| pubmed-article:14571485 | pubmed:abstractText | To determine the incidence and predictors of total occlusion in-stent restenosis, we reviewed three randomized stent vs. stent trials and one stent registry, which provided 955 coronary artery lesions with 6-month angiographic follow-up. Fifteen (1.6%) of the 955 stented lesions were totally occluded at 6-month follow-up. Most patients with total occlusion presented with recurrent angina at the time of repeat angiography (60.0%) while no patient presented with an acute ST segment elevation myocardial infarction. The univariate predictors of total occlusion following elective coronary stenting included stenting for restenosis after a previous percutaneous intervention (P = 0.001), longer stent length (P < 0.001), longer lesion length (P < 0.001), smaller reference vessel diameter (P = 0.022), smaller preprocedure minimum lumen diameter (MLD; P = 0.004), and smaller postprocedure MLD (P = 0.036). Stepwise multiple logistic regression analysis demonstrated that stenting for restenotic lesions (P = 0.004), longer stent length (P < 0.001), and smaller preprocedure MLD (P = 0.012) were independent predictors of total occlusion following coronary stenting. | lld:pubmed |
