Abstract

Aims: We tried to determine the influence of age on complication rates of carotid artery stenting (CAS). Methods and results: Two thousand seven hundred eighty CAS procedures were included in the registry. Median age of the patients was 70.8 years, with a proportion of octogenarians of 11.2% and a significant increase between 1996 (5.9%) and 2005 (13.7%; P for trend = 0.002). In octogenarians, a symptomatic stenosis was a more frequent indication for CAS (60.7% vs. 48%, P < 0.001), the CAS procedure was aborted more frequently (6.9% vs. 2.2%; P < 0.001) and the duration of intervention was longer (Median 45 vs. 40 min; P = 0.008). Increasing age was associated with a significant increase in the in-hospital death or stroke rate (P for trend: 0.001). In-hospital death or stroke rate was also higher in octogenarians compared with younger patients (5.5 vs. 3.2%; P = 0.032, OR = 1.79; 95%CI: 1.04-3.06). Logistic regression analysis showed that age analysed as a continuous variable was a strong predictor of in-hospital death or stroke (P < 0.001), whereas octogenarians had only a trend towards a higher event rate (P = 0.062). Conclusion: CAS in octogenarians is performed in an increasing proportion of patients. In-hospital stroke or death rates increase significantly with older age; however, there was no excess complication rate in octogenarians. © The European Society of Cardiology 2006.
