SCAI Shock Stages A Through E

SCAI Shock Stages A Through E The Society for Cardiovascular Angiography and Intervention (SCAI) has classified cardiogenic shock into stages from A through E. This was developed by a multidisciplinary team from cardiology (interventional, advanced heart failure and noninvasive), emergency medicine, critical care and cardiac nursing. Stage A: “At risk” for cardiogenic shock – large myocardial infarction or heart failure, but not yet in shock, with normal mentation and systolic blood pressure of 100 mm Hg or more. Stage B: “Beginning” shock – hypotension or tachycardia without features of hypoperfusion (normal mentation). Systolic BP < 90, mean arterial pressure (MAP) <60 or 30 mm Hg fall in BP. Stage C: “Classic” cardiogenic shock – has hypotension with features of hypoperfusion, needing inotropes and mechanical circulatory support. Stage D: “Deteriorating” – needs multiple inotropes or mechanical circulatory support to maintain perfusion. Initial interventions have failed. Stage E: “Extremis” – in cardiac arrest with ongoing CPR or ECMO support, nearly pulseless, hypotension despite maximal support. This is a brief description of the stages. More detailed description is available in the SCAI statement (Free Full Text).
