IABP SHOCK II Score for a Patient with Cardiogenic Shock After Acute Myocardial Infarction

Description

The IABP SHOCK II (Intraaortic Balloon Pump in Cardiogenic Shock) score can be used to evaluate a patient with acute myocardial infarction (AMI). This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple institutions in Germany and Finland.

Patient selection: cardiogenic shock after acute myocardial infarction

Outcome: 30-day mortality

Parameters:

(1) age in years

(2) history of stroke

(3) glucose in mmol/L

(4) serum creatinine in µmol/L

(5) arterial blood lactate concentration in mmol.L

(6) TIMI flow grade after PCI (from 0 to 3)

Parameter	Finding	Points
age in years	<= 73 yeares	0
	> 73 years	1
history of stroke	no	0
	yes	2
glucose	<= 10 mmol/L (191 mg/dL)	0
	> 10 mmol/L	1
creatinine	<= 132.6 µmol/L (1.5 mg/dL)	0
	> 132.6 µmol/L	1
lactate	<= 5 mmol/L	0
	> 5 mmol/L	2
TIMI flow grade	0 to 2	2
	3	0

total score =

= SUM(points from all 6 parameters)

Interpretation:

• minimum score: 0

• maximum score: 9

• The higher the score the greater the mortality.

Total Score	Risk Category	30-Day Mortality
0 to 2	low	28%
3 or 4	intermediate	43%
5 to 9	high	77%
