Mortality from cardiogenic shock remains high and early recognition and risk stratification are mandatory for optimal patient allocation and to guide treatment strategy.
The Intra-Aortic Balloon Counterpulsation in Acute Myocardial Infarction Complicated by Cardiogenic Shock (IABP-SHOCK II) risk score has shown good results in predicting short-term mortality in cardiogenic shock.
The IABP-SHOCK II risk score is a simple tool that can be rapidly calculated in the catheterization laboratory setting and applied in clinical routine. It might therefore serve for identifying patients for future clinical trials and, more importantly, it might help stratify patients according to their risk for short-term mortality and thus facilitate clinical decision making. The scoring system attributed one or two points per variable.
| SCORE | |
| Variable | Points |
| Age > 73 years | 1 |
| History of stroke | 2 |
| Glucose > 10.6 mmol/l (191 mg/dl) | 1 |
| Creatinine > 132.6 mmol/l (1.5 mg/dl) | 1 |
| Arterial lactate > 5 mmol/l | 2 |
| TIMI flow grade < 3 after PCI | 2 |
| Maximum | 9 |
Interpretation
| RISK CATEGORIES | |
| Category | Points |
| Low | 0-2 |
| Intermediate | 3-4 |
| High | 5-9 |
Cardiogenic Shock Complicating Acute Myocardial Infarction
The IABP-SHOCK II risk score can be easily calculated in daily clinical practice and strongly correlated with mortality in patients with infarct-related CS. It may help stratify patient risk for short-term mortality and might, thus, facilitate clinical decision making.
