Abstract

Introduction:There is significant evidence suggesting the predictive value of worsening carotid artery stenosis. We examined the impact of disease progression in patients with asymptomatic carotid artery stenosis on the incidence of ischemic stroke.Hypothesis:We believe carotid artery disease progression is a risk factor for ischemic stroke.Methods:We retrospectively evaluated 499 carotid artery doppler ultrasounds (CDU) without severe ICA stenosis at baseline performed at a single academic medical center between 2008 and 2011. The studies analyzed all had at least one subsequent CDU 11 months later for evaluation of disease progression. Symptomatic patients (stroke or TIA within 6 months) and carotid arteries with prior intervention were excluded. Baseline demographic and clinical data were recorded. Progression on CDU was defined as progression of disease to a higher category of stenosis that was at least 50% (moderate [50-79%], severe [80-99%], or occluded [100%]). The primary outcome assessed was the incidence of ipsilateral ischemic stroke as diagnosed with radiography (CT or MRI). Univariate logistic regression analysis was performed to evaluate for differences in the incidence of stroke between those CDU with and without evidence of disease progression.Results:Of the 499 CDU evaluated, 408 were negative for progression, while 91 showed evidence of disease progression. Those with disease progression did not have a significant increase in the incidence of stroke as compared to those without progression (1.1% vs 3.69%, P = 0.206).Conclusions:Carotid artery stenosis progression does not appear to have a significant role in the incidence of ipsilateral ischemic stroke. Thus, our study suggests the importance of investigating other factors that may better predict the risk for stroke in patients with asymptomatic carotid artery stenosis at baseline.
