ABSTRACT

BACKGROUND: It is estimated that atrial fibrillation (AF) affects approximately 1.5 million people in Brazil; however, epidemiological data are limited. We sought to evaluate the characteristics, treatment patterns, and clinical outcomes in patients with AF in Brazil by creating the first nationwide prospective registry. METHODS: RECALL was a multicenter, prospective registry that included and followed for 1 year 4,585 patients with AF at 89 sites across Brazil from April 2012 to August 2019. Patient characteristics, concomitant medication use, and clinical outcomes were analyzed using descriptive statistics and multivariable models. RESULTS: Of 4,585 patients enrolled, the median age was 70 (61, 78) years, 46% were women, and 53.8% had permanent AF. Only 4.4% of patients had a history of previous AF ablation and 25.2% had a previous cardioversion. The mean (SD) CHA2DS2-VASc score was 3.2 (1.6); median HAS-BLED score was 2 (2, 3). At baseline, 22% were not on anticoagulants. Of those taking anticoagulants, 62.6% were taking vitamin K antagonists and 37.4% were taking direct oral anticoagulants. The primary reasons for not using an oral anticoagulant were physician judgment (24.6%) and difficulty in controlling (14.7%) or performing (9.9%) INR. Mean (SD) TTR for the study period was 49.5% (27.5). During follow-up, the use of anticoagulants and INR in the therapeutic range increased to 87.1% and 59.1%, respectively. The rates/100 patient-years of death, hospitalization due to AF, AF ablation, cardioversion, stroke, systemic embolism, and major bleeding were 5.76 (5.12-6.47), 15.8 (14.6-17.0), 5.0 (4.4-5.7), 1.8 (1.4-2.2), 2.77 (2.32-3.32), 1.01 (0.75-1.36), and 2.21 (1.81-2.70). Older age, permanent AF, New York Heart Association class III/IV, chronic kidney disease, peripheral arterial disease, stroke, chronic obstructive pulmonary disease, and dementia were independently associated with increased mortality while the use of anticoagulant was associated with lower risk of death. CONCLUSIONS: RECALL represents the largest prospective registry of patients with AF in Latin America. Our findings highlight important gaps in treatment, which can inform clinical practice and guide future interventions to improve the care of these patients.

ABSTRACT

A fibrilação atrial (FA) é a arritmia cardíaca sustentada mais comum na prática clínica. Estima se que 1 a 2% da população mundial seja acometida dessa arritmia e ainda se reconhece que este número está subestimado, dado que até um terço dos pacientes com FA são assintomáticos. Além dos fatores de risco clássicos como diabetes, doença valvar, infarto do miocárdio e insuficiência cardíaca, insuficiência renal crônica, obesidade e apneia obstrutiva do sono, a hipertensão tem um papel muito impactante no surgimento da FA pela sua alta prevalência, com isso sendo o fator de risco mais comum para o desenvolvimento de FA. O manejo adequado da HA é importante para prevenção da FA, controle do ritmo, insuficiência cardíaca e prevenção do acidente vascular cerebral (AVC). O tratamento deve ser integrado por equipe multidisciplinar, individualizando caso a caso, estando sujeito a mudanças ao longo do tempo, com o desenvolvimento de novos fatores de risco, sintomas, progressão da doença e com advento de novos tratamentos. Algumas drogas, tais como os BRAs e iECA parecem apresentar mecanismos específicos de atuação na redução do risco de arritmias. A ablação por cateter pode ser a estratégia mais eficaz para manutenção do ritmo sinusal, em paciente sintomáticos. O objetivo dessa revisão é resumir os dados atuais referente ao manejo do paciente hipertenso com fibrilação atrial.


Worldwide, AF is the most common sustained cardiac arrhythmia in adults. The currently estimated prevalence and incidence in the world are rising, owing to extended longevity and increased survival with chronic diseases. This multifactorial arrhythmia is intertwined with common concomitant cardiovascular diseases, which share classical cardiovascular risk factors, including hypertension, diabetes mellitus, heart failure (HF), coronary artery disease (CAD), chronic kidney disease (CKD), obesity, and obstructive sleep apnoea (OSA). The most common risk factor for AF in the general population is hypertension, and in these patients, left ventricular hypertrophy followed by left atrial enlargement creates the anatomical substrate for AF. Adequate management of hypertension is important for AF prevention, rhythm control, heart failure, and stroke prevention. Integrated management of AF patients requires a coordinated and agreed patient-individualized care pathway to deliver optimized treatment by an interdisciplinary team. The effect of some anti hypertensives, such as RAAS Inhibitors seems to be superior to other antihypertensive treatment to prevent AF recurrences in hypertensive patients with paroxysmal AF beyond the BP reduction. Guidelines suggest a more prominent role for radiofrequency ablation in the treatment of atrial fibrillation (AF), including its use as first-line therapy in recurrent symptomatic paroxysmal or persistent AF in whom a rhythm control strategy is chosen. The objective of this review is to summarize current data on the hypertension in relation to AF, their management, and ongoing research in the field.

ABSTRACT

Resumo Fundamento Episódios de alta frequência atrial (EAFAs) estão associados a um risco elevado de eventos isquêmicos cerebrais, porém não existem estudos relacionados com a presença de EAFAs e eventos isquêmicos cerebrais em pacientes chagásicos. Objetivo Investigar a associação entre a presença de EAFAs ≥ 6 minutos e eventos isquêmicos cerebrais em pacientes chagásicos. Métodos Estudo de coorte com pacientes chagásicos, portadores de dispositivos cardíacos eletrônicos implantáveis (DCEIs), acompanhados no ambulatório de arritmias de um hospital universitário, na cidade de Salvador/BA, entre maio de 2016 e junho de 2017. Pacientes com diagnóstico de flutter atrial/fibrilação atrial, com DCEI unicameral e em uso de anticoagulação oral foram excluídos. Foram considerados EAFAs com frequência atrial ≥ 190 batimentos por minuto e duração ≥ 6 minutos (min), e os eventos isquêmicos cerebrais foram identificados por meio de tomografia computadorizada (TC) de crânio. Resultados Os 67 participantes da pesquisa (67,2% do sexo feminino, com idade média de 63,6 ± 9,2 anos) foram acompanhados por 98 ± 28,8 dias e 11,9% dos pacientes apresentaram EAFAs ≥ 6 minutos. A TC de crânio evidenciou eventos isquêmicos cerebrais silenciosos em 16,4% dos pacientes, sendo que, destes, 63,6% haviam apresentado os EAFAs ≥ 6 minutos na análise dos DCEIs. A idade avançada (OR 1,12 [IC 95% 1,03-1,21; p=0,009) e a presença de EAFAs ≥ 6 minutos (OR 96,2 [IC 95% 9,4-987,4; p<0,001]) foram preditores independentes para eventos isquêmicos. Conclusão EAFAs detectados por DCEIs estavam associados à presença de eventos isquêmicos cerebrais silenciosos em pacientes chagásicos. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)


Abstract Background Atrial high-rate episodes (AHREs) are associated with an increased risk of cerebral ischemic events; however, there are no studies related to the presence of AHREs and cerebral ischemic events in Chagasic patients. Objective To investigate the association between the presence of AHREs ≥ 6 minutes and cerebral ischemic events in Chagasic patients. Methods Cohort study with Chagasic patients with implantable electronic cardiac devices (IECDs), followed at the Arrhythmia Outpatient Clinic of a University Hospital, in the city of Salvador, state of Bahia, Brazil, between May 2016 and June 2017.. Patients diagnosed with atrial flutter / atrial fibrillation, with unicameral IECD and using oral anticoagulation were excluded. AHREs with atrial frequency ≥ 190 beats per minute and duration ≥ 6 minutes (min) were considered, and cerebral ischemic events were identified by computed tomography (CT) of the skull. Results The 67 research participants (67.2% females, mean age 63.6 ± 9.2 years) were followed for 98 ± 28.8 days and 11.9% of the patients had AHREs ≥ 6 min. Skull CT showed silent cerebral ischemic events in 16.4% of the patients, 63.6% of whom had AHREs ≥ 6 min in the analysis of IECDs. Advanced age [OR 1.12 (95% CI 1.03-1.21; p=0.009] and the presence of AHREs ≥ 6 minutes [OR 96.2 (95% CI 9.4-987.4; p <0.001)] were independent predictors for ischemic events. Conclusion AHREs detected by IECDs were associated with the presence of silent cerebral ischemic events in Chagasic patients. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

ABSTRACT

To discuss and share knowledge about advances in the care of patients with thrombotic disorders, the Ninth International Symposium of Thrombosis and Anticoagulation was held in Salvador, Bahia, Brazil, on October 15, 2016. This scientific program was developed by clinicians for clinicians and was promoted by two major clinical research institutes-the Brazilian Clinical Research Institute and the Duke Clinical Research Institute of the Duke University School of Medicine. Comprising academic presentations and open discussion, the symposium had as its primary goal to educate, motivate, and inspire internists, cardiologists, hematologists, and other physicians by convening national and international visionaries, thought-leaders, and dedicated clinician-scientists. This paper summarizes the symposium proceedings.

ABSTRACT

O manuseio do portador de dispositivos cardíacos implantáveis com arritmias atriais envolve profilaxia de eventos tromboembólicos, controle do ritmo ou da frequência cardíaca, cuidados com a anticoagulação e programação adequada. Esta revisão tem como objetivo avaliar o uso desses dispositivos na detecção de arritmias atriais, bem como a anticoagulação oral em seus portadores e o manuseio perioperatório de tais fármacos em implantes, revisões ou trocas de geradores de pulsos. Cuidados com a programação dos dispositivos, bem como a utilidade dos algoritmos de estimulação atrial rápida na interrupção de arritmias atriais também são destacados.


The management of patients with implantable cardiac devices and atrial arrhythmias involves the prophylaxis of thromboembolic events, heart rate or rhythm control, anticoagulation care and appropriate programming. This review aims to evaluate the use of these devices to detect atrial arrhythmias as well as oral anticoagulation in the patients and the peri-operative management of these drugs in the implants, reviews or exchange of pulse generators. Appropriate programming of the devices and the use of atrial overdrive pacing to prevent atrial tachycardia are also highlighted.

ABSTRACT

As taquicardias supraventriculares são comuns na prática clínica e, apesar de raramente levarem a morte, são motivos de visitas frequentes a pronto-socorros, piora da qualidade de vida e elevados custos ao sistema de saúde. O tratamento medicamentoso, apesar de amplamente empregado, tem demonstrado eficácia limitada e seu uso a longo prazo encontra-se associado ao desenvolvimento de efeitos colaterais. O conhecimento dos mecanismos destas arritmias favoreceram o desenvolvimento de técnicas e tecnologias intervencionistas seguras e altamente eficazes no controle e na cura destas doenças. Vários estudos têm demonstrado o custo-efetividade, bem como a superior eficácia da ablação nas taquicardias paroxísticas supraventriculares e no flutter atrial quando comparada ao tratamento medicamentoso. Apesar de ainda não ser possível a cura da fibrilação atrial por meio da ablação, esta ferramenta tem se mostrado superior ao tratamento farmacológico no controle dos sintomas e nos casos paroxísticos, evidências apontam que a ablação é capaz de retardas a progressão da doença. A despeito deste conhecimento, algumas evidências apontam que, no Brasil, este recurso vem sendo subaproveitado. Este trabalho tem como objetivo revisar as indicações de ablação das arritmias supraventriculares, bem como fornecer noções técnicas destas ferramentas terapêuticas.


Supraventricular tachycardias are common in clinical practice and rarely lead to sudden death but are a frequent reason for visits to emergency rooms, poor quality of life and high costs to the health system. Drug treatment shown limited efficacy and its long-term use is associated with side effects. Knowledge of the mechanisms related to these arrhythmias favored the development of safe and highly effective interventional technologies in the control and cure of these diseases. Several studies have demosntrated the cost-effectiveness as well as the superior efficacy of catheter ablation in the treatment of paroxysmal supraventricular tachycardia and trial flutter when compared to medical therapy. Although results of catheter ablation of atrial fibrilation are modest, they are modest, they are superior to pharmalogical for symptoms control. This paper reviews the indications for ablation of supraventricular arrhythmias as well as provides technical notions regarding these therapeutic tools still under utilized in Brazil.

ABSTRACT

FUNDAMENTO: A despeito de elevada prevalência e importância clínica da Fibrilação Atrial (FA), não existem até o momento publicações brasileiras informando o perfil clínico e a estratégia de tratamento (controle de ritmo vs. controle de frequência cardíaca) mais utilizada nesse universo de pacientes. OBJETIVO: Avaliar a estratégia de tratamento mais empregada na FA em ambulatório especializado no manejo dessa doença. Secundariamente, procurou-se descrever o perfil clínico dessa população. MÉTODOS: Estudo transversal que avaliou sequencialmente, em 167 portadores de FA, a estratégia de tratamento mais empregada, bem como o perfil clínico desses pacientes. Utilizou-se questionário padronizado para coleta de dados. A análise estatística foi realizada por meio do software SPSS® versão 13.0. RESULTADOS: Nessa população de alto risco para eventos tromboembólicos (61% com score CHADS2 > 2), em que 54% dos indivíduos apresentavam fibrilação atrial paroxística ou persistente, 96,6% utilizavam antagonistas da vitamina K ou AAS, e 76,6% faziam uso de betabloqueador (81,2% frequência x 58,8% ritmo, p < 0,05); a estratégia de controle de frequência foi a mais empregada (79,5% x 20,5%, p < 0,001). Houve uma tendência estatística a maior agrupamento de pacientes com disfunção ventricular (15,2% x 2,9%; p = 0,06), CHADS2 > 2 (60,5% x 39,5%; p = 0,07) e valvopatias (25,8% x 11,8%; p = 0,08) no segmento de controle da frequência. CONCLUSÃO: Nessa população de alto risco para eventos tromboembólicos, a estratégia de controle de frequência cardíaca foi a mais empregada.


BACKGROUND: Despite the high prevalence and clinical importance of atrial fibrillation (AF), there is no Brazilian study about the clinical profile of patients with AF and the most used treatment strategy (heart rhythm control vs. heart rate control) for them. OBJECTIVE: To assess the most used treatment strategy for AF in an outpatient clinic specialized in the management of that disease. In addition, the clinical profile of the population studied was provided. METHODS: Cross-sectional study assessing sequentially, in 167 patients with AF, the most used treatment strategy, as well as their clinical profile. A standardized form was used for data collection. The statistical analysis was performed by using the SPSS® software, version 13.0. RESULTS: In that population at high risk for thromboembolic events (61% had CHADS2 > 2), 54% of the patients had paroxysmal or persistent AF, 96.6% used vitamin K antagonists or acetylsalicylic acid, and 76.6% used beta-blocker (heart rate, 81.2% x heart rhythm, 58.8%; p < 0.05). Heart rate control was the most used treatment strategy (79.5% x 20.5%; p < 0.001). A statistical tendency towards more patients with ventricular dysfunction (15.2% x 2.9%; p = 0.06), CHADS2 > 2 (60.5% x 39.5%; p = 0.07) and heart valve diseases (25.8% x 11.8%; p = 0.08) was observed in the heart rate control group. CONCLUSION: In that population at high risk for thromboembolic events, the heart rate control strategy was the most used.

ABSTRACT

BACKGROUND: Despite the high prevalence and clinical importance of atrial fibrillation (AF), there is no Brazilian study describing the clinical profile of patients with AF and the most used treatment strategy (rhythm control vs. rate control). OBJECTIVE: Assess the most common treatment on AF in an outpatient specialized clinic for management of AF. In addition, the clinical profile of the population studied was provided. METHODS: Cross-sectional study assessing the most used strategy for atrial fibrillation control in 167 patients. The clinical profile was also described. A standardized form was used for data collection and statistical analysis was performed by SPSS 13.0 software. RESULTS: In This high risk population for thromboembolic events (61% had CHADS(2) ≥ 2), 54% of patients had paroxysmal or persistent AF, 96.6% were on vitamin K antagonists or acetylsalicylic acid, and 76.6% on beta-blocker (rate control 81,2% x rhythm control 58,8%; p < 0.05). Heart rate control was the most used strategy (79.5% x 20.5%; p < 0.001). A statistical tendency towards more patients with ventricular dysfunction (15.2% x 2.9%; p = 0.06), CHADS(2) ≥ 2 (60.5% x 39.5%; p = 0.07) and heart valve diseases (25.8% x 11.8%; p = 0.08) was observed in the heart rate control group. CONCLUSION: In this high risk population for thromboembolic events, the rate control strategy was the most used.

ABSTRACT

A síndrome metabólica é um transtorno clínico complexo, representado por um conjunto de fatores de risco responsável pelo significativo aumento da mortalidade tanto geral como cardiovascular. Sua etiopatogenia é multifatorial , tendo-se atribuído grande peso à resistência insulínica, decorrente do acúmulo de gordura visceral. A hiperglicemia sustentada é responsável pela modificação estrutural de proteínas e de outras moléculas do organismo, as quais se tornam mais propensas a modificações oxidativas. O estresse oxidativo tem sido implicado em todos os estágios da aterogênese, promovendo estágio inflamatório e dedisfunção endotelial.A fibrilação atrialé a taquiarritmia sustentada mais frequente na prática clínica. Sua prevalência aumenta com vançar da idade e está associada a custo elevado para os sistemas de saúde, como também a elevada taxa de morbidade secundária a complicações como acidente vascular cerebral e insuficiência cardíaca...
