Abstract


Objectives: Lipid disorders, lipoproteins, diabetes mellitus, and hypertension are the known risk factors for coronary artery diseases; however, their role is unknown in restenosis after coronary stenting. This study aimed to review the role of these factors, particularly lipoprotein (a) or Lp (a), as a predictive factor for restenosis after coronary stenting with Bare Metal Stent.

Methods: In this study, coronary artery stenting was performed on 170 patients. Follow-up was done using coronary angiography in 128 patients, 6 months after conducting angioplasty. Clinical and biochemical characteristics of the patients were collected as prospective method and were compared between the patients with and without restenosis.

Results: Restenosis was seen in 46 patients (35.9%). Fasting blood glucose level (FBG) in patients with restenosis was significantly higher than patients without restenosis (102.3 ± 39 mg/dl vs. 84.5 ± 28.9 [OR: 1.02, 95% CI: 1.00-1.04]). Lp (a) levels (OR: 0.54, 95% CI: 0.26-1.10) and other biochemical markers and clinical variables had no correlation with restenosis.

Conclusions: Lipoproteins and lipids may not be the underlying cause of restenosis but accurate control of diabetes may improve prognosis after elective coronary stenting.

Keywords: Stent, Restenosis, Lipoprotein (a), Lipid, Diabetes.
