Predictors of Occult Atrial Fibrillation in One Hundred Seventy-One Patients with Cryptogenic Transient Ischemic Attack and Minor Stroke.
Recent randomized studies have shown the potential of prolonged cardiac rhythm monitoring to detect silent paroxysmal atrial fibrillation (PAF) in patients with cryptogenic stroke. Our aim was to identify clinical and magnetic resonance imaging (MRI) factors that predict the detection of PAF during long-duration rhythm cardiac Holter (LDRCH) monitoring. ⋯ LDRCH is a noninvasive and inexpensive test with a high rate of AF detection in patients with cryptogenic stroke or transient ischemic attack. Occult PAF was more commonly diagnosed in older patients with premature atrial complex on the baseline electrocardiogram, left ventricular hypertrophy on echocardiography, and with previous white matter lesions on brain MRI.

Comparative StudyFocal Neurological Deficit at Onset of Aneurysmal Subarachnoid Hemorrhage: Frequency and Causes.
Focal neurological deficit (FND) is a recognized presenting symptom of aneurysmal subarachnoid hemorrhage (SAH). However, little is known on how often aneurysmal SAH patients present with FND and what the responsible mechanisms are. The aim of this study was to examine the frequency and causes of FND at onset in aneurysmal SAH. ⋯ One in every 10 aneurysmal SAH patients presents with FND. FND at presentation has diverse mechanisms, is not associated with a specific aneurysm location, and is independently associated with poor outcome.
