OBJECTIVE: To investigate the difference of heart rate variability (HRV) and serum creatine kinase isoenzyme (CK-MB) activity between right-sided and left-sided stroke, and the relative impact of cardiac autonomic imbalance and heart abnormality on death by serum CK-MB activity and fractal dimension (FD) detection in patients with stroke. METHODS: Three ...

BACKGROUND AND PURPOSE: Despite numerous studies, the role of patent foramen ovale (PFO) as a risk factor for stroke due to paradoxical embolism is still controversial. On the assumption that specific lesion patterns, in particular multiple acute ischaemic lesions on diffusion-weighted magnetic resonance imaging, indicate a cardioembolic origin, we compared ...

BACKGROUND AND PURPOSE: Early deterioration can occur after acute stroke for a variety of reasons. We describe a hemodynamic steal and associated neurological deterioration, the reversed Robin Hood syndrome (RRHS). We aimed to investigate the frequency and factors associated with RRHS. METHODS: Consecutive patients with acute cerebral ischemia underwent serial ...

Bites due to Russell's Viper (Daboia russelii) are common in Sri Lanka. Commonest haematological manifestation is consumptive coagulopathy and bleeding. Commonest neurological manifestations are ptosis, ophthalmoplegia and rarely respiratory failure which are due to presynaptic inhibition of neuromuscular transmission. There are no authenticated reports of acute ischemic strokes following bites ...

Lacunar stroke is common, but the etiology of the small vessel abnormality is unknown. Retinal vessels share ontogeny, size, and physiologic characteristics with cerebral small vessels, and retinopathy is associated with stroke. We compared retinal microvessel appearance as a surrogate for cerebral small vessels in patients with lacunar and large ...

Patent foramen ovale (PFO) is significantly associated with cryptogenic stroke (CS). However, even in patients with CS, a PFO can be an incidental finding. We sought to estimate the probability that a PFO in a patient with CS is incidental. A systematic search identified 23 case-control studies examining the prevalence ...

INTRODUCTION: Despite extensive inpatient workup including telemetry monitoring, a significant proportion of stroke is classified as cryptogenic at hospital discharge. It is possible that a significant proportion of cryptogenic stroke is a result of intermittent atrial fibrillation (AF). Thirty-day cardiac event monitors (30-DEM) may increase the rate of AF detection ...

OBJECTIVE: Currently, no practical biomarker is available for the diagnosis of acute ischemic stroke. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has being applied extensively to analyze large biomolecules such as proteins. The technique is likely to be of remarkable value as indicators of systemic processes such as atherosclerosis ...

In patients with hemispheric stroke, abnormal motor performances are described also in the ipsilateral limbs. They may be due to a cortical reorganization in the unaffected hemisphere; moreover, also peripheral mechanisms may play a role. To explore this hypothesis, we studied motor performances in 15 patients with hemispheric stroke and ...
