Flash Glucose Monitoring for Predicting Cardiogenic Shock Occurrence in Critically Ill Patients: A Retrospective...

Area of Science:

• Critical care medicine
• Endocrinology
• Cardiology

Background:

• Continuous and flash glucose monitoring (CGM/FGM) offer real-time glucose data, crucial for critically ill patients.
• Altered blood glucose, especially hypoglycemia, is linked to adverse outcomes in critical care.
• Hyperglycemia is common, but hypoglycemia poses a significant risk of fatal outcomes.

Purpose of the Study:

• To investigate the association between flash glucose monitoring (FGM) variables and cardiogenic shock in critically ill Coronary Care Unit (CCU) patients.
• To compare hypoglycemia detection rates between FGM and standard glucose monitoring in CCU patients.
• To determine if FGM-detected hypoglycemia is an independent predictor of cardiogenic shock.

Main Methods:

• Twenty-eight CCU patients were monitored using a Libre FreeStyle system.
• Data analyzed included demographics, lab results, ejection fraction, standard glucose monitoring, APACHE IV scores, and shock occurrence.
• Statistical analyses included chi-squared, Mann-Whitney U tests, and logistic regression.

Main Results:

• 13 patients (46.43%) developed cardiogenic shock.
• FGM detected hypoglycemia in 64.29% of patients, versus 21.43% with standard methods.
• FGM-detected hypoglycemia and time below range were significantly higher in patients who developed shock (p=0.0129, p=0.0093), and it was an independent shock predictor (p=0.0390).

Conclusions:

• Flash glucose monitoring identifies more hypoglycemic events than standard methods in CCU settings.
• Frequent FGM-detected hypoglycemia is associated with cardiogenic shock, irrespective of diabetes history.
• Further research is warranted due to the limited sample size, but FGM shows promise in predicting adverse events.
