The Society of Cardiovascular Angiography and Interventions (SCAI) reported a classification for cardiogenic shock. The authors are from multiple institutions in the United States, Canada and Germany.
Patient selection: cardiogenic shock
NOTE: This is similar to the hemodynamic profile for heart failure
Parameters:
(1) volume status (wet or dry)
(2) peripheral perfusion (cold or warm)
Volume Status
Peripheral Perfusion
Designation
dry
warm
vasodilatory shock (not cardiogenic shock)
dry
cold
mixed cardiogenic shock
wet
warm
euvolemic cardiogenic shock
wet
cold
classic cardiogenic shock
The cardiac index is increased for vasodilatory shock but low in cardiogenic shock.
Parameter
Dry
Wet
pulmonary capillary wedge pressure (PCWP)
low or normal
elevated
Parameter
Warm
Cold
systemic vascular resistance
low to normal
