Brain natriuretic peptide as a surrogate marker for cardioembolic stroke with paroxysmal atrial fibrillation.
Cardioembolic stroke generally results in severer disability, since it typically has a larger ischemic area than the other types of ischemic stroke. However, it is difficult to differentiate cardioembolic from noncardioembolic stroke (atherothrombotic and lacunar stroke), whenever ischemic stroke patients have sinus rhythm at the time of presentation. ⋯ From our results, it was suggested that the first-day brain natriuretic peptide and left atrial appendage flow measurements would be helpful in differentiating cardioembolic stroke with atrial fibrillation from noncardioembolic stroke.

Multicenter Study Comparative Study Controlled Clinical TrialInitiation of oral anticoagulation after acute ischaemic stroke or transient ischaemic attack: timing and complications of overlapping heparin or conventional treatment.
Oral anticoagulation is highly effective for secondary prevention of cardioembolic strokes in patients with atrial fibrillation (AF). There are no studies investigating timing and complications of different strategies for initiation of oral anticoagulation after acute stroke or transient ischaemic attack (TIA). ⋯ Initiation of oral anticoagulation after acute ischaemic stroke yielded low complication rates independent of antithrombotic co-medication. Heparin bridging was associated with a longer stay in acute care hospitals.

Review Case ReportsCerebral vasculitis and stroke in Lyme neuroborreliosis. Two case reports and review of current knowledge.
We report on 2 patients with cerebral vasculitis and stroke due to Lyme neuroborreliosis (LNB). Both patients had a prodromal stage involving headaches, and showed meningeal enhancement in addition to ischemic infarctions on brain magnetic resonance imaging and diffuse vasculitis on vascular imaging. ⋯ Stroke physicians should be aware of this rare presentation of LNB. A review of the current knowledge on cerebral vasculitis due to LNB is provided.

Cardiac arrhythmias after subarachnoid hemorrhage: risk factors and impact on outcome.
Serious cardiac arrhythmias have been described in approximately 5% of patients after subarachnoid hemorrhage (SAH). The aim of this study was to identify the frequency, risk factors and clinical impact of cardiac arrhythmia after SAH. ⋯ Clinically important arrhythmias, most often atrial fibrillation or flutter, occurred in 4% of SAH patients. Arrhythmias are associated with an increased risk of cardiovascular comorbidity, prolonged hospital stay and poor outcome or death after SAH, after adjusting for other predictors of poor outcome.
