Fibrilación auricular no valvular en pacientes en diálisis peritoneal: prevalencia, tratamiento y profesionales implicados / Non-valvular atrial fibrillation in patients on peritoneal dialysis: prevalence, treatment and professionals involved

La fibrilación auricular (FA) es la arritmia crónica más frecuente en pacientes con enfermedad renal crónica (ERC). La anticoagulación oral con antagonistas de la vitamina K (AVK) y actualmente los anticoagulantes orales de acción directa (ACOD) han sido el pilar fundamental para la prevención de eventos tromboembólicos. Sin embargo, no existen ensayos clínicos aleatorizados de su perfil riesgo-beneficio en pacientes con ERC estadio 5 en diálisis peritoneal (DP) y son pocas las evidencias en la literatura sobre esta población. El objetivo del estudio fue conocer la prevalencia, tratamiento y profesionales implicados en el manejo de la FA en DP en nuestro entorno mediante el análisis descriptivo de una encuesta enviada a diferentes unidades de DP de España. Se incluyeron en el estudio 1.403 pacientes en programa de DP, de los cuales 186 (13,2%) presentaban FA no valvular (FANV). Además, observamos que la valoración de los scores para el inicio del tratamiento anticoagulante la realizaba mayoritariamente el cardiólogo (60% de los centros), así como la prescripción de anticoagulación (cardiólogo 47% o en conjunto con el nefrólogo 43%). En conclusión, los pacientes en DP presentan una notable prevalencia de FANV. Reciben frecuentemente anticoagulación oral (ACO) con AVK, así como con ACOD. Los datos obtenidos respecto a las escalas utilizadas para la valoración de riesgo tromboembólico y de sangrado, tratamiento e implicación por parte de Nefrología indican que existe una necesidad de formación e involucramiento del nefrólogo en esta patología.(AU)

Atrial fibrillation is the most frequent chronic arrhythmia in patients with chronic kidney disease. Oral anticoagulation with vitamin K antagonists and now direct oral anticoagulants have been and are the fundamental pillar for the prevention of thromboembolic events. However, there are no randomized clinical trials on the risk-benefit profile of oral anticoagulation in patients with chronic kidney disease stage 5 on peritoneal dialysis and there is little evidence in the literature in this population. The objective of our study was to know the prevalence, treatment and professionals involved in the management of atrial fibrillation in peritoneal dialysis patients. For this purpose, we performed a descriptive analysis through a survey sent to different peritoneal dialysis units in Spain. A total of 1403 patients on peritoneal dialysis were included in the study, of whom 186 (13.2%) had non-valvular atrial fibrillation. In addition, the assessment of the scores of thromboembolic and bleeding risks for the indication of oral anticoagulation was mainly carried out by the cardiologist (60% of the units), as well as its prescription (cardiologist 47% in consensus with the nephrologist 43%). In summary, patients on peritoneal dialysis have a remarkable prevalence of non-valvular atrial fibrillation. Patients frequently receive oral anticoagulation with vitamin K antagonists, as well as direct oral anticoagulants. The data obtained regarding the scales used for the assessment of thromboembolic and bleeding risk, treatment and involvement by Nephrology indicates that there is a need for training and involvement of the nephrologist in this pathology.(AU)

Tiempos de cateterismo y uso de pretratamiento antiagregante plaquetario en pacientes con SCASEST en España / Timing of coronary angiography and use of antiplatelet pretreatment in patients with NSTEACS in Spain

Introducción y objetivos El momento óptimo para un cateterismo en el síndrome coronario agudo sin elevación del segmento ST (SCASEST) y la necesidad de pretratamiento son motivo de controversia. El objetivo principal del registro IMPACT-TIMING-GO es conocer el porcentaje de pacientes examinados con una coronariografía precoz (0-24 h) y que no recibieron doble antiagregación plaquetaria antes del cateterismo (estrategia sin pretratamiento) en España. Métodos Estudio observacional, prospectivo y multicéntrico, que incluyó a pacientes consecutivos con diagnóstico de SCASEST sometidos a cateterismo en los que se evidenció enfermedad coronaria ateroesclerótica causal. Resultados Entre abril y mayo de 2022 se incluyó a 1.021 pacientes (media de edad, 67±12 años; el 23,6% mujeres). El 86,8% de los pacientes cumplían criterios de alto riesgo (elevación de troponina, cambios electrocardiográficos o puntuación GRACE>140); sin embargo, únicamente el 37,8% se sometió a una estrategia invasiva precoz, y el 30,3% no recibió pretratamiento. Globalmente, solo el 13,6% de los pacientes se sometieron a una estrategia invasiva precoz sin un segundo antiagregante plaquetario, y la estrategia diferida con pretratamiento fue la más utilizada (46%). Durante el ingreso, 9 pacientes (0,9%) fallecieron y 34 (3,3%) presentaron una hemorragia grave. Conclusiones En España, solo el 13,6% de los pacientes con SCASEST sometidos a cateterismo reciben una estrategia invasiva precoz sin pretratamiento. La incidencia de eventos cardiovasculares y hemorragias graves en el ingreso es baja. (AU)

Introduction and objectives The optimal timing of coronary angiography in patients admitted with non–ST-segment elevation acute coronary syndrome (NSTEACS) as well as the need for pretreatment are controversial. The main objective of the IMPACT-TIMING-GO registry was to assess the proportion of patients undergoing an early invasive strategy (0-24hours) without dual antiplatelet therapy (no pretreatment strategy) in Spain. Methods This observational, prospective, and multicenter study included consecutive patients with NSTEACS who underwent coronary angiography that identified a culprit lesion. Results Between April and May 2022, we included 1021 patients diagnosed with NSTEACS, with a mean age of 67±12 years (23.6% women). A total of 87% of the patients were deemed at high risk (elevated troponin; electrocardiogram changes; GRACE score>140) but only 37.8% underwent an early invasive strategy, and 30.3% did not receive pretreatment. Overall, 13.6% of the patients underwent an early invasive strategy without pretreatment, while the most frequent strategy was a deferred angiography under antiplatelet pretreatment (46%). During admission, 9 patients (0.9%) died, while major bleeding occurred in 34 (3.3%). Conclusions In Spain, only 13.6% of patients with NSTEACS undergoing coronary angiography received an early invasive strategy without pretreatment. The incidence of cardiovascular and severe bleeding events during admission was low. (AU)

Riesgo de hemorragia cerebral en el traumatismo craneal leve y tratamiento antitrombótico / Risk of cerebral hemorrhage in mild traumatic brain injury and antithrombotic treatment

Objetivo El tiempo de observación en el traumatismo craneoencefálico leve (TCEL) es controvertido. Nuestro objetivo se basó en evaluar el riesgo de complicaciones neurológicas en el TCEL con y sin tratamiento antitrombótico. Método Evaluamos retrospectivamente los pacientes con TCEL atendidos en urgencias durante 3 años. Consideramos TCEL aquellos con Glasgow ≥13 al ingreso. Se realizó una TC craneal en todos los casos con >1 factor de riesgo al ingreso y a las 24h en aquellos con deterioro neurológico o TC craneal inicial patológica. Se revisó retrospectivamente las complicaciones en los siguientes 3 meses. Resultados Evaluamos 907 pacientes con una edad media de 73±19 años. El 91% presentaron factores de riesgo, con un 60% en tratamiento antitrombótico. Detectamos un 11% de hemorragia cerebral inicial, 0,4% a las 24h y ningún caso a los 3 meses. El tratamiento antitrombótico no se asoció con incremento de riesgo de hemorragia cerebral (9,9 con vs. 11,9% sin tratamiento; p=0,3). El 39% de las hemorragias presentaron síntomas neurológicos (18% amnesia postraumática, 12% cefalea, 8% vómitos, 1% convulsiones), siendo en un 78,4% síntomas leves. De las 4 hemorragias detectadas a las 24h, 3 fueron asintomáticas y un caso emporó la cefalea inicial. Ningún paciente asintomático sin lesión en la TC craneal inicial presentó clínica a las 24h. Conclusiones Nuestro estudio sugiere que los pacientes con TCEL asintomáticos, sin lesión en la TC craneal inicial no precisarían periodo de observación ni TC craneal de control, independientemente del tratamiento antitrombótico o nivel de INR (AU)

Introduction The observation time in mild traumatic brain injury (mTBI) is controversial. Our aim was to assess the risk of neurological complications in mTBI with and without antithrombotic treatment. Method We retrospectively evaluated patients with mTBI seen in the emergency room for 3 years. We considered MTBI those with Glasgow ≥13 at admission. A cranial CT was performed in all cases with >1 risk factor at admission and at 24h in those with neurological impairment or initial pathological cranial CT. Complications in the following 3 months were retrospectively reviewed. Results We evaluated 907 patients with a mean age of 73±19 years. Ninety-one percent presented risk factors, with 60% on antithrombotic treatment. We detected 11% of initial brain hemorrhage, 0.4% at 24h, and no cases at 3 months. Antithrombotic treatment was not associated with an increased risk of brain hemorrhage (9.9% with vs. 11.9% without treatment, P=.3). 39% of the hemorrhages presented neurological symptoms (18% post-traumatic amnesia, 12% headache, 8% vomiting, 1% seizures), with 78.4% having mild symptoms. Of the 4 hemorrhages detected at 24h, 3 were asymptomatic and one case that worsened the initial headache. No asymptomatic patient without lesion on initial clinical cranial CT presented at 24h. Conclusions Our study suggests that patients with asymptomatic mTBI, without a lesion on the initial cranial CT, would not require the observation period or CT control regardless of antithrombotic treatment or INR level (AU)

Registro observacional prospectivo sobre la utilización del tratamiento antitrombótico durante el periodo perioperatorio y periprocedimiento en el «mundo real»: estudio REQXAA / Prospective observational registry of perioperative and periprocedural management of antithrombotic therapy in “real world”: the REQXAA study

Introducción y objetivos: Existe escasa evidencia acerca del impacto de las actuales recomendaciones sobre la utilización del tratamiento antitrombótico durante el periodo perioperatorio y periprocedimiento en el «mundo real». El objetivo de este estudio es analizar la utilización de los fármacos antitrombóticos en una población de pacientes que van a someterse a una cirugía/procedimiento, así como evaluar la implicación que tiene su retirada o mantenimiento en la incidencia de eventos adversos trombóticos y/o hemorrágicos. Métodos: Estudio observacional prospectivo, multicéntrico y multiespecialidad de pacientes en tratamiento antitrombótico que precisen alguna intervención. El objetivo principal fue la incidencia de eventos trombóticos y hemorrágicos a 30 días en función del uso periintervención de los fármacos antitrombóticos. Resultados: Se incluyó a un total de 1.266 pacientes (el 63,5% varones; media de edad, 72,6 años). El 48,6% de ellos se encontraban anticoagulados (la mayoría por fibrilación auricular; CHA2DS2-VASC, 3,7) y el 53,3%, antiagregados, con mayor frecuencia por cardiopatía isquémica. El 66,7% tenía un riesgo isquémico bajo y el 51,9%, un riesgo hemorrágico de la intervención bajo. El tratamiento antitrombótico periprocedimiento según las recomendaciones actuales fue idóneo únicamente en el 57,3% de los casos. Los pacientes con un uso inadecuado de los fármacos antitrombóticos periprocedimiento presentaron una incidencia de eventos adversos trombóticos y hemorrágicos significativamente mayor. Conclusiones: A pesar de las recomendaciones actuales acerca de la utilización de fármacos antitrombóticos en el periodo perioperatorio/periprocedimiento, su implementación en el «mundo real» continúa siendo baja. Un uso inadecuado se asocia con un aumento de la incidencia de eventos adversos, tanto trombóticos como hemorrágicos.(AU)

Introduction and objectives: There is scarce real-world evidence on the management of perioperative antithrombotic treatment according to current recommendations. The aim of this study was to analyze the management of antithrombotic treatment in patients undergoing surgery or another invasive intervention and to assess the consequences of this management on the occurrence thrombotic or bleeding events. Methods: This prospective, observational, multicenter and multispecialty study analyzed patients receiving antithrombotic therapy who underwent surgery or another invasive intervention. The primary endpoint was defined as the incidence of adverse (thrombotic and/or hemorrhagic) events after 30 days of follow-up with respect to management of perioperative antithrombotic drugs. Results: We included 1266 patients (male: 63.5%; mean age 72.6 years). Nearly half of the patients (48.6%) were under chronic anticoagulation therapy (mainly for atrial fibrillation; CHA2DS2-VASC: 3.7), while 53.3% of the patients were under chronic antiplatelet therapy (mainly for coronary artery disease). Low ischemic and hemorrhagic risk was found in 66.7% and 51.9%, respectively. Antithrombotic therapy management was in line with current recommendations in only 57.3% of the patients. Inappropriate management of antithrombotic therapy was an independent risk factor for both thrombotic and hemorrhagic events. Conclusions: The implementation of recommendations on the perioperative/periprocedural management of antithrombotic therapy in real-world patients is poor. Inappropriate management of antithrombotic treatment is associated with an increase in both thrombotic and hemorrhagic events.(AU)

Actualización en el manejo perioperatorio de antiagregantes y anticoagulantes en cirugía oftalmológica / Update on the perioperative management of antiplatelets and anticoagulants in ophthalmic surgery

Introducción Los fármacos anticoagulantes y antiagregantes son ampliamente utilizados con indicaciones médicas diversas. Por tanto, hay cada vez más pacientes que precisan una cirugía oftalmológica programada y se encuentran en tratamiento con esta medicación. El conocimiento de sus implicaciones y su correcto abordaje perioperatorio permite reducir complicaciones quirúrgicas y efectos adversos en los pacientes. En muchas ocasiones no hay una recomendación clara sobre cómo actuar con estas familias de fármacos en determinadas cirugías. Objetivo Realizar una revisión bibliográfica sobre el manejo perioperatorio de los antiagregantes y anticoagulantes en cirugía oftalmológica. Material y métodos Se revisan los protocolos y la literatura existente acerca del empleo de dichos fármacos en diversas cirugías oftálmicas: catarata, vítreo-retina, glaucoma, cirugía oculoplástica y orbitaria y estrabismo. Resultados Se referencian guías clínicas y estudios que recogen las recomendaciones acerca del mantenimiento o suspensión de antiagregantes y anticoagulantes en diferentes campos quirúrgicos de la oftalmología. Conclusiones En la cirugía de catarata mediante facoemulsificación con anestesia tópica existe evidencia de que el mantenimiento de la medicación antitrombótica es seguro. En el resto de las cirugías oftalmológicas se debería actuar en función del riesgo hemorrágico y trombótico que presente la cirugía y el paciente para su correcta utilización. En casos complejos, se recomienda un abordaje multidisciplinar. Serían necesarios más estudios para la confección de guías clínicas que facilitasen el manejo perioperatorio de estos fármacos en cirugía oftalmológica (AU)

Introduction Anti-thrombotic drugs (antiplatelets and anticoagulants) are widely used for different clinical reasons. This means that there are an increasing number of patients undergoing elective ophthalmic surgery that are being treated with these drugs. A better knowledge of their implications and their peri-operative use may help to prevent surgical and secondary adverse events. There is often no firm recommendation on how to manage certain drugs in certain surgeries. Objective To review the recommendations in the scientific literature as regards managing anti-thrombotic agents during the peri-operative period of ophthalmic surgery. Material and methods A review was made of the relevant guidelines and studies using an antiplatelet and anticoagulant drugs approach for cataract, vitreo-retinal, glaucoma, oculoplastic, and strabismus surgeries. Results Recommendations about whether to continue or discontinue anti-thrombotic drugs in the peri-operative period of different ophthalmic surgical fields are presented. Conclusions There are only firm recommendations of maintaining anti-thrombotic drugs as regards cataract surgery using phacoemulsification with topical anaesthesia. In other surgical fields, ophthalmologists should balance the risk of thromboembolic events and risks of haemorrhagic complications in order to carry out a proper management. A multi-disciplinary approach is recommended for complex cases. Additional studies should be performed to better characterise the peri-operative use of anti-thrombotic agents in order to prepare clinical guidelines for ophthalmic surgery (AU)

Novedades de las guías de la Sociedad Europea de Cardiología 2020 sobre manejo del síndrome coronario agudo sin elevación persistente del segmento ST / News from the European Society of Cardiology 2020 guidelines on the management of acute coronary syndrome without persistent ST-segment elevation / Novidades da Sociedade Europeia de Cardiologia 2020 diretrizes sobre o tratamento da síndrome coronariana aguda sem elevação persistente do segmento ST

Las enfermedades cardiovasculares representan la primera causa de muerte en el mundo. El manejo de los síndromes coronarios ha avanzado formidablemente en los últimos 50 años, reduciendo el riesgo isquémico, a expensas del consiguiente aumento del riesgo hemorrágico. La Sociedad Europea de Cardiología publicó en el año 2020 la guía sobre el manejo de síndrome coronario agudo sin elevación del segmento ST, donde se destacan cambios en los algoritmos de estratificación de riesgo y la terapia antiplaquetaria y anticoagulante como dos de los aspectos principales. En el presente editorial se resumen las principales novedades publicadas en este documento.

Cardiovascular disease is the leading cause of death worldwide. The management of coronary syndromes has advanced dramatically in the last 50 years, reducing ischemic risk, but observing an increase in bleeding risk. The European Society of Cardiology published in 2020 the guideline on the management of acute coronary syndrome without ST-segment elevation, where changes in risk stratification algorithms and antiplatelet and anticoagulant therapy are highlighted as two of the main aspects. This editorial summarizes the main developments published in this document.

A doença cardiovascular é a principal causa de morte em todo o mundo. O manejo das síndromes coronarianas avançou dramaticamente nos últimos 50 anos, reduzindo o risco isquêmico, mas observando um aumento no risco de sangramento. A Sociedade Europeia de Cardiologia publicou em 2020 a diretriz sobre o manejo da síndrome coronariana aguda sem supradesnivelamento do segmento ST, onde as alterações nos algoritmos de estratificação de risco e na terapia antiplaquetária e anticoagulante são destacadas como dois dos principais aspectos. Este editorial resume os principais desenvolvimentos publicados neste documento.

Optimización de la detección de fibrilación auricular subclínica tras un ESUS / Optimizing the detection of subclinical atrial fibrillation after ESUS

Introducción: Se ha estimado que aproximadamente el 20% de los ictus isquémicos tiene un origen cardioembólico y que no se detecta la causa o que puede haber más de una en el 9-25% de ellos. Un proceso diagnóstico adecuado de ESUS permitiría optimizar el tratamiento antitrombótico. Objetivo: Revisión bibliográfica sobre la evidencia disponible acerca de la mejor aproximación diagnóstica y terapéutica de los pacientes con ESUS y cómo optimizar la detección de la posible fibrilación auricular como causa. Desarrollo: Se realizó una búsqueda a través de PubMed (MEDLINE), mediante los términos MeSH [ESUS] + [atrial fibrillation] + [diagnosis] + [treatment]. Se seleccionaron publicaciones originales de ensayos clínicos, y estudios prospectivos, retrospectivos y de revisión. Conclusiones: La detección de fibrilación auricular tras un ESUS es fundamental para optimizar el tratamiento. Sin embargo, no todos los pacientes tienen el mismo riesgo de presentar fibrilación auricular silente. Existen determinados factores que incrementan este riesgo (dilatación de la aurícula izquierda, edad avanzada, extrasistolia supraventricular frecuente). En estos pacientes, una monitorización más prolongada permitiría aumentar las posibilidades de diagnóstico de la fibrilación auricular y, por lo tanto, beneficiarse, en mayor medida, del tratamiento anticoagulante para evitar ictus recurrentes.(AU)

Introduction: It has been estimated that approximately 20% of ischemic strokes have a cardioembolic origin and the cause is not detected or there are more than one in 9-25% of ischemic strokes. An adequate diagnostic approach of ESUS would allow an optimization of antithrombotic treatment. Objective: Narrative update about the available evidence on the best diagnostic and therapeutic approach among patients with ESUS and how to optimize the detection of atrial fibrillation as a potential cause is reviewed. Development: A search was conducted on PubMed (MEDLINE), using the MeSH terms [ESUS] + [atrial fibrillation] + [diagnosis] + [treatment]. Original data from clinical trials, prospective and retrospective studies and reviews were selected. Conclusions: The detection of atrial fibrillation after ESUS is mandatory to optimize the treatment. However, not all patients have the same risk of developing silent atrial fibrillation. There are some factors that increase this risk (left atrium enlargement, elderly, frequent premature supraventricular complexes). In these patients, a more prolonged monitorization could increase the possibility of detecting atrial fibrillation, and consequently, to benefit more from anticoagulant treatment.(AU)

Obstrucción arterial y venosa retiniana como primera manifestación de un síndrome de anticuerpos antifosfolípidos / Retinal arterial and venous obstruction as the first manifestation of an antiphospholipid antibody syndrome

Mujer de 34 años sin antecedentes de interés que acudió por disminución de visión del ojo derecho. El examen reveló una obstrucción de vena central de la retina y de la arteria ciliorretiniana. Dada la edad de la paciente se consultó con cardiología y hematología para descartar un estado de hipercoagulabilidad y patología tromboembólica. La analítica fue positiva para los anticuerpos anticardiolipina y antifosfolípidos. Se diagnosticó de un síndrome de anticuerpos antifosfolípidos. Se inició tratamiento antiagregante, anticoagulante y corticoideo. Discusión El síndrome antifosfolípido puede causar trombosis en cualquier órgano. La afectación de los vasos retinianos puede ser la primera manifestación. Su diagnóstico es importante para evitar fenómenos trombóticos recurrentes. (AU)

A 34 year-old woman presented with decrease in visual acuity in her right eye (RE). Her past medical history was unremarkable. Dilated fundus examination revealed a central venous occlusion and an obstruction of the cilioretinal artery. Given the patient age, a cardiology and haematology screen were obtained to rule out hypercoagulation disorders and thromboembolic disease. Antiplatelet, anticoagulant, and corticosteroid therapy were started. The laboratory result was positive for anticardiolipin and antiphospholipid antibody. A diagnosis of antiphospholipid syndrome (APS) was made. Discussion Antiphospholipid syndrome may cause thrombosis in any organ. The involvement of the retinal vessels may be the first manifestation of this entity. This diagnosis is important to prevent recurrent thrombotic events. (AU)

Control de anemia y transfusión en el manejo perioperatorio de pacientes con fractura de cadera. Estudio de cohorte longitudinal / Control of anemia and transfusion in perioperative management of patients with hip fracture. A Cohort Study

Introducción El objetivo del estudio es pormenorizar los factores asociados a fracturas de cadera, prestando especial atención a las necesidades de transfusión de hemoderivados y sus factores de riesgo, así como su modificación a través del tratamiento preoperatorio mediante la administración de hierro intravenoso. Materiales y métodos Estudio observacional prospectivo de 119 pacientes ingresados por fractura de cadera. Descripción detallada del protocolo para la optimización prequirúgica de estos pacientes. Se recopilaron datos epidemiológicos, valores analíticos, así como datos acerca de la administración de hierro intravenoso y necesidad de transfusión. Resultados El 31,09% de los pacientes se encontraban antiagregados y el 21,85% estaban anticoagulados en el momento de la admisión. La hemoglobina media al ingreso fue de 12,5g/dl. El 43,2% se transfundieron durante la estancia hospitalaria. En el análisis de los factores de riesgo para la transfusión demostramos estadísticamente que tanto la hemoglobina al ingreso (p<0.001), como los diagnósticos previos de anemia crónica, hipertensión arterial e insuficiencia renal, tienen una relación con la necesidad de transfusión intrahospitalaria. Encontramos una relación estadísticamente significativa entre la administración de hierro y la cantidad de concentrados de hematíes trasfundidos (p<0.005). Los requerimientos de transfusión sanguínea fueron mayores en las fracturas extracapsulares que en las intracapsulares (p=0,024). Discusión Los pacientes con fractura de cadera presentan frecuentemente bajos niveles de hemoglobina al ingreso, así como comorbilidades y tratamientos que predisponen al desarrollo de anemia perioperatoria. La optimización preoperatoria de estos pacientes mediante la administración de hierro intravenoso podría reducir las necesidades transfusionales.

Background Aim of the study is to describe the elements associated with hip fractures about needs for transfusion of blood products and their risk factors, as well as their modification through preoperative treatment through the administration of intravenous iron. Material and methods A Cohort study of 119 patients admitted for hip fracture was conducted. Detailed description of the protocol for the pre-surgical optimization of these patients, epidemiological data, analytical values, as well as data on intravenous iron administration and need for transfusion were collected. Results 31.09% of the patients were using platelet aggregation inhibitors and 21.85% were were using anticoagulants at the time of admission. The mean hemoglobin on admission was 12.5g / dl. 43.2% were transfused during the hospital stay. In the analysis of risk factors for transfusion, we statistically demonstrated that both hemoglobin on admission (p <0.001), as well as previous diagnoses of chronic anemia, arterial hypertension, and renal failure, are related to the need for intra-hospital transfusion. We found a statistically significant relationship between iron administration and the amount of packed red blood cells transfused (p <0.005). Blood transfusion requirements were higher in extra-capsular than in intra-capsular fractures (p=0.024). Discussion Patients with hip fracture frequently present low hemoglobin levels upon admission, as well as comorbidities and treatments that predispose to the development of perioperative anemia. Preoperative optimization of these patients by administering intravenous iron could reduce transfusion requirements.

[Impact of antithrombotic treatment and geriatric syndromes in octogenarians with atrial fibrillation and ischaemic heart disease. Atrial Fibrillation and Ischemic Heart Disease in the Elderly]. / Impacto del tratamiento antitrombótico y los síndromes geriátricos en octogenarios con fibrilación auricular y cardiopatía isquémica. Fibrilación Auricular y Cardiopatía Isquémica en Longevos (FACIL).

BACKGROUND AND OBJECTIVES: The prevalence of atrial fibrillation (AF) and ischaemic heart disease (IHC) increases with age. They coexist in up to 20% of octogenarian patients, a situation that poses a therapeutic challenge. Trials that have addressed this scenario, which included a low percentage of octogenarians, showed that double therapy (single antiplatelet + anticoagulation) compared to triple therapy (double antiplatelet + anticoagulation) was associated with less bleeding events, especially with direct oral anticoagulants. These studies did not have sufficient power to detect differences in ischaemic events. On the other hand, prevalent characteristics in the elderly, such as geriatric syndromes, were not assessed in these studies, and are not usually evaluated in clinical practice. Accordingly, their prognostic impact remains unknown in this clinical context. METHODS: Observational, prospective, and multicentre study that will include patients ≥ 80 years with AF and IHC in Spain. Baseline characteristics and geriatric syndromes will be assessed, as well as the choice of antithrombotic treatment. The primary endpoint is cardiovascular and overall mortality at one and three years follow-up. RESULTS: This study will assess both characteristics and prognosis of octogenarian patients with AF and IHC in Spain, the factors involved in the choice of antithrombotic treatment, and the incidence of ischaemic and haemorrhagic events during the short- and long-term follow-up. CONCLUSION: This study will contribute to improve the knowledge in terms of safety and efficacy of the different therapeutic options in older patients with AF and IHC, as well as their prognostic impact.

Sex-specific differences in antithrombotic therapy and prognosis in patients with acute coronary syndrome treated with stent.

Aims and objective: Impact of sex-related differences in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention and treated with new P2Y12 inhibitors is not adequately characterised. We aimed to analyse gender-based differences in dual antiplatelet therapy, and adverse cardiovascular events and bleeding. Materials and methods: Prospective-observational study of the consecutive ACS patients treated with stent from July 2016 to January 2016, with a follow-up of 1 year. Results: We examined 283 patients, 75 (26.5%) women and 208 (73.5%) men. Women were older than men (71 ± 13 vs. 66,5 ± 13 years). There were 44% of women and 52% of men presenting with ST-elevation ACS (p = 0.21). Women had a higher bleeding risk (CRUSADE), without differences in the ischaemic risk (GRACE and TIMI). More women were treated with drug-eluting stent (88.9 vs. 75.5%, p = 0.04). There was a lower rate of ticagrelor prescription in women (42.6 vs. 50.9%, p = 0.29), in favour of clopidogrel. No differences were observed in prasugrel prescription. No significant differences were observed after a year of follow up, but women had a tendency towards lower mortality (1.4 vs. 6.7%, p = 0.19) and higher bleeding rates (23.3 vs. 17.4%, p = 0.27). Conclusions: In our study of patients presenting with ACS treated with stent, clopidogrel was preferred in women, whereas ticagrelor was the most frequent prescription in men. No significant differences were noted in clinical outcomes, but women experienced a tendency towards less mortality and more bleeding events.

Antecedentes y objetivo: El interés sobre la influencia del sexo en pacientes con síndrome coronario agudo (SCA) tratados con stent y nuevos antiagregantes inhibidores de P2Y12 en la práctica clínica es creciente. Se analizan las diferencias en función del sexo en el tratamiento con doble antiagregación plaquetaria (DAPT) y los eventos adversos isquémicos y hemorrágicos. Materiales y métodos: Estudio prospectivo de pacientes consecutivos con diagnóstico de SCA tratados con stent coronario desde julio de 2015 hasta enero de 2016. Resultados: De un total de 283 pacientes incluidos, 75 (26.5%) correspondió a mujeres y 208 (73.5%) a hombres. La edad media fue de 71 ± 13 y 66.5 ± 13 años, respectivamente. Un 44% de mujeres se presentó como SCA con elevación del segmento ST contra un 52.4 de los hombres, p = 0.21. Las mujeres mostraron un mayor riesgo de sangrado (CRUSADE), sin diferencias en el riesgo isquémico (GRACE y TIMI). Se usaron stents farmacoactivos con más frecuencia en mujeres (88.9 vs. 75.5%, p = 0.04). Se observó una tendencia de menor prescripción del ticagrelor en mujeres (42.6 vs. 50.9%, p = 0.29) en favor de un mayor uso del clopidogrel. No se identificaron diferencias en cuanto a la prescripción del prasugrel. Las mujeres presentaron al año una menor mortalidad (1.4 vs. 6.7%, p = 0.19), aunque mayor sangrado (23.3 vs. 17.4%, p = 0.27). Conclusiones: En este estudio de pacientes consecutivos con SCA tratados con stent se registró una mayor prescripción de clopidogrel en las mujeres que en los hombres. Las mujeres presentaron una menor incidencia anual de mortalidad, pero mayor sangrado en comparación con los hombres, no significativo.

The role of aspirin as antiaggregant therapy in primary prevention. An update. / Papel de la Aspirina® como tratamiento antiagregante en prevención primaria. Puesta al día.

Aspirin indication in primary prevention has been questioned in the last ten years due to the publication of several trials with neutral outcomes. In the last year, three research studies discussed in this review (ASCEND, ARRIVE, ASPREE) have weighed the benefit (cardiovascular events reduction) against the adverse effects (especially bleeding) in several situations such as general population with moderate cardiovascular risk, diabetics and elderly population. This review performs a detailed analysis of these trials and it also comments on a recent metanalysis that includes these projects along with others undertaken in the last 30 years. In addition, the current position of aspirin in primary prevention is established based on the latest evidence reviewed.

Doble terapia antiagregante en pacientes con accidente cerebrovascular isquémico agudo: Recomendación del grupo CIERTO / Dual antiplatelet therapy for secondary stroke prevention in patients with acute ischemic stroke. CIERTO group recommendation

El inicio precoz del tratamiento con antiagregantes plaquetarios es considerado el estándar de cuidado para pacientes con accidente cerebrovascular isquémico agudo. Distintos esquemas de antiagregación se han comparado con resultados que sugieren que la combinación de múltiples antiagregantes se asocian a menor riesgo de recurrencia de accidente cerebrovascular (ACV) pero a expensas de un aumento en el riesgo de sangrado, lo que a largo plazo termina opacando dichos beneficos. Sin embargo, considerando que el riesgo de recurrencia de ACV es mayor en el periodo inmediato al evento, la indicación de doble tratamiento antiagregante por tiempos limitados podría asociarse a beneficios relevantes. Con este concepto, se realizó una revisión sistemática rápida con el objetivo de evaluar el efecto del tratamiento con doble antiagregación por un periodo corto intentando maximizar el beneficio y reducir al mínimo el riesgo de sangrado. Se incluyeron todos los estudios primarios identificados en los que se comparó un esquema de doble antiagregación, iniciado en el periodo agudo del evento índice (ACV o accidente isquémico transitorio - AIT), contra un esquema de simple antiagregación. El cuerpo de la evidencia mostró que la intervención (doble antiagregación) reduce el riesgo de recurrencia de ACV y probablemente se asocie a un aumento marginal en el riesgo de sangrado mayor. Sugerimos indicar doble esquema antiplaquetario para el tratamiento inicial de pacientes con ACV isquémico menor (Score NIH < o igual a 3 o AIT).

One of the main pillars of acute ischemic stroke management is antiplatelet therapy. Different treatment schemes have been compared, suggesting that the combination of multiple antiplatelet drugs is associated with a reduced risk of stroke recurrence. However, it has also been associated with an increased risk of bleeding complications which, in the long term, surpass the mentioned benefits. However, considering that most stroke recurrences occur i n the short term, a time limited double antiplatelet scheme could result in significant benefits to patients with acute ischemic stroke. On this basis, we conducted a rapid systematic review of the literature in order to evaluate the effects of a short-term double antiplatelet therapy both on stroke recurrence and complications. All trials comparing double versus single antiplatelet therapy in patients with acute ischemic stroke were included. Results showed that double therapy reduces recurrence risk but probably marginally increases major bleeding complications. We suggest double antiplatelet therapy for the initial management of patients with minor (Score NIH < or equal to 3 or transient isquemic attack -TIA) acute ischemic stroke.
