SCAI Clinical Expert Consensus Statement on Cardiogenic Shock
Vikas Aggarwal, MBBS, MPH , FACC
The following are key points to remember from this summary of the Society for Cardiovascular Angiography and Interventions (SCAI) Clinical Expert Consensus Statement on the Classification of Cardiogenic Shock (CS). The document is endorsed by the American College of Cardiology, American Heart Association, Society of Critical Care Medicine, and Society of Thoracic Surgeons:
A system describing stages of CS from “A to E” is proposed. The purpose of this proposed classification of CS is to enable clear communication regarding patient status and to allow clinical trials to appropriately differentiate CS patient subsets.
Additionally, the(A)modifier for cardiac arrest is applied to describe those who suffer a cardiac arrest irrespective of duration (treated with chest compressions or direct current cardioversion). Accordingly, a patient may be in stage BA shock, indicating stage B with a cardiac arrest complicating the clinical picture (e.g., a patient who presents with ventricular fibrillation in the setting of acute MI and rapidly stabilizes with prompt defibrillation).
