Abstract:
BACKGROUND: Coronary stenting is one of the most effective methods of percutaneous coronary interventions (PCI) in the treatment of intimal dissection and prevention of restenosis after balloon angioplasty. However, coronary stent restenosis still remains a major clinical limitation. METHODS: Three hundreds seventy three patients who underwent coronary stent implantations and follow-up coronary aniograms at Chonnam National University Hospital between June 1996 and December 1999, were divided into two groups: 123 patients with restenosis (Group A: 98 male, 25 female, 58.5+/-9.4 year-old) and 240 patients without restenosis (Group B: 193 male, 47 female). RESULTS: The prevalence of clinical diagnosis and risk factors for the atherosclerosis were not different between two groups. The indications for stenting and stent types, reference vessel diameter and minimal luminal diameter before stenting were not different. However, stent length was 23.4+/-7.57 mm in Group A and 20.8+/-6.58 mm in Group B, which were longer in Group A than in Group B (p=001). By multiple logistic regression analysis for the independent predictive factors for stent restenosis, the long stent more than 25mm in length was the only significant predictive factor after correction according to age, sex, risk factor, lipid profiles (OR=2.590, 95% C.I.=1.40-4.78). CONCLUSION: The long coronary stent more than 25 mm in length is a predictive factor of restenosis after coronary stenting.
