Comparación entre tenecteplase y alteplase en la trombolisis intravenosa del ataque cerebrovascular isquémico / Comparison between tenecteplase and alteplase in intravenous thrombolysis for acute ischemic stroke / Comparação entre tenecteplase e alteplase na trombólise intravenosa do acidente vascular cerebral isquémico

Introducción: la trombolisis intravenosa es parte fundamental del tratamiento agudo de los pacientes que sufren un ataque cerebrovascular (ACV) isquémico. Existe un interés creciente en la utilización de tenecteplase como alternativa trombolítica a alteplase. El objetivo del presente trabajo es comparar la efectividad clínica de tenecteplase respecto a alteplase en la trombolisis intravenosa del ACV isquémico. Método: estudio de cohorte, bispectivo y unicéntrico, de todos los pacientes ingresados con ACV isquémico y que recibieron trombolíticos intravenosos, desde 2019 a 2022. Se compararon prospectivamente los pacientes tratados con tenecteplase con aquellos tratados con alteplase como control histórico. Se realizó test de chi cuadrado o exacto de Fisher para la asociación de variables categóricas y prueba de Wilcoxon para la comparación de medianas. Se consideró significativo un valor p menor de 0,05. Resultados: se incluyeron 69 pacientes (33 recibieron alteplase y 36 tenecteplase). La mediana de la escala de NIHSS fue de 11 (RIC 8-18) y del tiempo inicio de síntomas-aguja de 160 minutos (RIC 120-208). No se hallaron diferencias estadísticamente significatvas entre los puntajes de las escalas de coma de Glasgow y NIHSS al egreso hospitalario, así como en la escala de Rankin modificada (mRS) 0-2 y mortalidad a los seis meses, entre los dos grupos de pacientes. Tampoco hubo diferencias en las complicaciones hemorrágicas intracraneanas entre ambos grupos (13,9% para tenecteplase y 12,1% para alteplase). Conclusiones: se presenta el primer estudio acerca del tema en nuestro medio. En concordancia con los recientes ensayos internacionales, el presente trabajo no mostró diferencias significativas en los resultados clínicos de los pacientes tratados con tenecteplase o alteplase. El tenecteplase podría ser una alternativa razonable a alteplase como terapia trombolítica en el ACV isquémico, con una buena relación costo-beneficio y forma de implementación más sencilla. Se necesitan estudios aleatorizados y con un mayor número de pacientes.

Introduction: intravenous thrombolysis is a key part of the acute treatment of patients with ischemic stroke. There is a growing interest in the use of tenecteplase as a thrombolytic alternative to alteplase. The aim of this study is to compare the clinical effectiveness of tenecteplase versus alteplase in intravenous thrombolysis for ischemic stroke. Method: a single-center, bispective cohort study of all patients admitted with ischemic stroke who received intravenous thrombolytics from 2019 to 2022. Patients treated with tenecteplase were prospectively compared with those treated with alteplase as a historical control. Chi-square or Fisher's exact test was used for the association of categorical variables, and the Wilcoxon test was used for median comparison A p-value of less than 0.05 was considered significant. Results: a total of 69 patients were included in the study (33 received alteplase and 36 received tenecteplase). The median NIHSS scale score was 11 (IQR 8-18), and the median time from symptom onset to needle was 160 minutes (IQR 120-208). No statistically significant differences were found between Glasgow Coma Scale and NIHSS scores at hospital discharge, as well as in modified Rankin Scale (mRS) 0-2 and mortality at 6 months, between the two groups of patients. There were also no differences in intracranial hemorrhagic complications between both groups (13.9% for tenecteplase and 12.1% for alteplase). Conclusions: This is the first study on the topic in our setting. In line with recent international trials, our study did not show significant differences in clinical outcomes of patients treated with tenecteplase or alteplase. Tenecteplase could be a reasonable alternative to alteplase as thrombolytic therapy in ischemic stroke, with a good cost-benefit ratio and simpler implementation. Randomized studies with a larger number of patients are needed.

Não foram encontradas diferenças estatisticamente significativas entre os escores de coma de Glasgow e NIHSS na alta hospitalar, bem como na Escala de Rankin modificada (MRS) 0-2 e na mortalidade em 6 meses, entre os dois grupos de pacientes. Também não houve diferenças nas complicações hemorrágicas intracranianas entre os dois grupos (13,9% para tenecteplase e 12,1% para alteplase). Conclusões: Este é o primeiro estudo sobre o assunto em nosso meio. De acordo com estudos internacionais recentes, nosso estudo não mostrou diferenças significativas nos resultados clínicos em pacientes tratados com tenecteplase ou alteplase. A tenecteplase poderia ser uma alternativa razoável à alteplase como terapia trombolítica no AVC isquêmico, com uma boa relação custo-benefício e implementação mais fácil. São necessários estudos randomizados com um número maior de pacientes.

Desenlace funcional asociado al ataque cerebrovascular menor en una población colombiana: un estudio de cohorte / Functional outcome associated with minor stroke in a colombian population: a cohort study

RESUMEN INTRODUCCIÓN. El ACV menor hace referencia a un evento isquémico que cursa con síntomas leves. Se ha señalado que estos pacientes pueden presentar un desenlace clínico desfavorable. OBJETIVO: Evaluar el desenlace funcional a 90 días de pacientes con ACV isquémico menor, atendidos en dos hospitales de Bucaramanga, Colombia, entre los años 2015 y 2017. MÉTODOS. Estudio de cohorte en pacientes con ACV isquémico agudo y un puntaje NIHSS ≤ 5 puntos. Un desenlace clínico desfavorable a 90 días de seguimiento fue medido como un puntaje Rankin-m ≥ 3 puntos. Se realizó un análisis bivariado a través de modelos de regresión binomial simple y ajustado por edad y sexo. Un valor p <0,05 fue considerado estadísticamente significativo. RESULTADOS. Se incluyeron 90 pacientes (edad de 66,6± 13,5 años, 54,4% (n=49) de sexo masculino). El 36,5% (n=23) de los pacientes presentó un puntaje Rankin-m de 3 a 6 puntos. El antecedente de diabetes mellitus (RR: 2,50 IC 95%:1,33-4,70) y un Rankin-m previo de 2 (RR 2,12 IC 95%:1,39-3,24) fueron variables independientemente asociadas a discapacidad significativa. CONCLUSIÓN. Un estado funcional previamente comprometido, sumado a la disfunción endotelial que genera la diabetes mellitus, contribuye a un desenlace desfavorable en los pacientes con ACV menor.

ABSTRACT INTRODUCTION. Minor stroke refers to an ischemic vascular event that start with discrete symptoms. It has been suggested that these patients may have an unfavorable clinical outcome. AIM. To evaluate the functional outcome at 90 days in patients with minor ischemic stroke in two hospitals in Bucaramanga, between 2015 and 2017. METHODS. Cohort study in patients with acute ischemic stroke and NIHSS ≤ 5 points. An unfavorable clinical outcome was measured according to the modified Rankin Scale as ≥ 3 points. A bivariate analysis was performed through simple binomial regression models adjusted for age and sex. A p-value <0.05 was considered statistically significant. RESULTS. 90 patients were included (Aged 66.6 ± 13.5 years, 49 males (54%); 23 (36,5%) presented a modified Rankin score of 3-6 points. A history of diabetes (RR: 2.50 CI 95%: 1.33-4.70) and a modified Rankin score of 2 points prior to the event (RR 2.12 CI 95%: 1.39-3.24) were independently associated with significant disability CONCLUSION. A previously compromised functional state, added to the endothelial dysfunction generated by diabetes mellitus, contribute significantly to an unfavorable outcome in patients with minor stroke.

Establishment and evaluation of a predictive model for early neurological deterioration after intravenous thrombolysis in acute ischemic stroke based on machine learning / 中华危重病急救医学

OBJECTIVE@#To establish a machine learning model to predict the risk of early neurological deterioration (END) based on the clinical and laboratory data of patients with acute ischemic stroke (AIS) before intravenous thrombolysis.@*METHODS@#The clinical data of AIS patients who received intravenous thrombolytic with recombinant tissue plasminogen activator (rt-PA) at the Stroke Center of the First Hospital of Qinhuangdao City from January 2019 to July 2022 were retrospectively analyzed. Patients were divided into END group and non-END group according to whether END appeared after intravenous thrombolytic. Clinical data of patients at admission were collected, including demographic characteristics, clinical evaluation, comorbidification, drug use history, laboratory tests, etc. Univariate and multivariate Logistic regression analysis were performed to screen out the independent predictors of the END of AIS patients after intravenous thrombolytic. The study subjects were randomly divided into a training set and a test set in a 7 : 3 ratio. Four machine learning prediction models, including Logistic regression (LR), K-nearest neighbor (KNN), support vector machine (SVM) and random forest (RF), were established based on independent predictors. The receiver operator characteristic curve (ROC curve) was used to evaluate the predictive ability of each model in END.@*RESULTS@#A total of 704 patients were enrolled, of whom 99 were identified as END and 605 as non-END. Univariate and multivariate Logistic regression analysis was used to screen out the National Institutes of Health stroke scale [NIHSS, odds ratio (OR) = 1.049, 95% confidence interval (95%CI) was 1.015-1.082, P = 0.004], systolic blood pressure (OR = 1.013, 95%CI was 1.004-1.022, P = 0.004), lymphocyte percentage (LYM%, OR = 0.903, 95%CI was 0.853-0.953, P < 0.001), platelet to lymphocyte ratio (PLR, OR = 1.007, 95%CI was 1.002-1.014, P = 0.013) were the independent predictors of END in AIS patients after intravenous thrombolysis. The area under the curve (AUC) of LR, KNN, SVM, and RF machine learning models in the test dataset were 0.789 (95%CI was 0.675-0.902), 0.797 (95%CI was 0.685-0.910), 0.851 (95%CI was 0.751-0.952) and 0.809 (95%CI was 0.699-0.919), respectively. The RF model had the highest sensitivity (95.7%). The accuracy (0.736), specificity (72.0%) and AUC of SVM model were the highest, and its overall prediction ability was better than the other three models.@*CONCLUSIONS@#Machine learning models have a potential role in early predicting the risk of END after intravenous thrombolysis in AIS patients, and can provide help in clinical decision-making for intravenous thrombolysis.

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.

Effects of acupuncture on hemorrhagic transformation and motor function in stroke patients after intravenous thrombolysis with rt-PA: a prospective cohort study / 中国针灸

OBJECTIVE@#To observe the effects of the Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture on hemorrhagic transformation and limb motor function after intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in stroke patients.@*METHODS@#A total of 130 stroke patients after rt-PA thrombolytic were divided into an acupuncture group (58 cases, 1 case dropped off) and a non-acupuncture group (72 cases, 7 cases dropped off) according to whether they received acupuncture treatment. Propensity score matching (PSM) was used to match each group, with 38 patients in each group. The patients in the non-acupuncture group received rt-PA thrombolytic therapy and western medical basic treatment. In addition to the basic treatment, the patients in the acupuncture group received Xingnao Kaiqiao acupuncture at Shuigou (GV 26), bilateral Neiguan (PC 6), and ipsilateral Sanyinjiao (SP 6), Chize (LU 5), once a day for 14 days. The incidence of hemorrhagic transformation within 30 days after onset was compared between the two groups. The Fugl-Meyer assessment (FMA) score and activities of daily living (ADL) score were observed at baseline and 30 days, 6 months, 1 year after onset in the two groups. The disability rate at 6 months and 1 year after onset was recorded, and safety was evaluated in both groups.@*RESULTS@#The incidence of hemorrhagic transformation in the acupuncture group was 5.3% (2/38), which was lower than 21.1% (8/38) in the non-acupuncture group (P<0.05). At 30 days, 6 month, and 1 year after onset, the FMA and ADL scores of both groups were higher than those at baseline (P<0.01), and the scores in the acupuncture group were higher than those in the non-acupuncture group (P<0.01). The disability rate in the acupuncture group at 1 year after onset was 10.5% (4/38), which was lower than 28.9% (11/38) in the non-acupuncture group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05).@*CONCLUSION@#The Xingnao Kaiqiao acupuncture method could reduce the incidence of hemorrhagic transformation in stroke patients after intravenous thrombolysis with rt-PA, improve their motor function and daily living ability, and reduce the long-term disability rate.

Clinical Comparison of the Efficacy of Systemic Thrombolysis,Catheter-Directed Thrombolysis,and AngioJet Percutaneous Mechanical Thrombectomy in Acute Lower Extremity Deep Venous Thrombosis / 中国医学科学院学报

Objective To compare the clinical effects of three treatment methods including systemic thrombolysis(ST),catheter-directed thrombolysis(CDT),and AngioJet percutaneous mechanical thrombectomy(PMT)in acute lower extremity deep venous thrombosis(LEDVT). Methods The data of 82 patients diagnosed with LEDVT in the Department of Vascular and Gland Surgery of the First Affiliated Hospital of Hebei North University from January 2017 to December 2020 were collected.The patients were assigned into a ST group(n=50),a CDT group(n=16),and a PMT group(n=16)according to different treatment methods.The efficacy and safety were compared among the three groups. Results Compared with that before treatment,the circumferential diameter difference of both lower limbs on days 1,2,and 3 of treatment in the ST,CDT,and PMT groups reduced(all P<0.001).The PMT group showed smaller circumferential diameter difference of lower limbs on days 1,2,and 3 of treatment than the ST group(all P<0.001)and smaller circumferential diameter difference of the lower patellar margin on day 1 of treatment than the CDT group(P<0.001).The PMT group showed higher diminution rate for swelling of the affected limb at the upper and lower edges of the patella than the ST group(P<0.001)and higher diminution rate for swelling at the upper edge of the patella than the CDT group(P=0.026).The incidence of complications after treatment showed no significant differences among the three groups(all P>0.05).The median of hospital stay in the PMT group was shorter than that in the ST and CDT groups(P=0.002,P=0.001).The PMT group had higher thrombus clearance rate than the ST group(P=0.002)and no significant difference in the thrombus clearance rate from the CDT group(P=0.361).The vascular recanalization rates in the PMT(all P<0.001)and CDT(P<0.001,P=0.002,P=0.009)groups 3,6,and 12 months after treatment were higher than those in ST group,and there were no significant differences between PMT and CDT groups(P=0.341,P=0.210,P=0.341). Conclusions ST,CDT,and PMT demonstrated significant efficacy in the treatment of LEDVT,and PMT was superior to ST and CDT in terms of circumferential diameter difference of the lower limbs,diminution rate for swelling of the affected limb,thrombus clearance rate,length of hospital stay,and long-term vascular recanalization.There was no obvious difference in safety among the three therapies.

Rede de atenção às urgências e emergências: impacto da implantação da linha de cuidado ao acidente vascular cerebral / Emergency care network: impact of implementing the care pathway for stroke

Este estudo avaliou o impacto da implantação da linha de cuidado ao Acidente Vascular Cerebral (AVC) na Rede de Atenção à Urgência e Emergência (RUE) do município de Ribeirão Preto-São Paulo. Estudo retrospectivo, realizado a partir de dados secundários de adultos com AVC isquêmico no período de 2014 a 2019 atendidos pelos serviços públicos da RUE de Ribeirão Preto e submetidos à trombólise. Foram coletados dados referentes às características clínicas, epidemiológicas e gravidade dos casos, bem como tempos de atendimentos dos casos de AVC e desfechos. Os dados foram analisados por meio de técnicas descritivas, através de distribuição de frequência, medidas de posição (média e mediana) e de variabilidade (desvio padrão, intervalo interquartil). Os tempos de atendimento foram comparados em relação ao período de estudo (2014 a 2016 x 2017 a 2019) e local do primeiro atendimento (domicílio x unidade de saúde) por meio de teste Mann-Whitney. Utilizou-se o teste Qui-quadrado para analisar a associação entre período e local do primeiro atendimento com os desfechos dos casos. Participaram do estudo 403 pessoas vítimas de AVC agudo tratadas com trombólise, das quais, 53,3% do sexo masculino; 70,0% na faixa etária de 50 a 79 anos; 77,4% apresentavam hipertensão arterial sistêmica (HAS); 32,5%, Diabetes Mellitus (DM); 31,5%, dislipidemia; 31,1% faziam uso de AAS e 27,1% de estatina. No momento da admissão hospitalar, 48,6% dos casos foram considerados AVC moderado, 23,1% estado gravíssimo e 19,1% moderado a severo. O primeiro atendimento realizado no domicilio ou local do agravo aumentou de 16,9% para 38,5%, enquanto o atendimento realizado por uma Unidade de Suporte Básico aumentou de 62,8% para 77,9%. Os tempos de atendimento das pessoas submetidas à trombólise foram menores no período de 2017 a 2019 em relação a 2014 a 2016 nos tempos porta-agulha, ictus-ligação, ictus-viatura e regulação-porta. As vítimas de AVC com primeiro atendimento no domicílio ou no local da ocorrência apresentaram todos os tempos de atendimento menores quando comparados aos que foram atendidos em unidade de saúde, exceto tempo viatura-porta (o qual foi maior nas pessoas atendidas no domicílio). Não se identificou diferença no percentual dos desfechos estudados no período de 2017 a 2019 em comparação ao período de 2014 a 2016. Verificou-se maior ocorrência de craniectomia nas pessoas atendidas em domicílio do que naquelas atendidas em serviços de saúde. O percentual de ocorrência de desfechos desfavoráveis do AVC aumentou conforme a gravidade do caso. A organização do fluxo de atendimento às pessoas com sintomas de AVC mobilizou diversos serviços de saúde que integravam a RUE de Ribeirão Preto com atribuições definidas para cada nível de assistência por meio da constituição de uma linha de cuidado e da utilização de protocolos pré-estabelecidos. Tal organização reduziu os tempos de assistência pré e intra-hospitalar, os quais não possuíram influência direta sobre os desfechos dos casos, no entanto, constituíram evidências da qualidade da assistência prestada.

This study assessed the impact of implementing a care pathway for Stroke in the Emergency Care Network in the municipality of Ribeirão Preto-São Paulo. It reports a retrospective study conducted using secondary data from adult patients with ischemic stroke, treated with thrombolysis between 2014 and 2019 in the public emergency care services of Ribeirão Preto. Data regarding clinical and epidemiological characteristics, case severity, as well as stroke onset-to-treatment times and outcomes were collected. The data were analyzed using descriptive techniques, including frequency distribution, measures of central tendency (mean and median), and measures of variability (standard deviation, interquartile range). The treatment times were compared between two study periods (2014-2016 x 2017-2019) and the location of the initial care (home vs. health facility) using the Mann-Whitney test. The Chi-square test was used to analyze the association between study period, initial care location, and case outcomes. The study included 403 individuals who suffered acute stroke and were treated with thrombolysis. Of these, 53.3% were male, 70.0% were between 50 and 79 years old, 77.4% had hypertension, 32.5% had diabetes mellitus, 31.5% had dyslipidemia, 31.1% used aspirin, and 27.1% used statins. Upon hospital admission, 48.6% of cases were considered moderate stroke, 23.1% were classified as severe stroke, and 19.1% were categorized as moderate to severe stroke. The proportion of cases receiving initial care at home or at the scene increased from 16.9% to 38.5%, while care provided by Basic Support Units increased from 62.8% to 77.9%. The treatment times for individuals undergoing thrombolysis were shorter in the period 2017-2019 compared to 2014-2016 in terms of door to needle time, ictus to call time, ictus to ambulance time, and regulation to door time. Stroke victims receiving initial care at home or at the scene had shorter treatment times compared to those treated at health facilities, except for ambulance to door time, which was longer for individuals treated at home. There was no difference in the percentage of studied outcomes between the periods 2017-2019 and 2014-2016. A higher occurrence of craniectomy was observed in patients treated at home compared to those treated at health services. The percentage of unfavorable stroke outcomes increased with the severity of the cases. The organization of the care pathway for individuals with stroke symptoms mobilized various health services within the Ribeirão Preto Emergency Care Network, with defined responsibilities at each level of care through the establishment of a care pathway and the use of predefined protocols. This organization reduced pre-hospital and intra-hospital care times, which did not have a direct influence on case outcomes but provided evidence of the quality of care provided.

Introducción: el ACV constituye un problema de salud y la trombólisis sistémica una estrategia de reperfusión con alto nivel de evidencia para su tratamiento. Los reportes nacionales sobre su utilización son escasos. Objetivos: comunicar y analizar los resultados de esta terapia en el Hospital de Clínicas. Establecer predictores de buena evolución, hemorragia intracraneana y mortalidad. Métodos: estudio observacional analítico de los pacientes trombolizados en el Hospital de Clínicas (2010-2021). Resultados: se realizó trombólisis sistémica a 268 pacientes. La mediana del NIHSS al ingreso fue 12 puntos. Un 42% fueron infartos totales de la circulación anterior. La cardioembolia constituyó la etiopatogenia más frecuente. El 59,3% de los pacientes fueron externalizados con independencia funcional y 55,2% con déficit neurológico mínimo. Las tasas de hemorragia intracraneana sintomática y mortalidad fueron 7,1% y 18,7% respectivamente. El 57% de los pacientes se trataron con tiempo puerta aguja ≤60 minutos. El porcentaje de trombólisis en el total de ACV fue 18,9%. La edad, NIHSS al ingreso e internación en unidad de ACV se comportaron como variables importantes para predecir buena evolución, hemorragia intracraneana y muerte. Discusión y conclusiones: se comunicó la mayor casuística nacional sobre el tema. Los parámetros de efectividad y seguridad del tratamiento fueron comparables a los reportados internacionalmente. Se destacaron los buenos tiempos puerta aguja y tasa trombólisis sobre ACV totales como indicadores satisfactorios de calidad asistencial. La internación en unidad de ACV se comportó como un factor predictor de independencia funcional y protector frente a mortalidad hospitalaria.

Introduction: Strokes are a health problem and systemic thrombolysis constitutes a reperfusion strategy backed up by significant evidence on its positive therapeutic impact. National reports on its use are scarce. Objectives: To report and analyze results obtained with this therapeutic approach at the Clinicas Hospital. To establish predictive factors for a good evolution, intracranial hemorrhage and mortality. Method: Observational, analytical study of thrombolysed patients at Clinicas Hospital (2010-2021). Results: Systemic thrombolysis was performed in 268 patients. Average NIHSS score was 12 points when admitted to hospital.42 % of cases were total anterior circulation infarct (TACI). Cardioembolic ischaemmic stroke was the most frequent etiopahogenesis. 59.3% of patients were discharged with functional independence and 55.2% had minimal neurologic deficit. Symptomatic intracranial hemorrhage and mortality rates were 7.1% and 18.7% respectively. 57% of patients were assisted within ≤60 minutes they showed up at the ER. Thrombolysis percentage in total number of strokes was 18.9%. Age, NIHSS score upon arrival to hospital and admission to the stroke unit were significant variables to predict a good evolution, intracranial hemorrhage and death. Discussion and conclusions: The large number of cases in the country was reported. Effectiveness and safety parameters for this treatment were comparable to those reported internationally. The good door-to-needle time and thrombolysis rate versus total number of strokes stood out as satisfactory indicators of healthcare quality. Admission to the stroke unit behaved as a predictive factor of functional independence and it protected patients from hospital mortality.

Introdução: o AVC é um problema de saúde sendo a trombólise sistêmica uma estratégia de reperfusão com alto nível de evidência para seu tratamento. Os dados nacionais sobre seu uso são escassos. Objetivos: comunicar e analisar os resultados desta terapia no Hospital de Clínicas. Estabelecer preditores de boa evolução, hemorragia intracraniana e mortalidade. Métodos: estudo observacional analítico de pacientes trombolisados no Hospital de Clínicas (2010-2021). Resultados: a trombólise sistêmica foi realizada em 268 pacientes. A mediana do índice NIHSS na admissão foi de 12 pontos. 42% eram infartos totais da circulação anterior. A cardioembolia foi a etiopatogenia mais frequente. 59,3% dos pacientes tiveram alta da unidade com independência funcional e 55,2% com déficit neurológico mínimo. As taxas de hemorragia intracraniana sintomática e mortalidade foram de 7,1% e 18,7%, respectivamente. 57% dos pacientes foram tratados com tempo porta-agulha ≤60 minutos. A porcentagem de trombólise no AVC total foi de 18,9%. Idade, NIHSS na admissão e internação na unidade de AVC se comportaram como variáveis importantes para prever boa evolução, hemorragia intracraniana e óbito. Discussão e conclusões: este trabajo inclui a maior casuística nacional sobre o tema. Os parâmetros de eficácia e segurança do tratamento foram comparáveis aos descritos na bibliografia internacional. Foram destacados como indicadores satisfatórios da qualidade do atendimento os bons tempos porta-agulha e taxa de trombólise em relação ao AVC total. A internação em unidade de AVC comportou-se como preditor de independência funcional e protetor contra a mortalidade hospitalar.

Factores pronósticos de fallo de trombólisis en pacientes con diagnóstico de infarto agudo de miocardio / Prognostic factors of thrombolytic failure in patients diagnosed with acute myocardial infarction

RESUMEN Introducción: La medida terapéutica más importante en pacientes con infarto agudo de miocardio con supradesnivel del segmento ST es la reperfusión del territorio isquémico; la fibrinólisis es la estrategia primaria en muchos hospitales. El diagnóstico temprano de aquellos pacientes con riesgo de fallo de trombólisis es vital. Objetivo: Identificar los factores pronósticos de fallo de trombólisis en pacientes con diagnóstico de infarto agudo de miocardio con supradesnivel del segmento ST. Métodos: Estudio descriptivo y prospectivo que incluyó a pacientes atendidos en la Emergencia del Hospital Clínico-Quirúrgico «Joaquín Albarrán¼, con diagnóstico de la enfermedad antes mencionada, y tratados con estreptoquinasa recombinante, entre noviembre de 2018 hasta mayo de 2020. Fueron incluidos 66 pacientes en la investigación. Las variables analizadas fueron: Edad, sexo, hipertensión arterial, diabetes mellitus, tiempo entre inicio de síntomas y comienzo de fibrinólisis, localización del infarto, duración del complejo QRS, duración y profundidad de onda. Resultados: Hubo fallo de trombólisis en 27 pacientes (40,9 %). Las variables: Tiempo de realización de trombólisis, duración y profundidad de la onda Q, así como la duración del QRS mostraron valores con diferencias significativas entre ambos grupos (p<0,05). El análisis multivariado confirmó la duración y profundidad de la onda Q como factores independientes, predictores de fallo de trombólisis: (OR= 14,50; IC 95 % 1,58-132,33); (OR: 1,69; IC 95 % 1,27-2,26), respectivamente. Conclusiones: El análisis de la profundidad y duración de la onda Q en el electrocardiograma inicial de los pacientes estudiados, permite predecir a una subpoblación de pacientes con riesgo de fallo de trombólisis.

ABSTRACT Introduction: the most important therapeutic measure in patients with ST-segment elevation acute myocardial infarction is reperfusion of the ischemic territory; fibrinolysis is the primary strategy in many hospitals. Early diagnosis of those patients with risk of failed thrombolysis is vital. Objective: to identify prognostic factors of thrombolytic failure in patients diagnosed with ST- segment elevation acute myocardial infarction. Methods: a descriptive and prospective study including patients treated in the Emergency department at "Joaquín Albarrán" Clinical and Surgical Hospital, who were diagnosed with the previously mentioned disease and treated with recombinant streptokinase, between November 2018 and May 2020. A number of 66 patients were included in the investigation. Age, gender, arterial hypertension, diabetes mellitus, time between onset of symptoms and onset of fibrinolysis, location of the infarction, QRS complex duration, duration and depth of the wave were the analyzed variables. Results: thrombolysis failed in 27 patients (40.9%). Time of performing thrombolysis, duration and depth of the Q wave, as well as the QRS duration showed values with significant differences between both groups (p<0.05). The multivariate analysis confirmed the duration and depth of the Q wave as independent factors, predictors of thrombolysis failure: (OR= 14.50; 95% CI 1.58-132.33); (OR: 1.69; 95% CI 1.27-2.26), respectively. Conclusions: the analysis of the depth and duration of the Q wave in the initial electrocardiogram of the studied patients allows us to predict a subpopulation of patients with risk of failed thrombolysis.

Estrategia fármaco-invasiva en el manejo del infarto agudo al miocardio con supradesnivel del ST / Pharmaco-invasive approach in the management of acute myocardial infarction. Analysis of 144 cases

BACKGROUND: In those patients who do not have timely access to primary angioplasty, the pharmaco-invasive approach, that is, the use of thrombolysis as a bridging measure prior to the coronary angiography, is a safe alternative. AIM: To describe the features of patients with an acute ST-elevation myocardial infarction (STEMI) treated with a pharmaco-invasive strategy. MATERIAL AND METHODS: Descriptive observational study of 144 patients with mean age of 46 years with STEMI who received a dose of thrombolytic prior to their referral for primary angioplasty at a public hospital between 2018 and 2021. RESULTS: There were no differences the clinical presentation according to the Killip score at admission between thrombolyzed and non-thrombolyzed patients (p = ns). Fifty-three percent of non-thrombolyzed patients were admitted with an occluded vessel (TIMI 0) compared with 27% of thrombolyzed patients (p < 0.001). The thrombolyzed group required significantly less use of thromboaspiration (3.5 and 8.4% respectively; p = 0.014). Despite this, 91 and 92% of non-thrombolyzed and thrombolyzed patients achieved a post-angioplasty TIMI 3 flow. Long-term survival was 91 and 86% in thrombolyzed and non-thrombolyzed patients, respectively (p = ns). CONCLUSIONS: The pharmaco-invasive strategy is a safe alternative when compared to primary angioplasty in centers that don't have timely access to Interventional Cardiology.

Actuación de enfermería en el infarto cerebral agudo / Nursing performance in acute cerebral stroke

La enfermedad vascular cerebral (EVC) es una patología caracterizada por un déficit neurológico súbito, secundario a oclusión o ruptura de un vaso sanguíneo cerebral; se divide en isquémica o infarto cerebral (IC) y hemorrágica. La EVC es reconocida como la primera causa de discapacidad y la quinta causa de muerte en México, registrándose cerca de 170 mil casos nuevos al año. Existe amplia evidencia que demuestra una reducción en los desenlaces negativos, como muerte y discapacidad, al realizar intervenciones rápidas, incluyendo la administración de trombolisis intravenosa con rt-PA (activador tisular de plasminógeno recombinante) y trombectomía mecánica. La coordinación multidisciplinaria del equipo de salud y los cuidados efectivos de enfermería, son vitales durante todas las etapas de atención de la EVC. Esta revisión da a conocer un panorama general del manejo del infarto cerebral e identificar las intervenciones indispensables del profesional de enfermería realiza durante las etapas prehospitalarias, pretrombolisis, durante trombolisis y postrombolisis.

Cerebralvascular disease (CVD) is a pathology characterized by a sudden neurological deficit secondary to occlusion or rupture of a cerebral blood vessel; it is divided into ischemic or cerebral infarction (CI) and hemorrhagic. CVD is recognized as the first cause of disability and the fifth cause of death in Mexico, with nearly 170,000 new cases registered each year. There is ample evidence that shows a reduction in negative outcomes, such as death and disability, with rapid interventions, including the administration of intravenous thrombolysis with rt-PA (recombinant tissue plasminogen activator) and mechanical thrombectomy. Multidisciplinary coordination of the health care team and effective nursing care are vital during all stages of CVD care. This review provides an overview of the management of cerebral infarction and identifies essential nursing interventions during the prehospital, prethrombolysis, during thrombolysis, and postthrombolysis stages.

Experiencia en el manejo del ataque cerebrovascular isquémico en dos centros de tercer nivel de la ciudad de Ibagué (Colombia) entre junio del 2019 y junio del 2020 / Ischemic stroke management - Experience in two third-level hospitals in Ibague (Colombia) from June 2019 to June 2020

RESUMEN INTRODUCCION: El ataque cerebrovascular (ACV) de etiología isquémica es una patología cuya incidencia y mortalidad aumentaron en la última década. Cuando se maneja oportunamente, mediante trombólisis como terapia inicial, mejora su desenlace y funcionalidad. En el departamento del Tolima (Colombia) no hay registros de esta patología y en el país la bibliografía al respecto es limitada. El objetivo de este estudio es evaluar los desenlaces clínicos del manejo agudo con r-tPA en los pacientes que presentaron ACV isquémico en dos instituciones de la ciudad de Ibagué, capital de dicho departamento, entre junio del 2019 y junio del 2020, e identificar los tiempos de atención hospitalaria y las principales variables asociadas con el grupo de pacientes que fallecieron. MATERIALES Y METODOS: Estudio descriptivo de corte transversal del manejo del ACV isquémico con r-tPA, en el que se describen las variables sociodemográficas, la escala NIHSS como evaluación neurológica inicial, los tiempos de atención (inicio-aguja, puerta-tac y puerta-aguja), los desenlaces postoperatorios y el Rankin modificado al egreso. RESULTADOS: Se incluyeron 38 pacientes con una media de 67,37 años, el 60,53 % fueron mujeres. La escala NIHSS al ingreso fue 13,47 puntos (DE 5,24). Los tiempos de atención fueron 183 minutos (DE 72,63) inicio-aguja, 41 minutos (RIQ 17-72) puerta-TAC y 101,50 minutos (RIQ 77 - 137,25) puerta-aguja. La mortalidad fue del 23,68 %. CONCLUSION: La mortalidad y el desenlace funcional del ACV en nuestra población fueron similares a los reportados en la literatura nacional e internacional, sin embargo, es preciso implementar protocolos de atención del infarto cerebral para incrementar el número de pacientes con desenlace favorable, acortando los tiempos de atención en toda la cadena del tratamiento adecuado del infarto cerebral.

ABSTRACT INTRODUCTION: Ischemic stroke is a growing disease in the last decade, increasing both its incidence and its mortality. However, timely thrombolysis management as initial therapy can improve both disease progression as well as an individual's functionality. In Tolima, there are no registries of this disease and in Colombia in general, the literature is limited. The objective of this study is to investigate the clinical outcomes of the acute management of ischemic stroke using r-tPA as well as identifying in-hospital treatment times, at two institutions in Ibague between 2019 and 2020. METHODS AND MATERIALS: Using a cross-sectional descriptive study, we describe the management of ischemic stroke using r-tPA, describing sociodemographic variables, NIHSS scale as the initial neurological evaluation, in-hospital treatment times (symptoms-to-needle, door-to-TAC, door-to-needle), the clinical outcomes, and lastly the modified Rankin score upon discharge. RESULTS: We included 38 patients with median age of 67,37 years, 60,53 % were females. The initial average NIHSS scale upon admission was 13,47 (DE 5,24). In-hospital attention time averages were: symptoms-to-needle 183 minutes (DE 72,63), door-to-CAT 41 minutes (RIQ 17-72), and door-to-needle 101,50 minutes (RIQ 77-137,25). Overall the rate of mortality was 23,68 %. CONCLUSIONS: Mortality and functionality outcomes of the stroke population observed was similar to previously reported, both nationally and internationally. However, protocols should be implemented for the timely ischemic stroke management to improve the number of patients with favorable outcomes, by reducing the in-hospital attention times in all areas of the management chain.

Aplicación de terapia trombolítica en pacientes con infarto agudo de miocardio durante dos años / Two-year application of thrombolytic therapy in patients with acute myocardial infarction

RESUMEN Introducción: La estrategia trombolítica no solo mejora la esperanza de supervivencia del infarto, sino que también reduce la mortalidad general a un mes en los pacientes que reciben este tratamiento. Objetivo: Caracterizar los pacientes con infarto agudo de miocardio con elevación del segmento ST tratados con estreptoquinasa recombinante en el Hospital Clínico Quirúrgico Docente «Celia Sánchez Manduley». Métodos: Se realizó un estudio descriptivo, longitudinal y retrospectivo en 94 pacientes que recibieron tratamiento trombolítico desde diciembre de 2018 a noviembre de 2020. Las variables utilizadas fueron: edad, sexo, comorbilidades, tiempo de ventana terapéutica, causas de suspensión temporal, complicaciones, topografía, criterios de reperfusión clínico, eléctrico y enzimático y mortalidad. Se calculó la frecuencia absoluta y relativa, y la media aritmética con desviación estándar. Resultados: Predominó el sexo masculino y el grupo de edad entre 61 - 70 años. Prevalecieron los pacientes con antecedentes de hipertensión y diabetes. La hipotensión arterial fue la causa de suspensión más frecuente. El 69,1 % fueron trombolizados pasadas las 6 horas. Solo 27 pacientes sufrieron complicaciones, de las cuales, el bloqueo auriculoventricular y Killip - Kimball II fueron las más vistas. Por otra parte, 9 pacientes no presentaron criterios de reperfusión, y solo el 7,4 % fallecieron. Conclusiones: La trombolisis se realiza en una minoría de los pacientes aun en período de ventana terapéutica. La hipotensión fue la causa más frecuente de suspensión temporal de la trombolisis, y la letalidad fue inferior a la letalidad general por infarto agudo de miocardio.

ABSTRACT Introduction: thrombolytic strategy not only improves survival expectancy after infarction, but also reduces overall one-month mortality in patients receiving this treatment. Objective: to characterize patients with ST-segment elevation acute myocardial infarction treated with recombinant streptokinase at "Celia Sánchez Manduley" Clinical and Surgical Teaching Hospital. Methods: a descriptive, longitudinal and retrospective study was conducted in 94 patients who received thrombolytic treatment from December 2018 to November 2020. Age, gender, comorbidities, time-related therapeutic window, causes of temporary suspension, complications, topography, clinical, electrical and enzymatic reperfusion criteria as well as mortality were the variables used in this study. Absolute and relative frequency and arithmetic mean with standard deviation were calculated. Results: male gender and group aged 61-70 years predominated. Patients with a history of hypertension and diabetes predominated. Arterial hypotension was the most frequent cause of thrombolysis discontinuation. The 69.1 % were thrombolyzed after 6 hours. Only 27 patients suffered complications; atrioventricular block and Killip-Kimball II were the most frequently seen complications. On the other hand, 9 patients did not show reperfusion criteria and only 7.4 % died. Conclusions: thrombolysis is performed in a minority of patients even in the therapeutic window period. Hypotension was the most frequent cause of temporary suspension of thrombolysis, and case fatality was lower than the overall case fatality for acute myocardial infarction.

Reperfusion Strategies in Acute Myocardial Infarction: State of the Art

Abstract ST elevation myocardial infarction (STEMI) is a highly prevalent condition worldwide. Reperfusion therapy is strongly associated with the prognosis of STEMI and must be performed with a high standard of quality and without delay. A systematic review of different reperfusion strategies for STEMI was conducted, including randomized controlled trials that included major cardiovascular events (MACE), and systematic reviews in the last 5 years through the PRISMA ( Preferred Reporting Items for Systematic Reviews and Meta-Analysis) methodology. The research was done in the PubMed and Cochrane Central Register of Controlled Trials databases, in addition to a few manual searches. After the exclusion criteria were applied, 90 articles were selected for this review. Despite the reestablishment of IRA patency in PCI for STEMI, microvascular lesions occur in a significant proportion of these patients, which can compromise ventricular function and clinical course. Several therapeutic strategies - intracoronary administration of nicorandil, nitrates, melatonin, antioxidant drugs (quercetin, glutathione), anti-inflammatory substances (tocilizumab [an inhibitor of interleukin 6], inclacumab, P-selectin inhibitor), immunosuppressants (cyclosporine), erythropoietin and ischemic pre- and post-conditioning and stem cell therapy - have been tested to reduce reperfusion injury, ventricular remodeling and serious cardiovascular events, with heterogeneous results: These therapies need confirmation in larger studies to be implemented in clinical practice

Epidemiological analysis of stroke patients with emphasis on access to acute-phase therapies / Análise epidemiológica de pacientes com AVC com ênfase no acesso às terapias de fase aguda

ABSTRACT Background: Stroke is a public health problem. For patients with ischemic stroke, venous thrombolysis and mechanical thrombectomy are effective therapeutic options. However, even after the National Stroke Treatment Guidelines were published in 2012, the number of cases treated is still lower than expected. Objective: To identify the determining factors for obtaining access to acute-phase therapies in the state of Espírito Santo (ES) and investigate the profile of stroke patients treated at the Central State Hospital (HEC). Methods: Retrospective data from the medical records of 1078 patients from May 2018 to December 2019 were analyzed. Results: Among the 1,078 patients, 54.9% were men and the most prevalent age group was 60 to 79 years. Systemic arterial hypertension was the main single risk factor. Regarding treatment modality among the patients who arrived at the HEC within the therapeutic window, 47% received some type of acute-phase therapy. Waking up with the deficit was the main contraindication for venous thrombolysis in these cases. Conclusions: Application of the flowchart established by SESA-ES seemed to be effective for enabling responsiveness of care for stroke victims. Public emergency transport services had a fundamental role in this process. In addition, the care provided by the tertiary stroke center provided excellent access to acute-phase therapies. However, despite the efficiency of the service provided at the HEC, it only reached a maximum of 50% of the ES population. This service model therefore needs to be expanded throughout the state.

RESUMO Antecedentes: O acidente vascular cerebral (AVC) é um problema de saúde pública. Nos casos de AVC isquêmico, a trombólise venosa e a trombectomia mecânica são efetivas opções terapêuticas de fase aguda. Entretanto, mesmo com a Diretriz Nacional de AVC publicada desde 2012, o número de casos tratados ainda é baixo. Objetivo: Apurar os fatores determinantes para o acesso às terapias de fase aguda na realidade espírito-santense e investigar o perfil dos pacientes de AVC atendidos no Hospital Estadual Central de Vitória (HEC). Métodos: O presente estudo analisou dados retrospectivos de prontuários de 1.078 pacientes no período de maio de 2018 a dezembro de 2019. Resultados: Dos 1.078 pacientes, 54,9% eram homens e a faixa etária mais prevalente foi a de 60 a 79 anos. A hipertensão arterial sistêmica foi o principal fator de risco isolado. Quanto ao tratamento, identificou-se que entre os pacientes que chegaram ao HEC na janela terapêutica 47% receberam terapia de fase aguda e que acordar com o déficit foi a principal contraindicação para trombólise venosa nesses casos. Conclusões: As análises demonstraram que a aplicação do fluxograma estabelecido pela Secretaria de Estado da Saúde do Espírito Santo parece ser eficaz na agilidade de atendimento das vítimas de AVC e que o Serviço de Atendimento Móvel de Urgência tem um papel fundamental nesse processo. Além disso, a assistência de um centro terciário de AVC permite acesso às terapias de fase aguda com excelência. Todavia, mesmo que o modelo de serviço prestado no HEC seja eficiente, ele atinge no máximo 50% da população do ES, sendo necessária a sua ampliação.
