Stroke; a journal of cerebral circulation
-
The risk of stroke and death in patients with atrial fibrillation is strongly associated with age and concomitant comorbidities. The aim of this study was to examine the age dependence of risk factors for stroke and mortality in young patients with atrial fibrillation. ⋯ The CHA2DS2-VASc score is an applicable tool for all age groups and in nonvalvular atrial fibrillation patients<65 years old, the same risk factors apply.

Randomized Controlled Trial Multicenter Study Comparative Study
Intracranial hemorrhage among patients with atrial fibrillation anticoagulated with warfarin or rivaroxaban: the rivaroxaban once daily, oral, direct factor Xa inhibition compared with vitamin K antagonism for prevention of stroke and embolism trial in atrial fibrillation.
Intracranial hemorrhage (ICH) is a life-threatening complication of anticoagulation. ⋯ Among patients with atrial fibrillation treated with anticoagulation, the risk of ICH was higher among Asians, blacks, the elderly, and in those with previous stroke or transient ischemic attack, increased diastolic blood pressure, and reduced platelet count or serum albumin at baseline. The risk of ICH was significantly lower in patients with heart failure and in those who were randomized to rivaroxaban instead of warfarin. The external validity of these findings requires testing in other atrial fibrillation populations.

Review Meta Analysis
Cognitive impairment and risk of stroke: a systematic review and meta-analysis of prospective cohort studies.
Cognitive impairment is linked to vascular risk factors and brain vascular pathologies. Several studies have tested whether subjects with cognitive impairment have higher risk for stroke. The aim of this study was to systematically review available evidence on the association between cognitive impairment and risk of stroke to obtain precise effect estimates of the association and to identify which cognitive domains associate most with incident stroke. ⋯ Cognitive impairment is associated with higher risk of stroke. The associations were not significantly different for executive function, memory, and language.
