ABSTRACT Introduction: Ischemic stroke is treated with thrombolytic therapy, applied even in the acute phase, promoting a significant improvement in the after-effects caused by this condition. Considering the complexity of thrombolytic therapy, it is necessary for nurses to understand the skills required to assist in care. Objective: To identify scientific evidence about the competencies of nurses in the care of patients with stroke who are eligible for thrombolytic therapy. Methodology: An integrative review consisting of six stages (elaboration of the question, literature review, data collection, analysis, discussion, and presentation), conducted in MEDLINE, LILACS, BDENF, IBECS, PubMed, Scopus, Web of Science, Embase, and CINAHL databases. The search was carried out between August and September 2022 using primary studies as the inclusion criteria: free of charge, fully available electronically, published in English, Portuguese, or Spanish. Initially, 2.830 studies were obtained, which underwent a selection process that included only those studies that met the previously established criteria. Results: Based on the twelve studies included in this review, competencies focused on three care activities were identified: care management such as teamwork; codes; flows and protocols; patient care before, during, and after the use of thrombolytic therapy; and education health education for staff, patients, and families. Conclusion: The findings of this review highlighted the nurses' competencies in the care of patients eligible for thrombolytic therapy, which encompass different areas of the nurse's work. For this study, assistance competencies prevailed, followed by management competencies.

RESUMEN

RATIONALE: Marfan syndrome (MFS), which is a dominantly inherited connective tissue disease resulting from a mutation in the FBN1 gene, exhibits variable manifestations affecting the cardiovascular, musculoskeletal, ophthalmologic, and pulmonary systems. Notably, neurologic deficiency, which involves ischemic or hemorrhagic stroke, is a rare but severe manifestation. The safety of rt-PA treatment for ischemic stroke caused by MFS is still under discussion. PATIENT CONCERNS: In the current report, we discuss 3 atypical MFS cases presented as acute ischemic stroke, compared to those exhibiting cardiovascular and musculoskeletal abnormalities. DIAGNOSES: Three patients were diagnosed with acute ischemic stroke accompanied by MFS based on clinical manifestations, imaging examinations, and genetic testings. INTERVENTIONS: The first case underwent intravenous thrombolytic therapy with rt-PA, the second case received antiplatelet therapy, and the third case received anticoagulant therapy and perfusion therapy. OUTCOMES: The neurologic deficiency of all three patients showed improvement upon discharge, and there were no symptoms of recurrence observed during the follow-up period. LESSONS SUBSECTIONS: MFS is a rare etiology in young people with embolic stroke of undetermined source. Physicians should take MFS into consideration when they observe the characteristic symptoms during a consultation. The potential pathogenesis of ischemic stroke secondary to MFS may include cardio-embolism, arterial dissection, and hypoperfusion. Although intravenous thrombolysis is a promising therapy to treat acute ischemic stroke, further examinations should be conducted to rule out contraindications in patients with a suspicion of MFS.

RESUMEN

AIMS: To investigate the characteristics of dynamic cerebral autoregulation (dCA) after intravenous thrombolysis (IVT) and assess the relationship between dCA and prognosis. METHODS: Patients with unilateral acute ischemic stroke receiving IVT were prospectively enrolled; those who did not were selected as controls. All patients underwent dCA measurements, by quantifying the phase difference (PD) and gain, at 1-3 and 7-10 days after stroke onset. Simultaneously, two dCA-based nomogram models were established to verify the predictive value of dCA for patients with mild-to-moderate stroke. RESULTS: Finally, 202 patients who received IVT and 238 who did not were included. IVT was positively correlated with higher PD on days 1-3 and 7-10 after stroke onset. PD values in both sides at 1-3 days after stroke onset and in the affected side at 7-10 days after onset were independent predictors of unfavorable outcomes in patients who received IVT. Additionally, in patients with mild-to-moderate stroke who received IVT, the dCA-based nomogram models significantly improved the risk predictive ability for 3-month unfavorable outcomes. CONCLUSION: IVT has a positive effect on dCA in patients with acute stroke; furthermore, dCA may be useful to predict the prognosis of patients with IVT.

RESUMEN

INTRODUCTION: The risk of major bleeding complications in catheter directed thrombolysis (CDT) for acute limb ischemia (ALI) remains high, with reported major bleeding complication rates in up to 1 in every 10 treated patients. Fibrinogen was the only predictive marker used for bleeding complications in CDT, despite the lack of high quality evidence to support this. Therefore, recent international guidelines recommend against the use of fibrinogen during CDT. However, no alternative biomarkers exist to effectively predict CDT-related bleeding complications. The aim of the POCHET biobank is to prospectively assess the rate and etiology of bleeding complications during CDT and to provide a biobank of blood samples to investigate potential novel biomarkers to predict bleeding complications during CDT. METHODS: The POCHET biobank is a multicentre prospective biobank. After informed consent, all consecutive patients with lower extremity ALI eligible for CDT are included. All patients are treated according to a predefined standard operating procedure which is aligned in all participating centres. Baseline and follow-up data are collected. Prior to CDT and subsequently every six hours, venous blood samples are obtained and stored in the biobank for future analyses. The primary outcome is the occurrence of non-access related major bleeding complications, which is assessed by an independent adjudication committee. Secondary outcomes are non-major bleeding complications and other CDT related complications. Proposed biomarkers to be investigated include fibrinogen, to end the debate on its usefulness, anti-plasmin and D-Dimer. DISCUSSION AND CONCLUSION: The POCHET biobank provides contemporary data and outcomes of patients during CDT for ALI, coupled with their blood samples taken prior and during CDT. Thereby, the POCHET biobank is a real world monitor on biomarkers during CDT, supporting a broad spectrum of future research for the identification of patients at high risk for bleeding complications during CDT and to identify new biomarkers to enhance safety in CDT treatment.

RESUMEN

BACKGROUND: Early reperfusion therapy is acknowledged as the most effective approach for reducing case fatality rates in patients with ST-segment elevation myocardial infarction (STEMI). OBJECTIVE: Estimate the clinical and economic consequences of delaying reperfusion in patients with STEMI. METHODS: This retrospective cohort study evaluated mortality rates and the total expenses incurred by delaying reperfusion therapy among 2622 individuals with STEMI. Costs of in-hospital care and lost productivity due to death or disability were estimated from the perspective of the Brazilian Unified Health System indexed in international dollars (Int$) adjusted by purchase power parity. A p < 0.05 was considered statistically significant. RESULTS: Each additional hour of delay in reperfusion therapy was associated with a 6.2% increase (95% CI: 0.3% to 11.8%, p = 0.032) in the risk of in-hospital mortality. The overall expenses were 45% higher among individuals who received treatment after 9 hours compared to those who were treated within the first 3 hours, primarily driven by in-hospital costs (p = 0.005). A multivariate linear regression model indicated that for every 3-hour delay in thrombolysis, there was an increase in in-hospital costs of Int$497 ± 286 (p = 0.003). CONCLUSIONS: The findings of our study offer further evidence that emphasizes the crucial role of prompt reperfusion therapy in saving lives and preserving public health resources. These results underscore the urgent need for implementing a network to manage STEMI cases.


FUNDAMENTO: A terapia de reperfusão precoce é reconhecida como a abordagem mais eficaz para reduzir as taxas de letalidade de casos em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST). OBJETIVO: Estimar as consequências clínicas e econômicas do atraso da reperfusão em pacientes com IAMCSST. MÉTODOS: O presente estudo de coorte retrospectivo avaliou as taxas de mortalidade e as despesas totais decorrentes do atraso na terapia de reperfusão em 2.622 indivíduos com IAMCSST. Os custos de cuidados hospitalares e perda de produtividade por morte ou incapacidade foram estimados sob a perspectiva do Sistema Único de Saúde indexado em dólares internacionais (Int$) ajustados pela paridade do poder de compra. Foi considerado estatisticamente significativo p < 0,05. RESULTADOS: Cada hora adicional de atraso na terapia de reperfusão foi associada a um aumento de 6,2% (intervalo de confiança de 95%: 0,3% a 11,8%, p = 0,032) no risco de mortalidade hospitalar. As despesas gerais foram 45% maiores entre os indivíduos que receberam tratamento após 9 horas em comparação com aqueles que foram tratados nas primeiras 3 horas, impulsionados principalmente pelos custos hospitalares (p = 0,005). Um modelo de regressão linear multivariada indicou que para cada 3 horas de atraso na trombólise, houve um aumento nos custos hospitalares de Int$ 497 ± 286 (p = 0,003). CONCLUSÕES: Os achados do nosso estudo oferecem mais evidências que enfatizam o papel crucial da terapia de reperfusão imediata no salvamento de vidas e na preservação dos recursos de saúde pública. Estes resultados enfatizam a necessidade urgente de implementação de uma rede para gerir casos de IAMCSST.

RESUMEN

BACKGROUND: The use of thrombectomy in patients with acute stroke and a large infarct of unrestricted size has not been well studied. METHODS: We assigned, in a 1:1 ratio, patients with proximal cerebral vessel occlusion in the anterior circulation and a large infarct (as defined by an Alberta Stroke Program Early Computed Tomographic Score of ≤5; values range from 0 to 10) detected on magnetic resonance imaging or computed tomography within 6.5 hours after symptom onset to undergo endovascular thrombectomy and receive medical care (thrombectomy group) or to receive medical care alone (control group). The primary outcome was the score on the modified Rankin scale at 90 days (scores range from 0 to 6, with higher scores indicating greater disability). The primary safety outcome was death from any cause at 90 days, and an ancillary safety outcome was symptomatic intracerebral hemorrhage. RESULTS: A total of 333 patients were assigned to either the thrombectomy group (166 patients) or the control group (167 patients); 9 were excluded from the analysis because of consent withdrawal or legal reasons. The trial was stopped early because results of similar trials favored thrombectomy. Approximately 35% of the patients received thrombolysis therapy. The median modified Rankin scale score at 90 days was 4 in the thrombectomy group and 6 in the control group (generalized odds ratio, 1.63; 95% confidence interval [CI], 1.29 to 2.06; P<0.001). Death from any cause at 90 days occurred in 36.1% of the patients in the thrombectomy group and in 55.5% of those in the control group (adjusted relative risk, 0.65; 95% CI, 0.50 to 0.84), and the percentage of patients with symptomatic intracerebral hemorrhage was 9.6% and 5.7%, respectively (adjusted relative risk, 1.73; 95% CI, 0.78 to 4.68). Eleven procedure-related complications occurred in the thrombectomy group. CONCLUSIONS: In patients with acute stroke and a large infarct of unrestricted size, thrombectomy plus medical care resulted in better functional outcomes and lower mortality than medical care alone but led to a higher incidence of symptomatic intracerebral hemorrhage.

RESUMEN

Thromboembolism and related complications are a leading cause of morbidity and mortality worldwide and various assays have been developed to test thrombolytic drug efficiency both in vitro and in vivo. There is increasing demand for more physiologically relevant in-vitro clot models for drug development due to the complexity and cost associated with animal models in addition to their often lack of translatability to human physiology. Flow, pressure, and shear rate are important characteristics of the circulatory system, with clots that are formed under flow displaying different morphology and digestion characteristics than statically formed clots. These factors are often unrepresented in conventional in-vitro clot digestion assays, which can have pharmacological implications that impact drug translational success rates. The Real-Time Fluorometric Flowing Fibrinolysis (RT-FluFF) assay was developed as a high-fidelity thrombolysis testing platform that uses fluorescently tagged clots formed under shear flow, which are then digested using circulating plasma in the presence or absence of fibrinolytic pharmaceutical agents. Modifying the flow rates of both clot formation and clot digestion steps allows the system to imitate arterial, pulmonary, and venous conditions across highly diverse experimental setups. Measurements can be taken continuously using an in-line fluorometer or by taking discrete time points, as well as a conventional end point clot mass measurement. The RT-FluFF assay is a flexible system that allows for the real-time tracking of clot digestion under flow conditions that more accurately represent in-vivo physiological conditions while retaining the control and reproducibility of an in-vitro testing system.

RESUMEN

Data comparing catheter-based thrombectomy (CBT) and catheter-directed thrombolysis (CDT) in acute pulmonary embolism are lacking. To address this, we performed a meta-analysis of prospective and retrospective studies of CBT and compared it to performance goal rates of mortality and major bleeding from a recently published network meta-analysis. When compared with performance goal for CDT based on historical studies, CBT was noninferior for all-cause mortality (6.0% vs 6.87%; P-valueNI < .001), non-inferior and superior for major bleeding (4.9% vs 11%; P-valueNI < .001 and P < .001 for superiority).

RESUMEN

BACKGROUND: Acute cerebral infarction (ACI) is a common neurological disease that is associated with high morbidity, disability and mortality rates. At present, antiplatelet therapy is a necessary treatment for ACI. The present study aimed to investigate the effects of omentin-1 on the intravenous thrombolysis of ACI. OBJECTIVE: The present study aimed to investigate the effects of omentin-1 on the intravenous thrombolysis of ACI. MATERIAL AND METHODS: The mouse model of ACI was induced using male C57BL/6 mice through middle cerebral artery occlusion (MCAO). Meanwhile, the murine BV2 microglial cells were pretreated with 0.1 mg/ml of lipopolysaccharide (LPS), and then induced with 2 mM of adenosine triphosphate (ATP). RESULTS: The omentin-1 mRNA expression in patients receiving intravenous thrombolysis for ACI was down-regulated compared with the normal group. Additionally, the serum level of omentin-1 was negatively correlated with National Institute of Health Stroke Scale (NIHSS) score or serum level of IL-1ß or MMP-2 in patients receiving intravenous thrombolysis for ACI. Meanwhile, the serum mRNA expression of omentin-1 was positively correlated with Barthel index or high-sensitivity C-reactive protein (hs-CRP) in patients undergoing intravenous thrombolysis for ACI. As observed from the in vitro model, Omentin-1 reduced inflammation, promoted cell growth, alleviated ROS-induced oxidative stress, and enhanced AMPK activity through activating NLRP3 ubiquitination. Omentin-1 presented ACI in the mouse model of ACI. Regulating AMPK activity contributed to controlling the effects of Omentin-1 on the in vitro model. CONCLUSIONS: Omentin-1 reduced neuroinflammation and ROS-induced oxidative stress in the mouse model of ACI, which was achieved by inhibiting NLRP3 ubiquitination through regulating AMPK activity. Therefore, omentin-1 may serve as a treatment factor for the intravenous thrombolysis of ACI in further clinical application.

RESUMEN

Patients who develop an intracerebral hemorrhage (ICH) following thrombolysis in acute ischemic stroke (AIS) have a mortality rate as high as 50%. Treatment options include blood products, such as cryoprecipitate, or antifibrinolytics, such as tranexamic acid (TXA) or ε-aminocaproic acid (EACA). Current guidelines recommend cryoprecipitate first-line despite limited data to support one agent over another. In addition, compared to antifibrinolytics, cryoprecipitate is higher in cost and requires thawing before use. This case series seeks to characterize the management of thrombolytic reversal at a single institution as well as provide additional evidence for antifibrinolytics in this setting. Patients were included for a retrospective review if they met the following criteria: presented between January 2011-January 2017, were >18 years of age, were admitted for AIS, received a thrombolytic, and received TXA EACA, or cryoprecipitate. Twelve patients met the inclusion criteria. Ten (83.3%) developed an ICH, one (8.3%) experienced gastrointestinal bleeding, and one (8.3%) had bleeding at the site of knee arthroscopy. Eleven patients received cryoprecipitate (median dose: 10 units), three received TXA (median dose: 1,000 mg), and one patient received EACA (13 g). TXA was administered faster than the first blood product at a mean time of 19 min and 137 min, respectively. Hemorrhagic expansion (N = 8, 66.67%) and inhospital mortality (N = 7, 58.3%) were high. While limited by its small sample size, this case series demonstrates significant variability in reversal strategies for thrombolysis-associated bleeding. It also provides additional evidence for the role of antifibrinolytics in this setting.

RESUMEN

BACKGROUND: Despite its approval for acute ischemic stroke >25 years ago, intravenous thrombolysis (IVT) remains underused, with inequities by age, sex, race, ethnicity, and geography. Little is known about IVT rates by insurance status. METHODS AND RESULTS: We assessed temporal trends from 2002 to 2015 in IVT for acute ischemic stroke in the Nationwide Inpatient Sample using adjusted, survey-weighted logistic regression. We calculated odds ratios for IVT for each category in 2002 to 2008 (period 1) and 2009 to 2015 (period 2). IVT use for acute ischemic stroke increased from 1.0% in 2002 to 6.8% in 2015 (adjusted annual relative ratio, 1.15). Individuals aged ≥85 years had the most pronounced increase during 2002 to 2015 (adjusted annual relative ratio, 1.18) but were less likely to receive IVT compared with 18- to 44-year-olds in period 1 (adjusted odds ratio [aOR], 0.23) and period 2 (aOR, 0.36). Women were less likely than men to receive IVT, but the disparity narrowed over time (period 1: aOR, 0.81; period 2: aOR, 0.94). Inequities in IVT resolved for Hispanic individuals in period 2 (aOR, 0.96) but not for Black individuals (period 2: aOR, 0.81). The disparity in IVT for Medicare patients, compared with privately insured patients, lessened over time (period 1: aOR, 0.59; period 2: aOR, 0.75). Patients treated in rural hospitals remained less likely to receive IVT than in urban hospitals; a more dramatic increase in urbanity widened the inequity (period 2, urban nonteaching versus rural: aOR, 2.58, period 2, urban teaching versus rural: aOR, 3.90). CONCLUSIONS: IVT for acute ischemic stroke increased among adults. Despite some encouraging trends, the remaining disparities highlight the need for intensified efforts at addressing inequities.

RESUMEN

BACKGROUND Duplicate inferior vena cava (IVC) accompanied by deep venous thrombosis is rare. The optimal treatment plan is determined according to the results of imaging, including venography. In this report, we present a case of successful treatment of a patient with duplicate IVC and deep venous thrombosis (DVT). CASE REPORT An 84-year-old man with history of hypertension was admitted to the hospital because of 4 days of moderate left lower-limb edema. A thorough examination led to the diagnosis of the DVT. The duplicate IVC was discovered during venography. As the blood from the left common iliac vein mainly flowed to the left IVC, and there were no other communicating branches before the convergence of the left and right IVCs, which was located above the 1st lumbar vertebrae body near the junction of the hepatic vein and the IVC, the strategy of placing only 1 filter in the left inferior vena cava were chosen, rather than placing 1 filter above the confluence of bilateral IVC, or placing a filter in each IVC below the level of renal veins on each side. Following that, the DVT was safely treated with thrombolysis and aspiration without the risk of pulmonary embolism. CONCLUSIONS This case report presented the complete evaluation and management of a patient with lower-limb DVT accompanied by the malformation of duplicate IVC. The filter placement strategy with duplicate IVC in the literature was summarized. We concluded that even in emergency situations, with comprehensive consideration, it is possible to perform endovascular intervention successfully and achieve satisfactory treatment results.

Smoking has detrimental effects on the cardiovascular system; however, some studies have reported better clinical outcomes after thrombolysis for ischemic stroke in smokers than in nonsmokers, a phenomenon known as the smoking paradox. Therefore, this study aimed to examine the smoking paradox in patients with ischemic stroke receiving reperfusion therapy. Data were collected from a multicenter hospital-based acute stroke registry in Fukuoka, Japan. The 1148 study patients were categorized into current and noncurrent smokers. The association between smoking and clinical outcomes, including neurological improvement (≥ 4-point decrease in the National Institutes of Health Stroke Scale during hospitalization or 0 points at discharge) and good functional outcomes (modified Rankin Scale score of 0-2) at 3 months, was evaluated using logistic regression analysis and propensity score-matched analysis. Among the participants, 231 (20.1%) were current smokers. The odds ratios (ORs) of favorable outcomes after adjusting for potential confounders were not significantly increased in current smokers (OR 0.85, 95% confidence interval [CI] 0.60-1.22 for neurological improvement; OR 0.95, 95% CI 0.65-1.38 for good functional outcome). No significant association was found in the propensity score-matched cohorts. Smoking cessation is strongly recommended since current smoking was not associated with better outcomes after reperfusion therapy.

RESUMEN

INTRODUCTION: Left-sided inferior vena cava (IVC) is an uncommon condition with a prevalence rate of 0.2% to 0.5%. Most of them remain asymptomatic and are discovered incidentally. The patient condition in this case is critical, and conventional procedures are not applicable. The surgical approach being considered is innovative, but it carries significant risks and uncertain therapeutic efficacy. PATIENT CONCERNS: A 42-year-old male presented with acute right lower extremity pain with swelling for 2 days. DIAGNOSIS: The patient was subsequently diagnosed with acute right lower extremity deep vein thrombosis, inferior vena cava thrombosis, and a left-sided IVC. INTERVENTIONS: Based on the treatment guidelines for lower extremity deep venous thrombosis. OUTCOMES: We successfully cured him with percutaneous mechanic thrombectomy (PMT) combined with catheter directed thrombolysis (CDT). CONCLUSION AND SIGNIFICANCE: The relatively low incidence of left-sided IVC does not diminish the significance of its identification. PMT combined with CDT is a safe way to treat acute thrombosis. It provides a new approach for similar patients in the future.

RESUMEN

Our study aimed to assess the benefit of intrapleural fibrinolysis before resorting to surgery to treat complicated parapneumonic effusion and empyema. We conducted a retrospective and descriptive study, including all patients hospitalized in the intensive care unit (ICU) of the Abderhaman Mami hospital, Tunisia for empyema treated with instillation of intrapleural fibrinolytic therapy between the 1st January 2000 and 31st December 2016. In all patients, empyema was diagnosed on clinical features, imaging findings (chest X-ray, thoracic echography and/or computed tomography (CT), and microbiological data. The fibrinolytic agent used was streptokinase. The efficiency of intrapleural fibrinolytic therapy was judged on clinical and paraclinical results. Among 103 cases of complicated parapneumonic effusion and empyema, 34 patients were included. The mean age was 34 years [15-81] with a male predominance (sex ratio at 2.77). Median APACH II score was 9. Fifty (50%) of the patients (n=17) had no past medical history; addictive behavior was described in 17 patients (50%). All patients were admitted for acute respiratory failure and one patient for septic shock. Pleural effusion was bilateral in 7 patients. Bacteria isolated were Streptococcus pneumonia (6 cases), Staphylococcus aureus (3 cases, including one which methicillin-resistant), Staphylococcus epidermidis (1 case), anaerobes (5 cases), and Klebsiella pneumoniae (1 case). First-line antimicrobial drug therapy was amoxicillin-clavulanate in 20 patients. A chest drain was placed in all cases in the first 38 hours of ICU admission. The median number of fibrinolysis sessions was 4 [2-9] and the median term of drainage was 7 days [3-16]. No side effects were observed. Video-assisted thoracoscopic surgery was proposed in 5 patients. The median length of hospitalization stay was 15 days [6-31]. One patient died due to multi-organ failure.

RESUMEN

The objective of this study is to determine risk factors that may contribute to exclusion decision from recombinant tissue plasminogen activator (rtPA) in patients with acute ischemic stroke (AIS) with a combined current or history of smoking and obesity. This study was conducted on data from 5469 patients with AIS collected from a regional stroke registry. Risk factors associated with inclusion or exclusion from rtPA were determined using multivariate logistic regression analysis. The adjusted odds ratios and 95% confidence interval for each risk factor were used to predict the increasing odds of an association of a specific risk factor with exclusion from rtPA. In the adjusted analysis, obese patients with AIS with a history of smoking (current and previous) excluded from rtPA were more likely to present with carotid artery stenosis (OR = 0.069, 95% CI 0.011-0.442), diabetes (OR = 0.604, 95% CI 0.366-0.997), higher total cholesterol (OR = 0.975, 95% CI 0.956-0.995), and history of alcohol use (OR = 0.438, 95% CI 0.232-0.828). Higher NIHSS score (OR = 1.051, 95% CI 1.017-1.086), higher triglycerides (OR = 1.004, 95% CI 1.001-1.006), and higher high-density lipoprotein (OR = 1.028, 95% CI 1.000-1.057) were associated with the inclusion for rtPA. Our findings reveal specific risk factors that contribute to the exclusion of patients with AIS with a combined effect of smoking and obesity from rtPA. These findings suggest the need to develop management strategies to improve the use of rtPA for obese patients with AIS with a history of smoking.

RESUMEN

BACKGROUND AND OBJECTIVES: Baseline hyperglycemia is associated with worse outcomes in acute ischemic stroke (AIS), including higher risk of symptomatic intracerebral hemorrhage (sICH) following treatment with thrombolysis. Prospective data are lacking to inform management of post-thrombolysis hyperglycemia. In a prespecified analysis from the Stroke Hyperglycemia Insulin Network Effort (SHINE) trial of hyperglycemic stroke management, we hypothesized that post-thrombolysis hyperglycemia is associated with a higher risk of sICH. METHODS: Hyperglycemic AIS patients <12 hours onset were randomized to intensive insulin (target range 80-130 mg/dL) vs standard sliding scale (80-179 mg/dL) over a 72-hour period, stratified by treatment with thrombolysis. Three board-certified vascular neurologists independently reviewed all sICH events occurring within 7 days, defined by neurologic deterioration of ≥4 points on the NIH Stroke Scale (NIHSS). Associations between blood glucose control and sICH were analyzed using logistic regression accounting for NIHSS, age, systolic blood pressure, onset to thrombolysis time, and endovascular therapy (odds ratios [OR], 95% CI). Additional analysis compared patients in a high-risk group (age older than 60 years and NIHSS ≥8) vs all others. Categorical variables and outcomes were compared using the χ2 test (p < 0.05). RESULTS: Of 1151 SHINE participants, 725 (63%) received thrombolysis (median age 65 years, 46% women, 29% Black, 18% Hispanic). The median NIHSS was 7, baseline blood glucose was 187 (interquartile range 153-247) mg/dL, and 80% were diabetic. Onset to thrombolysis time was 2.2 hours (1.6-2.9). Post-thrombolysis sICH occurred in 3.6% (3.0% intensive vs 4.3% standard glucose control, OR 1.10, 0.60-2.01, p = 0.697). In the first 12 hours, every 10 mg/dL higher glucose increased the odds of sICH (OR 1.08, 1.03-1.14, p = 0.004), and a greater proportion of glucose measures in the normal range (80-130 mg/dL) decreased the odds of sICH (0.89, 0.80-0.99, p = 0.030). These associations were strongest in the high-risk group (age older than 60 years and NIHSS ≥8). DISCUSSION: In this prespecified analysis from the SHINE trial, intensive insulin therapy was not associated with a reduced risk of post-thrombolysis sICH compared with standard sliding scale. However, early post-thrombolysis hyperglycemia was associated with a higher risk of sICH overall, particularly in older patients with more severe strokes. Further prospective research is warranted to address the risk of sICH in hyperglycemic stroke patients undergoing endovascular therapy. TRIAL REGISTRATION INFORMATION: NCT01369069.
