High risk features and markers of patients with non-ST elevation ACS

CABG, coronary artery bypass graft; CRP, C reactive protein, IL, interleukin; LV, left ventricular; MI, myocardial infarction; NT pro BNP, N terminal pro brain type natriuretic peptide.
▸ High risk features in the early triage of patients
        Continued or recurrent ischaemia at rest
        Ischaemia complicated by cardiac failure, arrhythmia or mechanical complications
        Ischaemia with ST segment depression and/or troponin elevation
        Dynamic ST changes
▸ Markers of pre-existing longer term risk
        Prior MI, CABG, diabetes, congestive heart failure, or hypertension
        Biological markers of renal dysfunction (raised creatinine or reduced creatinine clearance)
        Elevated inflammatory markers (high sensitivity CRP, IL-6, CD40L)
▸ LV dysfunction
        Invasive or non-invasive markers of LV dysfunction or mechanical complication
        Biological markers of LV dysfunction (NT pro BNP)
        Extent of coronary artery disease on angiography
