Stroke and rheumatic heart disease: A systematic review of observational studies
Abstract: Ischemic stroke is a severe complication of rheumatic heart disease (RHD), but data about its incidence and case-fatality in RHD patients’ population is unclear. We aimed to perform a systematic review of the literature to better define the incidence, prevalence and case-fatality of stroke in patients with RHD, and to estimate the proportion of RHD in stroke population. We searched Ovid Medline, EMBASE, CBM, CNKI and VIP for observational studies published in English or Chinese reporting the association of stroke and RHD until April 2011. Two authors independently assessed each study for eligibility based on pr...

Atrial fibrillation predicts good functional outcome following intravenous tissue plasminogen activator in patients with severe stroke
Conclusion: Presence of AF was associated with favorable 90-day outcome following intravenous thrombolysis in patients with severe stroke at baseline, while the association did not exist in patients with mild stroke.

Which risk factors are more associated with ischemic rather than hemorrhagic stroke in black Africans?
Conclusions: With increasing proportion of the population over 61 years and better BP control, the proportion of IS is expected to rise in black African countries currently undergoing epidemiological transition (changing lifestyle/disease pattern). Therefore, relevant components of the stroke intervention quadrangle (stroke surveillance, acute care, preventive and rehabilitation services) should be tailored toward this need.

Microstructural tissue damage in normal appearing brain tissue accumulates with Framingham Stroke Risk Profile Score: Magnetization transfer imaging results of the Austrian Stroke Prevention Study
Conclusion: Increasing risk for stroke leads to microstructural brain changes invisible by standard MRI. The validity, the underlying pathogenic mechanisms and the clinical importance of these abnormalities needs to be further determined.

The value of the use of plasma B-type natriuretic peptide among acute ischemic stroke patients in a Chinese emergency department
In this study, 142 of 238 acute ischemic stroke patients met the study criteria [mean age 70.84±11.48 years, 74 (52.11%) female]. Of the 142 patients, 35.92% were diagnosed with LAA at discharge, 25.35% with CE, 27.46% with SAO, 11.27% with SOE or SUE. Age, previous cardiac disease, atrial fibrillation, the length of hospital stays, SSS score on admission≤25 and mRS≥3 or death at discharge were all significantly higher in the CE patients compared to other subtypes (p

The prognostic impact of the stroke unit concept after transient ischemic attack
This study compares the prognostic impact of the stroke unit concept with conventional care on patients with TIA.Methods: During a 30-month period (beginning April 2005), 878 patients (mean age, 70±12years; 44.3% female) with TIA admitted within 24h of symptom onset were prospectively evaluated. The adjusted logistic regression analyses were used to estimate the odds ratio for the stroke risk during hospitalization and the 90-day mortality.Results: Of 878 patients, 591 (67.3%) were treated in the stroke unit, and 287 (32.7%) underwent conventional care. Patients receiving stroke-unit care had significantly higher rates of...

Early corticospinal tract Wallerian degeneration on diffusion-weighted MR imaging after adult stroke: Three cases report
Ischemic stroke usually damages supratentorial motor systems which results in hemiparalysis. Both pediatric and adult studies have demonstrated that stroke-induced chronic descending corticospinal tract atrophy on MR imaging is consistent with Wallerian degeneration (WD) and that chronic WD is associated with poor motor outcome . Such findings of WD at chronic phase, however, are of limited clinical significance. Early WD of neonatal and pediatric stroke has been identified on diffusion-weighted MR imaging (DW-MRI) . In terms of early WD on DW-MRI in adult stroke, few case studies have been reported . Presented herein are ...

Early superficial temporal artery to middle cerebral artery bypass in acute ischemic stroke
Conclusions: In this study, which consisted of 20 carefully selected patients with acute ischemic stroke, an early STA–MCA bypass was safely and effectively performed, and in some cases, an early STA–MCA bypass resulted in rapid neurological improvement. An early STA–MCA bypass was beneficial in select patients who had acute ischemic stroke with imaging evidence of a small infarction.

Brain natriuretic peptide level on admission predicts recurrent stroke after discharge in stroke survivors with atrial fibrillation
Previous reports indicate that approximately 5–10% of patients with ischemic stroke in Japan experience a stroke recurrence within the first year [1,2]. Recurrent stroke results in further disabilities. Therefore, it is important to identify risk factors associated with recurrent stroke. Several factors have been shown to be associated with recurrent stroke including large artery atherosclerosis [3], diabetes mellitus [3], previous transient ischemic attack (TIA) [3], atrial fibrillation (AF) [3], hypertension [3], increasing age [3], fibrinogen levels [4,5], D-dimer levels [5], and C-reactive protein levels [6].

Long-term medication persistence in stroke patients treated with intravenous thrombolysis
Recurrent strokes constitute a notable proportion of all preventable strokes (up to 30%) and are more disabling, fatal and costly than the first stroke [1]. Strategies to reduce the increasing global burden of stroke include not only mass population high-risk approaches to prevent first-ever stroke but also the treatment of acute stroke patients and the secondary prevention of recurrent stroke. Preventive treatments such as medications and a healthy lifestyle have shown efficacy on stroke recurrence [2].

Prognosis of aphasia in stroke patients early after iv thrombolysis
Conclusion: EICs are not predictive of aphasia outcome and patients with improvement showed smaller infarct volumes. One third improved within 24h, while two thirds remained unchanged. This might justify a closer follow-up of aphasia in stroke patients at the acute stage.

A simple risk score for early ischemic stroke mortality derived from National Institutes of Health Stroke Scale: A discriminant analysis
Conclusions: The suggested discriminant function, comprising NIHSS items of level of consciousness-commands, language and gaze, can predict 28-day mortality after ischemic stroke in a similar way to the original NIHSS score and can provide a baseline for stroke severity in emergency settings.

Autonomic symptoms in hypertensive patients with post-acute minor ischemic stroke
Autonomic function is frequently altered in patients with ischemic stroke during acute and chronic stages. Cardiac arrhythmias and sudden death during acute stroke are related to autonomic function imbalance.[1–3] Non-invasive tests have suggested sympathetic hyperactivity and cardiovagal dysfunction in acute stroke [1,2,4–7] with diverse results when considering the influence of lateralization, site and sub-type of ischemic stroke [1–3,8]. Autonomic cardiovascular dysfunction is associated with stroke severity [8].
