Abstract

Variable rates of restenosis after carotid artery stenting (CAS) have been reported, and few predictors have been suggested. Because CAS is being performed with increasing frequency, more data are needed to evaluate the rate and predictors of restenosis and possibly identify new risk factors for restenosis after CAS. The aim of this study was to analyze the rate and predictors of restenosis after CAS. 241 patients with carotid artery stenosis treated with stenting were analyzed retrospectively to identify patients who had restenosis after stenting. Univariate analysis and multivariate logistic regression were conducted to determine the predictors of restenosis. Mean patient age was 67.5 years. 8.3% of patients who underwent CAS had carotid restenosis of ≥50% during follow-up. 3.7% of patients required retreatment. Mean duration from CAS to retreatment was 11 months. In multivariate analysis, the predictors of restenosis included history of cardiovascular disease (OR=8.88, p<0.001) and having a cerebrovascular accident (CVA) prior to stenting (OR=1.87, p=0.034). A higher percentage of preoperative carotid stenosis was associated with higher odds of restenosis in univariate analysis (p=0.04, OR stenosis ≥80%=5.7). Our results sug...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
