Insights
The systemic immune-inflammation index (SII) can predict contrast-induced nephropathy (CIN) risk in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). Higher SII levels significantly correlate with increased CIN development.
Area of Science:
- Cardiology
- Nephrology
- Inflammation Biomarkers
Background:
- Contrast-induced nephropathy (CIN) is a significant complication in patients with ST-segment elevation myocardial infarction (STEMI).
- Predictive markers for CIN risk stratification are crucial for optimizing patient management after primary percutaneous coronary intervention (pPCI).
Purpose of the Study:
- To evaluate the predictive value of the admission systemic immune-inflammation index (SII) for CIN risk.
- To assess the relationship between SII, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) with CIN development in STEMI patients.
Main Methods:
- A cohort of 1621 STEMI patients treated with pPCI was analyzed.
- Admission SII, NLR, and PLR levels were calculated.
- The association between inflammatory markers and CIN development within 72 hours was assessed using multivariable logistic regression.
Main Results:
- 343 patients (21.1%) developed CIN.
- CIN frequency increased significantly across SII quartiles (11.1% to 35%, P < .01).
- Higher SII quartiles were independent predictors of CIN (3rd vs 1st: OR 2.906, 4th vs 1st: OR 4.168).
Conclusions:
- Admission SII is a promising inflammatory biomarker for predicting CIN risk in STEMI patients undergoing pPCI.
- SII offers a valuable tool for early identification of high-risk individuals requiring closer monitoring or preventive strategies.
Abstract:
We evaluated the predictive value of admission systemic immune-inflammation index (SII) for the risk of contrast-induced nephropathy (CIN) in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI). The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and SII (platelet × NLR) levels were calculated in 1621 consecutive patients with STEMI. The relationship of these parameters with CIN development within 72 hours of pPCI was analyzed. Of the study population, 343 (21.1%) cases developed CIN. The frequency of CIN was 11.1% in the first SII quartile, 11.6% in the second SII quartile, 26.8% in the third SII quartile, and 35% in the fourth SII quartile, which differed significantly between groups (P < .01). Age, baseline glomerular filtration rate, contrast media volume, hypertension, C-reactive protein levels, and the quartiles of SII were independent predictors of CIN. Patients in the third SII quartile versus first SII quartile (OR: 2.906, 95% CI, 1.903-4.437; P < .001), and fourth SII quartile versus first SII quartile (OR: 4.168, 95% CI, 2.754-6.313; P < .001) had a significantly higher risk for CIN in the multivariable model. The SII may be a promising inflammatory parameter to predict CIN after pPCI.
