Society of Cardiovascular Angiography and Interventions classification of cardiogenic shock profiles.8
| STAGE | PATIENT DESCRIPTION | |
|---|---|---|
| A | At risk | Large acute myocardial infarctions (MIs); prior MI or acute/chronic heart failure symptoms |
| B | Pre-shock/compensated shock | Clinical evidence of relative hypotension or tachycardia without hypoperfusion |
| C | Classic cardiogenic shock |
|
| D | Deteriorating | Patient's symptoms have escalated and fail to respond to initial interventions found in stage C |
| E | Extremis | Circulatory collapse requiring multiple interventions and support |
[i] MI: myocardial infarction
