Background
We present a single institution registry with the novel feature of 90-day outcome assessments on all hospitalized acute stroke patients, inclusive of every patient with a primary discharge diagnosis of transient ischemic attack (TIA), acute ischemic stroke (AIS), nontraumatic subarachnoid hemorrhage (SAH), and intracerebral hemorrhage (ICH).Methods
Patient data obtained in the HOPES registry include demographics, comorbid diagnoses, medications, health behaviors, laboratory values, imaging studies, vital signs, and outcome measures, most notably the modified Rankin Scale (mRS) at 90days.Results
From May 2016 to December 31, 2017, 1607 patients were enrolled in the HOPES registry. 90-day outcome assessments were captured on 1555 patients (97%): 1096 AIS, 230 ICH, 110 SAH, and 119 TIA patients. Mortality rates and 90-day outcomes were most favorable for TIA patients. Mortality and 90-day disability scores were poorest for patients in the ICH group.Conclusions
The inclusion of 90-day outcomes data will allow HOPES to stand apart among stroke registries as a new standard for stroke outcomes research. The registry will provide the necessary comprehensive data that the field needs as we transition our focus of stroke research to poststroke recovery. 相似文献2.

Background
Evidence from outside the typical clinical research setting, such as the real-world setting, complements evidence coming from randomized controlled trials. The purpose of this study was to evaluate all available evidence from the real-world observational trials about long-term outcomes of treatment with intravenous (IV) recombinant tissue-type plasminogen activator (rt-PA) compared with not treated with IV rt-PA (non-rt-PA) in patients with acute ischemic stroke.Methods
We searched PubMed and Embase until March 1, 2018 for observational studies reporting matched or adjusted results comparing IV rt-PA versus non-rt-PA in patients with acute ischemic stroke. Outcomes assessed included all-cause mortality, hospital readmission rates, and independence rates. Hazard ratios with 95% confidence intervals were used as a measure of comparing between patients treated with IV rt-PA and non-rt-PA.Results
Six observational trials with 16,399 participants were identified. The use of IV rt-PA in acute ischemic stroke patients was associated with a lower risk of mortality (hazard ratio .61; 95% confidence interval, .52-.70; P < .00001), and there was no heterogeneity across trials. There was no evidence of an effect on hospital readmission rates and independence rates.Conclusions
IV rt-PA is associated with reduced long-term mortality in acute ischemic stroke patients. 相似文献3.

Background
Thrombolytic therapy in patients with pre-existing disability presenting with acute ischemic stroke (AIS) is controversial because of concerns regarding poor outcomes and futility of treatment. We hypothesized that a similar proportion of patients with and without pre-existing disability would return to their premorbid functional status following thrombolysis.Methods
This was a retrospective study at a single high-volume academic primary stroke center. All patients with AIS treated with intravenous alteplase between January 2005 and July 2016 were included. Premorbid functional status was assessed using modified Rankin scale (mRS) and dichotomized as independent premorbid (mRS 0-1) or disabled premorbid (mRS 2-4) groups for comparison. Functional outcome was assessed by mRS at 90 days and compared between groups.Results
Six hundred eighty patients independent premorbid (mean age 71.8 ± 13.1 years, 57.9% male) and 140 disabled premorbid (mean age 82.1 ± 8.7 years, 40.7% male) were included. Patients with pre-existing disability were older and had more vascular risk factors and more severe stroke on presentation (P < 0.05). A greater proportion of patients in the disabled premorbid group were dead at 90 days (35.7% versus 12.8%, P < 0.05). At 90 days, among patients with premorbid mRS 0, 1, 2, 3, and 4: 25%, 38%, 32%, 30%, and 25% of them returned to their respective premorbid mRS status.Conclusions
Irrespective of premorbid functional level, approximately one fourth to one third of thrombolyzed patients had returned to their premorbid functional levels at 90 days. Thrombolytic treatment should be considered in patients with mild-to-moderate pre-existing disability, taking into account the value placed on the chance of a return to premorbid functional status. 相似文献4.

Background and Aim
Stroke is a major health problem. Several studies reported sex differences regarding stroke. We aim to study this issue in an incidence stroke study.Methods
Data were retrieved from a community-based prospective register of patients that had a first ever stroke in a life time between October 2009 and September 2011. We studied sex differences regarding demographic data, vascular risk factors, stroke type, stroke severity (NIHSS), disability at 28days (modified Rankin scale (mRS)), and case fatality at 30 and 90days.Results
From 720 stroke patients, 45.3% were men. Women were older (75.0 ± 13.6 versus 67.2 ± 14.9 years), had a worse premorbid mRS (39.3% versus 25.5%, P < .001), and a higher prevalence of hypertension (P?=?.004) and atrial fibrillation (P < .001). Previous myocardial infarction was more frequent in men (P?=?.001), as well as smoking habits (P < .001). Ischemic stroke was more common in women than men (87.6% versus 81.3%, P?=?.038). The 28 days’ outcome was worse in women (mRS ≥ 2, 77.2% versus 70.6%, P?=?.044). No differences were found in initial stroke severity (median NIHSS?=?4) and case fatality at 30 and 90days, after adjusting for age and premorbid mRS.Conclusion
No differences were found in stroke initial severity and mortality at 30 and 90days between men and women, despite the sex differences pertaining to the stroke profile—age, vascular risk factors, stroke type, and outcome. Our results are somewhat discrepant from those described in the literature; more research is needed to understand if this may be due to changes in stroke standard of care. 相似文献5.

Background
The intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator (rt-PA) therapy is safe and efficient during the treatment of acute ischemic stroke. Nonetheless, the different outcomes among various stroke subgroups have limited data with regard to the safety and efficacy of cryptogenic stroke (CS). The present study compared the safety and efficacy when IVT with rt-PA was used for the treatment of CS and the other stroke subtypes.Methods
This study classified the IVT with rt-PA patients within 4.5 hours after stroke onset, based on the trial of ORG 10172 in acute stroke treatment criteria in terms of diagnostic evaluation. The data were obtained from the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China database, a large multicenter prospective registry. A multivariable logistic regression model was employed to compare the differences between the subtypes in symptomatic intracerebral hemorrhage (sICH) within 7 days and studied the mortality and the outcome during 90 days.Results
In total, 1118 patients were recruited; of these, 131 (11.7%) suffered from CS and 987 (88.3%) with the other etiology. In the CS group, patients were younger than those in the other etiology groups (P < .001). Moreover, it had a lower prevalence of previous stroke (P?=?.0117), receiving antiplatelet drug in 24 hours prior to thrombolysis (P?=?.0017), and functional independence (mRS > 1 before stroke, P?=?.003). The CS group had lower blood pressure (systolic blood pressure P?=?.0001; diastolic blood pressure; P?=?.0212) before thrombolysis, atrial fibrillation (P < .001), and diabetes mellitus (P?=?.0005). Transient ischemic attack, hypertension, hyperlipidemia, blood glucose, receiving anticoagulants in 24 hours prior to thrombolysis, and standard dosage of rt-PA were equally distributed in both groups. After the adjustment of confounders between the CS and the other subgroups, no obvious differences were observed in sICH rate and mortality (P > .05) The CS patients exhibited excellent recovery (mRS, 0-1; 63.78%) and functional independence (mRS, 0-2; 74.8%) than the large artery atherosclerosis patients.Conclusions
IVT with rt-PA is a safe and effective method for the treatment of CS patients. 相似文献6.

Objective
We designed a computed tomography angiography (CTA)-based algorithm for patients presenting to hospital with a transient ischemic attack (TIA) which identified high-risk patients, as well as inpatient versus semiurgent outpatient management following MRI, and we hypothesised that this would be effective.Methods
Patients seen in the ED at the Royal Adelaide Hospital from March 3, 2012 to November 30, 2016 with TIA-like symptoms were assessed for a cardioembolic source (clinical assessment, electrocardiogram) and underwent intra and extracranial CTA. Patients with a referable >50% stenosis were admitted and given dual antiplatelets. Most high-risk cardiac source patients were also admitted and anticoagulated. Other patients were loaded with aspirin, or changed to clopidogrel if on aspirin, and reviewed as outpatients following semiurgent MRI (3-4 days). We assessed the 90-day recurrent stroke risk in this cohort as a whole, and in those with a final cerebrovascular diagnosis.Results
1167 patients were diagnosed in Emergency as TIA and referred via our algorithm. A total of 150 were admitted, 78 had “high-risk” features. A total of 1017 patients were reviewed in the TIA clinic. The average age of the total cohort was 65.8 years old. Final diagnosis was TIA/minor stroke in 69% admitted patients and 30% clinic patients (P value < .0001). The 90-day recurrent stroke risk in these patients was 2.0% (5.8% admitted vs .7% clinic patients, P value < .0001). In those with noncerebrovascular diagnoses, there were no recurrent strokes within 90 days.Conclusions
Stroke risk is very low using CTA guided semiurgent clinic review algorithm. 相似文献7.

Background and Purpose
The association between thyroid hormone levels and long-term clinical outcome in patients with acute stroke has not yet been thoroughly studied. The purpose of the present study was to test the hypothesis that thyroid hormone levels are associated with 3-month functional outcome and mortality after acute stroke.Methods
We retrospectively analyzed 702 consecutive patients with acute stroke (251 women; median age, 73 years) who were admitted to our department. General blood tests, including thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4), were performed on admission. Neurological severity was evaluated using National Institutes of Health Stroke Scale (NIHSS) scores on admission and modified Rankin Scale (mRS) scores at 3 months after stroke onset. Poor outcome was defined as an mRS score of 3-5 or death. The impact of thyroid function on 3-month outcome was evaluated using multiple logistic regression analysis.Results
Poor functional outcome was observed in 295 patients (42.0%). Age (P < .0001), female sex (P < .0001), admission NIHSS score (P < .0001), smoking (P?=?.0026), arterial fibrillation (P?=?.0002), preadmission mRS (P < .0001), estimated glomerular filtration rate (P?=?.0307), and ischemic heart disease (P?=?.0285) were significantly associated with poor functional outcome, but no relationship between FT4, TSH, and poor functional outcome was found. A multivariate logistic regression analysis showed that low FT3 values (<2.00 pg/mL) were independently associated with poor functional outcome (odds ratio [OR], 3.16; 95% confidence interval [CI], 1.60-6.24) and mortality (OR, 2.55; 95% CI, 1.33-4.91) at 3 months after stroke onset.Conclusions
Our data suggest that a low FT3 value upon admission is associated with a poor 3-month functional outcome and mortality in patients with acute stroke. 相似文献8.

Background and Purpose
Cerebral edema is associated with poor outcome after IV thrombolysis. We recently described the TURN score (Thrombolysis risk Using mRS and NIHSS), a predictor of severe outcome after IV thrombolysis. Our purpose was to evaluate its ability to predict 24-h cerebral edema.Methods
We retrospectively analyzed data from 303 patients who received IV rt-PA during the NINDS rt-PA trial. Measures of brain swelling included edema, mass effect and midline shift assessed at baseline, at 24 h and new onset at 24 h. Outcome was assessed using intracerebral hemorrhage (ICH), symptomatic intracerebral hemorrhage (sICH), 90-day severe outcome, and 90-day mortality. Statistical associations were assessed by logistic regression reporting odds ratios (OR) and by areas under the receiver operating characteristic curves (AUROC).Results
Baseline brain swelling did not predict poor outcome; however, 24-h brain swelling predicted ICH (OR 5.69, P < 0.001), sICH (OR 9.50, P = 0.01), 90-day severe outcome (OR 7.10, P < 0.001), and 90-day mortality (OR 5.65, P = 0.01). Similar results were seen for new brain swelling at 24 h. TURN predicted 24-hour brain swelling (OR 2.5, P < 0.001; AUROC 0.69, 95 % CI 0.63–0.75) and new brain swelling at 24 h (OR 2.1, P < 0.001; AUROC 0.67, 95 % CI 0.61–0.73).Conclusions
Cerebral edema at 24 h is associated with poor outcome and 90-day mortality. TURN predicts ischemic stroke patients who will develop 24-h cerebral edema after IV thrombolysis.9.

Background
In acute stroke randomized trials, missingness of final functional outcome data reduces study power and potentially biases findings of treatment effect. Best methods for handling missing outcome data have not been well delineated for diseases with monophasic onset and subsequent improvement, like acute stroke.Methods
We simulated data missingness in the public dataset of the landmark, second NINDS-tPA trial, by randomly removing 5%-25% of actual values for the 3-month modified Rankin Scale (mRS) of global disability. We evaluated 5 missing data-handling methods: complete case analysis (CCA), worst case imputation (WCI), last observation carried forward (LOCF), multiple imputation using baseline covariates only (MI-B), and multiple imputation using baseline and postbaseline observations (MI-BP).Results
With the original trial's 333 patients, tissue plasminogen activator was associated with 3-month disability benefit, both for mRS dichotomized at 0-1 (P = .014) and shift analysis (P = .035). Distance (root mean square error) of imputed from actual mRS values was best for LOCF (1.17) and MI-BP (1.28), intermediate for MI-B (1.89) and worst for WCI (3.77). Directional bias (mean difference) was least for MI-BP (.01) and MI-B (?.16), intermediate for LOCF (?.37), and worst for WCI (?3.22). Preservation of formally positive results was greatest for MI-BP and LOCF (preserved at all missingness rates), intermediate for CCA and MI-B (preserved only with missingness <10%-20%), and least for WCI (preserved only with missingness <5%-20%).Conclusions
For acute stroke trials, multiple imputation using baseline and postbaseline observations is an advantageous approach to missing outcome data-handling, yielding high accuracy, reduced directional bias, and greater preservation of study power. 相似文献10.
Upper Limb Ischemic Postconditioning as Adjunct Therapy in Acute Stroke Patients: A Randomized Pilot
Yuejuan Li Keke Liang Long Zhang Yamei Hu Yunli Ge Jianhua Zhao 《Journal of stroke and cerebrovascular diseases》2018,27(11):3328-3335
Objective
This study aims to observe the clinical effect of upper limb ischemic postconditioning (LIPostC) as an adjunct to treatment with acute stroke patients, possibly due to increased cerebral perfusion.Methods
We perform a randomized blinded placebo controlled trial in nonthrombolysis patients with acute ischemic stroke, within 72hours of ictus, divided into the LIPostC group and control group. The LIPostC group is induced by 4 cycles of intermittent repeated limb ischemia: alternating 5 minutes inflation (20mm Hg above systolic blood pressure) and 5 minutes deflation performed manually using a standard upper arm blood pressure cuff in the nonparetic arm. The control group receives a sham procedure (cuff inflation to 30mm Hg). Patients underwent the intervention from the time of enrollment to Day 14. Comparison of National Institutes of Health Stroke Scale (NIHSS) score, cerebral infarction volume, relative Perfusion weighted imaging (PWI) parameters (regional relative cerebral blood flow, regional relative mean transit time; preintervention [day 0], day 14, day 90), modified Rankin Scale (mRS; the preintervention score [day 0], the curative ratio at day 90 [we define 0-1 score as close to recovery or full recovery]).Results
Sixty eligible patients with acute stroke (29 LIPostC and 31 control) are recruited age 65years (SD 12.22), blood pressure 156/74mm Hg (SD 14/10), and NIHSS score 5.98 (SD 3.35), mRS score 2.25 (SD .79). Only 1 in the LIPostC group is intolerant the first cycle to give up. All patients tolerate the sham procedure. Two patients experience recurrent stroke versus none in the LIPostC group. Day 90, compared with the control group, there is a significant decrease the NIHSS score, regional relative mean transit time (P < .05) and increase the curative ratio of mRS, regional relative cerebral blood flow(P < .05) in the LIPostC group, which infarct volume decreased by 31.3% (P < .05).Conclusions
LIPostC after acute stroke is well tolerated and appears safe and feasible. LIPostC may improve neurological outcome, and protective mechanisms may be increased cerebral blood flow to improve cerebral perfusion. A larger trial is warranted. 相似文献11.

Objective
To assess the long-term functional outcome of stroke in patients treated with mechanical thrombectomy (MT) performed during work hours (on-hours) versus after-hours, weekends, and official holidays (off-hours).Methods
Data on all patients receiving MT at a comprehensive stroke center was collected between December 2014-December 2016. Our primary outcomes were the discharge and 90-day modified Rankin Scale (mRS). We developed propensity scores for off-hours treatment and used inverse probability of treatment weights to address confounding. We estimated logistic regression to assess the relationship between off-hours treatment and favorable patient outcomes. Independent variables include receiving thrombectomy during the off-hours, admission National Institute of Health Stroke Scale (NIHSS), door to groin time in minutes, age, and race.Results
During the study period, 80 (41%) patients underwent thrombectomy during on-hours and 116 (59%) during off-hours. Mean age was 69.1 years for the on-hours group and 64.1 years for the off-hours group (P?=?.02). There were no statistically significant differences in median admission NIHSS, rate of alteplase administration, mean time from last known well to thrombectomy, rate of revascularization, and rate of hemorrhagic transformation between the 2 groups. Logistic regression analysis showed the probability of a favorable outcome at discharge (mRS ≤ 2) is 12.6 % lower for off-hours patients (P?=?.038, [95%CI ?.25 to ?.01]). For patients with a 90-day mRS (n?=?117), the probability of a favorable outcome was 18.7% lower for those treated during the off-hours (P?=?.029, [95%CI ?.36 to ?.02]).Conclusions
There is a higher probability of a good functional outcome in acute ischemic stroke patients who receive MT when performed during regular work hours. 相似文献12.

Introduction
Obstructive sleep apnea (OSA) is a well-known risk factor for stroke. This is attributed to multiple mechanisms such as endothelial dysfunction, atrial fibrillation, hypertension, and comorbid obesity. STOP questionnaire alone is unreliable to diagnose OSA and in-hospital sleep study is costly and can be technically challenging. We used high-resolution pulse oximetry (HRPO) to test the feasibility of screening for OSA and predicting outcome.Methods
Data from 115 stroke patients who underwent HRPO was collected including Oxygen desaturation index (ODI) <4%, pulse rate, arterial oxygen saturation (SaO2), and time spent at SaO2 saturation <88%. We also collected data on various confounders. The outcomes measured were NIHSS (National Institutes of Health Stroke Scale), mRS (modified Rankin Score) on discharge, and discharge disposition.Results
Overall 115 patients with valid HRPO data were included in the study. Mean age was 64±12years with 68% white, 22% black, and 10% Hispanic population. Of this cohort of 115 patients, 56% were males. Of the subjects enrolled 22 had atrial fibrillation, 27 had type 2 diabetes, 7 had resistant hypertension, and 7 had patient foramen ovale. Of the 115 patients, 75 patients were found to have ODI of >10 and the mean ODI was 29±30. The NIHSS on admission was 6.14±6.93 and on discharge was 4.46±4.59, mRS on discharge was 1.70±1.67 with 52% being discharged home, 43% to rehab, 2% nursing home, and 3% to long-term acute care facility. In this study, we show a strong association between atrial fibrillation and increasing ODI (P<.001, OR 1.01, CI 1.00-1.03). In addition, our study also shows an association between discharges outcome of rehab (more deficits leading to higher disability) versus discharge to home (lesser deficits) if ODI was ≤10 (P?=?0.005, OR 3.76, CI 1.49-9.52).Conclusions
Our study showed that there is a significant burden of OSA in acute stroke patients. ODI emerged as a predictor of atrial fibrillation and discharge disposition in our study. HRPO may be a cost-effective tool to screen and evaluate for OSA in acute stroke patients. 相似文献13.

Background
Acute ischemic stroke (AIS) has a higher morbidity and mortality rate. Many prediction tools have been developed to predict the risk of poor outcomes in patients after AIS, such as the THRIVE score, the iScore score, and the ASTRAL score. However, the predictive value of above 3 prediction tools in Chinese patients with AIS need to be further verified. So, this study aimed to determine the ability of the THRIVE score, the iScore score, and the ASTRAL score in predicting clinical poor outcomes in Chinese patients with AIS at 1 year.Methods
A total of 772 patients with AIS were included in this study. The baseline data of all patients were collected. The THRIVE score, the iScore score, and the ASTRAL score were calculated. All patients were followed up at 1 year. The poor outcome was defined as death, moderate/severe disabilities (modified Rankin scale, mRS > 2), most severe disability (mRS ≥ 5). Model discrimination was quantified by calculating the area under the receiver operating characteristic curve (AUC). The calibration was assessed using Hosmer–Lemeshow goodness-of-fit test and Pearson correlation coefficient.Results
We identified 576 (74.6%) patients with good prognosis and 196 (25.4%) patients with poor prognosis. AUC values of THRIVE score in predicting 1-year poor prognosis was lower than the iScore score and the ASTRAL scores (P < .05). The chi-square values of Hosmer-Lemeshow for the 3 prediction tools were 2.114, 4.877, 5.838 (all P < .05), respectively. There was a high correlation between the observed and the expected poor prognosis (Pearson correlation coefficient, .985, .693, and .620; all P < .05). AUC values of THRIVE score in predicting 1-year mortality and severe disability were lower than the iScore scores (all P < .05).Conclusions
The iScore score and the ASTRAL score reliably predict 1-year poor outcomes in Chinese patients with AIS, and the iScore score can accurately predict 1-year mortality and severe disability in Chinese AIS patients. 相似文献14.

Purpose
To examine telemedicine as it applies to acute ischemic stroke care at a spoke hospital and the effect on patient outcomes, including the timeliness of response, quality of care, safety, morbidity, and mortality when compared to standard hub hospital stroke center care.Methods
Retrospective review of prospectively entered quality/performance stroke/telestroke patient catalog data were completed for 1000 adult patients who presented with an acute ischemic stroke to the Mayo Clinic Hospitals (500 patients) or to one of thirteen Mayo Clinic affiliated telestroke spoke hospitals in the regions (500 patients). The primary outcome of interest was the percentage of accurate decision making for eligibility of IV alteplase administration assessed by blinded adjudication and the secondary outcomes pertained to complications, discharge parameters, and standard quality metrics.Results
There was no difference in the spoke hospital versus hub hospital groups in identifying and making the correct decision regarding which patients were eligible for IV alteplase administration (96% [95% confidence interval (CI): 94%-97%] versus 97% [95% CI: 95%-98%]; P?=?0.32). There was no difference among the groups in proportion receiving IV alteplase, sustaining symptomatic intracranial hemorrhage, and mortality. Patients in the spoke group were less likely to have a favorable outcome at discharge, as defined by National Institutes of Health Stroke Scale (NIHSS): 0-1 or mRS: 0-1 or Glasgow Outcome Scale (GOS): 0-1 (21% versus, 35%; P < 0.001), were less likely to have venous thromboembolism prophylaxis (46% versus 63%; P < 0.01), were less likely to have received antithrombotic therapy (85% versus 90%; P?=?.02), were less likely to be discharged on anticoagulation when indicated (56% versus 64%; P?=?.01), and were less likely to be prescribed cholesterol reducing treatment (68% versus 72%; P < .001). The initial acute care hospital length of stay was longer for the spoke hospital group by one day (median: 4 versus 3; P < .001).Conclusion
The key findings were that evidence-based stroke thrombolysis eligibility decision making, thrombolysis administration, and thrombolysis emergency stroke metrics were uniformly excellent for the spoke hospital group when compared to the standard hub hospital group. However, evidence-based stroke hospitalization and discharge metrics were inferior for the spoke hospital group when compared to the standard hub hospital. 相似文献15.

Background
Blood pressure (BP) is an important determinant of functional outcome in acute ischemic stroke (AIS) patients treated with intravenous tissue plasminogen activator (IV-tPA). Current guidelines recommend a BP target of 185/110 mmHg before IV-tPA bolus and maintaining it at less than 180/105 mmHg for the first 24 hours. However, the effect of blood pressure on various outcome measures after systemic thrombolysis remains unclear.Methods
Following a systematic search of Medline and EMBASE, all observational studies reporting effect of pretreatment BP on 90-day functional outcome as measured by the modified Rankin Scale (mRS) and/ or incidence of symptomatic intracranial hemorrhage (sICH) in AIS patients receiving thrombolytic therapy were included.Results
Of 2181 studies screened, 26 studies, involving 38,937 subjects, met inclusion criteria. Higher prethrombolysis systolic BP was significantly-associated with poorer 90-day functional outcome (Mean difference 3.87 mmHg; 95% confidence interval [CI] 1.18-6.56) and increased incidence of sICH (Mean difference 5.31; 95% CI 2.22-8.40). When studies were stratified by different cut-offs for functional outcome (mRS 0-1 versus 0-2) and definitions of sICH used (Randomized controlled trials or SITS-MOST), there was no significant difference in mean difference between the subgroups.Conclusions
Our data showed that higher prethrombolysis SBP was associated with poorer outcomes in thrombolysed acute ischemic stroke patients. This may suggest that more aggressive lowering of BP below the current recommendations prior to thrombolysis could be beneficial. The effect of early BP trends after tPA infusion could not be evaluated due to limited available data. Ongoing randomized clinical trials, like ENCHANTED, may provide further insights into the current guidelines and optimal BP levels. 相似文献16.

Objective
Endovascular thrombectomy (ET) for acute ischemic stroke (AIS) due to large-vessel occlusion (LVO) is offered to select patients meeting strict criteria. One of the criteria is stroke severity as indicated by the National Institute of Health Stroke Scale (NIHSS). Inherently, NIHSS is biased towards left hemisphere strokes (LHS) with median NIHSS score 4 points higher than right hemisphere strokes (RHS). This may potentially affect clinical decision making and thrombectomy eligibility. We sought to test this hypothesis.Methods
Data were analyzed from consecutive AIS patients with LVO admitted to our comprehensive stroke center (June 2015-December 2016). Following variables were studied: NIHSS score, occlusion location, time to presentation, and treatment received.Results
Three hundred and fifty-one proximal-anterior circulation LVOs (ACLVO) were identified. 211 patients harboring a proximal ACLVO, were treated <24-hour from symptom onset, had a baseline mRS 0-1, ASPECTS ≥6, and NIHSS score ≥6. One hundred and twelve (53%) were LHS and 99 (47%) were RHS. ET was performed in 87% of LHS and 78% of RHS (P = .09). In the NIHSS score >12 range, 88% of LHS and RHS received ET (P = .93). In the NIHSS score 6-12 range, 81% of LHS and 52% of RHS received ET (P = .03).Conclusions
We find comparable rates of ET between right and LHS in patients with high NIHSS but lower rates of ET of RHS than LHS in patients at lower NIHSS. A hemisphere-laterality based adjustment to the NIHSS may better identify the full extent of patients that may benefit from ET. 相似文献17.

Background
Using high-resolution magnetic resonance imaging (HR-MRI), we investigated the impact of basilar artery plaques that were not detected by magnetic resonance angiography (MRA) on the functional outcomes of patients with acute pontine infarction.Methods
A total of 40 patients with acute pontine infarction and normal basilar findings on MRA prospectively underwent HR-MRI for detection of basilar artery plaques. A relevant plaque was defined as one on the dorsal side of basilar artery, the same side of the ischemic lesion, and the same axial slices of the ischemic lesion. We analyzed the relationship between the relevant basilar artery plaques and the functional outcomes at 3 months.Results
The initial National Institutes of Health Stroke Scale score (3.5 versus 2.0, P?=?.012), and the incidences of neurological deterioration (42.9% versus 6.3%, P?=?.031) and unfavorable functional outcome (71.4% versus 12.5%, P?=?.001) were higher in patients with relevant basilar artery plaques than in those without. On multiple regression analysis, the relevant basilar artery plaque was a significant and independent predictor of unfavorable functional outcome (odds ratio, 6.662; 95% confidence interval, 1.117-39.735; P?=?.037).Conclusions
The presence of a relevant basilar artery plaque was closely related with unfavorable functional outcome in patients with acute pontine infarction even if the patients’ MRA showed normal basilar findings. 相似文献19.

Background
Several studies have shown that high level of plasma C-reactive protein (CRP) is associated with stroke outcomes and future vascular events, and a decrease in serum triiodothyronine (T3) was reported to be associated with stroke severity and poor prognosis.Objective
The goal of this study is to evaluate CRP and T3 as independent predictors of poor functional and cognitive outcomes in patients with acute ischemic stroke at hospital discharge.Methods
This study evaluated 120 patients who were admitted to the Clinical Hospital of Neurology and Psychiatry Brasov, between July 2016 and January 2017. The patients were evaluated for clinical stroke severity (National Institutes of Health Stroke Scale) and serum CRP and total T3 were evaluated on admission. Functional outcome and cognitive outcome were evaluated at discharge.Results
The severity of NIHHS scores were associated with higher CRP levels (β?=?.583, P = .000) and lower T3 concentration (β = ?.185, P?=?.043). Poor cognitive prognosis was associated with CRP levels (β?=?.441, P?=?.000) but not with T3 concentrations (P?=?.142). Poor functional outcome was associated with higher CRP levels (β?=?.457, P?=?.000), but not with T3 concentrations (P?=?.100). Using CRP and T3 as prognostic factors resulted in a probability of 53.5% to predict a poor functional outcome and of 80.42% to predict a poor cognitive outcome in stroke patients at discharge.Conclusions
The study showed that higher CRP and lower T3 levels were associated with stroke severity on admission. Functional outcome is likely secondary to stroke severity but functional outcome at discharge was associated with higher CRP levels and not with T3 concentration. Cognitive outcome was associated with higher CRP levels and not with T3 concentration. 相似文献20.
