Phenotypes of cardiogenic shock after out-of-hospital cardiac arrest: the SCAI-V classification.
EuroIntervention : journal of EuroPCR in collaboration with the Working Group on Interventional Cardiology of the European Society of Cardiology·September 21, 2026·PMID 42765398
Why it mattersCurrent cardiogenic shock classifications often misclassify post-arrest patients because hypoperfusion mechanisms differ from non-arrested shock. The SCAI-V classification integrates lactate, a readily available marker of systemic ischaemia, to better phenotype these patients and potentially guide early invasive therapies.
