Contemporary Management of Cariogenic Shock
Pragmatic and Clinical Trial Definitions of Cardiogenic Shock
| Clinical Definition | SHOCK Trial | IABP-SHOCK II | ESC HF Guidelines |
|---|---|---|---|
| Cardiac disorder that results in both clinical and biochemical evidence of tissue hypoperfusion | Clinical criteria:
SBP <90 mmHg for ≥30 min OR Support to maintain SBP ≥90 mmHg AND End-organ hypoperfusion (urine output <30 mL/h or cool extremities) Hemodynamic criteria: CI of ≤2.2 L·min−1·m−2 AND PCWP ≥15 mmHg |
Clinical criteria:
SBP <90 mmHg for ≥30 min OR Catecholamines to maintain SBP >90 mmHg AND Clinical pulmonary congestion AND Impaired end-organ perfusion (altered mental status, cold/clammy skin and extremities, urine output <30 mL/h, or lactate >2.0 mmol/L) |
SBP <90 mmHg with adequate volume and clinical or laboratory signs of hypoperfusion
Clinical hypoperfusion: Cold extremities, oliguria, mental confusion, dizziness, narrow pulse pressure Laboratory hypoperfusion: Metabolic acidosis, elevated serum lactate, elevated serum creatinine |
| CI indicates cardiac index; CS, cardiogenic shock; ESC, European Society of Cardiology; HF, heart failure; IABP-SHOCK II, Intraaortic Balloon Pump in Cardiogenic Shock II; LV, left ventricular; MI, myocardial infarction; PCWP, pulmonary capillary wedge pressure; SBP, systolic blood pressure; and SHOCK, Should We Emergently Revascularize Occluded Coronaries for Cariogenic Shock | |||
Potential Hemodynamic Presentations of Cardiogenic Shock
| Volume Status | |||
| Peripheral Circulation | Cold | Classic Cardiogenic Shock or Mixed Shock (↓Cl; ↑SVRI; ↑PCWP) | Euvolemic Cardiogenic Shock (↓Cl; ↑SVRI;↔PCWP) |
| Peripheral Circulation | Warm | Vasodilatory Cardiogenic Shock or Mixed Shock (↓Cl; ↓/↔SVRI;↑PCWP) | Vasodilatory Shock (Not Cardiogenic Shock) (↑Cl; ↓SVRI; ↓PCWP) |
| CI indicates cardiac index; PCWP, pulmonary capillary wedge pressure; and SVRI, systemic vascular resistance index. | |||
