Serum creatinine role in predicting outcome after cardiac surgery beyond acute kidney injury

Area of Science:

• Nephrology
• Cardiology
• Perioperative Medicine

Background:

• Serum creatinine is the primary marker for perioperative renal function and adverse outcomes in cardiac surgery.
• Current biomarkers lack the feasibility and cost-effectiveness of serum creatinine.
• Elevated serum creatinine is a significant preoperative risk factor for postoperative renal injury.

Purpose of the Study:

• To emphasize the continued importance of serum creatinine in clinical practice.
• To highlight its role in risk prediction models for cardiac surgery patients.
• To discuss future directions in acute kidney injury diagnosis.

Main Methods:

• Review of existing literature on renal function biomarkers in cardiac surgery.
• Analysis of the role of serum creatinine in risk assessment and outcome prediction.
• Exploration of emerging diagnostic tools for acute kidney injury.

Main Results:

• Serum creatinine is indispensable for assessing perioperative renal function and predicting adverse outcomes.
• No current biomarker has replaced serum creatinine due to its practicality and affordability.
• Risk factor reduction strategies have amplified the significance of creatinine in outcome prediction.

Conclusions:

• Serum creatinine remains the cornerstone for evaluating renal function and predicting outcomes in cardiac surgery.
• Future advancements in acute kidney injury diagnosis will likely integrate serum creatinine with novel biomarkers.
