Abstract

Background Carotid artery stenting (CAS) is now being widely used in the treatment of carotid artery stenosis. Recent clinical studies have demonstrated low adverse event rates after CAS. This study evaluates the 30-day and 1-year results in patients treated with CAS and receiving intensive medical therapy in a high-volume percutaneous coronary intervention center. Methods A total of 184 patients underwent CAS between January 2011 and December 2013. In addition to antiplatelet therapy, patients received intensive antihypertensive treatment, high intensity statin and heart rate normalization therapy. Patients were stratified according to age and symptomatic status. Results Most of the patients (86.4%) had at least one high surgical risk criteria. The procedural success rate was 98.4%. The 30-day and 1-year incidence of stroke were 4.1% and 4.5%, respectively. At 30 days the combined rate of stroke/cardiovascular (CV) death/myocardial infarction (MI) was 5.8% and 10.9% in 1 year. The 30-day incidence of stroke/CV death in asymptomatic and symptomatic patients was 5.4% and 4.2%, respectively. Age ≥80 years increased the risk of stroke/CV death/MI at 1 year (OR 4.41; 95% CI 1.06–18.36; P = 0.04). Conclusions The study demonstrated acceptable clinical outcome results in patients with high medical comorbidities treated with CAS and intensive medical therapy. Adverse event rate in symptomatic patients did not exceed the guideline recommended range while in asymptomatic patients it was increased.
