See related article, pages 2379–2383. Unlike in acute myocardial infarction, the underlying pathophysiological mechanism of vascular arterial occlusion in acute stroke is heterogeneous. Composition of cerebral embolic material may vary, depending on specific endothelial and flow conditions of the embolic source. Old, platelet-rich, and well-organized thrombi formed under flow conditions have be...

BACKGROUND AND PURPOSE Premature ventricular complexes (PVCs) on a 2-minute electrocardiogram are a common, largely asymptomatic finding associated with increased risk of coronary heart disease and death. They may reflect atherosclerosis or other pathogenic pathways that predispose to arrhythmias and stroke. METHODS We conducted a prospective evaluation of the Atherosclerosis Risk In Communit...

Sixty-five consecutive patients with recent unequivocal TIA (33) or stroke (32), but nondiagnostic arteriograms, had two-dimensional echocardiograms (2DE) and electrocardiograms (ECG) to determine the incidence of cardiac abnormalities which could cause embolic stroke. Abnormalities were classified according to increasing probability of causing an embolic event: non-specific, possible emboligen...

Ischaemic stroke is a sudden neurological disorder caused by localised cerebral ischaemia and persistent infarction. Occlusion of large arteries due to atherothrombosis, embolism (i.e., embolic infarction), no thrombotic occlusion in small, deep lacunar stenosis proximal hypotension leading decreased blood flow arterial supply zones are the most common causes ischemic hemodynamic stroke). It no...

Embolic strokes of undetermined source comprise a subset of cryptogenic ischemic strokes. It is thought that some embolic strokes of undetermined source could be due to left atrial thromboembolism without atrial fibrillation. The authors sought to determine whether a marker of left atrial pathological changes could pose as a surrogate marker of nonarrhythmogenic atrial thromboembolism in emboli...

Application of commonly used volatile anesthetics after brain ischemia onset (post-treatment) provides neuroprotection in rodents. To further test its translational potential, this study was designed to determine whether isoflurane post-treatment induced neuroprotection in rabbits after embolic stroke. White male New Zealand rabbits received intra-carotid injection of clots when they were awake...

Isolated hand paresis is a rare presentation of stroke, which mostly results from a lesion in the cortical hand motor area, a knob-like area within the precentral gyrus. I report the case of a patient who experienced recurrent ischemic stroke alternately involving bilateral hand knob areas, causing isolated hand paresis. There was no abnormal finding on brain and neck magnetic resonance angiogr...
