Morbimortality and determinants of reperfusion in ischemic stroke

SUMMARY BACKGROUND: Cerebrovascular accident (or stroke) and ischemic heart disease are the the major causes of death in the world. It is estimated that about 85% of strokes are ischemic in origin. Reperfusion therapy in the acute phase of ischemic stroke with a recombinant human tissue plasminogen activator is effective, but some factors influence the success of this treatment. OBJECTIVE: The aim of this study was to evaluate clinical aspects and possible determinants for reperfusion after venous thrombolysis. METHODS: This is a retrospective, cross-sectional, observational study based on a review of hospital records of inpatients diagnosed with ischemic stroke treated with intravenous thrombolysis, the main outcome being reperfusion or not. RESULTS: Data from this study revealed a predominance of females in the group of reperfused patients and males in the non-reperfused group, both maintaining moderate severity on the National Institutes of Health Stroke Scale and admission without statistical significance (p>0.18). In addition, the mean admission severity score was 13.2 for the group of reperfused patients and 14.2 for those not reperfused, and the mean ejection fraction of both groups was within normal functionality, with a mean of 0.50 for reperfused patients and 0.62 for non-reperfused patients. CONCLUSION: We found an association between successful venous chemical thrombolysis reperfusion and lower mortality in patients with acute stroke.

Disección carotídea espontánea: Presentación de un caso clínico con revisión de la literatura / Carotid Artery Dissection. Case Report and Literature Review

Resumen Introducción: La disección carotídea consiste en el desgarro de la pared del vaso. Es una patología infrecuente, pero es la causa más común de enfermedad vascular cerebral (EVC) isquémica en personas menores de 45 años. Las manifestaciones clínicas son muy variables. Método: Utilizamos las recomendaciones CARE para el reporte de casos clínicos. Caso clínico: Hombre de 45 años previamente sano, con debilidad aguda de la extremidad torácica derecha sin causa aparente. La tomografía simple de cráneo no evidenció alteraciones. La resonancia magnética mostró una oclusión completa de la arteria carótida interna en todos sus segmentos y disminución del flujo de la arteria cerebral media izquierda. La evolución clínica fue desfavorable. Conclusión: La disección carotídea debe sospecharse en personas con EVC sin factores de riesgo cardiovascular.

Abstract Introduction: Carotid dissection consists of a tear in the vessel wall. It is a rare pathology, but it is the most common cause of ischemic cerebral vascular disease (CVD) in people under 45 years of age. The clinical manifestations are very variable. Method: We used CARE recommendations for reporting clinical cases. Clinical case: Previously, a healthy 45-year-old man with acute weakness of the right thoracic extremity without apparent cause. The simple skull tomography did not show any alterations. MRI showed complete occlusion of the internal carotid artery in all its segments and decreased flow of the left middle cerebral artery. The clinical evolution was unfavorable. Conclusion: Carotid dissection should be suspected in people with CVD without cardiovascular risk factors.

Estimation of serum uric acid level in acute ischemic stroke

Background: The impact of uric acid as a stand-alone risk factor for non-communicable illness has been debated for decades. Strong free radical scavengers like hydroxyl ions, peroxynitrite, and other an?oxidants like ascorbic acid are all scavenged by serum uric acid. Neuroprotec?ve agents include uric acid and its connec?on to ischemic stroke is s?ll debatable. Therefore, the current study tried to evaluate the serum uric levels in acute ischemic stroke pa?ents. Methods: Pa?ents with acute stroke were included in the trial, thus if rTPA was given to them, it was noted. The pa?ent’s baseline blood pressure was taken (in a supine posi?on). All acute stroke pa?ents had blood drawn within 24 hours of admission to assess their lipid profiles, fas?ng blood sugar levels, and uric acid levels. A neurologist assessed each pa?ent, and computer tomography (CT) and magne?c resonance imaging were used to dis?nguish between ischemic stroke and other types of stroke (MRI). Results: Serum UA levels were found to be significantly higher in stroke pa?ents, with 77.5 percent of pa?ents having high levels (>6 mg/dL) compared to 30.0 percent of controls. When compared to the controls, the mean serum UA level in pa?ents was considerably higher (p=0.0212). Mul?ple logis?c regression analysis was used to determine the rela?onship between serum UA levels and outcome. Independent of other prognos?c criteria, pa?ents with high serum UA levels had a significantly worse outcome. Conclusion: A significant rela?onship exists between high serum UA levels and ischemic stroke, stroke subtypes (excluding lacunar stroke), and poor outcomes. Finding and managing modifiable risk factors for stroke has advanced quite a bit. Hyperuricemia could be therapeu?cally targeted in the same manner that other risk factors, such as dyslipidemia and blood pressure, are regularly treated a?er stroke.

Angioedema after rt-PA infusion led to airway emergency: a case report of rescue treatment with fresh frozen plasma

Abstract The authors report the case of a 71-year-old woman presented to the Emergency Department with acute ischemic stroke. She was treated with rt-PA and interventional endovascular revascularization and developed rapidly progressing angioedema that led to emergency intubation. The standard treatment was not very effective and the swelling improved after infusion of fresh frozen plasma. Angioedema after rt-PA infusion could be a life-threatening emergency that requires quick airway management by skilled professionals. As this condition is triggered by several factors, such as unregulated histamine and bradykinin production, the traditional treatment recommended by the guidelines may not be sufficient and the use of FFP can be considered as a safe and valuable aid.

Mediating effects of disease perception on disease uncertainty and health behaviors among thrombolysis therapy in patients with acute ischemic stroke / 中国实用护理杂志

Objective:To explore the mediating effects of disease perception on disease uncertainty and health behaviors among thrombolysis therapy in patients with acute ischemic stroke, to provide a theoretical basis for improving patient health behavior.Methods:By cross-sectional survey methods, from June 2021 to June 2022, a total of 123 thrombolysis therapy in patients with acute ischemic stroke were investigated by general information, Mishel Uncertainty in Illness Scale, Health Behavior Scale for Stroke Patients and Revised Illness Perception Questionnaire by convenience sampling method. The mediating effect of disease perception between disease uncertainty and health behavior was verified by structural equation model.Results:The scores of disease uncertainty, health behaviors and disease perception were (52.21 ± 7.67), (63.77 ± 9.40), (127.70 ± 26.19) points in patients with acute ischemic stroke. Health behaviors and each dimension including exercise, medication, instruction, nutrition, responsibility, tobacco and alcohol were negatively correlation between disease uncertainty ( r values were -0.762 to -0.411, all P<0.01), and positively correlation between disease perception ( r values were 0.689 to 0.912, all P<0.01). Disease uncertainty was a significantly negative predictor for health behaviors ( β= -0.71, P<0.01); disease perception was also a significantly negative predictor for disease perception ( β = -0.85, P<0.01). Disease uncertainty had a significantly indirect effect on the health behaviors for thrombolysis therapy in patients with acute ischemic stroke through disease perception, which showed the mediating effect of health behaviors accounts for 15.2% of total effect. Conclusions:Disease perception play a mediating role in the relationship between disease uncertainty and health behaviors among thrombolysis therapy in patients with acute ischemic stroke.

Systematic evaluation of pharmacoeconomic studies on acute ischemic stroke population in China / 中国药房

OBJECTIVE To systematically evaluate pharmacoeconomic studies （modeling approach） based on the Chinese acute ischemic stroke （AIS） population， and to provide the suggestions for improving the pharmacoeconomic evaluation method of AIS. METHODS Retrieved from CNKI， Wanfang Data Knowledge Service Platform， VIP， PubMed， Embase， the Cochrane Library， ScienceDirect， and Web of Science databases， relevant literature on pharmacoeconomic evaluation of AIS were collected from January 2014 to February 2022. Basic information of included study， basic information and outcome indicators of the model were analyzed statistically. The quality of the included literature was evaluated using CHEERS 2022， and problems in the existing literature were identified and suggestions were made. RESULTS Twelve papers were finally included， involving five in Chinese and seven in English. All studies reported the study perspective， mainly from the perspective of health system； the age of the target population was mainly distributed around 60 years old； the main interventions in the included studies were pharmacotherapy， including single-drug regimens and combination drug regimens； nine papers used decision trees combined with Markov models， and three papers used Markov models alone， but the classification of health status was inconsistent； all papers reported study time frame and cycle period， with most studies choosing a study time frame of 30 years and a cycle period of 1 year； all studies used modified Rankin scale scores as an indicator of clinical effectiveness， which were mainly derived from clinical trials； utility values in most literature were derived from published studies， and costs were mainly direct medical costs； all studies performed cost-utility analyses using quality-adjusted life years and/or incremental cost-effectiveness ratios as outcome indicators， and single-factor sensitivity analyses and probabilistic sensitivity analyses were performed， but no contextual analyses were conducted for the different model structures that may exist. CONCLUSIONS The overall report of the included studies is relatively complete， but the methodology is relatively uniform， and there are still deficiencies in terms of study perspective， study time frame， parameter sources， and contextual analysis. Future AIS pharmacoeconomic evaluations should further improve the report content in accordance with the CHEERS list entries， conduct contextual analysis of multiple health state classification approaches from a society-wide perspective， while using data from real- world sources and standardizing the uncertainty analysis process of the study results to increase the authenticity and reliability of the study results.

Research progress of thrombolytic drugs for acute ischemic stroke / 中国药房

Acute ischemic stroke is a cerebrovascular disease with high incidence， high mortality and disability， and high recurrence rate， which seriously endangers patients’ health. Thrombolytic drugs play a key role in the treatment of acute ischemic stroke by activating plasminogen， rapidly dissolving thrombi， reducing platelet aggregation， and achieving successful recanalization. In this study， we reviewed the principle of action of thrombolytic drugs， their classification and use on the basis of current research progress at home and abroad. The results show that the safety and efficacy of thrombolytic drugs have improved significantly from the first generation of thrombolytic drugs， streptokinase， which is not fibrin-specific， to the third generation of thrombolytic drugs， tenecteplase， which not only retain the characteristics of directly activating plasminogen， but also enhance the specificity of fibrin and prolong the half-life. With the development of research， small-molecular compounds with the inhibition of plasminogen activator， or the modification of thrombolytic drugs with strong anti-plasminogen activator inhibition activity in vivo， or the search for new small-molecular substances with thrombolytic effect from microorganisms and natural plants， have become the focus of research on new thrombolytic drugs. The new thrombolytic drugs are likely to replace the current thrombolytic drugs because of greater thrombolytic efficacy and fewer side effects.

Influencing factors of early activity in patients with acute ischemic stroke based on social ecological model: A qualitative study / 中南大学学报(医学版)

OBJECTIVES@#Acute ischemic stroke (AIS) is one of the main causes of disability in middle-aged and elderly people, and early activity plays an important role in functional recovery. This study aims to understand the factors that affect the implementation of early activity in patients with AIS and to provide reference for promoting early activity implementation and developing intervention strategies for AIS patients.@*METHODS@#Using purposive sampling, 19 AIS patients and their caregivers who visited at Stroke Center in the Third Xiangya Hospital of Central South University and the Third Hospital of Changsha from June to December 2021, as well as 19 medical staff, hospital administrators, or community workers providing medical health services to stroke patients, were selected as interviewes. A semi-structured interview was conducted based on the social ecological theory model, and the Colaizzi seven-step method was used to analyze the interview data.@*RESULTS@#According to qualitative interview results, the factors affecting early activity in AIS patients were summarized into 4 themes and 12 sub-themes: medical staff factors (insufficient knowledge and skills, insufficient knowledge of early activity, unclear division of responsibilities), patient factors (severity of the disease, lack of knowledge, psychological pressure, fear of falling), social environmental factors (lack of social support, shortage of human resources and rehabilitation equipment, insufficient medical insurance support), and evidence and norms (the evidence for early activity needs improvement, lack of standardized early activity procedures).@*CONCLUSIONS@#Early activity in AIS patients is impacted by factors at multiple levels, including medical staff, patients, social environment, and evidence and norms. Developing comprehensive intervention strategies to address these factors can promote early activity implementation in AIS patients.

Longitudinal change of six common inflammatory cytokines and their relationship to anxiety, depression, and cognitive impairment in acute ischemic stroke patients

Inflammatory cytokines are known to be involved in acute ischemic stroke (AIS), while the relationship of multiple inflammatory cytokines with mental disorders in AIS is less reported. This research intended to explore the longitudinal variation of common inflammatory cytokines and their correlation with anxiety, depression, and cognitive impairment in AIS patients. Six inflammatory cytokines were detected by enzyme-linked immunosorbent assay among 175 AIS patients at admission (baseline) and on the day (D)1, D3, and D7 after admission. Anxiety, depression, and cognition were evaluated using the Hospital Anxiety and Depression Scale and Mini-Mental State Examination at discharge, respectively. Anxiety, depression, and cognitive impairment rates were 32.6, 39.4, and 19.4%, respectively. Tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-8, and IL-17A increased from baseline to D1, then decreased from D1 to D7 (all P<0.001), while IL-10 presented an opposite trend (P<0.001). Interestingly, TNF-α on D1 and D3, IL-6 on D3, IL-8 on D3 and D7, and IL-17A on D1, D3, and D7 correlated with higher anxiety rate (all P<0.05). TNF-α on D1, D3, and D7, IL-8 at baseline, D1, D3, and D7, IL-17A on D1 and D7 correlated with increased depression rate (all P<0.05). In addition, IL-1β on D1 and IL-17 at baseline, D1, D3, and D7 correlated with elevated cognitive-impairment rate (all P<0.05). Inflammatory cytokines were dysregulated after disease onset, and their longitudinal change correlated with psychological issues in AIS patients.

Contact aspiration and stent retriever versus stent retriever alone following mechanical thrombectomy for patients of acute ischemic stroke: A recanalization success analysis

Abstract Objective Second-generation catheters used in mechanical thrombectomy have different advantages and disadvantages. The objective of this study was to evaluate the effectiveness and safety of the combination of contact aspiration and stent retriever technique on the rate of reperfusion after mechanical thrombectomy for large vessel occlusion. Methods Patients who underwent contact aspiration alone (CAA cohort, n = 150), stent retriever alone (SRA cohort, n = 129), or combined contact aspiration and stent retriever (CSR cohort, n = 122) techniques following mechanical thrombectomy were included in the analysis. A balloon guide catheter was used for all thrombectomies. Digital subtraction angiography was used to identify thrombolysis in cerebral infarction. Results The number of patients with thrombolysis in cerebral infarction score of ≥ 2c (near complete or complete antegrade reperfusion) was significantly higher in the CSR cohort than those in the CAA cohort (101 [83%] vs. 90 [60%], p < 0.0001) and those of SRA cohort (101 [83%] vs. 77 [59%], p = 0.0001). Arterial perforation was higher in patients in the CSR cohort than in those in the CAA (p < 0.0001) and SRA (p = 0.015) cohorts. Intracerebral hemorrhage was lower in patients in the CSR cohort than in those in the CAA (p = 0.0001) and SRA (p = 0.0353) cohorts. All-cause mortality at 1 year was fewer in the CSR cohort than in the CAA cohort (p = 0.018). Conclusions The combination of thrombo aspiration by large bore aspiration catheter and stent retriever is the most effective technique but has some related risks. Level of evidence IV. Technical efficacy stage 1.

Eficacia de tenecteplase comparada con alteplase para tratamiento de ictus isquémico agudo. Una revisión narrativa

Introducción: La trombólisis intravenosa con Alteplase (ALT) se recomienda como tratamiento estándar siendo el único agente trombolítico aprobado por la FDA, en infarto cerebral. La Tenecteplase (TNK), un activador tisular del plasminógeno modificado, surge como agente antitrombótico alternativo. Esta revisión narrativa evalúa la evidencia actual y aborda los problemas prácticos sobre la eficacia y seguridad de tenecteplase en comparación con alteplase. Metodología: Se realizó una búsqueda sistemática y analítica de la literatura, y se proporcionó una síntesis cualitativa de metaanálisis y ensayos clínicos concluidos, que compararon la efectividad y seguridad de la tenecteplase con alteplase en el AIS, utilizando artículos indexados en MEDLINE, Cochrane Library y Scopus. Resultados: Los ensayos clínicos aleatorizados en su mayoría coinciden al encontrar que TNK es al menos tan o más efectiva que la ALT para mejoría neurológica después del AIS; mientras los metaanálisis coinciden en que los pacientes que recibieron TNK presentaron una mayor recanalización exitosa, pero difieren en cuanto a los hallazgos de mejoría neurológica temprana, resultado funcional a los 90 días y mortalidad a los 90 días. Conclusión: La tenecteplase es al menos tan eficaz como la Alteplase con respecto a la mejoría neurológica después del tratamiento del accidente cerebrovascular isquémico agudo.

Introduction: Intravenous thrombolysis with alteplase (ALT) is recommended as standard treatment, being the only thrombolytic agent approved by the FDA. Tenecteplase (TNK), a modified tissue plasminogen activator, is emerging as an alternative antithrombotic agent. This narrative review assesses the current evidence and addresses practical issues regarding the efficacy and safety of tenecteplase compared to alteplase. Methodology: A systematic and analytical search of the literature was performed, providing a qualitative synthesis of meta-analyses and completed clinical trials comparing the effectiveness and safety of tenecteplase with alteplase in AIS, using articles indexed in MEDLINE, the Cochrane Library, and Scopus. Results: Randomized clinical trials mostly agree in finding TNK to be at least as or more effective than ALT for neurological improvement after AIS; while the meta-analyses agree that patients who received TNK had more successful recanalization, they differ in terms of the findings of early neurological improvement, functional outcome at 90 days, and mortality at 90 days. Conclusion: Tenecteplase is at least as effective as alteplase with regard to neurological improvement after treatment of acute ischemic stroke.

Associations between insomnia and large vessel occlusion acute ischemic stroke: An observational study

Abstract Objectives: This study explored the association between insomnia and the clinical outcome of large vessel occlusion Acute Ischemic Stroke (AIS) and attempted to explore its potential mechanisms from the perspectives of inflammation and oxidative stress. Methods: AIS patients who underwent endovascular treatment for large vessel occlusion at Binzhou Central Hospital from 2018 to 2022 (n = 508) were included. Patients were divided into an insomnia group and a non-insomnia group. Insomnia was judged by self-reported Athens Insomnia Scale score. Regression analysis was used to compare the differences in the 24-hour and 7-day National Institutes of Health Stroke Scale (NIHSS) score, Early Neurological Deterioration (END), early adverse event incidence, 90-day prognosis and mortality, and serum bio-markers levels. Results: The incidence of insomnia in the study population was 39.6% (n = 144, insomnia group; n = 364, non-insomnia group). Compared with the non-insomnia group, a worse prognosis outcome (63% vs. 49%, adjusted rate ratio: 1.8, 95% Confidence Interval: 1.2-3.7; p = 0.016), higher 24-h and 7-day NIHSS score (17 [9-36] vs. 13 [5-20]; p = 0.024, and 11 [4‒24) vs. 8 [2‒14]; p = 0.031, respectively), higher END (24% vs. 15%, p = 0.022), and higher incidence of adverse events were observed in the insomnia group (79% vs. 59%, p = 0.010). The 90-day mortality was higher in the insomnia group than that in the non-insomnia group (22% vs. 17%), however, such a difference was not statistically significant. Conclusion: Insomnia is closely related to the clinical outcome of AIS with large vessel occlusion, and inflammation and oxidative stress mechanisms may be involved.

National Institute of Health Stroke Scale was associated with the immediate and long-term prognosis of patients with acute ischemic stroke treated with intravenous thrombolysis

OBJECTIVE: The objective of this study was to examine whether the National Institute of Health Stroke Scale was associated with the short- and long-term prognosis of patients with acute ischemic stroke treated with intravenous thrombolysis. METHODS: A total of 247 patients with acute ischemic stroke admitted to the hospital from April 2019 to October 2020 were retrospectively selected as study subjects, and the immediate and long-term prognosis after thrombolysis was assessed using the modified Rankin Scale and divided into good prognosis group (119 cases) and poor prognosis group (128 cases) based on the effect of thrombolysis. Both groups were treated with alteplase, the National Institute of Health Stroke Scale of the two groups was compared, and the factors affecting the prognosis of acute ischemic stroke were analyzed. RESULTS: After intravenous thrombolysis, 24 h, and 7 days of treatment, the National Institute of Health Stroke Scale in the poor prognosis group was higher than those of patients in the good prognosis group, and the differences were statistically significant (p<0.05). The results of the multivariate analysis suggested that National Institute of Health Stroke Scale before treatment was an independent factor associated with the 3-month (OR: 1.068, 95%CI 1.015-1.123, p=0.011) and long-term poor prognosis (OR: 1.064, 95%CI 1.012-1.119, p=0.015) in patients with acute ischemic stroke receiving intravenous thrombolysis after adjustment of age, gender, body mass index, smoking, alcohol consumer, onset-to-door time, door-to-needle time, and imaging score. CONCLUSION: The National Institute of Health Stroke Scale could be a promising indicator for the prognosis, and active intervention is needed to improve the quality of life in patients with acute ischemic stroke.

Effects of acupuncture on neurologic function and serum inflammatory factors after thrombolysis in acute ischemic stroke / 中国针灸

OBJECTIVE@#To observe the effects of acupuncture on neurologic function and serum inflammatory factors in patients after thrombolysis in acute ischemic stroke (AIS).@*METHODS@#A total of 102 AIS patients with onset to treatment time (OTT) ≤3 h were randomly divided into an observation group and a control group, 51 cases each group. In the control group, thrombolysis and conventional medical treatment were applied. On the basis of the treatment as the control group, acupuncture at Shuigou (GV 26), Zhongwan (CV 12), Qihai (CV 6), Neiguan (PC 6), etc. was applied in the observation group, 30 min each time, once a day. Both groups were treated for 2 weeks. Before and after treatment, the scores of National Institutes of Health stroke scale (NIHSS), modified Rankin scale (mRS), modified Barthel index (MBI) and serum level of homocysteine (Hcy), hypersensitive C-reactive protein (hs-CRP) were compared, and the clinical efficacy was evaluated in the two groups.@*RESULTS@#After treatment, the scores of NIHSS, mRS and serum level of Hcy, hs-CRP were decreased compared with those before treatment (P<0.05), while the MBI scores were increased (P<0.05) in the two groups. The scores of NIHSS, mRS and serum level of Hcy, hs-CRP in the observation group were lower than those in the control group (P<0.05, P<0.01), the MBI score in the observation group was higher than that in the control group (P<0.01). The total effective rate was 88.2% (45/51) in the observation group, which was superior to 70.6% (36/51) in the control group (P<0.05).@*CONCLUSION@#Acupuncture could promote the recovery of neurologic function in patients after thrombolysis in AIS, improve the ability of daily living, which may be related to reducing the level of inflammatory factors, thus inhibiting inflammatory response and improving cerebral ischemia reperfusion injury.

Efficacy and safety of tenecteplase in the treatment of acute ischemic stroke：a meta-analysis / 中国药房

OBJECTIVE To systematically evaluate the efficacy and safety of intravenous bolus of tenecteplase in the treatment of acute ischemic stroke （AIS）， in order to provide evidence-based support for the clinic’s choice of intravenous thrombolytic drugs. METHODS Randomized controlled trials （RCTs） about the efficacy and safety of tenecteplase versus alteplase （control） in the treatment of AIS were collected from PubMed， Embase， the Cochrane Library， Web of Science， Sinomed， CNKI， Wanfang Data， and VIP during the inception to June 2022. Two evaluators independently screened the literature， extracted data from the literature， assessed the bias risk of included study， and then conduct meta-analysis by using Stata 15 software. RESULTS A total of 8 literature were included， involving 2 129 patients. Meta-analysis results showed that the early improvement rate of neurological function [OR（95%CI）＝2.44（1.09，5.46），P＝0.030] and the good rate of neurological function recovery （modified Rankin scale score 0-2 after 90 days of intravenous thrombolysis treatment） [OR（95%CI）＝1.54（1.00，2.36），P＝0.048] were higher in 0.25 mg/kg tenecteplase group （medium dose） than alteplase group. According to meta-analysis of other outcome indicators （including recanalization rate， percentage of reperfusion lesions， excellent rate of neurological function recovery， the incidence rate of bleeding， the incidence rate of symptomatic intraventricular hemorrhage and all-cause mortality rate within 90 d）， the tenecteplase group had no statistically significant difference with alteplase group （P＞0.05）. CONCLUSIONS Compared with alteplase， medium dose of tenecteplase has some advantages in terms of early neurological function improvement and neurological function recovery， and it does not increase the risk of adverse events.

Risk factors of stroke-associated pneumonia for patients with mild to moderate acute ischemic stroke / 中国康复理论与实践

ObjectiveTo explore the risk factors of stroke-associated pneumonia (SAP) for patients with mild to moderate acute ischemic stroke (AIS). MethodsFrom October, 2016 to December, 2019, 321 patients with mild to moderate AIS in Beijing Bo'ai Hospital were collected and divided into SAP group (n = 71) and non-SAP group (n = 250) according to whether they were complicated with SAP. Gender, age, time from symptom onset to admission, systolic pressure, diastolic pressure, scores of National Institutes of Health Stroke Scale (NIHSS) at admission, and medical history were recorded. Laboratory indexes including the count of white blood cell and platelet, levels of D-dimer, hypersensitive C-reactive protein (hs-CRP) and α-hydroxybutyrate dehydrogenase (α-HBDH) were measured. ResultsUnivariate analysis showed that age, NIHSS score, history of hypertension, atrial fibrillation, prior cerebral infarction, the count of white blood cell and platelet, the levels of D-dimer, hs-CRP and α-HBDH were the influencing factors of SAP (P < 0.2). Multivariate Logistic regression showed that age > 70 years old (OR = 7.121, 95%CI 3.493 to 14.514, P < 0.001), NIHSS score > 4 (5 to 10, OR = 4.861, 95% CI 2.412 to 9.797, P < 0.001), the count of platelet > 300×109/L (OR = 6.978, 95% CI 1.864 to 26.128, P = 0.004), and the level of D-dimer > 1.0 mg/L (OR = 3.036, 95% CI, 1.518 to 6.071, P = 0.002) were the risk factors of SAP. The model fitted the original data well (HL = 1.509，P = 0.680) and appeared a good prediction (AUC = 0.847, 95% CI 0.796 to 0.898, P < 0.001). ConclusionAge > 70 years old, NIHSS score > 4 (5 to 10), the count of platelet > 300×109/L and the level of D-dimer > 1.0 mg/L were the risk factors of SAP for patients with mild to moderate AIS.

Association of serum adiponectin and high sensitivity C-reactive protein levels to short-term outcome in patients with acute ischemic stroke / 中国康复理论与实践

ObjectiveTo study the association of serum adiponectin and high sensitivity C-reactive protein (hs-CRP) levels to short-term outcome in patients with acute ischemic stroke (AIS). MethodsClinical data of 216 patients with AIS in Beijing Bo'ai Hospital from January, 2019 to September, 2020 were collected. The serum biochemical indicator was measured in all the patients within 24 hours after enrollment, and adiponectin was detected with enzyme-linked immunosorbent assay. Meanwhile, all patients were evaluated with National Institute of Health Stroke Scale (NIHSS). Modified Rankin Scale (mRS) was used to assess the functional outcome 90 days after onset during follow-up. ResultsThe incidence of poor outcome in patients with AIS within 90 days was 48.1%. Compared with the good outcome group, the serum adiponectin was lower (t = 5.861, P < 0.001) and the serum hs-CRP level was higher (Z = 5.525, P < 0.001) poor outcome group. Reduced serum adiponectin (OR = 0.862, 95%CI 0.751 to 0.975, P < 0.001) and increased serum hs-CRP (OR = 1.215, 95%CI 1.015 to 1.455, P < 0.001) were independent risk factors for poor outcome in patients with AIS. The areas under curve (95% CI) of serum adiponectin and hs-CRP for predicting the outcome of patients with AIS were 0.819 (0.761 to 0.877) and 0.722 (0.654 to 0.791), respectively (P < 0.001). The predictive power of serum adiponectin was higher than that of hs-CRP (Z = 2.151, P = 0.032). The optimum cut-off point of adiponectin was < 3.5 mg/L, and the Yoden index was 0.609, yielding a sensitivity of 0.704 and a specificity of 0.905. ConclusionSerum adiponectin and hs-CRP can serve as independent predictors for short functional outcome in patients with AIS.

Evaluation of cardiac-electrophysiological balance according to National Institutes of Health Stroke Scale score at admission and discharge in acute ischemic stroke patients: A pilot study

SUMMARY OBJECTIVE: The main objectives of this investigation were to determine whether there were any relationships between corrected cardiac-electrophysiological balance value and National Institutes of Health Stroke Scale scores at admission and discharge in patients with acute ischemic stroke and to assess whether cardiac-electrophysiological balance value was an independent predictor of high National Institutes of Health Stroke Scale scores (National Institutes of Health Stroke Scale score ≥5). METHODS: In this retrospective and observational study, 231 consecutive adult patients with acute ischemic stroke were evaluated. The cardiac-electrophysiological balance value was obtained by dividing the corrected QT interval by the QRS duration measured from surface electrocardiography. An experienced neurologist used the National Institutes of Health Stroke Scale score to determine the severity of the stroke at the time of admission and before discharge from the neurology care unit. The participants in the study were categorized into two groups: those with minor acute ischemic stroke (National Institutes of Health Stroke Scale score=1-4) and those with moderate-to-severe acute ischemic stroke (National Institutes of Health Stroke Scale scores ≥5). RESULTS: Acute ischemic stroke patients with National Institutes of Health Stroke Scale score ≥5 had higher heart rate, QT, corrected QT interval, T-peak to T-end corrected QT interval, cardiac-electrophysiological balance, and cardiac-electrophysiological balance values compared with those with an National Institutes of Health Stroke Scale score of 1-4. The cardiac-electrophysiological balance value was shown to be independently related to National Institutes of Health Stroke Scale scores ≥5 (OR 1.102, 95%CI 1.036-1.172, p<0.001). There was a moderate correlation between cardiac-electrophysiological balance and National Institutes of Health Stroke Scale scores at admission (r=0.333, p<0.001) and discharge (r=0.329, p<0.001). CONCLUSIONS: The findings of this study demonstrated that the cardiac-electrophysiological balance value was related to National Institutes of Health Stroke Scale scores at admission and discharge. Furthermore, an elevated cardiac-electrophysiological balance value was found to be an independent predictor of National Institutes of Health Stroke Scale score ≥5.

Clinical characteristics and related risk factors of acute ischemic stroke complicated with cerebral cardiac syndrome / 中华急诊医学杂志

Objective:To investigate the clinical characteristics and risk factors of acute ischemic stroke (AIS) complicated with cerebral cardiac syndrome (CCS).Methods:The clinical data of AIS patients admitted to the ICU of our hospital from January 2019 to May 2021 were collected and retrospectively analyzed. According to whether CCS occured after stroke, the patients were divided into the CCS group and control group. Binary logistic regression analysis was used to analyze the clinical characteristics of AIS combined with CCS and the risk factors for the occurrence of CCS.Results:A total of 196 patients with AIS were included, and 92 patients had CCS, of which 74 occurred within 72 h after AIS. Binary logistic regression analysis showed that old age ( OR=1.15, 95% CI: 1.01-1.23), hypertension ( OR=1.41, 95% CI: 1.26-1.58), diabetes ( OR=2.05, 95% CI: 1.86-2.24), chronic kidney disease ( OR=1.36, 95% CI: 1.22-1.48), chronic obstructive pulmonary disease ( OR=1.46, 95% CI:1.22-2.48), smoking ( OR=1.52, 95% CI:1.23-1.78), higher NISSH score ( OR=1.36, 95% CI: 1.29-1.48), brainstem infarction ( OR=2.33, 95% CI: 2.21-2.50), thalamic infarction ( OR=1.21, 95% CI: 1.17-1.28), and hyperlipidemia ( OR=1.86, 95% CI: 1.61-1.96) were associated with the occurrence of CCS after stroke. Conclusions:CCS is a common complication in patients with AIS, and mostly occurs within 72 hours after stroke. The risk of CCS is not only related to the history of hypertension, diabetes, chronic kidney disease, smoking history and hyperlipidemia, but also related to the location of infarction and the degree of nerve function injury. The changes of cardiac function in patients with AIS should be closely monitored to prevent cardiac events.
