ABSTRACT

Resumen El accidente cerebrovascular (ACV) constituye la principal causa de discapacidad de origen neuro- lógico en los adultos mayores a 40 años y la cuarta causa de muerte en Argentina. En los últimos diez años las publicaciones indexadas relacionadas al tratamiento del ACV isquémico fueron más numerosas que las de ACV hemorrágico. El objetivo de este material es proporcionar recomendaciones locales y actualiza- das del abordaje de pacientes con hematoma intraparenquimatoso espontáneo durante la internación. Para la redacción de este manuscrito se convocó a especialistas en esta enfermedad que conformaron grupos de trabajo. Se plantearon 10 tópicos centrales expresados como epidemiologia, atención inicial, imágenes, tratamiento de la presión arterial, reversión de antitrombóticos, indicación de cirugía, profilaxis anticonvulsivante, pronóstico, prevención de complicaciones y reinicio de antitrombóticos. De cada tópico se plantearon mediante preguntas PICO los interrogantes más frecuentes de la práctica diaria. Luego de una revisión sistemática de la literatura, se generaron recomendaciones evaluadas mediante sistema GRADE y consensuadas entre autores y pacientes.


Abstract Stroke is the leading cause of neurological disability in people over 40 years of age and the fourth leading cause of death in Argentina. In the last ten years, the indexed publications related to the treatment of ischemic stroke were more numerous than those of hemorrhagic stroke. The objective of this material is to provide local and updated recommendations for the management of patients with spontaneous intracere- bral hemorrhage during hospitalization. For the writing of this manuscript, diferent specialists were convened to form working groups. Ten central topics expressed as epidemiology, initial care, imaging, blood pressure treatment, reversal of antithrombotics, indication for surgery, seizure prophylaxis, prognosis, prevention of complications and resumption of antithrombotics were raised. For each topic, the most frequent questions of daily practice were raised through PICO questions. After a systematic review of the literature, recommendations were generated, evaluated using the GRADE system and agreed between authors and patients.

ABSTRACT

Stroke is the leading cause of neurological disability in people over 40 years of age and the fourth leading cause of death in Argentina. In the last ten years, the indexed publications related to the treatment of ischemic stroke were more numerous than those of hemorrhagic stroke. The objective of this material is to provide local and updated recommendations for the management of patients with spontaneous intracerebral hemorrhage during hospitalization. For the writing of this manuscript, diferent specialists were convened to form working groups. Ten central topics expressed as epidemiology, initial care, imaging, blood pressure treatment, reversal of antithrombotics, indication for surgery, seizure prophylaxis, prognosis, prevention of complications and resumption of antithrombotics were raised. For each topic, the most frequent questions of daily practice were raised through PICO questions. After a systematic review of the literature, recommendations were generated, evaluated using the GRADE system and agreed between authors and patients.

ABSTRACT

One in 10 patients with ischemic stroke has comorbid cancer. Our goal was to compare stroke patients with cancer against those without cancer in terms of clinical and radiological features, and the underlying mechanism. We conducted a retrospective case-control study in patients admitted with ischemic stroke between July 2013 and September 2018. Cases had a concomitant diagnosis of cancer and acute ischemic stroke, controls only of ischemic stroke. Age, gender, vascular risk factors (VRF), pattern of ischemic lesion in neuroimaging, etiology and clinical outcome were compared between groups. Fifty-seven cases were identified, 61% were male (n = 35), and mean age was 75 ± 11. Fiftytwo had known oncologic disease at the onset of stroke. Most of them had solid tumors (91%, n = 52), and 54% (n = 31) had a non-metastatic tumor at the time of stroke. Prevalence of common VRF between groups was not significantly different. Previous deep venous thrombosis and pulmonary thromboembolism were more frequent in the cancer cohort (8% vs. 1%, p = 0.01). The average NIHSS was 3.8 ± 4 in the cancer group and 9 ± 7 in the control group (p = 0.01). Small artery disease as the etiology of stroke was significantly less common in the cancer group (2% vs. 26%, p = 0.001). Regarding neuroimaging, the embolic pattern was more frequent in patients with cancer (82% vs. 35%, p = 0.001). In these patients recurrence and mortality at 90 days was three and six times higher (10% vs. 3%, and 18% vs. 3%. p = 0.08 and 0.001, respectively).


Aproximadamente uno de cada 10 pacientes que sufre un accidente cerebrovascular isquémico (ACVi) padece cáncer concomitantemente. Nuestro objetivo fue evaluar características clínicoradiológicas del ACVi en pacientes con cáncer y compararlas con otros sin cáncer. Fue un estudio caso-control retrospectivo que incluyó pacientes con ACVi entre julio 2013 y septiembre 2018. Los casos tenían diagnóstico de cáncer y ACVi, y los controles solamente ACVi. Se comparó edad, sexo, factores de riesgo vascular, patrones radiológicos de lesiones, etiología y evolución clínica entre ambos grupos. Hubo 57 casos, 61% (n = 35) eran varones. La edad media fue 75 ± 11 años, sin diferencias en prevalencia de factores de riesgo vascular. En los casos hubo más pacientes con antecedentes de trombosis venosa profunda y/o tromboembolismo pulmonar (8% vs. 1%, p = 0.01). En 52 se conocía la presencia del cáncer antes del ACVi. El 91% se trató de tumores sólidos (n = 52) y en 54% el tumor no presentaba metástasis. El puntaje NIHSS promedio fue 3.8 ± 4 en los casos, y 9 ± 7 en los controles (p = 0.01). Las lesiones de pequeña arteria fueron menos frecuentes en los casos (2% vs. 26%, p = 0.001). Las lesiones de aspecto embólico fueron más comunes entre los casos (82% vs. 35%, p = 0.001). Aquellos con cáncer tuvieron menor NIHSS, menor frecuencia de lesiones de pequeña arteria, y mayor frecuencia de lesiones de aspecto embólico. La recurrencia a 90 días fue 3 veces mayor y la mortalidad 6 veces mayor en pacientes con cáncer (10% vs. 3%, y 18% vs. 3%. p = 0.08 y 0.001 respectivamente).

ABSTRACT

Neurological complications in orthotopic heart transplantation represent a major cause of morbidity and mortality despite successful transplantation. The aim of our study was to evaluate neurological complications on the outcome of patients with heart transplantation. We retrospectively studied 193 adult patients (aged = 18 years) who underwent heart transplant at Hospital Italiano in Buenos Aires from November 2014 to August 2018. We evaluated demographic and clinical vari ables and outcome of patients with and without neurological complications. We included 193 patients with a mean age of 51 ± 12 years of which 74% (n = 143) were men. The two most frequent causes that led to heart transplantation were idiopathic cardiomyopathy in 34% (n = 65) and ischemic cardiomyopathy in 29% (n = 56). Hemodynamic instability was present at the moment of transplant in 92% (n = 176) of the cases. Central neurological complications in the first week post-transplant occurred in 12% (n = 23). The most frequent were: encephalopathy (5%), subdural hematoma (2%), subarachnoid hemorrhage (2%), seizures (2%) and ischemic stroke (1%). Peripheral neuropathy was observed in 4% of cases. Hospital mortality was 11% (n = 22) and 88% (n = 170) was discharged at home. Those who presented central neurological complications had higher in-hospital mortality compared to those who did not (32% vs. 9%, p = 0.002).


Las complicaciones neurológicas posteriores al trasplante cardíaco representan una causa importante de morbimortalidad. La meta del presente estudio fue evaluar las complicaciones neurológicas (CN) en la evolución clínica de pacientes sometidos a trasplante cardíaco. Se evaluaron retrospectivamente todos los trasplantados cardíacos en el Hospital Italiano de Buenos Aires de noviembre del 2014 hasta agosto del 2018. Se evaluaron variables demográficas y clínicas, y se compararon entre los pacientes con y sin CN. Se incluyeron 193 adultos (edad = 18 años). La edad media fue de 51 ± 12 años, y 74% (n = 143) fueron varones. Las dos causas más frecuentes que llevaron a la indicación de trasplante fueron la miocardiopatía idiopática en 34% (n = 65) y la isquémica en 29% (n = 56). El 92% (n = 176) presentó inestabilidad hemodinámica al momento del trasplante. El 12% (n = 23) presentó CN centrales en la primer semana post-trasplante. Las más frecuentes fueron encefalopatía (5%), hematoma subdural (2%), hemorragia subaracnoidea (2%), convulsiones (2%), y accidente cerebrovascular isquémico (1%). En 4% se observó neuropatía periférica. La mortalidad hospitalaria fue del 11%, y 88% de los pacientes fueron dados de alta a domicilio. Los que presentaron CN centrales tuvieron mayor mortalidad intrahospitalaria en comparación a quienes no las presentaron (32% vs. 9%, p = 0.002).

ABSTRACT

Hemorrhagic transformation is a complex phenomenon where brain tissue bleeds, which could be associated or not to an increase in the neurological deficit after the acute ischemic stroke. The aim of our study was to evaluate clinical predictors of hemorrhagic transformation in patients with non-lacunar ischemic stroke. We performed a prospective analysis of the clinical records and images of patients with non-lacunar ischemic stroke. Demographics, vascular risk factors, previous medications and the information of the event in patients with and without hemorrhagic transformation were here compared. We included in this study 747 patients with non-lacunar stroke, the mean age was 77 ± 11 years and 61% were females. In the univariate analysis, the age, a history of hypertension, atrial fibrillation, chronic kidney disease and the previous use of oral anticoagulation resulted statistically significant. In the multivariate analysis of logistic regression adjusted by age and vascular risk factors: the age > 80 years (OR 3.6, CI 95% 1.8-7.6), the pulse pressure > 60 mmHg at admission (OR 5.3, CI 95% 3.2-9.1), the chronic kidney disease (OR 3, CI 95% 2.5-3.8) and the presence of previous atrial fibrillation (OR 3.5, CI 95% 2.1-6.1) were associated with and increased risk of hemorrhagic transformation. The predictors of hemorrhagic transformation in our cohort showed a relationship with severe vascular illness. The identification of these patients could influence therapeutic decisions that could increase the risk of hemorrhagic transformation.

ABSTRACT

La transformación hemorrágica es un fenómeno complejo en el que el tejido cerebral isquémico sangra; este proceso puede asociarse o no a un deterioro del estado neurológico inicial. El objetivo de nuestro estudio fue evaluar los predictores clínicos de trasformación hemorrágica en los pacientes con accidente cerebrovascular isquémico no lacunar. Se analizaron las historias clínicas y las imágenes de pacientes con infarto cerebral no lacunar incluidos prospectivamente en un programa de prevención secundaria. Se compararon datos demográficos, factores de riesgo vascular, medicación previa y datos del evento de los pacientes con transformación hemorrágica y sin ella. Se incluyeron 747 pacientes, la edad promedio fue de 77 ± 11 años, 61% mujeres. En el análisis univariado, la edad, el antecedente de hipertensión arterial, la fibrilación auricular, la insuficiencia renal crónica y la anticoagulación oral previa se relacionaron significativamente con la presencia de transformación hemorrágica. En el análisis multivariado de regresión logística ajustado por edad y factores de riesgo vascular, resultaron predictores de transformación hemorrágica: la edad > 80 años (OR 3.6; IC 95% 1.8-7.6), la presión de pulso > 60 mmHg al ingreso (OR 5.3; IC 95% 3.2-9.1), la insuficiencia renal crónica (OR 3; IC 95% 2.5-3.8) y el antecedente de fibrilación auricular (OR 3.5; IC 95% 2.1-6.1). En nuestra cohorte los predictores clínicos de conversión hemorrágica del infarto cerebral muestran una relación con la gravedad de la enfermedad vascular. La identificación de estos pacientes influenciaría en la toma de decisiones terapéuticas que pudieran incrementar el riesgo de transformación hemorrágica.

ABSTRACT

Introducción. El síndrome de apnea/hipopnea obstructiva del sueño (SAHOS) confiere mayor riesgo de enfermedad cardiovascular, dada su asociación con otros factores de riesgo vascular. Tanto el SAHOS como otros factores de riesgo vascular se asocian con lesiones cerebrales silentes. Objetivo. Evaluar la prevalencia de lesiones cerebrales silentes en pacientes con SAHOS. Pacientes y métodos. Se evaluó retrospectivamente una cohorte de 137 pacientes con SAHOS, con una edad media de 65 ± 12 años, el 45% mujeres. Las lesiones cerebrales silentes en resonancia magnética se evaluaron con la escala visual de Fazekas, y se consignó la presencia de infartos corticales, lacunares y microsangrados. Resultados. La prevalencia de factores de riesgo vascular fue: hipertensión, 64%; dislipidemia, 58%; diabetes, 18%; tabaquismo, 34%; ateromatosis carotídea, 26%; enfermedad coronaria, 13%; y fibrilación auricular, 4%. El SAHOS fue leve en el 47%, moderado en el 31% y grave en el 22% de los casos. El 91% de los pacientes tenía hiperintensidades periventriculares y el 66% presentaba lesiones en la sustancia blanca subcortical. El valor medio del índice de apnea/hipopnea fue mayor en los pacientes con mayor carga de lesiones, aunque sin significación estadística. Conclusiones. Los pacientes con SAHOS presentan una elevada prevalencia de lesiones cerebrales silentes, fundamentalmente con un patrón microangiopático. Posiblemente esto se explique por la asociación entre el SAHOS, la hipertensión arterial y otros factores de riesgo vascular (AU)


Introduction. The obstructive sleep apnea syndrome (OSA) confers increased risk of cardiovascular disease, given its association with other vascular risk factors. Both OSA and other vascular risk factors are associated with silent brain lesions. Aim. To assess the prevalence of silent brain lesions in patients with OSA. Patients and methods. We retrospectively evaluated a cohort of 137 patients with OSA. The mean age was 65 ± 12 years; 45% were women. The silent brain lesions in magnetic resonance imaging were assessed with the Visual Scale of Fazekas (FVS), and the presence of cortical infarcts, lacunar and microbleedings was assessed. Results. Vascular risk factors prevalence was: hypertension 64%, dyslipemia 58%, diabetes 18%, smoking 34%, carotid atherosclerosis 26%, coronary heart disease 13%, and atrial fibrillation 4%. OSA was mild in 47%, moderate in 31% and severe in 22% of the patients. 91% of patients had periventricular hyperintensities, and 66% showed subcortical white matter lesions. The average value of apnea/hipopnea index was higher in patients with score 2 and 3 in FVS, although without statistical significance. Conclusions. Patients with OSA in our study have a high prevalence of silent brain lesions, mainly with microangiopathic pattern. This is possibly explained by the relation between OSA, hypertension and other vascular risk factors (AU)

ABSTRACT

INTRODUCTION: The obstructive sleep apnea syndrome (OSA) confers increased risk of cardiovascular disease, given its association with other vascular risk factors. Both OSA and other vascular risk factors are associated with silent brain lesions. AIM: To assess the prevalence of silent brain lesions in patients with OSA. PATIENTS AND METHODS: We retrospectively evaluated a cohort of 137 patients with OSA. The mean age was 65 ± 12 years; 45% were women. The silent brain lesions in magnetic resonance imaging were assessed with the Visual Scale of Fazekas (FVS), and the presence of cortical infarcts, lacunar and microbleedings was assessed. RESULTS: Vascular risk factors prevalence was: hypertension 64%, dyslipemia 58%, diabetes 18%, smoking 34%, carotid atherosclerosis 26%, coronary heart disease 13%, and atrial fibrillation 4%. OSA was mild in 47%, moderate in 31% and severe in 22% of the patients. 91% of patients had periventricular hyperintensities, and 66% showed subcortical white matter lesions. The average value of apnea/hipopnea index was higher in patients with score 2 and 3 in FVS, although without statistical significance. CONCLUSIONS: Patients with OSA in our study have a high prevalence of silent brain lesions, mainly with microangiopathic pattern. This is possibly explained by the relation between OSA, hypertension and other vascular risk factors.

Tanto el SAHOS como otros factores de riesgo vascular se asocian con lesiones cerebrales silentes. Objetivo. Evaluar la prevalencia de lesiones cerebrales silentes en pacientes con SAHOS. Pacientes y metodos. Se evaluo retrospectivamente una cohorte de 137 pacientes con SAHOS, con una edad media de 65 ± 12 años, el 45% mujeres. Las lesiones cerebrales silentes en resonancia magnetica se evaluaron con la escala visual de Fazekas, y se consigno la presencia de infartos corticales, lacunares y microsangrados. Resultados. La prevalencia de factores de riesgo vascular fue: hipertension, 64%; dislipidemia, 58%; diabetes, 18%; tabaquismo, 34%; ateromatosis carotidea, 26%; enfermedad coronaria, 13%; y fibrilacion auricular, 4%. El SAHOS fue leve en el 47%, moderado en el 31% y grave en el 22% de los casos. El 91% de los pacientes tenia hiperintensidades periventriculares y el 66% presentaba lesiones en la sustancia blanca subcortical. El valor medio del indice de apnea/hipopnea fue mayor en los pacientes con mayor carga de lesiones, aunque sin significacion estadistica. Conclusiones. Los pacientes con SAHOS presentan una elevada prevalencia de lesiones cerebrales silentes, fundamentalmente con un patron microangiopatico. Posiblemente esto se explique por la asociacion entre el SAHOS, la hipertension arterial y otros factores de riesgo vascular.
