Risk stratification of patients presenting with NSTEACS

Very high riskHigh riskLow risk
Cardiogenic shockEstablished NSTEACS diagnosisNone of the previous characteristics
Haemodynamic instabilityDynamic new contiguous ST/T-segment changes
Acute heart failure related to NSTEACSResuscitated cardiac arrest without ST-segment elevation or cardiogenic shock
Mechanical complication of MIGRACE risk score>140
Life-threatening arrhythmias
Recurrent/refractory chest pain
ST-segment depression>1 mm/6 leads plus ST-segment elevation aVr and/or V1
