ABSTRACT

ABSTRACT Background: Ischemic stroke (IS) is a multifactorial disease that presents high rates of morbimortality in Brazil. Several studies proved that there is a link between the ABO blood group system and the occurrence of thrombotic events. Nonetheless, its association with IS is not well established. Objective: For that reason, the purpose hereof was to investigate the relation between the ABO blood groups and the occurrence of IS in a Brazilian cohort of cerebrovascular diseases. Methods: Five hundred and twenty-nine subjects were included over 12 months, from which 275 presented an IS episode and 254 composed the control group. Blood samples were drawn for direct and reverse serotyping. The control and IS groups were compared regarding the traditional risk factors and the distribution of the ABO blood groups. Results: The IS group presented a higher prevalence of systemic arterial hypertension (SAH), diabetes mellitus, smoking habits, family history, cardiopathy, and sedentary lifestyle in comparison with the control group. The AB blood type prevailed among the patients (5.1 vs. 1.6%; p<0.05) and this group had more SAH cases in comparison with the O type group (92.9 vs. 67.3%; p<0.05). Conclusions: Our results suggest that the occurrence of IS is more frequent among patients of the AB blood type.


RESUMO Antecedentes: O acidente vascular cerebral isquêmico (AVCI) é uma doença multifatorial que apresenta altas taxas de morbimortalidade no Brasil. Vários estudos provaram que existe uma ligação entre o sistema ABO de grupos sanguíneos e a ocorrência de eventos trombóticos. No entanto, sua associação com AVCI não está bem estabelecida. Objetivo: Por essa razão, o objetivo deste trabalho foi investigar a relação entre os grupos sanguíneos ABO e a ocorrência de AVCI em uma coorte brasileira de doenças cerebrovasculares. Métodos: Ao longo de 12 meses foram incluídos 529 indivíduos, dos quais 275 apresentaram um episódio de AVCI e 254 compuseram o grupo controle. Amostras de sangue foram coletadas para sorotipagem direta e reversa. Os grupos controle e AVCI foram comparados em relação aos fatores de risco tradicionais e à distribuição dos grupos sanguíneos ABO. Resultados: O grupo AVCI apresentou maior prevalência de hipertensão arterial sistêmica (HAS), diabetes mellitus, tabagismo, história familiar, cardiopatia e estilo de vida sedentário em comparação ao grupo controle. O tipo sanguíneo AB prevaleceu entre os pacientes (5,1 vs. 1,6%; p<0,05) e apresentou mais casos de HAS em comparação ao tipo O (92,9 vs. 67,3%; p<0,05). Conclusões: Nossos resultados sugerem que a ocorrência de AVCI é mais frequente entre os pacientes do tipo sanguíneo AB.

ABSTRACT

Abstract Up to 15% of all strokes affect young patients and the incidence of ischemic stroke in this population is rising. Nevertheless, there is limited information of cerebrovascular events in this population both in our country and in Latin America. The aim of our study was to evaluate the clinical characteristics and risk factors of young adults with stroke in Argentina. This is a prospective, multicenter study of stroke in young adults (18 - 55 years) in Argentina. Patients presenting with a cerebrovascular event within 180 days were included. Stroke subtypes were classified according to TOAST criteria. A total number of 311 patients were enrolled (men 53.9%, mean age: 43.3 years). Ischemic strokes occurred in 91.8% (brain infarcts 82.6%, transient ischemic attack 9.2%) and hemorrhagic strokes in 8.2%. The most frequent vascular risk factors (including ischemic and hemorrhagic strokes) were: hypertension 120 (41%), smoking 92 (31.4%), dyslipidemia 81 (27.6%) and, over weight/obesity: 74 (25.3%). Stroke subtypes were: large artery disease 12.3%, cardioembolism 7.5, small artery occlusion 11.5%, other defined etiology 27.1%, and undetermined etiology 41.6%. Our study demonstrates that vascular risk factors are very frequent in young adults with stroke. Our findings underline that urgent strategies are required for primary and secondary stroke prevention in this group of patients.


Resumen Aproximadamente un 15% de todos los ataques cerebrovasculares afectan a pacientes jóvenes y su incidencia estaría en aumento. Existe escasa información sobre el ataque cerebral en esta población tanto en nuestro país como en Latinoamérica. El objetivo de nuestro estudio fue evaluar las características clínicas y los factores de riesgo de los adultos jóvenes con ictus en Argentina. Realizamos un estudio prospectivo y multicéntrico en adultos jóvenes (18-55 años) en Argentina, que presentaron un evento cerebrovascular dentro de los 180 días previos. Los subtipos de ictus se clasificaron según los criterios de TOAST. Se incluyeron un total de 311 pacientes (hombres 53.9%, edad media: 43,3 años). Los ataques cerebrovasculares isquémicos ocurrieron en el 91.8% (infartos cerebrales 82.6%, ataque isquémico transitorio 9.2%) y los eventos hemorrágicos correspondieron al 8.2%. Los factores de riesgo vascular más frecuentes (incluyendo los eventos isquémicos y hemorrágicos) fueron: hipertensión 120 (41%), tabaquismo 92 (31.4%), dislipidemia 81 (27.6%) y sobrepeso/obesidad: 74 (25.3%). Los subtipos de ictus isquémicos fueron: arteriopatía de gran vaso 12.3%, cardioembolismo 7.5%, oclusión de pequeña arteria 11.5%, otra etiología definida 27.1% y etiología indeterminada 41.6%. Los factores de riesgo vascular son muy frecuentes en los adultos jóvenes con ictus. Nuestros hallazgos subrayan que se requieren estrategias urgentes para la prevención primaria y secundaria del ictus en este grupo particular de pacientes en nuestro país.

ABSTRACT

Resumo Fundamento O acidente vascular encefálico isquêmico (AVEi) e a doença arterial coronariana (DAC) coexistem frequentemente e compartilham fatores de risco para doença aterosclerótica. Segundo a American Heart Association , os subtipos de AVEi podem ser considerados equivalentes de risco para DAC, mas a evidência para o AVEi não-aterosclerótico não está bem definida. Além disso, o escore de cálcio coronário (CAC) é um marcador preciso para estimar o risco de DAC. Entretanto, a distribuição do CAC pelos subtipos de AVEi ainda não foi bem caracterizada. Objetivos Comparar o CAC entre os grupos de AVEi ateroscleróticos e não ateroscleróticos, e determinar quais covariáveis estão associadas a CAC alto no AVEi Métodos Em um estudo transversal, incluímos todos os pacientes com AVEi, com idades entre 45 a 70 anos no momento do acidente vascular, consecutivamente admitidos em um hospital de reabilitação entre agosto de 2014 e dezembro de 2016, sem DAC prevalente. Todos os pacientes passaram por tomografia computadorizada (TC), para medir o CAC. CAC≥100 foi considerado alto risco de DAC. O nível de significância foi p<0,05. Resultados Dos 244 pacientes estudados (média de idade de 58,4±6,8 anos; 49% do sexo feminino), 164 (67%) apresentavam etiologia não-aterosclerótica. As proporções de CAC≥100 foram semelhantes entre os grupos ateroscleróticos e não-ateroscleróticos (33% [n=26] x 29% [n=47]; p= 0,54). Entre todos os pacientes com AVEi, apenas os de idade ≥60 anos foram associados independentemente a CAC≥100 (RC 3,5; 95% IC 1,7-7,1), ajustado para hipertensão, dislipidemia, diabetes, sedentarismo, e histórico familiar de DAC. Conclusão O AVEi aterosclerótico não apresentou risco maior de DAC quando comparado ao AVEi não-aterosclerótico de acordo com o CAC. Apenas a faixa etária ≥60 anos - mas não a etiologia - foi associada independentemente a CAC≥100. (Arq Bras Cardiol. 2020; 115(6):1144-1151)


Abstract Background Ischemic Stroke (IS) and Coronary Artery Disease (CAD) frequently coexist and share atherosclerotic disease risk factors. According to the American Heart Association, IS subtypes may be considered CAD risk equivalents, but the evidence for non-atherosclerotic IS is uncertain. Additionally, the Coronary Calcium Score (CCS) is an accurate marker to address CAD risk; however, CCS distribution between IS subtypes is not well characterized. Objectives To compare the CCS between atherosclerotic and non-atherosclerotic IS groups; and to determine which covariates were associated with high CCS in IS. Methods This cross-sectional design included all patients with IS, 45 to 70 years of age at the time of the stroke, consecutively admitted to a rehabilitation hospital between August 2014 and December 2016, without prevalent CAD. All patients underwent CT scanning for CCS measurement. CCS≥100 was considered a high risk for CAD, with a significance level of p<0.05. Results From the 244 studied patients (mean age 58.4±6.8 years; 49% female), 164 (67%) had non-atherosclerotic etiology. The proportions of CCS≥100 were similar between the atherosclerotic and the non-atherosclerotic groups (33% [n=26] x 29% [n=47]; p= 0.54). Among all IS patients, only age ≥60 years was independently associated with CCS≥100 (OR 3.5; 95%CI 1.7-7.1), accounting for hypertension, dyslipidemia, diabetes, sedentarism, and family history of CAD. Conclusion Atherosclerotic IS did not present a greater risk of CAD when compared to non-atherosclerotic IS according to CCS. Only age ≥60 years, but not etiology, was independently associated with CCS≥100.

ABSTRACT

Resumen 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 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).

ABSTRACT

Abstract Introduction: Many publications on coronary surgery and carotid stenosis (CS) can be found, but we do not have enough information about the relationship between ischemic stroke, CS and non-coronary cardiac surgery. Objectives: To evaluate the incidence and risk factors associated with the stroke and CS ≥50% in patients undergoing non-coronary surgeries. Objectives: We assessed 241 patients, aged 40 years or older, between 2009 and 2016, operated in Santa Casa de Misericórdia de Ponta Grossa-PR, Brazil. We perform carotid Doppler in patients 40 years of age or older before any cardiac surgery as a routine. The incidence and possible risk factors for CS ≥50% and perioperative stroke were analyzed by univariate statistical analysis. Results: 11 patients (4.56%) presented perioperative stroke. The risk factor for stroke was CS ≥50%: OR=5.3750 (1.2909-22.3805), P=0.0208. Eighteen patients (7.46%) had CS ≥50% and their risk factors were extracardiac arteriopathy: OR=18.6607 (6.3644-54.7143), P<0.0001; COPD: OR=3.9040 (1.4491-10.5179), P=0.0071; diabetes mellitus: OR=2.9844 (1.0453-8.5204), P=0.0411; recent myocardial infarction: OR=13.8125 (1.8239-104.6052), P=0.0110; EuroSCORE II higher P=0.0056. Conclusion: The incidences of stroke and CS ≥50% were 4.56% and 7.46%, respectively. The risk factor for stroke was CS ≥50% and for CS ≥50% were extracardiac arteriopathy, COPD, diabetes mellitus, recent myocardial infarction and higher EuroSCORE II.

ABSTRACT

El accidente cerebrovascular es la tercera causa de muerte y la primera de discapacidad en la Argentina. Los eventos isquémicos constituyen el 80% de los casos. Los accidentes vasculares cerebrales requieren la implementación de protocolos sistematizados que permitan reducir los tiempos en la atención, la morbilidad y mortalidad. En el consenso participaron especialistas de nueve sociedades médicas relacionadas con la atención de pacientes con enfermedad cerebrovascular. Se consensuó un temario separado en capítulos y para la redacción de los mismos se conformaron grupos de trabajo con miembros de diferentes especialidades médicas. Se discutió y acordó para cada tema el nivel de recomendación en base a la mejor evidencia clínica disponible para cada tópico. Se realizó una adaptación al ámbito local de las recomendaciones cuando se consideró necesario. El sistema de la American Heart Association se utilizó para redactar las recomendaciones y su grado de evidencia. La corrección y edición fue realizada por cinco revisores externos, que no participaron en la redacción y con amplia experiencia en enfermedad vascular. Finalizado el documento preliminar, se organizó una reunión general con todos los integrantes de los grupos de trabajo y los revisores para redactar las recomendaciones definitivas. El consenso abarca la atención del paciente con accidente cerebrovascular isquémico en la fase pre-hospitalaria, evaluación inicial en la central de emergencias, terapias de recanalización (trombolisis y/o trombectomía mecánica), craniectomía descompresiva, neuroimágenes y cuidados clínicos en la internación.


Stroke is the third cause of death and the first cause of disability in Argentina. Ischemic events constitute 80% of cases. It requires the implementation of systematized protocols that allow reducing the time of care, morbidity and mortality. Specialists from nine medical societies related to the care of patients with cerebrovascular disease participated in the consensus. A separate agenda was agreed upon in chapters and for the writing of them, work groups were formed with members of different medical specialties. The level of recommendation was discussed and agreed upon for each topic based on the best clinical evidence available for each of them. An adaptation to the local scope of the recommendations was made when it was considered necessary.The American Heart Association system was used to draft the recommendations and their level of evidence. The correction and editing were done by five external reviewers, who did not participate in the writing and with extensive experience in vascular pathology. Once the preliminary document was finalized, a general meeting was held with all the members of the working groups and the reviewers to reach final recommendations. The consensus covers the management of ischemic stroke in the pre-hospital phase, initial evaluation in the emergency center, recanalization therapies (thrombolysis and/ or mechanical thrombectomy), decompressive craniectomy, neuroimaging and clinical care in the hospital.

ABSTRACT

Misdiagnosis is a challenging risk in young patients with ischemic stroke that leads to delayed recognition, prevents thrombolytic therapy and increases morbidity and mortality. To assess the frequency and reasons for misdiagnosis of ischemic stroke in young adults in the emergency department, we retrospectively evaluated 101 consecutive patients. The diagnosis required both the presence of an ischemic lesion in diffusion-weighted MRI as well as neurological symptoms. Twenty-three individuals were misdiagnosed (15 females, mean age 43 years [range 26-55 years]). The most common diagnostic errors included headache/ neck pain n = 11 (48%) and peripheral vertigo n = 4 (17.3%), and the most common missed etiology was arterial dissection (AD) n = 15 (65.2%). The initial diagnosis was made by emergency physicians in 22 persons. The group with misdiagnosis had a significantly higher frequency of AD at 15 vs. 8 (p < 0.01), posterior territory involvement at 12 vs. 6 (p < 0.01), and female predominance. Misdiagnosis occurred in a third of young patients with an ischemic stroke and was more frequent in those with arterial dissection involving the posterior circulation and presenting with non-specific symptoms.


El error diagnóstico es una situación riesgosa en pacientes jóvenes con infarto cerebral, ya que conduce a demora en el reconocimiento, previene la administración de terapia trombolítica e incrementa la morbimortalidad. Para valorar la frecuencia y las razones de errores en esta población, evaluamos retrospectivamente 101 pacientes consecutivos. El diagnóstico de infarto cerebral requirió tanto la presencia de lesión isquémica aguda en resonancia magnética como también la presencia de síntomas neurológicos. Veintitrés pacientes fueron mal diagnosticados (15 mujeres, edad media 43 años, [rango 26-55 años]). El error más frecuente incluyó cefalea/cervicalgia n = 11 (48%) y vértigo periférico n = 4 (17.3%). La etiología menos sospechada fue disección arterial n = 15 (62.2%). La evaluación inicial en 22 pacientes fue realizada por emergentólogos. El grupo con errores tuvo significativamente mayor frecuencia de disección arterial 15 vs. 8 (p < 0.01), afectación del territorio posterior 12 vs. 6 (p < 0.01) y sexo femenino. En conclusión, los errores diagnósticos ocurrieron en un tercio de los pacientes jóvenes con infarto cerebral, y fueron más frecuentes en aquellos con disección arterial, compromiso del territorio posterior y síntomas de presentación inespecífica.

ABSTRACT

Introducción: La isquemia cerebral es la de mayor incidencia y prevalencia entre las enfermedades cerebrovasculares y con frecuencia se asocia a la presencia del síndrome metabólico, pues muchos de sus factores de riesgo conforman este síndrome. Objetivo: Determinar la relación entre la evolución del paciente con Enfermedad Cerebrovascular Isquémica aguda y la presencia de Síndrome Metabólico. Material y Métodos: Se realizó un estudio analítico prospectivo con una muestra de 100 pacientes. Se conformaron 2 grupos, uno con pacientes con Síndrome Metabólico(SM), según criterios del NCEP/ATPIII (III Panel de Tratamiento del Adulto del Programa Nacional de Educación en Colesterol) (grupo A), y otro sin Síndrome Metabólico (grupo B) .En ambos grupos se aplicó la escala de NIHSS para evaluar la severidad y evolución de la enfermedad cerebrovascular. Resultados: En el grupo con SM prevalecieron los del sexo masculino (60 por ciento), el color de piel blanca (52 por ciento) y la media de edad fue de 61,2 años. Los principales antecedentes patológicos personales fueron Hipertensión Arterial, Cardiopatías y Tabaquismo. La severidad de la enfermedad cerebrovascular al ingreso fue peor en el grupo A (media 13,2), los que tuvieron mayor número de complicaciones neurológicas: hipertensión endocraneana y convulsiones (12 por ciento), y no neurológicas: bronconeumonía (40 por ciento) y úlceras de decúbito (28 por ciento), con un riesgo superior: OR: 6,2. Al egreso, 36 por ciento de los pacientes con SM empeoraron, según escala de NIHSS. Conclusiones: El Síndrome metabólico constituye un factor que incrementa en la Enfermedad cerebrovascular isquémica el riesgo de complicaciones, y empeora su evolución y pronóstico(AU)


Introduction: Cerebrovascular ischemia represents the highest incidence and prevalence among cerebrovascular diseases. It is frequently associated with Metabolic Syndrome because many risk factors for cerebrovascular ischemia correspond to this entity. Objective: To determine the relationship between the evolution of the patient with Acute Ischemic Cerebrovascular Disease (AICVD) and the presence of Metabolic Syndrome (MS). Material and Methods: An analytical prospective study was conducted with a sample of 100 patients, which were divided into two groups: group A, that was composed of patients with Metabolic Syndrome (MS) according to NCEP/ATPIII criteria (The Adult Treatment Panel III of the National Cholesterol Education), and group B that was composed of patients without Metabolic Syndrome. The National Institutes of Health Stroke Scale (NIHSS) was applied in both groups to evaluate the severity and evolution of cerebrovascular disease. Results: The Male sex (60 percent), and white people (52 percent) prevailed in the group with MS, and the mean age was 61,2 years. The main personal pathological antecedents were Arterial hypertension, cardiopathies, and smoking habit. The severity of cerebrovascular disease on admission was worse in group A (mean: 13,2). These patients presented a greater number of neurological complications such as: intracranial hypertension and convulsions (12 percent); they also presented non-neurological complications such as: bronchopneumonia (40 percent), and ulcers resulting from time spent on supine position (28 percent) with a higher risk (OR: 6,2). After discharge from hospital, 36 percent of patients with MS got worse, according to Scale NIHSS. Conclusions: The metabolic syndrome is a risk factor that increases the risk of complications in Ischemic Cerebrovascular Disease and worsens its evolution and prognosis(AU)

ABSTRACT

PURPOSE: Despite undergoing successful catheter ablation of typical atrial flutter (AFL), patients remain at increased risk for ischemic stroke. However, data on risk prediction tools for the development of stroke after AFL ablation are lacking. This study investigates whether CHA₂DS₂-VASc score is useful for predicting ischemic stroke after successful ablation of typical AFL. MATERIALS AND METHODS: A total of 293 patients (236 men, mean age 56.1±13.5 years) who underwent successful radiofrequency catheter ablation for typical AFL were included in this study. The clinical end point was occurrence of ischemic stroke during follow-up after AFL ablation. RESULTS: During the follow-up period (60.8±45.9 months), ischemic stroke occurred in 18 (6%) patients at a median of 34 months (interquartile range, 13–65 months). CHA₂DS₂-VASc score [hazard ratio 2.104; 95% confidence interval (CI), 1.624–2.726; p < 0.001] was an independent predictor for the occurrence of stroke after AFL ablation. The area under the receiver operating characteristic curve for CHA₂DS₂-VASc score was 0.798 (95% CI, 0.691–0.904). The CHA₂DS₂-VASc score could be used to stratify patients into two groups with different incidences of ischemic stroke (1.6% vs. 14.4%, p < 0.001) at a cutoff value of 2. CONCLUSION: CHA₂DS₂-VASc score is useful in a prediction model for the risk of stroke after catheter ablation of typical AFL.

ABSTRACT

Background: Sequelae after a stroke are common and may lead to disability. Aphasia - defined as an acquired language disturbance - can cause important limitations in quality of life. Aim: To describe the epidemiological features of patients who had an aphasia after a first episode of ischemic stroke and their functional outcome at six months. Material and Methods: Review of a database of a population study on the incidence, 30-day case fatality rate, and prognosis of stroke performed in a northern Chilean city between 2000 and 2002. Results: Aphasia was diagnosed in 28 of 142 patients in whom the disorder was sought (20%). The projected incidence rate in the city where the study was carried out is 7.06 per 100,000 inhabitants. The mean age of these 28 patients was 66 ± 20 years and 53% were women. The main risk factor for stroke was hypertension in 62%. The etiology of stroke was undetermined in 64% of these patients. Partial anterior circulation infarction was the most common stroke location in 61%. Conclusions: Twenty percent of patients with a first episode of ischemic stroke have aphasia

ABSTRACT

RESUMO: Objetivo: O estudo avaliou a tendência de hospitalização por acidente vascular encefálico isquêmico (HAVEI) e a sua mortalidade hospitalar no Brasil nos últimos 15 anos, assim como o impacto do programa Hiperdia nesse cenário. Métodos: Delineou-se um estudo ecológico com abordagem analítica e dados coletados no Sistema de Internação Hospitalar sobre episódios de AVEI, referentes aos anos de 1998 a 2012. Todos os dados foram estratificados por sexo e faixa etária, criando-se um indicador para HAVEI e proporção de mortalidade hospitalar. A fim de estimar a tendência dos dados criou-se uma curva polinomial de melhor aderência e para a averiguar o impacto do Hiperdia aplicou-se o Modelo Linear Generalizado tomados como desfecho a HAVEI e a mortalidade hospitalar. Adotou-se um nível de significância de 5% para minimizar um erro tipo I. Resultados: Foi evidenciada redução das HAVEI de 37,57/105 habitantes em 1998 a 2001 para 10,33/105 habitantes em 2002 a 2005, declinando 73,64%. A redução aconteceu em ambos os sexos, assim como para todas as faixas etárias. A mortalidade hospitalar por AVEI também declinou no Brasil a partir de 2002, tanto em homens como em mulheres, porém em menos de 3% e apenas nas faixas entre 0 e 14 anos e acima de 80 anos não detectamos tendência. Conclusão: Portanto, o declínio das HAVEI coincidiu temporalmente com a implementação do Hiperdia no ano de 2002 e essa tendência se mantém até hoje.


ABSTRACT: Objective: The study evaluated the trend of hospitalization for ischemic stroke (HIS) and its hospital mortality in Brazil over the last 15 years as well as the impact of the Hiperdia program in this scenario. Methods: An ecological study was designed with analytical approach and data collected in the Hospital Admission System on episodes of stroke, over the years 1998 to 2012. All data were stratified by sex and age, creating an indicator for HIS and proportion of hospital mortality. To estimate the trend of the data a polynomial curve fitting was created; and the Generalized Linear Model was applied to investigate the impact of Hiperdia on the endpoint HIS and hospital mortality. We adopted a 5% significance level to minimize an error type I. Results: We observed a reduction of HIS from 37.57/105 inhabitants in 1998 to 2001 to 10.33/105 inhabitants in 2002 to 2005, declining 73.64%. The reduction occurred in both sexes and for all age groups. The mortality rate of ischemic stroke also declined in Brazil since 2002, in both men and women, therefore in less than 3%; and only in the groups aged between 0 and 14 and above 80 years, we did not detect trend. Conclusion: Therefore, the decline of HIS temporally coincided with the implementation of Hiperdia in 2002 and this trend continues today.

ABSTRACT

Objective To study the incidence, clinical presentation, risk factors, imaging diagnosis, and clinical outcome of perinatal stroke. Methods Data was retrospectively collected from full-term newborns admitted to the neonatal unit of a level III maternity in Lisbon with cerebral stroke, from January 2007 to December 2011. Results There were 11 cases of stroke: nine were arterial ischemic stroke and two were cerebral venous sinus thrombosis. We estimated an incidence of arterial ischemic stroke of 1.6/5,000 births and of cerebral venous sinus thrombosis of 7.2/100,000 births. There were two cases of recurrent stroke. Eight patients presented with symptoms while the remaining three were asymptomatic and incidentally diagnosed. The most frequently registered symptoms (8/11) were seizures; in that, generalized clonic (3/8) and focal clonic (5/8). Strokes were more commonly left-sided (9/11), and the most affected artery was the left middle cerebral artery (8/11). Transfontanelle ultrasound was positive in most of the patients (10/11), and stroke was confirmed by cerebral magnetic resonance in all patients. Electroencephalographic recordings were carried out in five patients and were abnormal in three (focal abnormalities n=2, burst-suppression pattern n=1). Eight patients had previously identified risk factors for neonatal stroke which included obstetric and neonatal causes. Ten patients were followed up at outpatients setting; four patients developed motor deficits and one presented with epilepsy. Conclusions Although a modest and heterogeneous sample, this study emphasizes the need for a high level of suspicion when it comes to neonatal stroke, primarily in the presence of risk factors. The prevalence of neurological sequelae in our series supports the need of long-term follow-up and early intervention strategies. .


Objetivo Estudar incidência, apresentação clínica, fatores de risco, resultado de exames de imagem e desfecho clínico do acidente vascular cerebral perinatal. Métodos Análise retrospectiva dos prontuários de recém-nascidos a termo internados com o diagnóstico de acidente vascular cerebral perinatal no Serviço de Neonatologia, de uma maternidade nível III, em Lisboa, de janeiro de 2007 a dezembro de 2011. Resultados Houve 11 casos de acidente vascular cerebral: nove isquêmicos arteriais e duas tromboses dos seios venosos. As incidências foram estimadas: para acidente vascular cerebral isquêmico arterial de 1,6/5.000 nascimentos; para trombose dos seios venosos de 7,2/100.000 nascimentos. Houve dois casos de recorrência. Oito doentes foram sintomáticos e três assintomáticos, com diagnóstico incidental. As convulsões foram o sintoma mais frequente (8/11): clônicas generalizadas (3/8) e clônicas focais (5/8). O território vascular esquerdo foi o mais afetado (9/11), particularmente a artéria cerebral média esquerda (8/11). A ecografia transfontanelar foi positiva na maioria dos doentes (10/11), sendo o diagnóstico confirmado por ressonância magnética cerebral em todos. Dos cinco doentes que realizam eletroencefalograma, três apresentaram alterações (alterações focais n=2 e padrão de surto-supressão n=1). Oito doentes apresentaram fatores de risco para acidente vascular cerebral neonatal, incluindo causas obstétricas e neonatais. Dez doentes foram acompanhados em ambulatório, dos quais quatro apresentaram défice motores e um apresentou epilepsia. Conclusão Apesar de uma amostra limitada e heterogênea, este estudo reforça a necessidade de um elevado nível de suspeita para acidente vascular cerebral perinatal, particularmente na presença de fatores de risco. A prevalência de sequelas neurológicas em nossa série reforça a necessidade de seguimento a longo prazo e de estratégias de intervenção precoces. .

ABSTRACT

INTRODUCTION: There is still much debate regarding the kind of antithrombotic therapy in the immediate postoperative period of bioprosthesis replacement (first three months). Thus, the authors consider relevant to determine the contemporary incidence of thromboembolic events in rheumatic patients early after implantation of aortic and mitral bioprosthesis replacement (first 90 days in the post-operative period) and perform a comparison between isolated Aspirin uses versus no-antiplatelet therapy, in this same context. METHODS: Between the period of January 2010 to July 2012, all consecutive rheumatic patients, with basal sinus rhythm, who performed mitral and aortic valve replacement with bioprosthesis (pericardial bovine), were included in this prospective cohort study, 184 patients in total. The primary endpoint evaluated were the rate of embolic events. RESULTS: In the first 30 days, there were three cerebral ischemic events among patients treated in Aspirin group (5.2%) compared with two events in patients without Aspirin therapy (1.7%), HR = 3.18; 95% CI 0.5 to 19.6; P=0.33. Between 31 and 90 days postoperatively, no patient had a primary outcome. The embolism-free survival, bleeding events and the overall survival were not statistically significant between the aspirin and no-antiplatelet groups. CONCLUSION: In conclusion, in this prospective cohort of rheumatic patients, we found a low and very rare incidence rate of embolic events during the first 90 days postoperative period in mitral and isolated aortic position, respectively. The use of aspirin did not significantly reduce the rate of thromboembolism.


INTRODUÇÃO: Ainda existem controvérsias em relação à melhor estratégia de terapia antitrombótica nos três meses iniciais de pós-operatório de implante de bioprótese valvar cardíaca. Assim, os autores consideram relevante determinar a incidência contemporânea de episódios de isquemia cerebral nos meses iniciais (primeiros 90 dias de pós-operatório), e realizar uma comparação entre a aspirina isolada versus a não terapia antiplaquetária no mesmo contexto. MÉTODOS: Entre o período de janeiro de 2010 a julho de 2012, consecutivamente todos pacientes reumáticos com ritmo sinusal basal, que realizaram a substituição da valva mitral, e ou aórtica, por bioprótese (pericárdio bovino), foram incluídos neste estudo de coorte prospectivo, totalizando 184 pacientes. O desfecho primário avaliado foi a ocorrência de eventos embólicos. RESULTADOS: Nos primeiros 30 dias, três (5,2%) eventos isquêmicos cerebrais foram observados em pacientes do grupo aspirina, em comparação com dois (1,7%) eventos em pacientes sem terapia aspirina, RR = 3,18, 95% IC 0,5-19,6; P=0,33. Entre 31 e 90 dias do pós-operatório, nenhum paciente apresentou episódios de embolia cerebral ou periférica. A sobrevida livre de eventos embólicos, sangramentos e a sobrevida geral não foram estatisticamente significativas entre os grupos aspirina e não-aspirina. CONCLUSÃO: Constatou-se baixa incidência de eventos embólicos durante os primeiros 90 dias de pós-operatório de troca valvar por bioprótese envolvendo a posição mitral, e uma ainda menor para mesma situação para troca aórtica isolada. O uso da aspirina não influenciou de maneira significativa na redução de episódios tromboembólicos.

ABSTRACT

Introducción: La alteración focal aguda de la función cerebral en el adulto permite diagnosticar un accidente vascular encefálico (AVE) e iniciar precozmente el rescate de tejido cerebral. En los niños, las diferencias clínicas de esta patología en relación al adulto generan atraso, subdiagnóstico e impiden el tratamiento en la etapa aguda. Objetivo: Describir la presentación clínica y factores de riesgo del AVE isquémico en 156 niños, comparar la presentación clínica según edad y tipo de AVE. Pacientes y Método: Se analiza un registro de AVE isquémico, confirmado con imágenes cerebrales, en población menor de 18 años, iniciado en Enero 2003. Resultados: La mediana de edad: 4,9 meses (33 por ciento recién nacidos, 46 por ciento menores 6 años y 21 por ciento mayor de 6 años), 64 por ciento fueron hombres. Los infartos arteriales correspondieron al 85 por ciento y el resto fueron trombosis de senos venosos. Predominaron los signos difusos (67 por ciento) en menores de 6 años (p = 0,001). Las convulsiones fueron observadas en el 61 por ciento de los niños menores de 6 años (p = 0,03), el 33 por ciento presentó signos focales. Los factores de riesgo más frecuentes fueron patologías sistémicas agudas y cardiopatías. En 14,7 por ciento no se encontraron factores de riesgo. Conclusiones: La búsqueda de signos focales agudos de AVE no tiene utilidad diagnóstica en el niño, a diferencia de los adultos, pues su ausencia no excluye patología vascular isquémica focal. La patología sistémica aguda fue el factor de riesgo más frecuente para AVE.


Introduction: Acute focal brain dysfunction in adults serves to diagnose and to provide early rescue of the brain tissue. In children, the clinical differences of this condition compared to adults results in delayed diagnosis and treatment. Objective: To describe the clinical presentation and risk factors of CVA in 156 children and related to age and type of CVA. Patients and Method: A CVA registry of newborn to 18 years old was started in January 2003 were analized. Diagnosis was confirmed by brain imaging. Results: The median of age was 4.9 month (33 percent was newborn, 46 percent < 6 years old, 21 percent > 6 years old); 64 percent were males. Arterial ischemic stroke represented 85 percent, the rest were cerebral sinovenous thrombosis. In the clinical manifestations the diffuse signs were more frequently seen (67 percent) in children < 6 years of age (p 0.001). Seizures were observed in 61 percent in children < 6 years old (p = 0.03), 33 percent presented focal signs. The most common risk factors were acute systemic diseases and heart disease. 14.7 percent of the patients did not present risk factors. Conclusions: Acute focus signals of CVA in children have no diagnostic value, unlike adults; however absence doesn't exclude focal ischemic vascular disease. The acute systemic disease was the most common risk factor for stroke.

ABSTRACT

Single nucleotide polymorphisms in the promoter region of interleukin-18 (IL-18), an inflammatory cytokine, have been linked to susceptibility to many diseases, including cancer and immune dysfunction. Here, we explored the potential association between the IL-18 -607C/A (rs1946518) promoter region polymorphism and susceptibility to ischemic stroke (IS). This locus was amplified from peripheral blood samples of 386 IS patients (cases) and 364 healthy individuals (controls) by the polymerase chain reaction with sequence-specific primers. Significant differences were observed by the χ2 test in the -607C/A (rs1946518) genotype and allele frequencies between cases and controls (P < 0.05). Furthermore, after excluding for age, gender, smoking status, and hypertension, logistic regression indicated that IS susceptibility of -607C carriers increased 1.6 times (OR = 1.601, 95%CI = 1.148-2.233, P = 0.006) compared to -607A carriers. Additionally, similar increases in IS risk were noted for male patients or patients less than 65 years old. In conclusion, IL-18 -607C/A (rs1946518) promoter polymorphism is associated with IS susceptibility, and the C allele may confer increased IS risk.

ABSTRACT

To identify the frequency of risk factors in various subtypes of acute ischemic stroke according to TOAST criteria. Cross-sectional, observational study. Ziauddin Hospital, Karachi, from January to December 2007. Ziauddin Hospital, Karachi, from January to December 2007. Patients with acute ischemic stroke were enrolled. Studied variables included demographic profile, history of risk factors, physical and neurological examination, and investigations relevant with the objectives of the study. Findings were described as frequency percentages. Proportions of risk factors against subtypes was compared using chi-square test with significance at p< 0.05. Out of the 100 patients with acute ischemic stroke, mean age at presentation was 63.5 years. Risk factor distribution was hypertension in 85%, Diabetes mellitus in 49%, ischemic heart disease in 30%, dyslipedemia in 22%, smoking in 9%, atrial fibrillation in 5%, and previous history of stroke in 29%. The various subtypes of acute ischemic stroke were lacunar infarct in 43%, large artery atherosclerosis in 31%, acridoembolic type 8%, stroke of other determined etiology in 1% and stroke of undetermined etiology in 18%. Hypertension and Diabetes were the most association was found with ischemic heart disease [p=0.01]. Importance and relevance of risk factors evaluated for subtypes rather than ischemic stroke as a whole should be reflected in preventive efforts against the burden of ischemic stroke

ABSTRACT

To determine the characteristics of post-stroke seizures and compare these in early vs. late post-stroke seizures. Observational study. Department of Neurology, Liaquat National Hospital, Karachi, from March to September 2007. All admitted patients aged over 25 years, with diagnosis of post-stroke seizures were included. Those with known epilepsy, sepsis and eletrolyte imbalance were excluded. Age, co-morbid condition, details of seizures and radiological findings regarding type and location of stroke were collected and entered in a pre-formed proforma. Results were described as frequency and mean. Association of variables was determined through chi-square test with significance at p < 0.05. Out of the 50 patients, there were 28 [56%] males and 22 [44%] females with the mean age of 56.86 +/- 15.26 years. Thirty-one [62%] patients had history of hypertension. Early seizures i.e. within 2 weeks were seen in 29 [58%] patients. Generalized seizures were seen more frequently i.e. in 37 [74%] patients. Thirty-one [62%] subjects experienced more than 2 seizures. Forty [80%] had an ischemic stroke including 36 [72%] arterial infarct and 3 [6%] venous infarcts. Intracerebral hematoma was seen in 10 [20%] of subjects. Comparison between early and late onset seizures revealed significant association between ischemic heart disease [IHD], old stroke, hypertension and late onset seizures [p < 0.05]. Post-stroke seizures were more frequent in males, with history of hypertension, and with cortical ischemic strokes. Early seizures, multiple episodes and generalized seizure type were more common. Venous infarcts were chiefly associated with seizures at presentation. History of old stroke, ischemic heart disease, hypertension and hypercholesterolemia showed a strong relationship with the occurrence of late onset seizures

ABSTRACT

The estimated incidence of aortic dissection ranges from 5 to 30 cases per million per year. Nearly 38% of cases are missed at an initial presentation due to the wide range of clinical symptoms. We report a survivor of an inadvertent thrombolysis in acute ischemic stroke, secondary to aortic dissection.
