Results of logistic regression, angiography within 6 h of cardiac arrest vs. no early angiography. Increasing time to ROSC, a higher serum creatinine on admission and treatment with IABP were independently associated with a higher risk of AKI whereas an initial shockable rhythm was associated with less AKI. Normal lactate clearance was defined as lactate < 2.0 mmol/L alt 12 h or a decrease in lactate > 50% within 12 h of cardiac arrest
