Rigidez carotídea y riesgo de eventos vasculares y mortalidad: el estudio REGICOR / Carotid artery stiffness and risk of vascular events and mortality: the REGICOR study

Introducción y objetivos: Los objetivos son analizar la relación dosis-respuesta de la rigidez de la arteria carótida y la mortalidad y evaluar su capacidad predictiva. Métodos: Estudio de cohorte poblacional que incluyó a 6.468 participantes, con una mediana de seguimiento de 6,5 años. Se evaluaron 6 índices de rigidez. Se identificaron los eventos coronarios y cerebrovasculares y la mortalidad. Resultados: La rigidez carotídea, el coeficiente de Peterson y la velocidad de la onda de pulso (VOP) se asociaron de manera lineal y directa con los eventos cerebrovasculares: aumento del 8% (IC95%, 1-16%) por unidad de rigidez, del 7% (IC95%, 2-13%) cada 10 unidades del coeficiente de Peterson y del 26% (IC95%, 8-48%) por unidad de la VOP. La tensión carotídea se asoció de modo no lineal con el riesgo de enfermedad coronaria: en valores <0,09 unidades, cada aumento de 0,01 unidades se asoció con una disminución de un 16% del riesgo (IC95%, –33 a +6%); por encima de 0,09 unidades, cada incremento de 0,01 unidades se asoció con un aumento de un 16% del riesgo (IC95%, 6-27%). La inclusión de estos índices no mejoró la capacidad predictiva de las funciones de riesgo. Conclusiones: La rigidez carotídea, el coeficiente de elasticidad de Peterson y la VOP tienen una relación lineal y directa con el riesgo de enfermedad cerebrovascular. La tensión (strain) carotídea tiene una relación en U con el riesgo de enfermedad coronaria. Estos índices no contribuyen a mejorar la capacidad predictiva de las funciones de riesgo. (AU)

Introduction and objectives: The aims of this study were to determine the dose-response association of carotid arterial stiffness with vascular outcomes and overall mortality, and to assess their added predictive capacity. Methods: Population-based cohort study including 6468 individuals, with a median follow-up of 6.5 years. Six carotid artery stiffness indices were assessed: strain, stiffness, Peterson elasticity coefficient, compliance coefficient, distensibility coefficient, and pulse wave velocity (PWV). Incident coronary, cerebrovascular, global vascular, and total fatal events were identified. Results: Carotid compliance and distensibility coefficients were not associated with any of the outcomes. Carotid stiffness, Peterson elasticity coefficient, and PWV showed a direct linear relationship to cerebrovascular disease: the risk increased by 8% (95%CI, 1-16) per stiffness unit increase, by 7% (95%CI, 2-13) per 10-unit Peterson elasticity coefficient increase, and by 26% (95%CI, 8-48) per PWV unit increase. Carotid strain showed a nonlinear association with ischemic heart disease. When strain was ≤ 0.09 units, each 0.01-unit increase was associated with a 15% lower risk of coronary events (95%CI,−33 to 6); above 0.09 units, each 0.01 increase in strain was associated with a 16% higher risk of coronary events (95%CI, 6-27). The addition of the stiffness indices did not improve the predictive capacity of validated risk functions. Conclusions: Carotid stiffness, Peterson elasticity coefficient, and PWV have a direct linear association with cerebrovascular disease risk. Carotid strain is not linearly related to U-shaped ischemic heart disease risk. The inclusion of these indexes does not improve the predictive capacity of risk functions. (AU)

Asociación entre periodontitis, enfermedad cerebrovascular y demencia. Informe científico del Grupo de Trabajo de la Sociedad Española de Periodoncia y la Sociedad Española de Neurología / The association between periodontitis, cerebrovascular disease, and dementia. Scientific report of the Working Group of the Spanish Society of Periodontology and the Spanish Society of Neurology

Objetivo: Revisar la evidencia científica disponible sobre la relación entre la periodontitis y las enfermedades neurológicas, en particular la enfermedad cerebrovascular y la demencia. Además, se facilitan una serie de recomendaciones en relación con la prevención y el manejo de la periodontitis y estas enfermedades neurológicas desde las consultas dentales y las unidades de neurología. Desarrollo: Se realizó una búsqueda bibliográfica sin restricción en cuanto al diseño del estudio para identificar aquellos artículos más relevantes sobre la asociación entre periodontitis, enfermedad cerebrovascular y demencia desde un punto de vista epidemiológico, de intervención, así como de mecanismos biológicos involucrados en estas relaciones, y así responder a diferentes preguntas planteadas por los miembros del Grupo de Trabajo SEPA-SEN. Conclusiones: La periodontitis aumenta el riesgo de ictus isquémico y demencia de tipo Alzheimer. Bacteriemias recurrentes con aumento de un estado inflamatorio sistémico de bajo grado parecen ser posibles mecanismos biológicos que explicarían esta asociación. Una evidencia limitada apunta a que diferentes intervenciones de salud oral pueden reducir el riesgo futuro de padecer enfermedad cerebrovascular y demencia.(AU)

Objective: This article reviews the scientific evidence on the relationship between periodontitis and neurological disease, and particularly cerebrovascular disease and dementia. We also issue a series of recommendations regarding the prevention and management of periodontitis and these neurological diseases at dental clinics and neurology units. Development: In response to a series of questions proposed by the SEPA-SEN Working Group, a literature search was performed, with no restrictions on study design, to identify the most relevant articles on the association between periodontitis and cerebrovascular disease and dementia from the perspectives of epidemiology, treatment, and the biological mechanisms involved in these associations. Conclusions: Periodontitis increases the risk of ischaemic stroke and Alzheimer dementia. Recurrent bacterial infections and increased low-grade systemic inflammation seem to be possible biological mechanisms underlying this association. Limited evidence suggests that various oral health interventions can reduce the future risk of cerebrovascular disease and dementia.(AU)

CONCLUSIONS: Carotid stiffness, Peterson elasticity coefficient, and PWV have a direct linear association with cerebrovascular disease risk. Carotid strain is not linearly related to U-shaped ischemic heart disease risk. The inclusion of these indexes does not improve the predictive capacity of risk functions.

Síndrome fronto-subcortical: cuando la red falla, a propósito de un caso / Frontal-subcortical syndrome: When the network fails, about a case

La depresión y el parkinsonismo son consecuencias directas de una lesión, por lo general vascular, que compromete alguna estructura del circuito fronto-subcortical. Su detección representa un desafío diagnóstico, y tiene importantes repercusiones en el manejo terapéutico. Se presenta el caso de un paciente varón de 79 años con buena situación basal global, que ingresa a una unidad de psicogeriatría tras un intento autolítico. Inicialmente se objetiva una depresión franca no psicótica, y llama la atención un aumento de la base de sustentación a la marcha y bradicinesia. Tras el ajuste de tratamiento antidepresivo se evidencia una notable mejoría de la sintomatología afectiva, pero no motora, por lo que se decide solicitar una resonancia magnética que objetiva lesiones isquémicas en ganglios basales. Este caso representa un claro soporte del modelo de circuitos fronto-subcorticales, en el que la presentación clínica, la evaluación neuropsiquiátrica, los datos de neuroimagen y la respuesta terapéutica contribuyen a la comprensión de los déficits que siguen a la lesión de estas estructuras Consideramos que con este artículo se podrá contar con una información breve y precisa con relación a los mecanismos fisiopatológicos, evaluación, planteamiento diagnóstico y tratamiento del síndrome fronto-subcortical (AU)

Depression and parkinsonism are direct consequences of a lesion, usually vascular, that affects some structure of the frontal-subcortical circuit. Their detection represents a diagnostic challenge and has important repercussions in therapeutic management. The case is presented of a 79-year-old male patient with good overall baseline status, who was admitted to a Psychogeriatric Unit after an autolytic attempt. Initially, a non-psychotic frank depression is observed, and an increase in the base of support for walking and bradykinesia is noted. After adjustment of antidepressant treatment, a notable improvement in affective symptoms is evidenced but not in motor symptoms, so it is decided to request a magnetic resonance imaging that shows ischemic lesions in the basal ganglia. This case provides clear support for the frontal-subcortical circuit model, in which the clinical presentation, neuropsychiatric evaluation, neuroimaging data and therapeutic response contribute to understanding the deficits following these types of lesions. We believe that this article will provide brief and accurate information on the pathophysiological mechanisms, evaluation, diagnostic approach, and treatment of the frontal-subcortical syndrome (AU)

Hemorrhagic Cerebrovascular Disease: An Unusual Presentation of Hyperhomocysteinemia / Accidente cerebrovascular hemorrágico: una inusual presentación de hiperhomocisteinemia / Acidente vascular cerebral hemorrágico: uma apresentação incomum da hiper-homocisteinemia

Introduction: Stroke is a major cause of morbidity and mortality worldwide, with hemorrhagic stroke being the deadliest form of acute stroke. Therefore, the cause of the event should be determined to direct the associated therapy and take preventive measures. Hyperhomocysteinemia has been described as a rare etiology of stroke. Although hyperhomocysteinemia has been associated with venous thrombotic events, altered endothelial function, and procoagulant states, its clinical role in stroke remains controversial. Case description: We present a case of a 60-year-old male patient with primary autoimmune hypothyroidism who presented with dysarthria, facial paresis, and left upper-limb monoparesis after sexual intercourse. A simple skull computed tomography scan showed hyperintensity in the right basal ganglion, indicating an acute hemorrhagic event. Etiological studies were performed, including ambulatory blood pressure monitoring, cerebral angiography, and transthoracic echocardiogram, which ruled out underlying vascular pathology. During follow-up, vitamin B12 deficiency and hyperhomocysteinemia were detected, without other blood biochemical profile alterations. Supplementation was initiated, and homocysteine levels gradually decreased, without new neurological deficits observed during follow-up. Conclusion: Quantification of homocysteine should be considered in patients with a cerebrovascular disease without apparent cause, as documenting hyperhomocysteinemia and correcting its underlying etiology are essential not only for providing appropriate management but also for preventing future events.

Introducción: el accidente cerebrovascular es una causa importante de morbilidad y mortalidad en todo el mundo, y el accidente cerebrovascular hemorrágico es la forma más mortífera de accidente cerebro- vascular agudo. La determinación de la causa del evento es esencial para dirigir la terapia asociada y poder tomar medidas preventivas. La hiperhomocisteinemia se ha descrito como una etiología poco frecuente de accidente cerebrovascular. Aunque esta se ha asociado con eventos trombóticos venosos, disfunción endotelial alterada y estados procoagulantes, sigue siendo controvertido su papel clínico en el accidente cerebrovascular. Descripción del caso: se presenta el caso de un hombre de 60 años con hipotiroidismo autoinmune primario que presentó disartria, paresia facial y monoparesia del miembro superior izquierdo después de un encuentro sexual. Una simple tomografía computarizada de cráneo mostró hipointensidad en la región del ganglio basal derecho, que indicaba un evento hemorrágico agudo. Se realizaron estudios etiológicos, incluyendo monitorización ambulatoria de la presión arterial, angiografía cerebral y ecocardiograma transtorácico, que descartaron patología vascular subyacente. Durante el seguimiento, se detectó deficiencia de vitamina B12 e hiperhomocisteinemia, sin otras alteraciones en el perfil bioquímico sanguíneo. Se inició la suplementación y los niveles de homocisteína disminuyeron gradualmente, sin observar nuevos déficits neurológicos durante el seguimiento. Conclusión: la cuantificación de homocisteína debe ser considerada en casos de enfermedad cerebrovascular sin causa aparente, dado que documentar la hiperhomocisteinemia y corregir su etiología subyacente es esencial no solo para proporcionar un manejo adecuado, sino también para prevenir eventos futuros.

Introdução: o acidente vascular cerebral (AVC) é uma das principais causas de morbidade e mortalidade em todo o mundo, sendo o AVC hemorrágico a forma mais letal de AVC agudo. A determinação da causa do evento é essencial para direcionar a terapia associada e poder tomar medidas preventivas. A hiperhomocisteinemia tem sido descrita como uma etiologia rara de acidente vascular cerebral. Embora a hiper-homocisteinemia tenha sido associada a eventos trombóticos venosos, disfunção endotelial alterada e estados pró-coagulantes, seu papel clínico no AVC permanece controverso. Descrição do caso: apresentamos o caso de um homem de 60 anos com hipotireoidismo autoimune primário que apresentou disartria, paresia facial e monoparesia do membro superior esquerdo após relação sexual. A tomografia computadorizada de crânio mostrou hipointensidade na região do gânglio da base direito, indicando evento hemorrágico agudo. Foram realizados estudos etiológicos, incluindo monitorização ambulatorial da pressão arterial, angiografia cerebral e ecocardiograma transtorácico, que descartaram patologia vascular subjacente. Durante o acompanhamento, foram detectados deficiência de vitamina B12 e hiper-homocistei- nemia, sem outras alterações no perfil bioquímico sanguíneo. A suplementação foi iniciada e os níveis de homocisteína diminuíram gradualmente, sem novos déficits neurológicos observados durante o acompanhamento. Conclusão: a quantificação da homocisteína deve ser considerada em casos de doença vascular cerebral sem causa aparente, pois documentar a hiper-homocisteinemia e corrigir sua etiologia subjacente é essencial não apenas para fornecer manejo adequado, mas também para prevenir eventos futuros.

Hypertensive and overweight patients related to the greater severity of cerebrovascular disease, hyperglycemic patients with high cholesterol and triacylglyceride values ​​predominated, and in them the cerebral ischemic event was more severe. Arterial hypertension and ischemic heart disease prevailed in the studied population with 81.8 and 52.7 respectively. Conclusions: cerebrovascular disease was more frequent in males, white skin color and elderly patients. Arterial hypertension, overweight, hyperglycemia as well as high cholesterol and triglyceride values ​​predominated in the sample and were related to the greater severity of the ischemic cerebrovascular event.

Impacto de la superación profesional en la meteoro labilidad de la enfermedad cerebrovascular / Climate change and cardiovascular disease: impact of professional development

Introducción: La enfermedad cerebrovascular (ECV) es una urgencia neurológica que en ocasiones se encuentra influenciada por los cambios del tiempo. La ECV isquémica es una emergencia médica con una ventana estrecha para su diagnóstico y tratamiento. El daño generado por esta enfermedad se estima mediante de la mortalidad, discapacidad e impacto social. Objetivo: Proponer un programa de capacitación basado en los efectos fisiopatológicos que provocan en los pacientes, cambios de tiempo y ritmo circadiano en el contexto de la adaptación al cambio climático. Método: Se desarrolló un estudio multietápico prospectivo en el Hospital Universitario Mártires del 9 de Abril del municipio Sagua la Grande entre los años 1993 a 2017. En la primera etapa se seleccionó un universo de 52 profesionales de la salud que atendieron a estos pacientes; en la segunda, 48 y en la tercera, 61. Resultados: El nivel de conocimiento del personal de salud en una primera etapa era inadecuado (78,85 %); en la tercera, este porcentaje disminuyó (14,75 %). Como resultado de la capacitación mejoraron los tiempos de atención a los pacientes con ECV a su llegada al hospital, y en la tercera, más del 50 % de los enfermos fueron atendidos antes de las seis horas de inicio de los síntomas. Conclusiones: La capacitación sobre ECV basada en los efectos fisiopatológicos que provocan en los pacientes el cambio climático y el ritmo circadiano disminuyó el tiempo de espera, y se asoció con una reducción de la morbilidad y la mortalidad, después de aplicar este programa.

Introduction: cerebrovascular disease (CVD) is a neurological emergency that is sometimes influenced by climate changes. Ischemic CVD is a medical emergency with a narrow window for diagnosis and treatment. The damage generated by this disease is estimated through mortality, disability and social impact. Objective: to propose a training program based on the pathophysiological effects in patients caused by changes in time and circadian rhythm in the context of adaptation to climate change. Methods: a multistage prospective study was conducted at "Mártires del 9 de Abril" University Hospital in Sagua la Grande municipality between 1993 and 2017. A universe of health professionals who cared for these patients was selected as follows: 52 in the first stage; 48 in the second stage, and 61 in the third ones. Results: the level of knowledge of health personnel in the first stage was inadequate (78.85%); this percentage decreased in the third stage (14.75%). Care times for CVD patients improved upon arrival at the hospital as a result of the training, as well as in the third ones, more than 50% of the patients were seen within six hours of the onset of symptoms. Conclusions: CVD training based on the pathophysiological effects of climate change and circadian rhythm on patients decreased waiting time, and was associated with reduced morbidity and mortality, after applying this program.

Infarto medular: etiología, hallazgos radiológicos y factores pronósticos en una serie de 41 pacientes / Spinal cord infarction: aetiology, imaging findings, and prognostic factors in a series of 41 patients

Introducción: El infarto medular es una entidad infrecuente y con elevada morbilidad. El diag-nóstico puede resultar difícil y el tratamiento óptimo sigue siendo controvertido. Existen pocasseries de casos publicadas.Métodos: Estudio retrospectivo de infarto medular en un hospital terciario desde 1999 a 2020.Se evaluaron la etiología, las características clínicas, radiológicas, terapéuticas y pronósticas.Resultados: Se incluyeron 41 pacientes (58,5% varones, edad media 61 ±17 a˜nos). Treinta y unpacientes (75,6%) presentaban factores de riesgo vascular (FRV). Presentaron déficit motor (39,95,1%), dolor (20, 48,8%), déficit sensitivo (33, 80,4%) y alteración autonómica (24, 58,5%). Serealizó resonancia magnética (RM) en 37 pacientes (90,2%). En los 12 pacientes con secuenciasde difusión, esta estaba alterada en 10. La localización más afectada fue la dorsal (68,2%). Serealizó estudio vascular en 33 pacientes (80,4%). Las etiologías más frecuentes fueron disecciónaórtica en 6, ateroesclerosis demostrada en estudio vascular en 6, embolia fibrocartilaginosa en6, posquirúrgico en 5 e hipotensión en 4. El mecanismo etiológico quedó sin filiar en 12 pacientes(29,3%), 9 presentaban FRV. Al final del periodo de seguimiento (mediana 24 meses, rangointercuartílico 3-70), 12 pacientes (29,2%) presentaban deambulación autónoma. La presenciade FRV y la paraparesia se asociaron significativamente a peor pronóstico (p < 0,05).Discusión: El infarto medular es una patología con una etiología variada, que en muchos delos pacientes queda sin resolver. El pronóstico funcional a largo plazo es malo y depende de lascaracterísticas basales del paciente y de la forma de presentación clínica. La RM, especialmentelas secuencias de difusión, es útil en el diagnóstico precoz.(AU)

Introduction: Spinal cord infarction is a rare disease with a high rate of morbidity. Its diagnosiscan be challenging and controversy remains regarding the best treatment. Few case series havebeen published.Methods: We conducted a retrospective review of cases of spinal cord infarction attended ina tertiary hospital from 1999 to 2020. Aetiology and clinical, imaging, and prognostic featureswere assessed.Results: Forty-one patients (58.5% men, mean [standard deviation] age 61 [17] years) wereincluded in the study. Thirty-one patients (75.6%) presented vascular risk factors. Motor deficitswere recorded in 39 (95.1%), pain in 20 (48.8%), sensory deficits in 33 (80.4%), and autonomicdysfunction in 24 (58.5%). MRI was performed in 37 (90.2%) patients. Diffusion-weighted imageswere available for 12 patients, with 10 showing diffusion restriction. The thoracic region wasthe most frequently affected (68.2%). Vascular imaging studies were performed in 33 patients(80.4%). The most frequent aetiologies were aortic dissection (6 cases), atherosclerosis demons-trated by vascular imaging (6 cases), fibrocartilaginous embolism (6 cases), surgery (5 cases),and hypotension (4 cases). Aetiology was undetermined in 12 patients (29.3%), although 9 ofthese presented vascular risk factors. At the end of the follow-up period (median, 24 months;interquartile range, 3-70), 12 patients (29.2%) were able to walk without assistance. Vascularrisk factors and paraparesis were significantly associated with poorer prognosis (P < .05).Discussion: Spinal cord infarction may present diverse aetiologies, with the cause remainingundetermined in many patients. Long-term functional prognosis is poor, and depends on baselinecharacteristics and clinical presentation. MRI, and especially diffusion-weighted sequences, isuseful for early diagnosis.(AU)

At the end of the follow-up period (median, 24 months; interquartile range, 3-70), 12 patients (29.2%) were able to walk without assistance. Vascular risk factors and paraparesis were significantly associated with poorer prognosis (P < .05). DISCUSSION: Spinal cord infarction may present diverse aetiologies, with the cause remaining undetermined in many patients. Long-term functional prognosis is poor, and depends on baseline characteristics and clinical presentation. MRI, and especially diffusion-weighted sequences, is useful for early diagnosis.

Primary spontaneous intracerebral hemorrhage in COVID-19 patients: differences among presentation patterns - A systematic review.

OBJECTIVE: The objective of this study was to determine if there are differences between the presentation patterns of hemorrhagic stroke (HS) associated to COVID-19. METHODS: It was performed a systematic search based on PRISMA guidelines of the cases reported in PUBMED of HS associated to SARS-CoV-2 infection and we added to this sample cases from our own hospital cohort. Patients in the database were separated by groups according to presentation symptoms: if they debuted with neurological symptoms or debuted with pulmonary symptoms. RESULTS: Seventy cases were included in the study. Patients that debuted with pulmonary symptoms accounted for 68.6% of the cases with an interval between the development of symptoms and the presentation of HS of 15.6 days. We found that the use of anticoagulants during hospitalization, multifocal image pattern, and the elevation of D-dimer, Ferritin, and lactate dehydrogenase levels were significantly associated with the group of pulmonary presentation, whereas the presence of hypertension during hospitalization, and a lower hemoglobin level was associated with the group of neurologic symptoms. CONCLUSION: Although HS associated with COVID-19 is a clinical entity with increasing evidence, it is necessary to establish that there are two forms of presentation with their own characteristics.

OBJETIVO: determinar si existen diferencias entre los patrones de presentación de hemorragia intracraneal asociada a COVID-19. PACIENTES Y MÉTODOS: Se realizó una búsqueda sistemática basada en la guía PRISMA de los casos reportados en PUBMED de hemorragia intracraneal asociados a infección por SARS-CoV-2 y se agregaron a esta muestra casos de nuestra propia cohorte hospitalaria. RESULTADOS: se incluyeron 70 casos. Los pacientes que debutaron con síntomas pulmonares representaron el 68.6% de los casos con un intervalo entre el desarrollo de los síntomas y la presentación de la hemorragia intracraneal de 15.6 días. Encontramos que el uso de anticoagulantes durante la hospitalización, el patrón de imagen multifocal y la elevación de los niveles de dímero D, ferritina y deshidrogenasa láctica se asociaron significativamente con el grupo de presentación pulmonar, mientras que la presencia de hipertensión durante la hospitalización, y un nivel de hemoglobina más bajo se asoció con el grupo que debutó con síntomas neurológicos. CONCLUSIÓN: si bien la hemorragia intracraneal asociada a COVID-19 es una entidad clínica con evidencia creciente, es necesario establecer que existen dos formas de presentación con características propias.

Caracterización de la morbilidad de la endarterectomía carotídea / Characterization of the morbidity of carotid endarterectomy

Introducción: El 80 por ciento de los accidentes cerebrovasculares resulta de tipo isquémico y al menos el 20-30 por ciento está provocado por estenosis de la arteria carótida extracraneal. La endarterectomía carotídea tiene como principal objetivo eliminar las placas de ateroma, que son fuentes de émbolos para el encéfalo, y mejorar el flujo sanguíneo a este órgano. Objetivo: Caracterizar la morbilidad de la endarterectomía carotídea en el Hospital General Docente "Enrique Cabrera" desde 2018 hasta 2021. Métodos: Se realizó un estudio de tipo descriptivo y corte transversal a 32 pacientes, a los cuales se les realizó endarterectomía carotídea. La recolección de los datos se efectuó mediante la revisión de historias clínicas. El período de estudio abarcó desde enero de 2018 hasta enero de 2021. Resultados: Predominó el sexo masculino (65,6 por ciento) y la media de edad fue de 68,8 años. Los factores de riesgo más frecuentes resultaron la hipertensión arterial y el tabaquismo con 75 por ciento y 65,6 por ciento, respectivamente. La enfermedad cerebrovascular con secuela mínima constituyó la forma clínica más frecuente en el 40,6 por ciento de los casos. Se encontró asociación estadísticamente significativa entre diabetes mellitus y formas clínicas, y entre enfermedad arterial periférica y la aparición de complicaciones. La carótida izquierda resultó la más afectada con 53 por ciento y el porcentaje de estenosis, entre 70 por ciento y 99 por ciento, se encontró en el 55,9 por ciento de los pacientes. Con mayor frecuencia se presentaron las complicaciones: lesión de nervios craneales (5,8 por ciento) y hematoma cervical (5,8 por ciento). La endarterectomía por eversión se realizó en el 97 por ciento de los casos. Conclusiones: Se demostró la seguridad y el éxito de la endarterectomía carotídea. La mayoría de los pacientes tuvo una evolución satisfactoria, y se presentaron escasas complicaciones y mortalidad nula(AU)

Introduction: 80 percent of strokes result in ischemic type and at least 20-30 percent are caused by stenosis of the extracranial carotid artery. Carotid endarterectomy has as its main objective to remove atheromatous plaques, which are sources of emboli for the brain, and improve blood flow to this organ. Objective: To characterize the morbidity of carotid endarterectomy at the "Enrique Cabrera" General Teaching Hospital from 2018 to 2021. Methods: A descriptive, cross-sectional study was conducted in 32 patients, who underwent carotid endarterectomy. Data collection was carried out by reviewing medical records. The study period spanned from January 2018 to January 2021. Results: The male sex predominated (65.6 percent) and the mean age was 68.8 years. The most frequent risk factors were high blood pressure and smoking with 75 percent and 65.6 percent, respectively. Cerebrovascular disease with minimal sequelae was the most frequent clinical form in 40.6 percent of cases. A statistically significant association was found between diabetes mellitus and clinical forms, and between peripheral arterial disease and the occurrence of complications. The left carotid was the most affected with 53 percent and the percentage of stenosis, between 70 percent and 99 percent, was found in 55.9 percent of patients. The following complications were the most common: cranial nerve injury (5.8 percent) and cervical hematoma (5.8 percent). Eversion endarterectomy was performed in 97 percent of cases. Conclusions: The safety and success of carotid endarterectomy were demonstrated. Most of the patients had a satisfactory evolution, and there were few complications and zero mortality(AU)

Evaluación de la incidencia y tendencia de la enfermedad cerebrovascular en la región sanitaria de Lleida (España) en el periodo 2010-2014 / Assessment of incidence and trends in cerebrovascular disease in the healthcare district of Lleida (Spain) in the period 2010-2014

ObjetivoDeterminar la incidencia de la enfermedad cerebrovascular (ECV) y su tendencia en el área sanitaria de Lleida.Material y métodosEstudio de cohortes de base poblacional que incluyó a toda la población del área sanitaria de Lleida (440.000 personas). Se utilizaron los listados del Conjunto Mínimo Básico de Datos (CMBD) de urgencias y de las altas hospitalarias en el periodo comprendido entre enero de 2010 y diciembre de 2014. Se seleccionaron todos los episodios de ictus. Se evaluaron las tasas brutas y las tasas estandarizadas por edad utilizando la población mundial como referencia. Se excluyeron aquellos casos sin confirmación diagnóstica por neuroimagen.ResultadosSe incluyeron 4.397 casos, de los cuales 1.617 (36,8%) fueron ≥ 80 años; 3.969 (90,3%) sujetos sufrieron un ictus isquémico, mientras que 1.741 (39,6%) casos correspondieron a mujeres. La tasa de incidencia cruda osciló entre los 192 (intervalo de confianza [IC] del 95%: 179-205) en 2012 y los 211 (IC 95%: 197-224) en 2013 casos cada 100.000 habitantes. Las tasas estandarizadas por edad oscilaron entre los 93 (IC 95%: 86-100) en 2012 y los 104 (IC 95%: 96-111) en 2013 casos por cada 100.000 habitantes. En todos los años, las tasas de incidencia fueron significativamente mayores entre los varones en comparación con las mujeres; y se incrementaron con la edad.ConclusionesEl impacto de la ECV en Lleida es equiparable a otras regiones europeas, pero que el envejecimiento de la población se traduce en una incidencia bruta elevada que se mantiene estable en los 5 años analizados. (AU)

ObjectivesThis study aimed to determine the incidence and trends of cerebrovascular disease (CVD) in the healthcare district of Lleida.Material and methodsWe performed a population-based prospective cohort study including the entire population of the healthcare district of Lleida (440 000 people). Information was gathered from the minimum basic data set from the emergency department and hospital discharges for the period from January 2010 to December 2014. All types of stroke were included. We evaluated crude and age-standardised rates using the world population as a reference. Patients without neuroimaging confirmation of the diagnosis were excluded.ResultsWe identified 4397 patients: 1617 (36.8%) were aged 80 years or over; 3969 (90.3%) presented ischaemic stroke, and 1741 (39.6%) were women. The crude incidence rate ranged from 192 (95% confidence interval [CI], 179-205) to 211 (95% CI, 197-224) cases per 100 000 population, in 2012 and 2013, respectively. Age-standardised rates ranged from 93 (95% CI, 86-100) to 104 (95% CI, 96-111) cases per 100 000 population, in 2012 and 2013, respectively. For all years, incidence rates increased with age, and were significantly higher among men than among women.ConclusionThe impact of CVD in Lleida is comparable to that observed in other European regions. However, population ageing induces a high crude incidence rate, which remained stable over the five-year study period. (AU)

Ictus isquémico por oclusión de la arteria basilar en una paciente puérpera con infección por SARS-CoV-2 / Ischaemic stroke due to basilar artery occlusion in a puerperal patient with SARS-CoV-2 infection

Introducción: La infección por coronavirus de tipo 2 (SARS-CoV-2), causante del síndrome respiratorio agudo grave (COVID-19), produce complicaciones tromboembólicas, incluyendo casos de enfermedad cerebrovascular aguda. Debido al estado de hipercoagulabilidad que acompaña al embarazo, el riesgo trombótico en estas pacientes puede ser especialmente relevante. Caso clínico: Presentamos el caso de una mujer de 41 años, gestante de 34 + 1 semanas, diagnosticada de neumonía intersticial bilateral, SARS-CoV-2. La paciente presentó insuficiencia respiratoria grave, por lo que se decidió la realización de una cesárea urgente y se trasladó a la unidad de cuidados intensivos. Durante su estancia en ésta, la paciente presentó un episodio brusco de disminución del nivel de consciencia, y se evidenció por angiorresonancia magnética una trombosis en la arteria vertebral izquierda y en la arteria basilar, con presencia de infarto isquémico agudo en ambos hemisferios cerebelosos y afectación bilateral del tronco del encéfalo. Conclusión: La enfermedad grave por el SARS-CoV-2 produce un estado protrombótico que se correlaciona con el pronóstico de la enfermedad. El último trimestre del embarazo y el puerperio son factores de riesgo protrombóticos conocidos. Las recomendaciones del manejo de anticoagulación en pacientes embarazadas con COVID-19 se basan en una evidencia limitada. Éste es el primer caso publicado en España de trombosis arterial cerebral en una paciente embarazada con infección por el SARS-CoV-2.(AU)

Introduction: Infection by coronavirus type 2, which is the cause of severe acute respiratory syndrome (SARS-CoV-2), gives rise to thromboembolic complications, including acute cerebrovascular disease. Due to the hypercoagulable state that accompanies pregnancy, the thrombotic risk in these patients may be particularly significant. Case report: We report the case of a 41-year-old woman, 34+1 weeks pregnant, diagnosed with bilateral interstitial pneumonia, caused by coronavirus disease 2019 (COVID-19). The patient presented with severe respiratory failure, and so the decision was made to perform an emergency caesarean section and she was transferred to the intensive care unit. During her stay in hospital, the patient suffered a sudden episode of decreased level of consciousness, and magnetic resonance angiography revealed thrombosis in the left vertebral artery and in the basilar artery, with the presence of acute ischaemic infarction in both cerebellar hemispheres and bilateral involvement of the brainstem. Conclusion: Severe SARS-CoV-2 disease results in a prothrombotic state that correlates with the prognosis of the disease. The last trimester of pregnancy and the puerperium are known prothrombotic risk factors. Recommendations for anticoagulation management in pregnant patients with COVID-19 are based on limited evidence. This is the first case to be published in Spain involving cerebral arterial thrombosis in a pregnant patient with SARS-CoV-2 infection.(AU)

Características clínicas de enfermedad vascular prematura en un área de salud / Clinical characteristics of premature cardiovascular disease in our health area

Introducción y objetivos La enfermedad cardiovascular sigue siendo la principal causa de mortalidad, pero se disponen de pocos datos en población joven. El objetivo de nuestro estudio fue conocer la incidencia y características clínicas de la enfermedad cardiovascular prematura en nuestra área de salud. Métodos Estudio trasversal de pacientes ingresados por episodio agudo de enfermedad cardiovascular prematura en un hospital de referencia durante 2018. Resultados Se detectó a 367 sujetos: 306 (83,4%) con enfermedad cardiovascular aterosclerótica. Casi la mitad (164, 44,7%) eran diabéticos, con hipercolesterolemia primaria o alto riesgo cardiovascular, y 84 (22,9%) tenían antecedentes personales de enfermedad cardiovascular. De entre aquellos con riesgo elevado o antecedentes (n=207), solo 47 sujetos tenían colesterol LDL en objetivo terapéutico. Conclusiones La mayoría de los sujetos con enfermedad cardiovascular prematura de nuestro estudio presentaron mayor riesgo cardiovascular del atribuible a su edad. El diagnóstico y el tratamiento intensivo de los factores de riesgo cardiovascular pueden prevenir la enfermedad cardiovascular en adultos jóvenes (AU)

Introduction and objectives Cardiovascular disease continues to be the main cause of mortality, but few data are available in the young population. The aim of our study was to know the incidence and clinical characteristics of premature cardiovascular disease in our health area. Methods Cross-sectional study of patients admitted for acute episode of premature cardiovascular disease in a referral hospital during 2018. Results We detected 367 subjects: 306 (83.4%) with atherosclerotic cardiovascular disease. Almost half (164, 44.7%) were diabetic, with primary hypercholesterolaemia or high cardiovascular risk, and 84 (22.9%) had a personal history of cardiovascular disease. Among those with elevated risk or history (n=207) only 47 subjects had LDL cholesterol at therapeutic target. Conclusions Most of the subjects with premature cardiovascular disease in our study had higher cardiovascular risk than attributable to their age. Intensive diagnosis and treatment of cardiovascular risk factors may prevent cardiovascular disease in young adults (AU)

Attention to acute cerebrovascular disease in Guipúzcoa: description of the results of a reference hospital in a centralized care model.

INTRODUCTION: In the last 15 years, considerable improvements have been made in acute stroke care in Guipuzkoa, including the implementation of a centralised care model at Hospital Universitario Donostia (HUD), improved coordination between professionals, early detection campaigns, new treatments, a stroke unit, and specific rehabilitation. The aim of this work is to describe the results of a reference hospital (HUD) in a centralised care model. MATERIAL AND METHODS: We performed a retrospective observational study of a sample of patients discharged between August and December 2015 from the HUD with a diagnosis of acute stroke (ICD-9-CM codes 430-436, except 433.10). We review patients' baseline characteristics, acute-phase care, and functional outcomes and mortality at discharge and at one year. RESULTS AND DISCUSSION: We identified 536 patients, with a mean age of 73.6 years and a high comorbidity rate. Ischaemic stroke accounted for 64.8% of patients, followed by haemorrhagic stroke (20%) and transient ischaemic attack (14.8%). A total of 53% of patients were attended in < 6 hours, with code stroke being activated in 37.1%; 52.2% of patients were admitted to the stroke unit. Intravenous therapy was administered to 8.3% of patients with ischaemic stroke, and 9.5% underwent mechanical thrombectomy. Surgery was performed in 12.1% patients with haemorrhagic stroke. Rehabilitation was started at hospital in 56% of patients, and 39.6% continued with this treatment at discharge. Mortality was 13.8% at discharge and 25.9% at one year (ischaemic stroke, 25.3%; haemorrhagic stroke, 47.5%); these figures are lower than those previously reported in Guipuzkoa. At one year, 62.5% of patients had a Barthel Index score of 95-100, and 50% a modified Rankin Scale score of 0-2. CONCLUSIONS: After the strategic changes implemented in acute stroke care in Guipuzkoa, including the centralisation of the acute stroke care model, mortality rates at discharge and at one year are lower in 2015 than the previously reported rates, with similar rates of independence. These results are consistent with those published by other Spanish and European centres.
