ABSTRACT

Abstract Background Vitamin K antagonists (VKA) are indicated for the prevention of thromboembolic events and reduction of mortality in patients with atrial fibrillation and patients with valvular prostheses. However, their use is associated with bleeding complications and hospitalizations. Predictors of hospital admission for bleeding in these patients are poorly known. Objectives To define the predictors for hospitalization of VKA users who seek emergency care due to bleeding. Methods Single-center, cross-sectional study, with retrospective analysis of electronic medical records from 03/01/2012 to 02/27/2017. Clinical and laboratory variables were compared between patients who were hospitalized and those who were not. A logistic regression model as used, in which the variables were included using the Backward stepwise method, with a p value of 0.05 as the input criterion, a removal value of 0.20 and a confidence interval of 95%. The p-value was considered statistically significant when <0.05. Results A total of 510 patients with bleeding were included, of whom 158 were hospitalized. Predictors of hospitalization were: INR at supratherapeutic levels (OR 3.45; P <0.01; 95% CI 1.58 - 7.51), gastrointestinal bleeding (OR 2.36; P <0.01; CI 95% 1.24 - 4.50), drop in hemoglobin (OR 6.93; P <0.01; 95% CI 3.67 - 13.07), heart failure (OR 1.96; P 0.01; 95% CI 1.16 - 3.30) and need for blood transfusion (OR 8.03; P <0.01; 95% CI 2.98 - 21.64). Conclusion Drop in hemoglobin, heart failure, INR at supratherapeutic levels, gastrointestinal bleeding and need for blood transfusion were associated with hospitalization. Identification of these factors in the initial evaluation would help to define which patients will demand more intensive care.

ABSTRACT

Abstract Background: The use of Cardiovascular Implantable Electronic Devices (CIED), such as the Implantable Cardioverter Defibrillator (ICD) and Cardiac Resynchronization Therapy (CRT), is increasing. The number of leads may vary according to the device. Lead placement in the left ventricle increases surgical time and may be associated with greater morbidity after hospital discharge, an event that is often confused with the underlying disease severity. Objective: To evaluate the rate of unscheduled emergency hospitalizations and death after implantable device surgery stratified by the type of device. Methods: Prospective cohort study of 199 patients submitted to cardiac device implantation. The groups were stratified according to the type of device: ICD group (n = 124) and CRT group (n = 75). Probability estimates were analyzed by the Kaplan-Meier method according to the outcome. A value of p < 0.05 was considered significant in the statistical analyses. Results: Most of the sample comprised male patients (71.9%), with a mean age of 61.1 ± 14.2. Left ventricular ejection fraction was similar between the groups (CRT 37.4 ± 18.1 vs. ICD 39.1 ± 17.0, p = 0.532). The rate of unscheduled visits to the emergency unit related to the device was 4.8% in the ICD group and 10.6% in the CRT group (p = 0.20). The probability of device-related survival of the variable "death" was different between the groups (p = 0.008). Conclusions: Patients after CRT implantation show a higher probability of mortality after surgery at a follow-up of less than 1 year. The rate of unscheduled hospital visits, related or not to the implant, does not differ between the groups.


Resumo Fundamento: O uso de dispositivos cardíacos eletrônicos implantáveis (DCEI) como o cardiodesfibrilador (CDI) e terapia de ressincronização cardíaca (TRC) - é cada vez maior. O número de eletrodos de estimulação e desfibrilação varia de acordo com o dispositivo. A colocação do eletrodo no ventrículo esquerdo aumenta o tempo cirúrgico podendo associar-se a maior morbidade no acompanhamento após alta hospitalar, evento muitas vezes confundível com a gravidade da patologia base. Objetivo: Avaliar a taxa de internação não programada na emergência e óbito após cirurgia de dispositivos implantáveis estratificados pelo tipo de aparelho. Métodos: Estudo de coorte prospectivo analisando 199 pacientes submetidos à implante de dispositivos cardíacos. Os grupos foram divididos de acordo com o tipo de dispositivo: CDI (n = 124) e TRC (n = 75). Estimativas de probabilidades foram analisadas pelo método de Kaplan-Meier de acordo com o desfecho. Valor de p < 0,05 foi considerado significativo nas análises estatísticas. Resultados: A maioria da amostra era do sexo masculino (71,9%) - idade média de 61,1 ± 14,2. A fração de ejeção do ventrículo esquerdo foi similar entre os grupos (TRC 37,4 ± 18,1 vs. CDI 39,1 ± 17,0; p = 0,532). A taxa de visita não programada na emergência relacionada ao dispositivo foi de 4,8% no grupo CDI e de 10,6% no grupo TRC (p = 0,20). A probabilidade de sobrevida relacionada ao dispositivo da variável "óbito" mostrou-se diferente entre os grupos (p = 0,008). Conclusões: Paciente após o implante de TRC apresenta maior probabilidade de mortalidade após o procedimento cirúrgico no seguimento menor que 1 ano. A taxa de visita hospitalar não programada, relacionadas ou não ao implante, não difere entre os grupos.

ABSTRACT

Abstract Severe carotid atherosclerotic disease is responsible for 14% of all strokes, which result in a high rate of morbidity and mortality. In recent years, advances in clinical treatment of cardiovascular diseases have resulted in a significant decrease in mortality due to these causes. To review the main studies on carotid revascularization, evaluating the relationship between risks and benefits of this procedure. The data reviewed show that, for a net benefit, carotid intervention should only be performed in cases of a periprocedural risk of less than 6% in symptomatic patients. The medical therapy significantly reduced the revascularization net benefit ratio for stroke prevention in asymptomatic patients. Real life registries indicate that carotid stenting is associated with a greater periprocedural risk. The operator annual procedure volume and patient age has an important influence in the rate of stroke and death after carotid stenting. Symptomatic patients have a higher incidence of death and stroke after the procedure. Revascularization has the greatest benefit in the first weeks of the event. There is a discrepancy in the scientific literature about carotid revascularization and/or clinical treatment, both in primary and secondary prevention of patients with carotid artery injury. The identification of patients who will really benefit is a dynamic process subject to constant review.


Resumo A doença aterosclerótica carotídea grave é responsável por 14% de todos os acidentes vasculares cerebrais (AVC), que refletem em uma alta taxa de morbimortalidade. Nos últimos anos, os avanços no tratamento clínico das doenças cardiovasculares geraram um decréscimo importante na mortalidade por estas causas. Revisar principais estudos que dizem respeito à revascularização carotídea avaliando a relação entre risco e beneficio deste procedimento. Os dados encontrados indicam que o procedimento só deve ser realizado se houver um risco periprocedimento menor que 6% em pacientes sintomáticos para que haja beneficio líquido na intervenção carotídea. O tratamento clínico reduziu significativamente o benefício líquido da revascularização na prevenção de AVC em pacientes assintomáticos. Registros que refletem a prática diária demonstram que a angioplastia carotídea esta associada a um risco periprocedimento mais elevado. O volume anual de procedimentos por operador e a idade dos pacientes têm uma importante influência nas taxas de AVC e morte pós angioplastia. Pacientes sintomáticos têm uma maior incidência de AVC e morte após procedimento. A revascularização tem o maior benefício nas primeiras semanas do evento. Existem discrepâncias na literatura científica com relação à revascularização carotídea e/ou tratamento clínico, tanto na prevenção primária quanto secundária de pacientes com lesão carotídea. A identificação do paciente que realmente será beneficiado é um processo dinâmico sujeito a constante revisão.

ABSTRACT

Abstract Background: The uninterrupted use of oral anticoagulation (OAC) with vitamin K antagonists (VKAs) for electrophysiology procedures has been more and more recommended. The clinical practice in our service recommends the continuous use of these drugs for atrial flutter ablation. There is little evidence as to the uninterrupted use of non-vitamin K antagonist oral anticoagulants (NOACs) in this scenario. Objective: To compare the rates of complications related with the uninterrupted use of different types of oral anticoagulants in patients referred to atrial flutter (AFL) ablation. Methods: Historical, single-center cohort of ablation procedures by AFL conducted from November 2012 to April 2016. The primary outcome was the occurrence of hemorrhagic or embolic complication during the procedure. The secondary outcome was the occurrence of stroke or transient ischemic attack (TIA) in follow-up. The statistical significance level was 5%. Results: There were 288 ablations per AFL; 154 were carried out with the uninterrupted use of OAC (57.8% with VKA and 42.2% with NOAC). Mean age was 57 ± 13 years. The rate of hemorrhagic complication during the procedure was 3% in each group (p = NS). The rate of stroke/TIA was, respectively, of 56/1,000 people-year in the VKA group against zero/1,000 people-year in the NOAC group (p = 0.02). Conclusion: In our population there were no hemorrhagic complications regarding the procedure of OAC use uninterruptedly, including NOACs. There was higher occurrence of stroke/TIA in the follow-up of the group of patients undergoing VKAs; however, this difference may not only be a result of the type of OAC used.


Resumo Fundamento: O uso ininterrupto de anticoagulação oral (ACO) com antagonistas da vitamina K (AVKs) para procedimentos de eletrofisiologia está sendo cada vez mais recomendado. A prática clínica em nosso serviço é de uso continuado dessas drogas para ablação de flutter atrial. Existem poucas evidências quanto ao uso ininterrupto dos anticoagulantes orais não antagonistas da vitamina K (NOACs) nesse cenário. Objetivos: Comparar as taxas de complicações relacionadas ao uso ininterrupto de diferentes tipos de anticoagulantes orais em pacientes referidos para ablação por flutter atrial (FLA). Métodos: Coorte histórica e unicêntrica dos procedimentos de ablação por FLA realizados no período de novembro de 2012 a abril de 2016. O desfecho primário foi o de ocorrência de complicação hemorrágica ou embólica durante o procedimento. O desfecho secundário foi o de ocorrência de acidente vascular cerebral (AVC) ou acidente isquêmico transitório (AIT) no acompanhamento. O nível de significância estatística adotado foi de 5%. Resultados: Foram incluídas 288 ablações por FLA; 154 foram feitas com uso ininterrupto de ACO (57,8% com AVK e 42,2% com NOAC). A idade média foi de 57 ± 13 anos. A taxa de complicação hemorrágica durante o procedimento foi de 3% em cada grupo (p = NS). A taxa de AVC/AIT foi, respectivamente, de 56/1.000-pessoas-ano no grupo AVK contra zero/1.000-pessoas-ano no grupo NOAC (p = 0,02). Conclusão: Em nossa população não ocorreram complicações hemorrágicas relacionadas ao procedimento com uso de ACO de forma ininterrupta, incluindo NOACs. Houve maior ocorrência de AVC/AIT no seguimento no grupo de pacientes em uso de AVK, contudo essa diferença pode não ser decorrente apenas do tipo de ACO em uso.

ABSTRACT

Abstract Background: Atrial fibrillation is responsible for one in four strokes, which may be prevented by oral anticoagulation, an underused therapy around the world. Considering the challenges imposed by this sort of treatment, mobile health support for shared decision-making may improve patients' knowledge and optimize the decisional process. Objective: To develop and evaluate a mobile application to support shared decision about thromboembolic prophylaxis in atrial fibrillation. Methods: We developed an application to be used during the clinical visit, including a video about atrial fibrillation, risk calculators, explanatory graphics and information on the drugs available for treatment. In the pilot phase, 30 patients interacted with the application, which was evaluated qualitatively and by a disease knowledge questionnaire and a decisional conflict scale. Results: The number of correct answers in the questionnaire about the disease was significantly higher after the interaction with the application (from 4.7 ± 1.8 to 7.2 ± 1.0, p < 0.001). The decisional conflict scale, administered after selecting the therapy with the app support, resulted in an average of 11 ± 16/100 points, indicating a low decisional conflict. Conclusions: The use of a mobile application during medical visits on anticoagulation in atrial fibrillation improves disease knowledge, enabling a shared decision with low decisional conflict. Further studies are needed to confirm if this finding can be translated into clinical benefit.


Resumo Fundamento: A fibrilação atrial é causa de um em cada quatro acidentes vasculares cerebrais, que podem ser prevenidos com anticoagulação oral, uma terapia subutilizada globalmente. Considerando os desafios desse tratamento, instrumentos de saúde móvel para suporte à decisão compartilhada podem melhorar o conhecimento do paciente e otimizar o processo decisório. Objetivo: Desenvolver e avaliar um aplicativo móvel para suporte à decisão compartilhada na profilaxia tromboembólica em fibrilação atrial. Métodos: Foi desenvolvido um aplicativo para ser usado durante a consulta médica, contendo um vídeo sobre fibrilação atrial, calculadoras de escores de risco, gráficos explicativos e orientações sobre os fármacos disponíveis para o tratamento. Durante o desenvolvimento, 30 pacientes interagiram com o aplicativo, que foi avaliado qualitativamente e pela aplicação de um questionário de conhecimento sobre a doença e de uma escala de conflito em tomadas de decisão. Resultados: O número de acertos no questionário de conhecimento sobre a doença teve um aumento significativo após a interação com o aplicativo (de 4,7 ± 1,8 para 7,2 ± 1,0, p < 0,001). A escala de conflito em tomadas de decisão, aplicada após a escolha da terapia com o suporte do aplicativo, resultou em uma média de 11 ± 16/100 pontos, indicando baixo conflito decisório. Conclusões: O uso de um aplicativo móvel durante a consulta sobre anticoagulação em fibrilação atrial melhora o conhecimento sobre a doença, permitindo uma escolha compartilhada com baixo conflito decisório. Mais estudos são necessários para verificar se isso se traduz em benefício clínico.

ABSTRACT

Abstract Introduction: Chronic stimulation of the right ventricle with pacemaker is associated with ventricular dyssynchrony and loss of contractility, even in subjects without previous dysfunction. In these patients, there is a debate of which pacing site is less associated with loss of ventricular function. Objective: To compare pacemaker-induced dyssynchrony among different pacing sites in right ventricular stimulation. Methods: Cross-sectional study of outpatients with right ventricle stimulation higher than 80% and preserved left ventricular ejection fraction. Pacing lead position (apical, medial septum or free wall) was assessed through chest X-rays. Every patient underwent echocardiogram to evaluate for dyssynchrony according to CARE-HF criteria: aortic pre-ejection time, interventricular delay and septum/posterior wall delay on M mode. Results: Forty patients were included. Fifty-two percent had apical electrode position, 42% mid septum and 6% free wall. Mean QRS time 148.97±15.52 milliseconds. A weak correlation between the mean QRS width and pre-aortic ejection time (r=0.32; P=0.04) was found. No difference in QRS width among the positions could be noted. Intraventricular delay was lower in apical patients against mid septal (34.4±17.2 vs. 54.3±19.1 P<0.05) - no difference with those electrode on the free wall. No difference was noted in the pre-aortic ejection time (P=0.9). Conclusion: Apical pacing showed a lower interventricular conduction delay when compared to medial septum site. Our findings suggest that apical pacing dyssynchrony is not ubiquitous, as previously thought, and that it should remain an option for lead placement.

ABSTRACT

Introduction:

Atrial fibrillation and atrial flutter account for one third of hospitalizations due to arrhythmias, determining great social and economic impacts. In Brazil, data on hospital care of these patients is scarce.

Objective:

To investigate the arrhythmia subtype of atrial fibrillation and flutter patients in the emergency setting and compare the clinical profile, thromboembolic risk and anticoagulants use.

Methods:

Cross-sectional retrospective study, with data collection from medical records of every patient treated for atrial fibrillation and flutter in the emergency department of Instituto de Cardiologia do Rio Grande do Sul during the first trimester of 2012.

Results:

We included 407 patients (356 had atrial fibrillation and 51 had flutter). Patients with paroxysmal atrial fibrillation were in average 5 years younger than those with persistent atrial fibrillation. Compared to paroxysmal atrial fibrillation patients, those with persistent atrial fibrillation and flutter had larger atrial diameter (48.6 ± 7.2 vs. 47.2 ± 6.2 vs. 42.3 ± 6.4; p < 0.01) and lower left ventricular ejection fraction (66.8 ± 11 vs. 53.9 ± 17 vs. 57.4 ± 16; p < 0.01). The prevalence of stroke and heart failure was higher in persistent atrial fibrillation and flutter patients. Those with paroxysmal atrial fibrillation and flutter had higher prevalence of CHADS2 score of zero when compared to those with persistent atrial fibrillation (27.8% vs. 18% vs. 4.9%; p < 0.01). The prevalence of anticoagulation in patients with CHA2DS2-Vasc ≤ 2 was 40%.

Conclusions:

The population in our registry was similar in its comorbidities and demographic profile to those of North American and European registries. Despite the high thromboembolic risk, the use of anticoagulants was low, revealing difficulties for ...


Fundamento:

A fibrilação atrial e o flutter atrial são responsáveis por um terço das hospitalizações por arritmias, com impacto socioeconômico significativo. Os dados brasileiros a respeito desses atendimentos são escassos.

Objetivo:

Investigar o subtipo fibrilação atrial ou flutter em pacientes atendidos em emergência em virtude dessas arritmias e comparar os perfis de comorbidades, risco de eventos tromboembólicos e uso de anticoagulantes.

Métodos:

Estudo transversal retrospectivo, com coleta de dados de prontuário de todos os pacientes atendidos por flutter e fibrilação atrial na emergência do Instituto de Cardiologia do Rio Grande do Sul no primeiro trimestre de 2012.

Resultados:

Foram incluídos 407 pacientes (356 com fibrilação atrial e 51 com flutter). Os pacientes com fibrilação atrial paroxística eram, em média, 5 anos mais jovens do que aqueles com fibrilação atrial persistente. Comparados àqueles com fibrilação atrial paroxística, os pacientes com fibrilação atrial persistente e flutter tinham maior diâmetro atrial (48,6 ± 7,2 vs. 47,2 ± 6,2 vs. 42,3 ± 6,4; p < 0,01) e menor fração de ejeção (66,8 ± 11 vs. 53,9 ± 17 vs. 57,4 ± 16; p < 0,01). A prevalência de acidente vascular cerebral e insuficiência cardíaca foi maior naqueles com fibrilação atrial persistente e flutter. Os pacientes com fibrilação atrial paroxística e flutter apresentavam mais frequentemente escore CHADS2 de zero em relação àqueles com fibrilação atrial persistente (27,8% vs. 18% vs. 4,9%; p < 0,01). A prevalência de anticoagulação nos pacientes com escore CHA2DS2-Vasc ≥ 2 foi de 40%.

Conclusão:

A população de nossa amostra teve características demográficas e perfil de comorbidades ...

ABSTRACT

Background: Diabetes mellitus and admission blood glucose are important risk factors for mortality in ST segment elevation myocardial infarction patients, but their relative and individual role remains on debate. Objective: To analyze the influence of diabetes mellitus and admission blood glucose on the mortality of ST segment elevation myocardial infarction patients submitted to primary coronary percutaneous intervention. Methods: Prospective cohort study including every ST segment elevation myocardial infarction patient submitted to primary coronary percutaneous intervention in a tertiary cardiology center from December 2010 to May 2012. We collected clinical, angiographic and laboratory data during hospital stay, and performed a clinical follow-up 30 days after the ST segment elevation myocardial infarction. We adjusted the multivariate analysis of the studied risk factors using the variables from the GRACE score. Results: Among the 740 patients included, reported diabetes mellitus prevalence was 18%. On the univariate analysis, both diabetes mellitus and admission blood glucose were predictors of death in 30 days. However, after adjusting for potential confounders in the multivariate analysis, the diabetes mellitus relative risk was no longer significant (relative risk: 2.41, 95% confidence interval: 0.76 - 7.59; p-value: 0.13), whereas admission blood glucose remained and independent predictor of death in 30 days (relative risk: 1.05, 95% confidence interval: 1.02 - 1.09; p-value ≤ 0.01). Conclusion: In ST segment elevation myocardial infarction patients submitted to primary coronary percutaneous intervention, the admission blood glucose was a more accurate and robust independent predictor of death than the previous diagnosis of diabetes. This reinforces the important role of inflammation on the outcomes of this group of patients. .


Fundamento: Diabetes Mellitus e glicemia de admissão são importantes fatores de risco para mortalidade em pacientes com infarto agudo do miocárdio com elevação do segmento ST, mas a contribuição relativa e independente de cada um deles permanece em debate na literatura. Objetivo: Analisar a influência de diabetes mellitus e da glicemia de admissão na mortalidade de pacientes com infarto agudo do miocárdio com elevação do segmento ST submetidos à intervenção coronariana percutânea primária. Métodos: Estudo de coorte prospectivo incluindo todos os pacientes com infarto agudo do miocárdio com elevação do segmento ST submetidos à intervenção coronariana percutânea primária em um centro terciário de cardiologia no período de dezembro de 2010 a maio de 2012. Foram coletados dados clínicos, laboratoriais e angiográficos, com seguimento clínico de 30 dias após o evento. A análise multivariada dos fatores de risco estudados foi ajustada para as variáveis do escore GRACE. Resultados: Dentre os 740 pacientes incluídos, a prevalência de diabetes mellitus relatada foi de 18%. Na análise simples, tanto diabetes mellitus quanto glicemia de admissão foram preditores de mortalidade em 30 dias. Entretanto, após ajuste de potenciais confundidores na análise multivariada, o risco proporcionado pelo diabetes mellitus deixou de ser significativo (risco relativo: 2,41, intervalo de confiança de 95%: 0,76 - 7,59; p = 0,13) enquanto a glicemia de admissão permaneceu como preditor independente de mortalidade em 30 dias (risco relativo: 1,05, intervalo de confiança de 95%: 1,02 - 1,09; p ≤ 0,01) Conclusão: Em pacientes com infarto agudo do miocárdio com elevação do segmento ST submetidos à intervenção ...
