Randomized Controlled Trial Multicenter Study Comparative Study
Safety of stenting and endarterectomy by symptomatic status in the Carotid Revascularization Endarterectomy Versus Stenting Trial (CREST).
The safety of carotid artery stenting (CAS) and carotid endarterectomy (CEA) has varied by symptomatic status in previous trials. The Carotid Revascularization Endarterectomy Versus Stenting Trial (CREST) data were analyzed to determine safety in symptomatic and asymptomatic patients. ⋯ There were no significant differences between CAS versus CEA by symptomatic status for the primary CREST end point. Periprocedural stroke and death rates were significantly lower for CEA in symptomatic patients. However, for both CAS and CEA, stroke and death rates were below or comparable to those of previous randomized trials and were within the complication thresholds suggested in current guidelines for both symptomatic and asymptomatic patients.

Little is known about the role of microinfarcts in dementia and cognition. We examined microinfarcts and dementia, global cognition, and 5 cognitive systems in community-dwelling older persons. ⋯ Microinfarcts are common, and persons with multiple cortical microinfarcts have higher odds of dementia. Microinfarcts are also associated with lower cognition, specifically perceptual speed and semantic and episodic memory.

Comparative Study
Thrombolysis with intravenous tissue plasminogen activator predicts a favorable discharge disposition in patients with acute ischemic stroke.
Acute ischemic stroke patients who receive recombinant tissue plasminogen activator (rt-PA) within 3 hours of symptom onset are 30% more likely to have minimal to no disability at 3 months. During hospitalization, short-term disability is subjectively measured by discharge disposition, whether to home, inpatient rehabilitation, a skilled nursing facility, or subacute care. There are no studies assessing the role of recombinant tissue plasminogen activator use as a predictor of poststroke discharge disposition. ⋯ Patients who receive intravenous recombinant tissue plasminogen activator as treatment for acute ischemic stroke are more likely to be discharged directly home after hospitalization. This study is limited by its retrospective nature and the undetermined role of psychosocial factors related to discharge.
