ABSTRACT

Resumo Fundamento O desequilíbrio do sistema nervoso autônomo (SNA) na insuficiência cardíaca (IC) cria um ciclo vicioso, o excesso de atividade simpática e a diminuição da atividade vagal contribuindo para a piora da IC. A estimulação elétrica transcutânea de baixa intensidade do ramo auricular do nervo vago (taVNS) é bem tolerada e abre novas possibilidades terapêuticas. Objetivos Gerar hipótese da aplicabilidade e benefício da taVNS na IC através da comparação intergrupos de parâmetros ecocardiográficos, teste de caminhada de 6 min, variabilidade da frequência cardíaca pelo Holter (SDNN e rMSSD), questionário de qualidade de vida de Minnesota e classe funcional pela New York Heart Association. Métodos Estudo clínico prospectivo, duplo cego, randomizado com metodologia sham, unicêntrico. Avaliados 43 pacientes e alocados em 2 grupos: o Grupo 1 recebeu taVNS (frequências 2/15 Hz) e Grupo 2 recebeu sham. Nas comparações, valores de p<0,05 foram considerados significativos. Resultados Na fase pós-intervenção, observou-se que o Grupo 1 se manteve com melhor rMSSD (31 x 21; p = 0,046) e atingiu melhor SDNN (110 vs. 84, p = 0,033). Ao compararmos os parâmetros intragrupos, antes e após intervenção, observou-se que todos melhoraram significativamente no grupo 1 e não houve diferenças no grupo 2. Conclusão A taVNS é uma intervenção segura, de fácil execução e que sugere provável benefício na IC pela melhora na variabilidade da frequência cardíaca, o que indica melhor equilíbrio autonômico. Novos estudos com maior número de pacientes são necessários para responder às questões levantadas por esse estudo.


Abstract Background The autonomic nervous system (ANS) imbalance in heart failure (HF) creates a vicious cycle, excess sympathetic activity, and decreased vagal activity contributing to the worsening of HF. Low-intensity transcutaneous electrical stimulation of the auricular branch of the vagus nerve (taVNS) is well tolerated and opens new therapeutic possibilities. Objectives To hypothesize the applicability and benefit of taVNS in HF through intergroup comparison of echocardiography parameters, 6-minute walk test, Holter heart rate variability (SDNN and rMSSD), Minnesota quality of life questionnaire, and functional class by the New York Heart Association. In comparisons, p values <0.05 were considered significant. Methods Prospective, double-blind, randomized clinical study with sham methodology, unicentric. Forty-three patients were evaluated and divided into 2 groups: Group 1 received taVNS (frequencies 2/15 Hz), and Group 2 received sham. In comparisons, p values <0.05 were considered significant. Results In the post-intervention phase, it was observed that Group 1 had better rMSSD (31 x 21; p = 0.046) and achieved better SDNN (110 vs. 84, p = 0.033). When comparing intragroup parameters before and after the intervention, it was observed that all of them improved significantly in group 1, and there were no differences in group 2. Conclusion taVNS is a safe to perform and easy intervention and suggests a probable benefit in HF by improving heart rate variability, which indicates better autonomic balance. New studies with more patients are needed to answer the questions raised by this study.

ABSTRACT

Resumo Fundamento A Insuficiência Cardíaca é um importante problema de saúde pública, que leva à alta carga de sintomas físicos e psicológicos, apesar da terapia otimizada. Objetivo Avaliar primariamente o impacto de um Programa de Redução de Estresse, Meditação e Atenção plena na redução do estresse de pacientes com Insuficiência Cardíaca. Métodos Ensaio clínico randomizado e controlado que avaliou o impacto de um programa de redução de estresse comparado ao atendimento multidisciplinar convencional, em dois centros especializados no Brasil. O período de coleta de dados ocorreu entre abril e outubro de 2019. Um total de 38 pacientes foram alocados nos grupos de intervenção ou controle. A intervenção aconteceu ao longo de 8 semanas. O protocolo consistiu na avaliação das escalas de estresse percebido, depressão, qualidade de vida, ansiedade, atenção plena, qualidade do sono, teste de 6 minutos de caminhada e biomarcadores por um grupo cego, considerando um p-valor <0,05 como estatisticamente significativo. Resultados A intervenção resultou em redução significativa no estresse percebido de 22,8 ± 4,3 para 14,3 ± 3,8 pontos na escala de estresse percebido no grupo de intervenção vs. 23,9 ± 4,3 para 25,8 ± 5,4 no grupo controle (p-valor<0,001). Foi observada melhora significativa na qualidade de vida (p-valor=0,013), atenção plena (p-valor=0,041), qualidade do sono (p-valor<0,001) e no teste de 6 minutos de caminhada (p-valor=0,004) no grupo sob intervenção comparado com o controle. Conclusão O Programa de Redução de Estresse, Meditação e Atenção plena reduziu efetivamente o estresse percebido e melhorou desfechos clínicos em pacientes com Insuficiência Cardíaca.


Abstract Background Heart Failure is a significant public health problem leading to a high burden of physical and psychological symptoms despite optimized therapy. Objective To evaluate primarily the impact of a Stress Reduction, Meditation, and Mindfulness Program on stress reduction of patients with Heart Failure. Methods A randomized and controlled clinical trial assessed the effect of a stress reduction program compared to conventional multidisciplinary care in two specialized centers in Brazil. The data collection period took place between April and October 2019. Thirty-eight patients were included and allocated to the intervention or control groups. The intervention took place over 8 weeks. The protocol assessed the scales of perceived stress, depression, quality of life, anxiety, mindfulness, quality of sleep, a 6-minute walk test, and biomarkers analyzed by a blinded team, considering a p-value <0.05 statistically significant. Results The intervention resulted in a significant reduction in perceived stress from 22.8 ± 4.3 to 14.3 ± 3.8 points in the perceived stress scale-14 items in the intervention group vs. 23.9 ± 4.3 to 25.8 ± 5.4 in the control group (p-value<0.001). A significant improvement in quality of life (p-value=0.013), mindfulness (p-value=0.041), quality of sleep (p-value<0.001), and the 6-minute walk test (p-value=0.004) was also observed in the group under intervention in comparison with the control. Conclusion The Stress Reduction, Meditation, and Mindfulness Program effectively reduced perceived stress and improved clinical outcomes in patients with chronic Heart Failure.

ABSTRACT

Resumo O raciocínio clínico nasceu 2500 anos atrás com Hipócrates, tendo evoluído ao longo dos séculos, e se tornado uma mistura de arte e ciência. Várias personalidades ao longo da história contribuíram para melhorar a acurácia diagnóstica. Contudo, o erro diagnóstico é ainda comum e causa um grande impacto nos sistemas de saúde. Para lidar com esse desafio, vários modelos de raciocínio clínico surgiram para sistematizar o processo de pensamento clínico. Este artigo descreve a história do raciocínio clínico e os métodos atuais de raciocínio diagnóstico, propõe um novo modelo de raciocínio clínico chamado Raciocínio Integrativo, e traz perspectivas sobre o futuro do raciocínio clínico.


Abstract Clinical reasoning was born 2,500 years ago with Hippocrates, having evolved over the centuries, becoming a mixture of art and science. Several personalities throughout history have contributed to improving diagnostic accuracy. Nonetheless, diagnostic error is still common and causes a severe impact on healthcare systems. To face this challenge, several clinical reasoning models have emerged to systematize the clinical thinking process. This paper describes the history of clinical reasoning and current diagnostic reasoning methods, proposes a new clinical reasoning model, called Integrative Reasoning, and brings perspectives about the future of clinical reasoning.

ABSTRACT

Abstract Background: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with heart failure. Objective: To evaluate the response of CRT in maximal inspiratory pressure (MIP), peak expiratory flow (PEF), and exercise tolerance as determined by the six-minute walk test (6MWT) in patients with HF. Methods: This study used the 6MWT and Manovacuometer to assess functional capacity in relation to activities of daily living, in which fatigue and dyspnea are common. Results: After six months of CRT, this study identified improvements in the 6MWT, p<0.05; MIP, p=0.01; and PEF, p=0.03. Conclusion: After CRT, this study showed a significant improvement in MIP, PEF, and exercise tolerance. However, further studies are warranted to demonstrate the relevance of these findings.

ABSTRACT

Resumo Fundamento O tecido adiposo epicárdico (TAE) é aumentado em comorbidades comuns na insuficiência cardíaca (IC). Dessa forma, o TAE teria o potencial de mediar efeitos que levam à deterioração da função cardíaca. Objetivos Esta metanálise tem o objetivo de investigar se a quantidade de TAE em todos os tipos de IC e cada tipo de IC são significativamente diferentes dos pacientes de controle. Métodos Esta metanálise seguiu as diretrizes da Meta-analysis of Observational Studies in Epidemiology (Metanálise de estudos observacionais em epidemiologia). A pesquisa foi realizada nos bancos de dados MEDLINE, Embase e Lilacs até novembro de 2020. Dois autores realizaram a triagem, a extração de dados e a avaliação de qualidade. Um p-valor <0,05 foi definido como estatisticamente significativo. Resultados Foram incluídos oito estudos observacionais, compreendendo 1248 pacientes no total, dos quais 574 eram de controle, 415 tinham IC com fração de ejeção reduzida (ICFER) e 259 tinham IC com fração de ejeção de faixa média ou preservada (ICFEfm ou ICFEP). A quantidade de TAE não era diferente entre todos os tipos de IC e o grupo de controle (DMP = -0,66, IC 95%: -1,54 a 0,23, p =0,14) . Analisando cada fenótipo de IC separadamente, pacientes com ICFER tinham TAE reduzido em comparação aos pacientes de controle (DMP = 1,27, IC 95%: - 1,87 a -0,67, p <0,0001), enquanto os pacientes com ICFEfm ou ICFEP tiveram TAE aumentado em comparação aos pacientes de controle (DMP = 1,24, IC 95%: 0,99 a 1,50, p <0,0001). Conclusão A quantidade de TAE não era significativamente diferente entre todos os tipos de IC e o grupo de controle. Em pacientes com ICFER o volume de TAE era reduzido, enquanto em pacientes com ICFEP e ICFEfm, a quantidade de TAE era significativamente aumentada. Número de registro PROSPERO: CRD42019134441.


Abstract Background Epicardial adipose tissue (EAT) is increased in comorbidities common in heart failure (HF). In this sense, EAT could potentially mediate effects that lead to an impaired cardiac function. Objectives This meta-analysis aims to investigate if the amount of EAT in all-types of HF and each HF phenotype is significantly different from control patients. Methods This meta-analysis followed the Meta-analysis Of Observational Studies in Epidemiology guidelines. The search was performed in the MEDLINE, Embase, and Lilacs databases until November 2020. Two authors performed screening, data extraction, and quality assessment. A p-value <0.05 was defined as statistically significant. Results Eight observational studies were included, comprehending 1,248 patients in total, from which 574 were controls, 415 had HF with reduced ejection fraction (HFrEF) and 259 had HF with mid-range or preserved ejection fraction (HFmrEF or HFpEF). The amount of EAT was not different between all types of HF and the control group (SMD = -0.66, 95% CI: -1.54 to 0.23, p =0.14). Analyzing each HF phenotype separately, patients with HFrEF had a reduced EAT when compared to the controls (SMD= -1.27, 95% CI: - 1.87 to -0.67, p <0.0001), while patients with HFmrEF or HFpEF showed an increased EAT when compared to controls (SMD= 1.24, 95% CI: 0.99 to 1.50, p <0.0001). Conclusion The amount of EAT was not significantly different between all types of HF and the control group. In patients with HFrEF, the EAT volume was reduced, whereas in HFpEF and HFmrEF, the amount of EAT was significantly increased. PROSPERO registration number: CRD42019134441.

ABSTRACT

Abstract Background: Despite optimal medical treatment, many heart failure (HF) patients continue to show a high prevalence of symptoms, which contributes to a high morbidity and poor health-related quality of life (HRQL). Mindfulness meditation may be effective in improving the quality of life in these patients. Objective: A systematic review was conducted to evaluate if mindfulness meditation programs are effective in promoting and improving the quality of life in patients with heart failure. Methods: The PubMed (MEDLINE), Cumulative Index of Nursing and Allied Health (CINAHL), LILACS, Cochrane Library, and Scopus databases were searched between October and November of 2019. Articles were selected if they evaluated mindfulness intervention, with an experimental or quasi-experimental design, in adults with heart failure and measured health-related quality of life. Results: This systematic review identified 108 studies through database searches. After applying the inclusion and exclusion criteria, a total of three studies were considered qualified. These studies took place in the Netherlands, the USA, and Brazil, and occurred between 2005 and 2015. Sample sizes varied from 19 to 215, and the average range of participants within each study varied from 43.2 to 75.4 years. Compared to control programs, mindfulness-based meditation programs improved the quality of life in two studies (p= 0.041 and p=0.03). Conclusion: Mindfulness-based meditation programs improved the quality of life in patients with HF. Therefore, there is limited data to strengthen this recommendation to this population, and future research is warranted in order to present consistency in the intervention protocols.

ABSTRACT

Resumo Fundamento: A proteína C-reativa (PCR) é um biomarcador de inflamação preditor de eventos adversos em procedimentos cardiovasculares. Na avaliação do implante da válvula aórtica transcateter (transcatheter aortic valve implantation, TAVI) em relação ao prognóstico de longo prazo ainda é incipiente. Objetivo: Avaliar a PCR como marcador prognóstico no primeiro ano pós-TAVI na estenose aórtica (EAo). Métodos: A PCR foi avaliada na primeira semana do peroperatório numa coorte de casos retrospectiva com EAo. Correlacionou-se a PCR pré- e pós-TAVI com a mortalidade e foram pesquisados fatores preditores de mortalidade em 1 ano. Realizada regressão de Cox multivariada para identificar os preditores independentes de óbito em 1 ano. Resultados: Estudados 130 pacientes submetidos a TAVI, com mediana de idade de 83 anos, sendo 49% deles do sexo feminino. A PCR pré-TAVI elevada (> 0,5 mg/dL) ocorreu em 34,5% dos casos. O pico de PCR foi 7,0 (5,3-12,1) mg/dL no quarto dia. A mortalidade em 1 ano foi 14,5% (n = 19), sendo maior nos grupos com PCR pré-TAVI elevada (68,8% vs 29,1%; p = 0,004) e pico de PCR ≥ 10,0 mg/dL (64,7% vs 30,8%; p = 0,009). Os fatores preditores independentes de mortalidade foram insuficiência renal aguda (IRA) [razão de risco (RR) = 7,43; intervalo de confiança de 95% (IC95%), 2,1-24,7; p = 0,001], PCR pré-TAVI elevada [RR = 4,15; IC95%, 1,3-12,9; p=0,01] e hemotransfusão volumosa [HR = 4,68; 1,3-16,7; p = 0,02]. Conclusões: A PCR pré-TAVI elevada mostrou-se fator preditor independente de mortalidade no primeiro ano, assim como a ocorrência de IRA e hemotransfusões volumosas.


Abstract Background: C-reactive protein (CRP) is an inflammation biomarker that can be a predictor of adverse events in cardiovascular procedures. Its use in the assessment of long-term prognosis of transcatheter aortic valve implantation (TAVI) is still incipient. Objective: To evaluate CRP as a prognostic marker in the first year after TAVI in aortic stenosis (AoS). Methods: CRP was assessed on the first postoperative week in a retrospective cohort of patients with AoS. Pre- and post- CRP levels were correlated with mortality, and predictors of 1-year mortality were investigated. Multivariate Cox regression was performed to identify independent factors of 1-year mortality. Results: This study evaluated 130 patients who underwent TAVI, with median age of 83 years, and 49% of women. High pre-TAVI CRP (> 0.5 mg/dL) was observed in 34.5% of the cases. Peak CRP was 7.0 (5.3-12.1) mg/dL no quarto dia. The rate of 1-year mortality was 14.5% (n = 19), being greater in the groups with high pre-TAVI CRP (68.8% vs 29.1%; p = 0,004) and with peak CRP ≥ 10.0 mg/dL (64.7% vs 30.8%; p = 0,009). Independent predictors of mortality were acute renal failure (ARF) (hazard ratio [HR] = 7.43; 95% confidence interval [95%CI], 2.1-24.7; p = 0,001), high pre-TAVI CRP (HR 4.15; 95%CI, 1.3-12.9; p = 0.01), and large blood transfusion [HR 4,68; 1,3-16,7; p = 0.02]. Conclusions: High pre-TAVI CRP showed to be an independent predictor of 1-year mortality, as well as the presence of ARF and large blood transfusions.

ABSTRACT

Abstract This is an article aimed at showing the mentoring role in a fast-changing society, particularly during and after the COVID-19 pandemic. The intense flow of information feelings and new knowledge makes it necessary for medical education to be updated to keep up with social and professional dynamics, according to health requirements and new knowledge demands. The mentoring program is a development process in which the mentor promotes the mentee professional and personal growth, by the exchange of visions and experiences. It allows an increase in the repertoire of solutions, particularly important in such an unstable context imposed by the pandemic. The mentor and mentee are challenged to move from a traditional to a virtual environment, characterized by physical distancing, development of digital medicine and distance learning.

ABSTRACT

Resumo Aproximadamente 300 milhões de cirurgias não cardíacas são realizadas anualmente no mundo, e eventos cardiovasculares adversos são as principais causas de morbimortalidade no período perioperatório e pós-operatório. A lesão miocárdica após cirurgia não cardíaca (MINS, do inglês myocardial injury after non-cardiac surgery) é uma nova entidade clínica associada com desfechos cardiovasculares adversos. MINS é definida como uma lesão miocárdica que pode resultar em necrose secundária à isquemia, com elevação dos biomarcadores. A lesão tem importância prognóstica e ocorre em até 30 dias após a cirurgia não cardíaca. Os critérios diagnósticos para MINS são: níveis elevados de troponina durante ou em até 30 dias após a cirurgia não cardíaca, sem evidência de etiologia não isquêmica, sem que haja necessariamente sintomas isquêmicos ou achados eletrocardiográficos de isquemia. Recentemente, pacientes com maior risco para MINS têm sido identificados por variáveis clínicas e biomarcadores, bem como por protocolos de vigilância quanto ao monitoramento eletrocardiográfico e dosagem de troponina cardíaca. Pacientes idosos com doença aterosclerótica prévia necessitam medir troponina diariamente no período pós-operatório. O objetivo deste trabalho é descrever este novo problema de saúde pública, seu impacto clínico e a abordagem terapêutica contemporânea.


Abstract Approximately 300 million non-cardiac surgeries are performed annually worldwide and adverse cardiovascular events are the main cause of morbidity and mortality in the peri- and postoperative period. Myocardial injury after non-cardiac surgery (MINS) is a new clinical entity associated with adverse cardiovascular outcomes. MINS is defined as myocardial injury that can result in necrosis due to ischemia, marked by increase in biomarker levels. It has prognostic relevance and occurs within up to 30 days after non-cardiac surgery. The diagnostic criteria for MINS are an elevated postoperative measure of troponin judged as secondary to myocardial ischemia, i.e., with no evidence of a non-ischemic etiology, during or within 30 days after non-cardiac surgery, and without the requirement of an ischemic symptom or electrocardiographic finding of ischemia. Recently, patients at higher risk for MINS have been recognized using clinical variables and biomarkers and established protocols for greater surveillance in relation to electrocardiographic monitoring and cardiac troponin dosage. Elderly patients with previous atherosclerotic disease need to measure troponin daily in the postoperative period. The aim of the present work is to describe this new public health problem, its clinical impact and contemporary therapeutic approach.
