The Relationship Between Glycated Hemoglobin Levels and In-Stent Restenosis After Percutaneous Coronary Intervention in Patients with Coronary Artery Disease
To examine the association between glycated hemoglobin (HbA1c) levels and the risk of in-stent restenosis (ISR) in coronary artery disease (CAD) patients following percutaneous coronary intervention (PCI), highlighting its significance in improving patient outcomes.
Key Findings:
20.72% of participants were diagnosed with ISR, totaling 1305 individuals.
Higher HbA1c levels were significantly associated with increased ISR risk (OR: 1.18, 95% CI 1.09–1.27, p <0.0001).
Patients with HbA1c ≥6.5% had a substantially higher risk of ISR (OR: 1.70, 95% CI 1.26–2.29, p =0.0005).
A non-linear association was found, with a threshold effect at an HbA1c level of 7.8%.
Interpretation:
The study indicates that higher HbA1c levels are linked to an increased risk of ISR in CAD patients after PCI, suggesting the importance of glycemic control in this population for better clinical outcomes.
Limitations:
Retrospective design may introduce selection bias.
Data limited to a single institution may affect generalizability and external validity.
Potential confounding factors not fully accounted for.
Conclusion:
There is a non-linear relationship between increased HbA1c levels and the risk of ISR in CAD patients post-PCI, highlighting the need for careful glycemic management to improve patient outcomes.
