CS2 Score (Cardiogenic Shock Survival) Calculator

Explanation and clinical context The CardShock score was developed from a multicenter cohort to predict short-term mortality in patients with cardiogenic shock of various etiologies and uses seven admission variables (age, confusion, previous MI/CABG, ACS as cause, LVEF, lactate and eGFR). The IABP-SHOCK II score was derived from the IABP-SHOCK II trial in AMI-related cardiogenic shock; it uses variables available at admission (age, prior stroke, admission glucose, creatinine, lactate and TIMI flow after PCI). Both scores have been externally validated in multiple cohorts; each has specific scope and limitations (IABP-SHOCK II is AMI-specific and includes a post-PCI angiographic item).

Use these scores to augment— not replace—clinical decision making. See references below for the original derivation and major validations. References Harjola V-P et al., CardShock study — Clinical picture and risk prediction of short-term mortality in cardiogenic shock (CardShock score).
