Prognostic value of glycaemic variability for mortality in cardiogenic shock patients: a retrospective cohort study

GV is a significant predictor of 30-day, 90-day, and 360-day all-cause mortality after ICU admission in non-diabetic CS patients. GV may serve as a valuable marker for risk stratification and guiding subsequent interventions in CS non-diabetic patients, which emphasized the importance of stable control of blood glucose.
