Insights
The hemoglobin to creatinine ratio can predict contrast-induced nephropathy (CIN) in patients undergoing percutaneous coronary intervention (PCI). A lower ratio indicates a higher risk of developing CIN after the procedure.
Area of Science:
- Nephrology
- Cardiology
- Biomarkers
Background:
- Contrast-induced nephropathy (CIN) is a significant risk following percutaneous coronary intervention (PCI).
- Predictive markers for CIN are crucial for patient management and risk stratification.
Purpose of the Study:
- To evaluate the predictive value of the hemoglobin to creatinine ratio for CIN development in patients undergoing PCI.
- To identify key predictors of CIN in this patient population.
Main Methods:
- Prospective evaluation of 500 patients undergoing PCI.
- Calculation of baseline hemoglobin to creatinine ratio and glomerular filtration rate (GFR).
- Definition of CIN based on serum creatinine increase 48-72 hours post-contrast.
Main Results:
- CIN developed in 13.8% of patients.
- Hemoglobin to creatinine ratio, ejection fraction (EF), and contrast amount were significant predictors of CIN.
- Receiver operating characteristic (ROC) analysis showed good predictive performance for these markers (AUCs ranging from 0.694 to 0.731).
Conclusions:
- The hemoglobin to creatinine ratio is an independent predictor of CIN in patients undergoing PCI.
- EF and contrast amount also independently predict CIN development.
- These findings highlight the utility of the hemoglobin to creatinine ratio as a simple predictive tool for CIN.
Objectives:
Hemoglobin and creatinine levels are important factors for contrast induced nephropathy (CIN) development. Our aim in this study is to investigate the predictive value of hemoglobin to creatinine ratio for CIN development in patients with percutaneous coronary intervention (PCI).
Methods:
A total of 500 patients who underwent PCI in our clinic were evaluated prospectively in terms of CIN. Hemoglobin to creatinine ratio is calculated as baseline hemoglobin/baseline serum creatinine value. glomerular filtration rate (GFR) was calculated with Cockcroft-Gault formula. The definition of CIN includes absolute (≥0.5 mg/dL) or relative increase (≥25%) in serum creatinine at 48-72 h after exposure to a contrast agent compared to baseline serum creatinine values.
Results:
CIN was detected in 13.8% (69 patients) of 500 patients. In multivariate lineer regression analysis, hemoglobin to creatinine ratio (beta: -0.227, p=0.03) and ejection fraction (EF) (beta: -0.161, p<0.001), contrast amount used (beta: 0.231, p<0.001) were found to be significant predictors for the development of CIN. In receiver operating characteristics (ROC) analysis; AUC=0.730 (0.66-0.79) for hemoglobin to creatinine ratio, p<0.001, AUC=0.694 (0.62-0.76) for EF, p<0.001 and AUC=0.731 (0.67-0.78) for contrast amount used p<0.001.
Conclusions:
Hemoglobin to creatinine ratio, EF and contrast amount used were independent predictors for CIN development in patients with PCI (NCT04703049).
