Does Lipoprotein (a) Level Have a Predictive Value in Restenosis after Coronary Stenting?

Objectives: lipid disorders, lipoproteins, diabetes mellitus, and hypertension are the known risk factors for coronary artery dis- eases; however, their role is unknown in restenosis after coronary stenting. this study aimed to review the role of these factors, par- ticularly 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.
