Stress hyperglycemia ratio emerges as a novel independent predictor of acute kidney injury among critically ill patients with acute heart failure: A retrospective analysis of the MIMIC-IV database

Key Points

• The study aims to explore the relationship between the stress hyperglycemia ratio and acute kidney injury in critically ill patients with acute heart failure.
• Conducted a retrospective analysis using the MIMIC-IV database
• Analyzed the association between stress hyperglycemia ratio and acute kidney injury
• Examined mortality risk related to different levels of the stress hyperglycemia ratio
• Found a linear association between the stress hyperglycemia ratio and acute kidney injury
• Identified a critical threshold of 0.841 for in-hospital mortality risk
• Demonstrated a U-shaped relationship with 28-day in-hospital mortality
