ABSTRACT
Introducción: el tromboembolismo pulmonar (TEP) se ha clasificado de acuerdo con las características del paciente y los hallazgos paraclínicos en riesgo bajo, intermedio y alto, siendo la mayor dificultad para el clínico el manejo del TEP de tipo intermedio, antes conocido como submasivo, donde existe controversia sobre las recomendaciones para trombólisis sistémica. Algunos autores y publicaciones señalan su uso, pero la Sociedad Europea de Cardiología (ESC) y la Asociación Americana de Hematología (ASH) no lo recomiendan. Materiales y métodos: revisión sistemática de la literatura con un total de 28 artículos extraídos de la búsqueda en las bases de datos; de estos, 7 cumplían con los criterios de inclusión (6 revisiones sistemáticas/metaanálisis y una prueba de análisis secuencial sobre ensayos aleatorizados), para un compendio de 39.879 pacientes con TEP. Resultados: dentro de los desenlaces evaluados, el sangrado mayor ocurrió en 8.1 a 9.24%, la mortalidad en quienes se les realizó trombólisis sistémica se reportó entre un 2.1 y 2.2%, encontrando disminución en el riesgo de deterioro hemodinámico al comparar la trombólisis sistémica con la anticoagulación, informando 4.1% versus 14.1% respectivamente. Discusión y conclusiones: en los estudios analizados, la trombólisis sistémica en los pacientes con TEP de riesgo intermedio no demostró impacto en cuanto a mortalidad ni desarrollo de hipertensión pulmonar secundaria, sin embargo, existe evidencia contradictoria respecto a su posible valor en la recurrencia del evento, que en la mayoría de los casos sobrepasa el riesgo de sangrado mayor (cercano a 10%).
Introduction: pulmonary embolism (PE) can be classified into low, intermediate, and high-risk, based on the patient characteristics and symptoms. Intermediate-risk PE, formerly known as submassive PE, poses the greatest challenge to clinicians, as indication for systemic thrombolytic therapy, remains controversial. Some authors and publications recommend its use, but the European Society of Cardiology (ESC) and the American Society of Hematology (ASH) do not. Materials and methods: a systematic literature review of 28 articles retrieved from search databases; of which, 7 met the inclusion criteria (6 systematic reviews/meta-analyses and a sequential analysis test on randomized trials) analyzing 39.879 PE patients. Results: among the assessed outcomes, major bleeding occurred in 8.1 to 9.24%, mortality in those who underwent systemic thrombolytic therapy was reported to be 2.1 to 2.2%; when comparing systemic thrombolytic therapy with anticoagulation therapy for preventing hemodynamic deterioration, the results were 4.1% and 14.1% respectively. Discussion and conclusions: the analyzed studies evidenced no impact on mortality or development of secondary pulmonary hypertension, in intermediate-risk PE patients receiving systemic thrombolytic therapy. However, results on its possible prevention of PE recurrence, while exceeding the risk of major bleeding (in nearly 10%), in most cases, are contradictory.

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.

INTRODUCTION: Cervical artery dissection (CAD) is the cause of 2% to 3% of ischaemic strokes and 10% to 25% of the ischaemic strokes in young people. Our objective is to evaluate whether implementation of a comprehensive stroke centre (CSC) improves the diagnosis and modifies the prognosis of patients with acute stroke due to CAD. PATIENTS AND METHODS: Retrospective study of a registry of consecutive patients with acute stroke due to CAD. They were classified according to the period of care at our centre: pre-CSC (October 2004-March 2008, 42 months) or post-CSC (April 2008-June 2012, 51 months). We compared baseline characteristics, methods of diagnosis, treatment and outcome of these patients in both periods. RESULTS: Nine patients were diagnosed with CAD in pre-CSC and 26 in post-CSC, representing 0.8% and 2.1% of all ischaemic strokes treated in each period, respectively. The diagnosis of CAD was made within the first 24 hours in 42.3% of the patients in post-CSC versus 0% in pre-CSC, by using urgent cerebral angiography as a diagnostic test in 46.2% of cases in the second period compared to 0% in the first. Both severity of stroke (median NIHSS score 11 vs. 3, P=.014) and time to neurological care (265 min vs 148, P=.056) were higher in the post-CSC period. Endovascular treatment was performed in 34.3%, and all treatments were post-CSC. The functional outcome was comparable for both periods. CONCLUSIONS: Implementation of a CSC increases the frequency of the diagnosis of CAD, as well as the treatment options for these patients in the acute phase of stroke.

Se realizó un estudio observacional sobre pacientes con el diagnóstico de infarto miocárdico agudo (IMA) en la sala de cuidados intensivos del hospital Ernesto Guevara de Las Tunas desde enero a noviembre de 2001. Se trabajaron con 39 afectados demostrando que los enfermos con un ataque cardíaco demoran entre 2 y 4 horas en llegar al cuerpo de guardia, el tiempo puerta aguja osciló entre 61 y 120 minutos. Se reportaron 3 enfermos con signos de reperfusión miocárdica para un 17 por ciento de efectividad. La primera causa de exclusión del tratamiento resultó ser la demora del enfermo en llegar al cuerpo de guardia y las principales complicaciones fueron las nauseas, los vómitos y la hipotensión(AU)
Patients with the diagnosis of myocardial infarction have been studied in the intensive care unit of Ernesto Guevara hospital of Las Tunas from January to November 2001.Thirty nine patients were studied that average 2 to 4 hours to get to the emergency room and the time drug to drug was between 1 to 2 hours. Signs of reperfusion were seen in three persons for the 17 per cent of effectiveness of the thrombolytic treatment. The first cause of exclusion was the late arrival to the emergency unit and the main complication were nausea, vomiting and hypotension(AU)
