of MI
- Acute heart failure presumed secondary to ongoing myocardial ischaemia
- Recurrent dynamic ST-segment or T wave changes, particularly intermittent ST-segment elevation.
- An immediate invasive strategy refers to emergency (i.e. as soon as possible) angiography and PCI if indicated.
- In all ACS patients, a P2Y12 receptor inhibitor is recommended in addition to aspirin, given as an initial oral LD followed by an MD for 12 months unless there is HBRc.
- Parenteral anticoagulation is recommended for all patients with ACS at the time of diagnosis.
