Risk factors for coronary in-stent restenosis in Moroccan patients: a retrospective case-control study

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Biology

Background:

• In-stent restenosis (ISR) poses a significant clinical challenge in interventional cardiology.
• Despite advancements, identifying specific risk factors for ISR remains critical for patient outcomes.

Purpose of the Study:

• To investigate the risk factors associated with coronary in-stent restenosis.
• To evaluate the role of diabetes mellitus and lipid profiles in the development of ISR.

Main Methods:

• Retrospective case-control study involving 68 patients (restenosis vs. no-restenosis groups).
• Analysis of clinical data, including diabetes status, lipid profiles, medication duration, and stent characteristics.
• Univariate logistic regression to identify significant predictors of restenosis.

Main Results:

• Diabetes mellitus was a powerful predictor of restenosis (RR=4.15).
• Restenosis patients had significantly higher LDL cholesterol and lower HDL levels.
• Medication intake duration (OR=1.30) and LDL levels (OR=26.7) were significant factors.

Conclusions:

• Diabetes mellitus is a critical determinant of coronary in-stent restenosis.
• Synergistic effects of diabetes and lipid abnormalities contribute to ISR.
• Targeted preventive strategies, including glycemic and lipid management, are essential for diabetic patients undergoing PCI.
