Insights
Neutrophil-to-lymphocyte ratio (NLR), mean platelet volume-to-lymphocyte ratio (MPVLR), and platelet-to-lymphocyte ratio (PLR) can predict contrast-induced nephropathy (CIN) after procedures. MPVLR was the strongest predictor of CIN risk in acute coronary syndrome patients.
Area of Science:
- Cardiology
- Nephrology
- Hematology
Background:
- Contrast-induced nephropathy (CIN) is a significant complication following cardiovascular interventions.
- Inflammatory markers like neutrophil-to-lymphocyte ratio (NLR), mean platelet volume-to-lymphocyte ratio (MPVLR), and platelet-to-lymphocyte ratio (PLR) may indicate CIN risk.
Purpose of the Study:
- To investigate the association between NLR, MPVLR, PLR, and the development of CIN in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI).
Main Methods:
- Retrospective analysis of 564 ACS patients who underwent coronary angiography (CA).
- Comparison of NLR, MPVLR, and PLR levels between patients who developed CIN (n=62) and those who did not (n=502).
Main Results:
- Patients who developed CIN exhibited significantly higher MPVLR, NLR, and PLR.
- MPVLR emerged as an independent predictor of CIN (P ≤ .001).
- MPVLR demonstrated the strongest predictive capability for CIN among the studied indices.
Conclusions:
- NLR, MPVLR, and PLR are accessible, cost-effective biomarkers for predicting CIN risk.
- MPVLR is a particularly strong and independent predictor of contrast-induced nephropathy in ACS patients post-PCI.
Abstract:
Contrast-induced nephropathy (CIN) is one of the most important complications after invasive cardiovascular procedures. The neutrophil-to-lymphocyte ratio (NLR), mean platelet volume-to-lymphocyte ratio (MPVLR), and platelet-to-lymphocyte ratio (PLR) may be markers of the risk of CIN. We aimed to investigate the association of these indices with the development of CIN in patients with ST-elevation myocardial infarction and non-ST-elevation-acute coronary syndrome who underwent percutaneous coronary intervention. We retrospectively collected the data of patients with ACS after coronary angiography (CA); 564 patients were included (mean age, 62.3 ± 13.0 years; 41.1% female). We compared 62 (10.9%) patients who developed CIN and 502 patients who did not, after CA in terms of NLR, PLR, and MPVLR. Patients who developed CIN had significantly higher MPVLR, NLR, and PLR; the MPVLR (P ≤ .001) was an independent predictor of CIN. NLR, MPVLR, and PLR are simple, cheap, and easily accessible tests that can predict CIN; the MPVLR was the strongest of these predictors.
