ABSTRACT

This review explores gender disparities in cardiac electrophysiology, highlighting differences in the electrical activity of the heart between men and women. It emphasizes the importance of understanding these variances for correct diagnosis and effective treatment of cardiac arrhythmias. Women show distinct cardiac characteristics influenced by sex hormones, affecting their susceptibility to various arrhythmias. The manuscript covers the classification, mechanisms, and management of arrhythmias in women, considering factors such as pregnancy and menopause. By addressing these gender-specific nuances, it aims to improve healthcare practices and outcomes for female patients with cardiac rhythm disorders.


Esta revisión explora las disparidades de género en la electrofisiología cardiaca, destacando las diferencias en la actividad eléctrica del corazón entre hombres y mujeres. Se enfatiza la importancia de comprender estas variaciones para un diagnóstico correcto y un tratamiento efectivo de las arritmias cardiacas. Las mujeres muestran características cardiacas distintas influenciadas por las hormonas sexuales, lo que afecta su susceptibilidad a diversas arritmias. La revisión abarca la clasificación, los mecanismos y el manejo de las arritmias en las mujeres, considerando factores como el embarazo y la menopausia. Al abordar estos matices específicos de género, el objetivo es mejorar las prácticas de atención médica y los resultados para las pacientes de sexo femenino con trastornos del ritmo cardiaco.

ABSTRACT

RESUMEN Introducción: El accidente cerebrovascular (ACV) puede generar perturbaciones funcionales y eléctricas del corazón. Las características y mecanismos subyacentes no están completamente elucidados. Objetivo: Evaluar si la isquemia (I) y reperfusión (R) cerebral agudas ocasionan disfunción cardíaca y alteraciones electrocardiográficas en un modelo experimental en ratones. Material y Métodos: Ratones macho sometidos a isquemia y reperfusión cerebral (I/R) fueron evaluados mediante electrocardiografía (ECG) y ecocardiografía. Se analizó la frecuencia cardíaca, el intervalo QT corregido (QTc) y el intervalo entre el pico de la onda T - fin de la onda T (Tp-Te), la fracción de eyección ventricular izquierda (FEVI), la fracción de acortamiento (FA) y el tiempo de relajación isovolumétrica (TRIV). Se cuantificó el tamaño del infarto cerebral (TI), y el déficit neurológico se evaluó con la escala de Longa (EL). Resultados: Encontramos una disminución estadísticamente significativa de la FEVI a las 24 horas de R (I/R: 66,5 ± 1,5% vs. sham: 74,3 ± 0,9%; p=0,002) y la FA (I/R: 42,9 ± 1,7% vs. sham: 52,3 ± 1,7%; p=0,004). Se observó una prolongación del QTc durante la I/R (basal: 125,1 ± 4,3 ms; 60 min I: 143,8 ± 5,2 ms; 24 horas R: 170,3 ± 5,8 ms; p=0,002), sin una prolongación del Tp-Te en la I (basal: 25,9 ± 1,3 ms vs. 60 min I: 23,8 ± 1,4 ms; p=0,999) pero sí en la R (24 horas R: 32,0 ± 2,3 ms; p=0,049. El tamaño del infarto cerebral fue de 34,9 ± 2,5% y la supervivencia del grupo I/R fue del 43,3%. Conclusión: La isquemia cerebral aguda induce una disfunción ventricular izquierda leve y trastornos en la repolarización ventricular que se intensifican en las primeras 24 horas de reperfusión.


ABSTRACT Background: Stroke may produce functional and electrical heart disturbances. The underlying characteristics and mechanisms have not been fully elucidated. Objectives: To evaluate whether acute cerebral ischemia (I) and reperfusion (R) may cause cardiac dysfunction and electrocardiographic alterations in an experimental mice model. Methods: Male mice that underwent cerebral ischemia and reperfusion (I/R) were evaluated by electrocardiography (ECG) and echocardiography. Heart rate, corrected QT (QTc) interval, T-wave peak to T-wave end (Tp-Te) interval, left ventricular ejection fraction (LVEF), shortening fraction (SF) and isovolumetric relaxation time (IVRT) were analyzed. Cerebral infarct size was calculated, and neurological deficit was assessed with the Longa scale. Results: Twenty-four hours after R, a statistically significant decrease in LVEF (I/R: 66.5±1.5% vs. sham: 74.3±0.9%; p=0.002) and in SF (I/R: 42.9±1.7% vs sham: 52.3±1.7%; p=0.004) was observed. QTc interval prolongation was observed during I/R (baseline: 125.1±4.3 ms; 60 min after I: 143.8±5.2 ms; 24 h after R: 170.3±5.8 ms; p=0.002). Tp-Te interval was not prolonged during I (baseline: 25.9±1.3 ms vs. 60 min after I: 23.8±1.4 ms; p=0.999) but it was prolonged during R (24 h after R: 32.0±2.3 ms; p=0.049). Cerebral infarct size was 34.9±2.5% and survival in the I/R group was 43.3%. Conclusion: Acute cerebral ischemia induces mild left ventricular dysfunction and disturbances in ventricular repolarization which intensify within the first 24 hours after reperfusion.

ABSTRACT

Resumo Fundamento: O software ablation index (AI) permitiu melhorar os resultados da ablação de fibrilação atrial (FA), mas as taxas de recorrência permanecem significativas. Biomarcadores séricos específicos têm sido associados a essa recorrência. Objetivos: Avaliar se certos biomarcadores podem ser utilizados (individualmente ou combinados) para predizer a recorrência de FA pós ablação guiada pelo AI. Métodos: Estudo multicêntrico, observacional, prospectivo de pacientes consecutivos, encaminhados para ablação de FA de janeiro de 2018 a março de 2021. Hemoglobina, peptídeo natriurético cerebral (BNP), proteína C reativa, troponina I ultrassensível, clearance de creatinina, Hormônio Tireoestimulante (TSH), e Tiroxina livre (T4) foram avaliados quanto à capacidade de prever a recorrência de arritmias durante o acompanhamento. Valores de p <0,05 foram aceitos como estatisticamente significativos. Resultados: Um total de 593 pacientes foram incluídos - 412 com FA paroxística e 181 com FA persistente. Durante o seguimento médio de 24±6 meses, 76,4% não apresentaram recidiva após ablação. Individualmente, os biomarcadores demonstraram um valor preditivo baixo ou nulo para recorrência. No entanto, TSH >1,8 μUI/mL [HR=1,82 (IC95%, 1,89-2,80), p=0,006] foi um preditor independente de recorrência. Avaliando-se a combinação de TSH, FT4 e BNP, a adição de cada valor "anormal" foi associada a uma menor sobrevida livre de recorrência (87,1% se nenhum vs. 83,5% se um vs. 75,1% se dois vs. 43,3% se três biomarcadores, p<0,001). Doentes com três biomarcadores "anormais" apresentaram três vezes maior probabilidade de recorrência de FA, comparativamente aos que não apresentaram nenhum biomarcador "anormal" (HR=2,88 [IC95%, 1,39-5,17], p=0,003). Conclusões: Quando combinados, valores anormais de TSH, FT4 e BNP podem ser uma ferramenta útil para prever a recorrência de FA pós ablação guiada pelo AI.


Abstract Background: Ablation Index (AI) software has allowed better atrial fibrillation (AF) ablation results, but recurrence rates remain significant. Specific serum biomarkers have been associated with this recurrence. Objectives: To evaluate whether certain biomarkers could be used (either individually or combined) to predict arrhythmia recurrence after AI-guided AF ablation. Methods: Prospective multicenter observational study of consecutive patients referred for AF ablation from January 2018 to March 2021. Hemoglobin, brain natriuretic peptide (BNP), C-reactive protein, high sensitivity cardiac troponin I, creatinine clearance, thyroid-stimulating hormone (TSH) and free thyroxine (FT4) were assessed for their ability to predict arrhythmia recurrence during follow-up. Statistical significance was accepted for p values of<0.05. Results: A total of 593 patients were included - 412 patients with paroxysmal AF and 181 with persistent AF. After a mean follow-up of 24±6 months, overall single-procedure freedom from atrial arrhythmia was 76.4%. Individually, all biomarkers had no or only modest predictive power for recurrence. However, a TSH value >1.8 μUI/mL (HR=1.82 [95% CI, 1.89-2.80], p=0.006) was an independent predictor of arrhythmia recurrence. When assessing TSH, FT4 and BNP values in combination, each additional "abnormal" biomarker value was associated with a lower freedom from arrhythmia recurrence (87.1 % for no biomarker vs. 83.5% for one vs. 75.1% for two vs. 43.3% for three biomarkers, p<0.001). Patients with three "abnormal" biomarkers had a threefold higher risk of AF recurrence compared with no "abnormal" biomarker (HR=2.88 [95% CI, 1.39-5.17], p=0.003). Conclusions: When used in combination, abnormal TSH, FT4 and BNP values can be a useful tool for predicting arrhythmia recurrence after AI-guided AF ablation.

ABSTRACT

Introducción: las bebidas energizantes son preparados estimulantes e hidratos de carbono. Objetivo: determinar la prevalencia, características del consumo y los efectos adversos en estudiantes de un programa de medicina Metodología: estudio observacional, descriptivo, de corte transversal y retrospectivo, que incluyó estudiantes de medicina de una institución de educación superior, excluyendo a aquellos que no cursaban la carga académica completa para su semestre, quienes diligenciaron de manera inadecuada la encuesta o que no aceptaron la participación en el estudio. Resultados y discusión: participaron 241 estudiantes, de los cuales 72,20% eran mujeres. Solo 55 manifestaron trastornos patológicos de tipo insomnio (13,69%) y cefalea o migraña (8,30%) y 49,38% informaron sobre el consumo de bebidas energizantes. Existe la probabilidad de una mezcla con sustancias alcohólicas dada la elevada frecuencia de consumo (51,26%), lo que no ocurrió con el hábito de fumar. Los eventos adversos informados fueron insomnio (21,58%), taquicardia (17,43%), cefalea (14,52%), enrojecimiento facial (13,28%) y en menor medida temblor, ansiedad o trastornos gastrointestinales (17,42%). Conclusiones: el consumo de bebidas energizantes es alta durante la adolescencia y en especial en los universitarios, pero estas sustancias a largo plazo pueden generar efectos adversos cuyas principales complicaciones son cardíacas, por lo que es importante vigilar la comercialización de las mismas.


Introduction: energy drinks (ED) are stimulant and carbohydrate preparations. Objective: to determine the prevalence, characteristics of ED usage and adverse effects among students of a medical program Methodology: an observational, descriptive, cross-sectional, retrospective study, which included medical students of a higher education institution. Those who were not completing the full academic load for their semester, those who responded the survey inadequately or did not agree to participate in the study, were excluded. Results and discussion: 241 students participated, of which 72,20% were females. Only 55 reported symptoms such as insomnia (13.69%) and headache or migraine (8.30%) and 49.38% reported on ED consumption. To combine energy drinks with alcohol is probable, given the high alcohol consumption rate (51.26%), while it was not associated with smoking. Adverse events reported were insomnia (21.58%), tachycardia (17.43%), headache (14.52%), facial flushing (13.28%) and tremor; and to a lesser extent, anxiety, and gastrointestinal disorders (17.42%). Conclusions: energy drinks consumption is high at adolescence, especially among university students. These preparations can produce long-term adverse effects mainly cardiovascular complications. Thus, monitoring ED marketing is important.

ABSTRACT

Resumen Introducida inicialmente en la década de los cincuenta para la evaluación de las presiones de la aurícula izquierda y posteriormente para la realización de valvuloplastia mitral, la punción transeptal es, con frecuencia, la vía de acceso para efectuar procedimientos que involucren las cavidades izquierdas. En la actualidad, se usa comúnmente en los laboratorios de electrofisiología, tanto para la ablación de arritmias en cavidades izquierdas como para los procedimientos de cierre percutáneo de orejuela. No obstante, con la llegada de diversas técnicas para el manejo percutáneo de la válvula mitral, se espera un aumento progresivo de su uso por parte de cardiólogos intervencionistas. En este artículo, se revisa la técnica para hacer una punción transeptal segura y se dan recomendaciones y estrategias para el manejo de la punción transeptal difícil.


Abstract Initially described in 1959 as a technique to measure left atrial pressures, and later used during balloon mitral valvuloplasty, transeptal puncture (TSP) is frequently the access route for procedures involving the left heart chambers. Currently, it is mostly used in electrophysiology laboratories for arrhythmia ablation and during left atrial appendage occlusion procedures. However, with the ongoing development of percutaneous mitral valve interventions, it is expected that a greater number of interventional cardiologists will be using this technique in the near future. In this article, we review the technique to perform TSP safely, and we provide recommendations and different strategies to deal with difficult TSPs.

ABSTRACT

The need to improve access to health services for the transgender community has become evident, especially concerning cardiovascular risk, which is higher compared to the general population. Surgical procedures and hormone therapies are common in this population to affirm gender identity, but they pose challenges as they are associated with disruptions in lipid metabolism, body fat concentration, and insulin resistance. Additionally, there is an increased risk of adverse cardiovascular events such as venous thromboembolism, stroke, and myocardial infarction. The influence of sex hormones on the electrophysiological properties of the heart has been studied, highlighting gender differences that may predispose the transgender population to cardiac arrhythmias. Exogenous hormone therapy, for both transgender women and men, can affect the QT interval and increase the risk of arrhythmias, including atrial fibrillation. Although the incidence of arrhythmias in the transgender population is not entirely clear, evidence suggests the need for careful cardiovascular monitoring and consideration of risk factors before initiating hormone therapies.


La necesidad de mejorar el acceso a servicios de salud para la comunidad transgénero se ha vuelto evidente, especialmente en relación con el riesgo cardiovascular, que es más alto en comparación con la población general. Los procedimientos quirúrgicos y las terapias hormonales son comunes en esta población para reafirmar la identidad de género, pero plantean desafíos, ya que se asocian con alteraciones en el metabolismo de lípidos, la concentración de grasa corporal y la resistencia a la insulina. Además, existe un aumento en el riesgo de eventos cardiovasculares adversos, como tromboembolia venosa, accidente cerebrovascular e infarto de miocardio. La influencia de las hormonas sexuales en las propiedades electrofisiológicas del corazón ha sido estudiada, destacando diferencias entre géneros que pueden predisponer a la población transgénero a arritmias cardiacas. La terapia hormonal exógena, tanto para mujeres como para hombres trans, puede afectar el intervalo QT y aumentar el riesgo de arritmias, incluida la fibrilación auricular. Aunque la incidencia de arritmias en la población transgénero aún no está completamente clara, la evidencia sugiere la necesidad de un monitoreo cardiovascular cuidadoso y la consideración de factores de riesgo antes de iniciar terapias hormonales.

ABSTRACT

Introducción: Las evidencias científicas han demostrado que durante el período pandémico por la COVID-19 ha existido un incremento de la incidencia de muerte súbita cardiovascular, proporcional al incremento de los casos y a la letalidad por la enfermedad. Objetivos: Compilar información sobre los fármacos empleados en el tratamiento de la COVID-19 y sus posibles efectos en la prolongación del intervalo QT y la aparición de muerte súbita. Métodos: Se realizó una búsqueda de información a partir de las bases de datos PubMed, Medline y SciELO, en los idiomas español e inglés en el período de enero de 2020 a enero de 2023. Resultados: Los hallazgos más recientes sugieren que los factores relacionados con el tratamiento médico del paciente para sus enfermedades cardiovasculares previas, el empleo concomitante de drogas para otras comorbilidades, el ensayo de nuevas drogas que se investigan en la actualidad para el tratamiento de la enfermedad y el uso inadecuado de fármacos en complicaciones graves por la COVID-19, pueden ocasionar prolongación del intervalo QT y arritmias ventriculares tipo torsades de pointes, lo que puede conllevar a la aparición de muerte súbita. Conclusiones: Ha sido demostrado el efecto deletéreo de los fármacos en el tratamiento de la COVID-19 y sus posibles asociaciones a la terapéutica del paciente, en la prolongación del tiempo de repolarización ventricular cardíaca, cuya traducción eléctrica es un intervalo QT prolongado y su contribución a la génesis de arritmias malignas potencialmente fatales capaces de desencadenar un paro cardíaco y evolucionar a la muerte súbita(AU)


Scientific evidence has shown an increase in the incidence of sudden cardiovascular death during the COVID-19 pandemic period. This has been proportional to the increase in cases and mortality from the disease. Direct and indirect injury to the myocardium and vascular system allow to partially explain the statistics. Among the factors related to the medical treatment of the patient for previous cardiovascular diseases, it is the concomitant use of drugs for other comorbidities. The trial of new drugs for the treatment of this condition and the inappropriate use of drugs in serious complications from COVID-19 are currently being investigated. These can cause QT prolongation and torsades de pointes ventricular arrhythmias, which can lead to sudden death. Monitoring the QT interval is recommended, before and during treatment, in patients who come to the emergency room with a clinical condition suggestive of COVID-19. Additionally, modifiable factors favoring its prolongation should be evaluated. Decision-making in the application of therapeutic protocols in patients with COVID-19 with prolonged QTc at baseline, or with increased QTc after starting treatment, must go through the analysis of the risk/benefit ratio defined by a multi- and interdisciplinary team(AU)

ABSTRACT

Commotio cordis o conmoción cardíaca es un síndrome arritmogénico mecano-eléctrico raro y mortal. Es la segunda causa de muerte súbita en atletas jóvenes. Se asocia con una lesión que se produce durante la práctica deportiva, en la que un proyectil impacta a alta velocidad en el precordio y provoca una arritmia que conduce a la muerte inmediata del individuo sin una reanimación cardíaca. En las autopsias, los corazones son estructuralmente sanos. Con el conocimiento de este síndrome y las capacitaciones de reanimación cardiorrespiratoria a la comunidad, las tasas de supervivencia han mejorado. El objetivo de este trabajo es describir un paciente que llegó a nuestro hospital con conmotio cordis y su evolución, enfatizando la importancia de medidas de prevención y capacitación de la población en técnicas de reanimación cardiopulmonar y uso del desfibrilador externo automático para la supervivencia de los pacientes que sufren esta entidad.


Commotio cordis or cardiac concussion is a rare and fatal mechano-electric arrhythmogenic syndrome. It is the second most common cause of sudden cardiac death in young athletes. It is most commonly associated with a sports-related injury, wherein, there is a high-velocity impact between a projectile and the precordium, causing arrhythmia that leads to the immediate death of the individual without cardiac resuscitation. On autopsy, the heart is structurally normal. With increasing awareness of this condition and community training in cardiopulmonary resuscitation, survival rates have been improving. The objective of this study is to describe the case of a patient who arrived at our hospital with commotio cordis and his course, emphasizing the importance of prevention and training of the population in cardiopulmonary resuscitation techniques and the use of the automated external defibrillator for the survival of patients suffering from commotio cordis.

ABSTRACT

Las taquicardiomiopatías por su fisiopatología de pérdida del acoplamiento miocárdico, proporcionan el sustrato adecuado para la disfunción ventricular que dan paso a arritmias ventriculares letales. Se reporta el caso de una paciente femenina de 75 años, sin antecedentes personales patológicos conocidos, que acude con historia de disnea de medianos esfuerzos que rápidamente progresa a disnea de pequeños esfuerzos asociado a palpitaciones. Posteriormente desarrolla taquicardia ventricular polimorfa no sostenida durante su estancia hospitalaria por lo que fue necesario realizar en dos ocasiones maniobras de reanimación con cardioversión eléctrica y el restablecimiento del ritmo sinusal con fármacos para mejorar la función del ventrículo izquierdo.

ABSTRACT

Resumo Fundamento A fibrilação atrial (FA) acomete cerca de 2% a 4% da população mundial. Nos pacientes internados em unidades de terapia intensiva, esta incidência pode chegar em até 23% naqueles com choque séptico. O impacto da FA nos pacientes sépticos se reflete em piores desfechos clínicos e o reconhecimento dos fatores desencadeantes pode ser alvo para estratégias de tratamento e prevenção futuras. Objetivos Verificar a relação entre desenvolvimento de FA e mortalidade nos pacientes acima de 80 anos incluídos no protocolo sepse e identificar fatores de risco que contribuam para o desenvolvimento de FA nesta população. Métodos Estudo observacional retrospectivo, com revisão de prontuários eletrônicos e inclusão de 895 pacientes com 80 anos ou mais, incluídos no protocolo sepse de um hospital privado de alta complexidade em São Paulo/SP, no período de janeiro de 2018 a dezembro de 2020. Todos os testes foram realizados com nível de significância de 5%. Resultados A incidência de FA na amostra foi de 13%. Após análise multivariada por regressão logística múltipla, foi possível demonstrar associação de mortalidade na população estudada, com o escore SOFA ( odds ratio [OR] 1,21 [1,09 - 1,35]), valores mais altos de proteína C-reativa (OR 1,04 [1,01 - 1,06]), necessidade de droga vasoativa (OR 2,4 [1,38 - 4,18]), uso de ventilação mecânica (OR 3,49 [1,82 - 6,71]) e principalmente FA (OR 3,7 [2,16 - 6,31). Conclusões No paciente grande idoso (80 anos ou mais) com sepse, o desenvolvimento de FA se mostrou como fator de risco independente para mortalidade intra-hospitalar.


Abstract Background Atrial fibrillation (AF) affects about 2% to 4% of the world population, and in patients hospitalized in intensive care units, this incidence can reach up to 23% in those with septic shock. The impact of AF in patients with sepsis is reflected in worse clinical outcomes, and the identification of the triggering factors can be a target for future prevention and treatment strategies. Objectives To verify the relationship between the development of AF and mortality in patients over 80 years of age included in the sepsis protocol and to identify the risk factors that contribute to the development of AF in this population. Methods Retrospective observational study, with a review of electronic medical records and inclusion of 895 patients aged 80 years or older, included in the sepsis protocol of a high-complexity private hospital in São Paulo, SP, from January 2018 to December 2020. All tests were performed with a significance level of 5%. Results The incidence of AF in the sample was 13%. After multivariate analysis, using multiple logistic regression, it was possible to demonstrate an association of mortality, in the studied population, with the SOFA score (odds ratio [OR] 1.21 [1.09 - 1.35]), higher values of C-reactive protein (OR 1.04 [1.01 - 1.06]), need for vasoactive drugs (OR 2.4 [1.38 - 4.18]), use of mechanical ventilation (OR 3.49 [1.82 - 6.71]), and mainly AF (OR 3.7 [2.16 - 6.31]) Conclusion In very elderly patients (80 years of age and older) with sepsis, the development of AF was shown to be an independent risk factor for in-hospital mortality.
