Carotid endarterectomy yields greater risk reduction for ipsilateral ischemic stroke when performed within two-weeks of the last cerebrovascular symptom than when performed two-weeks or more after the last symptom. However, additional benefit might be gained if carotid endarterectomy is performed earlier than within two-weeks. ⋯ The risk of recurrent ipsilateral ischemic stroke was high within the first days of the presenting event. Many recurrences would likely have been avoided if carotid endarterectomy had been performed within the first days of the presenting event.

Transcatheter aortic valve implantation is a novel therapeutic option for patients at high risk for surgical heart valve replacement that carries a risk for periprocedural stroke. ⋯ Periprocedural cerebral ischaemia following transcatheter aortic valve implantation is not uncommon, but most patients have good outcomes. There was no particular pre-transcatheter aortic valve implantation or procedural risk factor profile that increased the risk for periprocedural stroke. Further studies are warranted to examine whether patients that are at higher risk for developing stroke after transcatheter aortic valve implantation can be identified.

The prevalence rate of overweight and obese has been escalating over the past two decades in China. Even so, the association between obesity and stroke still remains unclear to some extent. ⋯ Our data suggest that body mass index was an independent risk factor for total and ischemic stroke but not for hemorrhagic stroke in both genders. Association between body mass index and stroke was extremely mediated by hypertension, diabetes, and heart disease. Decreased risk for the leanest group was confined to men.
