Insights
Red blood cell distribution width (RDW) and stent length are significant predictors of in-stent restenosis (ISR) after drug-eluting stent implantation. Their combined use improves risk stratification for patients with acute myocardial infarction.
Area of Science:
- Cardiology
- Interventional Cardiology
- Biomarkers
Background:
- In-stent restenosis (ISR) following drug-eluting stent (DES) implantation remains a clinical challenge.
- Predictive markers for ISR are limited, necessitating accessible clinical indicators.
Purpose of the Study:
- To evaluate the predictive value of red blood cell distribution width (RDW) and stent length for ISR in patients with acute myocardial infarction (AMI).
Main Methods:
- Retrospective analysis of 170 patients undergoing stent implantation for AMI.
- Comparison of clinical and laboratory parameters between restenosis and non-restenosis groups at 12-month follow-up.
- Multivariate logistic regression and receiver operating characteristic (ROC) analyses.
Main Results:
- RDW and stent length were significantly higher in the restenosis group.
- Both RDW and stent length were identified as independent predictors of ISR.
- Combined analysis of RDW and stent length showed enhanced predictive performance for ISR.
Conclusions:
- RDW and stent length are significant predictors of ISR after DES implantation.
- These parameters can serve as practical indicators for risk stratification in patients undergoing stent procedures.
Abstract:
This study investigated the predictive value of red blood cell distribution width (RDW) stent length for in-stent restenosis (ISR) drug-eluting stent implantation in patients with acute myocardial infarction. Reliable predictors of restenosis remain limited, highlighting the need for accessible clinical markers. A total of 170 patients who underwent stent implantation were included and classified into restenosis and nonrestenosis groups based on follow-up coronary angiography at 12 months. Clinical characteristics and laboratory parameters were compared between groups. Multivariate logistic regression and receiver operating characteristic analyses were performed to evaluate associations and predictive performance. The results showed that RDW and stent length were significantly higher in patients with restenosis and were independent predictors of restenosis risk. The combined use of these variables demonstrated improved predictive performance compared to using the variables individually. In conclusion, RDW and stent length are significant predictors of ISR and may serve as practical indicators for risk stratification in patients undergoing stent implantation.
