Background
Antiplatelet therapy is a cornerstone prevention strategy for secondary ischemic stroke (IS) and transient ischemic attack (TIA). Yet, a proportion of patients who receive antiplatelet therapy experience recurrent ischemic cerebrovascular events. A recent meta-analysis found an increased risk of recurrent stroke in clopidogrel- or aspirin-treated patients with ischemic stroke who had high on-treatment platelet reactivity (HTPR). Few studies have focused specifically on clopidogrel HTPR. Therefore, the aim of this study was to examine the relationship between clopidogrel HTPR and recurrent ischemic events in a population of Danish patients with IS.Methods
We performed a prospective observational study to evaluate the relationship between HTPR defined as platelet reaction units >208 and a composite primary endpoint of recurrent stroke, TIA, acute myocardial infarction (AMI), or vascular death over a 2-year follow-up period.Results
A total of 142 patients were included in the final statistical analysis, but only 3 patients (2.1%) demonstrated clopidogrel HTPR. The median time of on-treatment platelet testing was 75 days. Recurrent IS, TIA, AMI, or vascular death occurred in 14 patients (10%). Of these, 1 new ischemic event (AMI) occurred in a HTPR patient. There was no difference in the frequency of new ischemic events between the HTPR and non-HTPR groups (P = .27); moreover, the number of patients with HTPR was too small for statistical analysis.Conclusions
Clopidogrel HTPR does not seem to be a major contributor to recurrent ischemic events in Danish ischemic stroke patients. 相似文献2.

Introduction and Study Aim
Embolic strokes of undetermined source (ESUS) represent a rather recent diagnostic entity under clinical research for relapse prevention in cryptogenic stroke patients. Despite strict diagnostic criteria, ESUS definition ignores major clinical and radiological aspects, so including heterogeneous cases and probably influencing trial results. This study researches clinically relevant phenotypes among ESUS patients.Patients and Methods
We evaluated ESUS patients admitted at Trento Stroke Unit over a 4-year period. Vascular risk factors (RFs), neurological deficit severity, presence of potential embolic sources, and ASCOD phenotype were recorded. Ischemic lesions were categorized considering their extension in 4 groups. Subgroup comparisons by predefined differences in age, amount of RFs, history of previous stroke, deficit severity, and stroke lesion extension were done.Results
ESUS cases were 86. Patients younger than 50 years old (n?=?17) had a lower prevalence of RFs, left atrial enlargement, left ventricle diastolic dysfunction, a higher proportion of ASCOD score A0 (P < .05). Patients without RFs (n?=?18) differed from those with greater than or equal to 3 RFs (n?=?23) for a younger age and a lower prevalence of potential causes of embolism (P < .05). Patients without a previous stroke (n?=?70) were younger, had a lower prevalence of RFs, left ventricle diastolic dysfunction, a higher prevalence of ASCOD score A0 (P < .05). No differences were observed comparing minor and major clinical and radiological strokes.Discussion and Conclusions
ESUS patients can be distinguished in 2 opposite phenotypes defined by a lower and a higher load of atherosclerotic pathology. They may suggest possible underlying pathogenic mechanisms and support interpretation of ongoing trials results. 相似文献3.

Background
Cancer treatment, specifically surgical intervention, as a possible stroke trigger is understudied.Methods
Using the Nationwide Readmissions Database and validated diagnosis and procedure codes, we identified adults with index admissions for colorectal surgery for colorectal adenocarcinoma (Group A) and compared them to admissions for colorectal surgery for benign conditions (Group B) and hepatobiliary or pancreatic surgery for benign conditions (Group C). Within the colorectal cancer cohort, we further identified patients who underwent open versus laparoscopic surgery. The primary outcome was readmission for ischemic or hemorrhagic stroke up to 1 year. Cumulative risk of ischemic stroke was calculated using risk survival statistics, and hazard ratios (HR) were calculated using adjusted Cox regression.Results
Patients in Group A had higher 3-month readmission rates for ischemic and hemorrhagic strokes than those in Groups B and C. Higher risk of ischemic stroke (HR 1.46, 95% confidence interval [CI] 1.20-1.79) in Group A compared to Group B was eliminated following adjustments for illness severity and vascular risk factors. Comparing types of colorectal surgical intervention for cancer, there was significantly greater risk of ischemic stroke with open versus laparoscopic surgery, despite adjusting for vascular risk factors (HR 1.70, 95% CI 1.15-2.52).Conclusions
We found elevated risk of ischemic stroke up to 1 year following open surgery for colorectal adenocarcinoma compared to laparoscopic. More research is necessary to clarify the underlying surgery-related mechanisms that contribute to elevated risk. 相似文献4.

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5.

Introduction
Immune thrombotic thrombocytopenic purpura (i-TTP), related to acquired ADAMTS-13 dysfunction, can lead to various neurological symptoms including ischemic stroke. To date the clinical, radiological, and biological characteristics of patients having a stroke as the inaugural manifestation of i-TTP are largely unknown.Methods
Probable immune-TTP was defined by a low ADAMTS-13 activity associated with the presence of ADAMTS-13 inhibitors and/or favorable clinicobiological response under immunological treatments. The clinical, radiological, biological data and outcome under treatment are described in a cohort of 17 patients coming from 3 local cases and a literature review.Results
Fourteen of the 17 patients were female and the mean age was 41 years. None of the patients had the classical pentad of TTP. Only 41% had a combination of thrombocythemia and hemolysis. Stroke was multifocal in 35% and included large artery strokes. No adverse event was observed following intravenous thrombolysis. Refractory and relapsing forms were observed in 47%.Discussion
The clinical, radiological, and biological presentation of patients with stroke as the inaugural presentation of i-TTP is heterogeneous. This diagnosis should be discussed in every young adult with ischemic stroke of undetermined source. 相似文献6.

Background
The clinical presentations and outcomes of patients with high-grade stenosis of internal carotid artery (ICA) are highly variable. We investigate the influence of different stroke severity on outcomes of ischemic stroke patients with high-grade stenosis of ipsilateral ICA.Methods
372 acute first-ever ischemic stroke patients with high-grade stenosis (70%-99%) or occlusion of ipsilateral ICA were enrolled and followed up for 5years. Stroke severities of the enrolled patients were grouped according to the Oxfordshire Community Stroke Project classification system as total anterior circulation infarcts (TACI) or non-TACI. Demographic features, vascular risk factors, comorbidities, and outcomes were compared between the 2 groups.Results
A total of 71 patients (19.1%) were presented with TACI. Of laboratory data, the values of white blood cell count and high-sensitivity C-reactive protein were significantly higher in patients with TACI (P?=?.008 and P?=?.003, respectively). Of clinical course, the occurrence of initial impaired conscious, stroke-in-evolution, pneumonia, gastrointestinal bleeding, and urinary tract infection were significantly higher in patients with TACI. The prevalence of dependent functional status was higher in patients with TACI. Multivariate Cox regression revealed that TACI is a significant predictor of 5-year all-cause mortality in first-ever ischemic stroke patients with high-grade stenosis of ipsilateral ICA (HR [hazard ratio] = 3.66, 95% confidence interval = 2.23-6.00, P < .001).Conclusions
TACI is associated with increased risk of 5-year mortality in ischemic stroke patients with high-grade stenosis of ipsilateral ICA. Intensive medical treatment for stroke prevention in patients with severe carotid artery stenosis is warranted. 相似文献7.

Objective
The aim of this prospective cohort study was to assess the incidence and risk factors of delirium following acute ischemic stroke, as well as its effects on functional outcome.Methods
Two hundred and sixty-one patients with acute ischemic stroke were screened for delirium during the first week after admission. Delirium was diagnosed according to the Confusion Assessment Method. If delirium was present, delirium rating scale-revised-98 was used to assess its severity. Neurologic deficits were assessed with the National Institutes of Health Stroke Scale (NIHSS). Brain magnetic resonance imaging assessment quantified the infarction, white matter lesions, and medial temporal lobe atrophy. Functional outcome assessment included the modified Rankin Scale and Lawton Instrumental Activities of Daily Living scale at 3 and 6 months after the index stroke.Results
Thirty-eight (14.6%) patients with acute ischemic stroke developed delirium during the first week of admission. Patients with poststroke delirium (PSD) were older, had higher NIHSS scores on admission, and were more likely to have a previous stroke, an infection, and a left cortical infarct. Furthermore, left cortical infarction, older age, severer neurological deficit and having a previous stroke increased the risk of PSD. PSD was associated with a worse functional outcome.Conclusion
The incidence of delirium was 14.8% in the first week after admission with acute ischemic stroke. Age, having a previous stroke, stroke severity, and left-cortical infarction were independently predictors of PSD. PSD may result in a significantly worse functional outcome. 相似文献8.
Purpose of Review
To summarize the literature on the detection of atrial fibrillation (AF) in patients with “cryptogenic” stroke, a cohort including about 25% of all ischemic stroke patients and patients with embolic stroke of undetermined source (ESUS).Recent Findings
A first episode of AF is detected in up to one third of cryptogenic stroke and in up to one fourth of ESUS patients during long-term monitoring. AF prevalence correlates to patient selection, duration, and quality of ECG monitoring. Higher rates of AF were reported in stroke patients with left atrial pathology, specific ECG alterations, or increased natriuretic peptides. While AF detection impacts on medical stroke prevention in the vast majority of patients, patient selection for prolonged monitoring is largely left at the physician’s discretion.Summary
AF detection after cryptogenic stroke or ESUS is a frequent, potentially causal condition. Whether subsequent oral anticoagulation may improve outcome remains open.9.

Objectives
To describe the neurological manifestations of invasive aspergillosis presenting with a focal neurological deficit compatible with an acute stroke.Materials and Methods
Retrospective analysis of a clinical series of patients between 2011 and 2017 with invasive aspergillosis and neurological symptoms compatible with an acute brain stroke. Clinical and epidemiological data, microbiological results, radiological findings, treatment, and course were recorded.Results
Five patients were selected with a mean age of 55.4years. All patients were immunosuppressed. In 4, systemic infection was unknown. In every case, neurology on call was alerted because of acute focal neurological symptoms. None of the patients received revascularization procedures. Galactomannan antigen was positive in all of the patients and culture was positive in 3. Mortality was 100% despite specific antifungal treatment.Conclusions
Acute stroke can be the first manifestation of disseminated aspergillosis. This form of presentation was frequent in our series and should be suspected in immunocompromised patients with acute neurological deficits. 相似文献10.

Background
Despite the use of validated prehospital stroke scales, stroke mimics are frequent among patients transported by Emergency Medical Services to the Emergency Department. We aimed to describe the frequency and characteristics of neurological and non-neurological mimics transported to a comprehensive stroke center for acute stroke evaluation.Methods
This was a retrospective analysis of a database consisting of all consecutive patients with suspected stroke transported to the Emergency Department of a comprehensive stroke center during an 18-month period. Hospital charts and neuroimaging were utilized to adjudicate the final diagnosis (acute stroke, stroke mimic, and specific underlying diagnoses).Results
Nine hundred fifty patients were transported with suspected stroke, among whom 405 (42.6%) were stroke mimics (age 66.9 ± 17.1 years; 54% male). Neurological mimics were diagnosed in 223 (55.1%) patients and mimics were non-neurological in 182. The most common neurological diagnoses were seizures (19.7%), migraines (18.8%), and peripheral neuropathies (11.2%). Cardiovascular (14.6%) and psychiatric (11.9%) diagnoses were common non-neurological mimics. Patients with neurological mimics were younger (64.1 ± 17.3 years versus 70.5 ± 16.1 years, P < .001) and had less vascular risk factors than non-neurological mimics. The proportion of non-neurological mimics remained high (38%) despite the use of a prehospital stroke identification scale.Conclusions
Stroke mimics are common among patients transported by Emergency Medical Services to a comprehensive stroke center for suspected stroke, with a considerable proportion being non-neurological in origin. Studies refining triage and transport of suspected acute stroke may be warranted to minimize the number of mimics transported by to a comprehensive stroke center for acute stroke evaluation. 相似文献11.

Goal
Epilepsy is a major complication of stroke. There have been suggestions that patients with cardioembolic stroke are at a greater risk of developing seizures than other stroke subtypes. However, the incidence of atrial fibrillation (AF) and cardioembolic stroke varies considerably across countries, generally higher in Western populations than in Asian populations. This study assessed whether ethnicity affects the association between AF and poststroke seizure (PSS) development. We hypothesized that Royal Melbourne Hospital ([RMH] Melbourne) patients will have significantly higher incidence of AF-related PSS than in the Jinling Hospital (Nanjing) population.Materials and Methods
This was a retrospective, multicenter cohort study including patients with anterior circulation ischemic stroke admitted between 2008 and 2015. Occurrences of PSS were ascertained by reviewing medical records or telephone follow-up. To test the hypothesis of an interaction between ethnicity and AF for PSS occurrence, a logistic regression model with AF and ethnicity together with an ethnicity-by-AF interaction term was used.Findings
Of 782 patients followed-up for seizure development at RMH, 247 (31.6%) patients had AF, of whom 10 (4%) developed PSS. Of 1185 patients followed-up and included at JH, 54 (4.8%) patients with AF, of whom 4 (7.4%) developed PSS. At RMH, no significant association was found between AF and PSS; odds ratio .75, 95% confidence interval .4-1.6, (P?=?.4). At JH, there was a significant association between AF and increased PSS: OR 4.0, 95% CI 1.3-12.1, (P?=?.01), P for interaction?=?.03.Conclusion
Further understanding of genetic risks and environmental differences across ethnic populations and the role in PSS is required. 相似文献12.

Objects
To identify predictors of acute ischemic stroke (AIS) among patients presenting to the Emergency Department (ED) with dizziness, imbalance, or vertigo (DIV) based on demographic and clinical characteristics.Methods
We identified patients admitted to the hospital after presenting to the ED with DIV from the Statewide Planning and Research Cooperative System database of New York from 2010 to 2014. Demographic and clinical characteristics were systematically collected. Multivariable logistic regression was used to determine predictors of a discharge diagnosis of AIS.Results
Among 77,993 patients with DIV, 3857 (4.9%) had a discharge diagnosis of AIS. Admission presentation of imbalance, African-American race, history of hypertension, diabetes mellitus, hypercholesterolemia, tobacco use, atrial fibrillation, and prior AIS due to extracranial artery atherosclerosis were each positively associated with an AIS diagnosis independently. Factors negatively associated with an AIS discharge diagnosis included: admission presentation of vertigo, female sex, age > 81, history of anemia, coronary artery disease, asthma, depressive disorders, and anxiety disorders.Conclusions
Multiple potential positive and negative predictive AIS risk factors were identified. Combining with currently available centrally-caused dizziness prediction tools, these newly identified factors could provide more accurate AIS risk stratifying method for DIV patients. 相似文献13.

Background
Cholesteryl ester transfer protein (CETP) plays a major role in the metabolism of high-density lipoprotein. Polymorphisms in the CEPT gene can affect susceptibility to atherosclerosis and cardiovascular disease. The aim of this study was to evaluate the association of the CETP I405V polymorphism with ischemic stroke.Methods
Five hundred eighty stroke patients and 505 healthy controls were involved in a study. Genomic DNA from all subjects was genotyped for the I405V polymorphism by polymerase chain reaction and restriction analysis.Results
The comparison of stroke and control groups showed a significant increase of V allele and VV genotype in stroke patients (OR 1.61, 95% CI 1.34-1.93 and 2.83, 95% CI 1.78-4.51, respectively). The distribution of alleles and genotypes was also compared between stroke patients with type 2 diabetes mellitus (T2DM) and patients without it. No statistically significant differences were observed between two subgroups. The OR for V allele was 1.15, 95% CI .91-1.46 and for VV genotype 1.25, 95% CI .73-2.15. In comparison of these subgroups separately with controls, the results were similar to obtained for entire STR group. When the distribution of I405V polymorphism in relation to T2DM was analyzed in subgroups of men (n?=?296) and women (n?=?284) no statistically significant differences were observed.Conclusion
Our results demonstrate that the I405V polymorphism in the CETP gene is strongly associated with ischemic stroke. The presence of T2DM did not affect this association. To our knowledge this is the first such association documented in Caucasian population. 相似文献14.
Background
Several studies have reported on predictors for caregiver burden in patients with stroke, but the magnitude of the impact of these variables remains unclear. The aim of the study was to determine the magnitude of relationship between each predictor and caregiver burden.Methods
Articles related to this filed were search in PUBMED, MEDLINE and Cochrane Library electronic database from the upset to May 2018. Of the 812 articles identified, 22 were included in the final analysis (3025 patients and 2887 caregivers). Weighted correlation coefficient (r-index) was computed as effect size for each predictor.Results
Of predictor variables of patients, the activity of daily living and anxiety had moderate to large effect sizes; gender, neurological function and depression had the small to moderate effect sizes. Of caregivers’ predictors, depression, anxiety, and sense of coherence had large effect sizes; gender, daughter in law, physical health and employment status had small to moderate effect sizes.Conclusions
The most powerful predictors of caregiver burden using meta-analysis were identified to direct future research and evidence-based practice. 相似文献15.

Objectives
Many patients admitted with an ischemic stroke or transient ischemic attack (TIA) undergo thrombophilia testing. There is limited evidence to support this practice. We examined the effect of thrombophilia testing on management of patients admitted with an ischemic stroke or TIA.Materials and Methods
In this retrospective observational single-center study, we identified patients who were admitted with stroke or TIA and underwent thrombophilia testing over a 45-month period. We reviewed their electronic medical records to assess whether testing affected clinical management, defined as anticoagulation treatment by the time of discharge due to a positive test result. Secondary endpoints included potential misdiagnosis due to false positive results and cost of testing.Results
Testing was performed in 143 patients with a stroke or TIA. Forty-four patients (31%) had at least 1 positive test result. The most common positive tests were an elevated factor VIII activity (18% of patients tested) and decreased protein S activity (11% of patients tested). Both of these tests are subject to acute phase effects. Testing altered clinical management in only 1 patient (1% of total patients tested). Thirty-three patients (75%) have the potential for carrying a misdiagnosis due to a positive test that was never repeated for confirmation or repeated too soon after the initial positive test. The annual cost of testing was approximately $62,000.Conclusions
Thrombophilia testing in the acute inpatient setting rarely impacted the clinical management of patients admitted with a stroke or TIA. By avoiding thrombophilia testing, both the potential for misdiagnosis and health care costs can be reduced. Therefore, we have discontinued thrombophilia testing in in-patients with a diagnosis of stroke. 相似文献16.

Background
Poststroke balance impairment adversely affects stroke outcomes and addressing the impairment is expected to constitute an important focus of neurorehabilitation.Aims
To examine the prevalence and factors associated with balance impairment after stroke.Methods
Ninety-five stroke survivors undergoing neurorehabilitation at 2 government hospitals in Northern Nigeria participated in this cross-sectional study. Berg Balance Scale (BBS) was used to assess the presence of balance impairment (BBS score of 0-20). Prevalence of balance impairment was presented as frequency and percentage while demographic and stroke-related determinants of balance impairments were identified using logistic regression analysis.Results
Thirty-five (36.8%) stroke survivors had balance impairment, and age, gender, and poststroke duration were statistically significant determinants. Stroke survivors aged less than 40 years (odds ratio [OR]?=?.14 [confidence interval [CI]?=?.20-.94]) and 40-59 years (OR?=?.23 [CI?=?.06-.81]) had a lower likelihood of having balance impairment compared to stroke survivors aged 60 years and above. Similarly, males had a lower likelihood of having balance impairment (OR?=?1.60 [CI?=?.05-.55]) compared to females while those in the acute/subacute phase of stroke had a 7-fold likelihood of having balance impairment (OR?=?7.74 [CI?=?2.63-22.79]) compared to those with chronic stroke.Conclusions
Poststroke balance impairment appears to be significantly influenced by stroke survivors’ age, gender, and poststroke duration. Hence, these variables should be considered when planning rehabilitation strategies for improving balance after stroke. 相似文献17.

Objectives
The angiotensin-converting enzyme 2 (ACE2) is closely associated with cardiovascular disease and cerebrovascular disease. Most studies on ACE2 gene polymorphism focused on its relations with cardiovascular disease, but there was a lack of research on its relations with stroke. Our study aimed to explore the association between 4 single-nucleotidepolymorphisms (SNPs) of ACE2 gene polymorphism and stroke recurrence.Design and Participants
In our study, the case group included 125 stroke patients with recurrence and the control group included 153 patients without recurrence. Four SNPs (rs2106809, rs2285666, rs879922, and rs2074192) were genotyped by Ligase detection reaction. The association between stroke recurrence and SNPs were analyzed by multivariate logistic regression.Results
We find no association between ACE2 gene polymorphism and stroke recurrence. Haplotype A-G-C may associate with the stoke recurrence of male patients. The recurrence risk of male stroke patients with hypertension history and rs2285666-C allele is 2.82 times as high as that of those without hypertension history but with T allele. Among male stroke patients with hypertension history, the recurrence risk of those with rs2285666-C allele is 2.38 times as high as those with T allele; and the recurrence risk of those with rs2106809-A allele is 2.12 times as high as those with G allele. But those recurrence risks lose their statistical significance after adjustment for other factors.Conclusions
We find no influence of ACE2 gene polymorphism on stroke recurrence and only find possible interaction between hypertension history and the ACE2 gene in male stroke patients. 相似文献18.

Background
Incidental findings on radiographic diagnostic imaging are a growing concern in the medical field. Little is known about the incidence and spectrum of incidental findings uncovered during stroke evaluations.Methods and Results
A random sample of 200 acute ischemic stroke admissions at an academic medical center was reviewed to better understand the incidence and spectrum of incidental findings on radiographic imaging studies obtained for a stroke evaluation. Among 200 stroke patients, 53 (26.5%) were found to have one or more incidental findings on radiographic imaging. Over 651 imaging studies, 69 incidental findings were uncovered, or 11 incidental findings per 100 imaging studies. Incidental findings were most commonly discovered within computerized tomography angiograms of the head and neck (n?=?41 from of 176 studies). The most commonly identified incidental findings included thyroid nodules (n?=?12), sinus disease (n?=?11), pulmonary nodules (n?=?10), and intracranial/cervical artery aneurysms (n?=?5).Conclusions
Incidental findings are commonly found in patients undergoing an evaluation for acute ischemic stroke, some of which may be clinically relevant. Vascular neurologists and other clinicians caring for stroke patients may benefit from guidance on the management of expected incidental findings. 相似文献19.

Background
The treatment of acute ischemic stroke due to large vessel occlusion (LVO) has revolutionized in the last decade. We sought to compile the most relevant literature published about the evolution in treating this disabling and fatal disease.Methods
A literature review of recent studies describing early treatment options like intravenous tissue plasminogen activator to the latest mechanical thrombectomy (MT) techniques was performed. We described in a chronological order the evolution of LVO treatment.Results
Recanalization rates with newer techniques and MT devices approach a 90% of effectiveness. Timely interventions have also resulted in better clinical outcomes with approximately 50% of patient achieving functional independence at 90 days. At least 14 new third generation thrombectomy devices are currently being evaluated in in vitro and clinical studies.Conclusions
The treatment of LVO with MT is feasible and safe. MT is standard of care in treating acute ischemic stroke due to LVO. 相似文献20.
