RESUMO

BACKGROUND: Heart Failure with mid-range Ejection Fraction (HFmEF) was recently described by European and Brazilian guidelines on Heart Failure (HF). The ejection fraction (EF) is an important parameter to guide therapy and prognosis. Studies have shown conflicting results without representative data from developing countries. OBJECTIVE: To analyze and compare survival rate in patients with HFmEF, HF patients with reduced EF (HFrEF), and HF patients with preserved EF (HFpEF), and to evaluate the clinical characteristics of these patients. METHODS: A cohort study that included adult patients with acute HF admitted through the emergency department to a tertiary hospital, reference in cardiology, in south Brazil from 2009 to 2011. The sample was divided into three groups according to EF: reduced, mid-range and preserved. A Kaplan-Meier curve was analyzed according to the EF, and a logistic regression analysis was done. Statistical significance was established as p < 0.05. RESULTS: A total of 380 patients were analyzed. Most patients had HFpEF (51%), followed by patients with HFrEF (32%) and HFmEF (17%). Patients with HFmEF showed intermediate characteristics related to age, blood pressure and ventricular diameters, and most patients were of ischemic etiology. Median follow-up time was 4.0 years. There was no statistical difference in overall survival or cardiovascular mortality (p=.0031) between the EF groups (reduced EF: 40.5% mortality; mid-range EF 39.7% and preserved EF 26%). Hospital mortality was 7.6%. CONCLUSION: There was no difference in overall survival rate between the EF groups. Patients with HFmEF showed higher mortality from cardiovascular diseases in comparison with HFpEF patients. (Arq Bras Cardiol. 2021; 116(1):14-23).

RESUMO

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

RESUMO

OBJECTIVES: To describe the prevalence of the reduced ankle-brachial index (ABI) in patients with heart failure (HF) with preserved ejection fraction (HFpEF) attended at a HF clinic in the metropolitan region of Porto Alegre, and to compar the patients to those with reduced ejection fraction (HFrEF). METHODS: A descriptive observational study, included patients referred to the heart failure clinic in HU-Ulbra with HFpEF or HFrEF and diastolic dysfunction, and measurements of ABIs using vascular Doppler equipment were performed in both groups. RESULTS: The sample consisted of 106 patients with HF, 53.9% of the patients had HFpEF, and 19.4% had a diagnosis of peripheral arterial disease (PAD) (ABI less than 0.9). PAD was identified in 24.1% of the patients with HFpEF, while15.8% of patients in the HFrEF group were diagnosed with PAD. CONCLUSION: Our results did not identify a significantly different prevalence of altered and compatible PAD values in patients with HFpEF. However, we showed a prevalence of 19.4%, a high value if we consider similar populations.

RESUMO

BACKGROUND: Current therapies for heart failure (HF) are followed by strategies to improve quality of life and exercise tolerance, besides reducing morbidity and mortality. Some HF patients present changes in the musculoskeletal system and inspiratory muscle weakness, which may be restored by inspiratory muscle training, thus increasing respiratory muscle strength and endurance, maximal oxygen uptake (VO2), functional capacity, respiratory responses to exercise, and quality of life. Yoga therapies have been shown to improve quality of life, inflammatory markers, and peak VO2 mostly in HF patients with a reduced ejection fraction. However, the effect of different yoga breathing techniques in patients showing HF with a preserved ejection fraction (HFpEF) remain to be assessed. METHODS/DESIGN: A PROBE (prospective randomized open blinded end-point) parallel-group trial will be conducted at two specialized HF clinics. Adult patients previously diagnosed with HFpEF will be included. After signing informed consent and performing a pre-test intervention, patients will be randomized into three groups and provided with either (1) active yoga breathing techniques; (2) passive yoga breathing techniques (pranayama); or and (3) control (standard pharmacological treatment). Follow-up will last 8 weeks (16 sessions). The post-intervention tests will be performed at the end of the intervention period for analysis of outcomes. Interventions will occur continuously according to patients' enrollment. The main outcome is respiratory muscular resistance. A total of 33 enrolled patients are expected. The present protocol followed the SPIRIT guidelines and fulfilled the SPIRIT checklist. DISCUSSION: This trial is probably the first to assess the effects of a non-pharmacological intervention, namely yoga and specific breathing techniques, to improve cardiorespiratory function, autonomic system, and quality of life in patients with HFpEF.

RESUMO

OBJECTIVE: Rhythm abnormalities following transcatheter aortic valve implantation (TAVI) and indications for permanent pacemaker implantation (PPI) were reviewed, which aren't well established in the current guidelines. New left bundle branch block and atrioventricular block are the most common electrocardiographic changes after TAVI. PPI incidence ranges from 9-42% for self-expandable and 2.5-11.5% for balloon expandable devices. Not only anatomical variations in conduction system have an important role in conduction disorders, but different valve characteristics and their relationship with cardiac structures as well. Previous right bundle branch block has been confirmed as one of the most significant predictors for PPI.

RESUMO

Fundamento: A Doença Arterial Periférica (DAP) está associada a eventos cardiovasculares, podendo ser diagnosticada e estimada através do Índice Tornozelo-Braquial (ITB). Está bem estabelecido que o ITB é fator agravante na estratificação de risco cardiovascular, mas sua contribuição para definir a gravidade do acometimento arterial coronariano não está bem estabelecida. Objetivos: Estudo testou o valor do ITB com a gravidade da doença aterosclerótica coronariana pelo Escore de Syntax (ES) em pacientes com Síndrome Coronariana Aguda (SCA). Métodos: Estudo prospectivo com medida do ITB de todos os pacientes internados com SCA no Hospital São Lucas da PUCRS, consecutivamente, de maio a setembro de 2016, e comparação de seu valor com o ES e tipos de SCA desses pacientes. As análises foram realizadas considerando-se o nível de confiança de 95% ( α = 5%). Resultados: 101 pacientes, com média de idade de 62,6±12,0 anos, 58 (57,4%) masculinos, 74 (82,2%) hipertensos, 33 (45,8%) diabéticos e 46 (45,5%) com infarto agudo do miocárdio com supradesnivelamento do ST (IAMCSST). A gravidade da DAP não teve relação com a gravidade anatômica da doença arterial coronariana (DAC). Encontramos uma associação significativa de ES intermediário com infarto agudo do miocárdio sem supradesnivelamento do ST (IAMSSST) e de ES baixo com angina instável (AI) [OR (IC95%): 1,11 (1,03-1,20); p = 0,004], que se manteve após análise multivariada, ajustada para idade, tabagismo, história familiar de DAC e DAC prévia [OR (IC95%): 1,13 (1,02-1,25); p = 0,019]. Conclusões: Analisando nossos resultados, encontramos que pacientes com ITB < 0,9 não apresentaram associação com maior complexidade determinada pelo ES em pacientes com SCA. Os pacientes com IAMSSST estiveram mais associados com ES intermediário

Abstract Background: Peripheral Artery Disease (PAD) is associated with cardiovascular events and can be diagnosed and estimated by use of the Ankle-Brachial Index (ABI). ABI is a worsening factor in the stratification of cardiovascular risk, but its contribution to define the severity of coronary artery disease has not been well established. Objectives: To compare the ABI value with the coronary atherosclerotic disease severity by use of the Syntax Score (SS) in patients with Acute Coronary Syndrome (ACS). Methods: This prospective study measured the ABI of all patients with ACS consecutively admitted to the São Lucas Hospital of PUCRS from May to September 2016, and compared the ABI values with the SS and ACS types of those patients. The analyzes were performed considering the 95%confidence interval ( α = 5%). Results: This study assessed 101 patients [mean age, 62.6 ± 12.0 years; 58 men (57.4%)], 74 (82.2%) were hypertensive, 33 (45.8%) had diabetes and 46 (45,5%) had ST-elevation acute myocardial infarction (STEMI). The PAD severity was not related to the anatomical severity of the coronary artery disease (CAD). We found a significant association of intermediate SS with non-ST-elevation acute myocardial infarction (NSTEMI), and of low SS with unstable angina (UA) [OR (95% CI): 1.11 (1.03-1.20) (p = 0.004)], which remained after multivariate analysis adjusted to age, smoking, family history of CAD and previous CAD [(OR 95%): 1.13 (1.02-1.25) (p = 0.019)]. Conclusions: Patients with ABI < 0.9 showed no association with higher disease complexity determined by the SS in patients with ACS. Patients with NSTEMI were more associated with an intermediate risk on the SS

RESUMO

BACKGROUND: Advances in juvenile idiopathic arthritis (JIA) treatment is promoting free disease survival. Cardiovascular disease (CVD) may emerge as an important cause of morbidity and mortality. Pulse wave velocity (PWV), a surrogate marker of arterial stiffness, and telomere length (TL) are considered as potential predictors of CVD and its outcomes. The study aim was to assess PWV, TL in a JIA population and to test its correlation. In a cross sectional study, 24 JIA patients, 21 controls for TL and 20 controls for PWV were included. PWV was assessed by an oscillometric device. TL was assessed by qPCR. JIA activity was accessed by JADAS-27. Smoking, diabetes, obesity, renal impairment, hypertension, dyslipidemia and inflammatory diseases were excluded. FINDINGS: Between cases and controls for TL, there was significant difference in age. No differences in gender, ethnics and bone mass index between JIA and control groups for PWV and TL. The JADAS-27 median was 8. TL was significantly reduced in JIA (0.85 ± 0.34 vs. 1. 67 ± 1.38, P = 0.025). When age adjusted by ANCOVA, the difference remained significant (P = 0,032). PWV was normal in all patients (5.1 ± 0.20 m/s vs. 4.98 ± 0.06 m/s, P = 0, 66). There was no correlation between TL, PWV or JADAS-27. CONCLUSION: Compared to controls, JIA with high disease activity and no CVD risk factors have shorter telomeres and normal PWV. As far as we know, this first time this correlation is being tested in rheumatic disease and in paediatrics.

RESUMO

AbstractBackground:Heart failure with preserved ejection fraction is a syndrome characterized by changes in diastolic function; it is more prevalent among the elderly, women, and individuals with systemic hypertension (SH) and diabetes mellitus. However, in its early stages, there are no signs of congestion and it is identified in tests by adverse remodeling, decreased exercise capacity and diastolic dysfunction.Objective:To compare doppler, echocardiographic (Echo), and cardiopulmonary exercise test (CPET) variables - ergospirometry variables - between two population samples: one of individuals in the early stage of this syndrome, and the other of healthy individuals.Methods:Twenty eight outpatients diagnosed with heart failure according to Framingham’s criteria, ejection fraction > 50% and diastolic dysfunction according to the european society of cardiology (ESC), and 24 healthy individuals underwent Echo and CPET.Results:The group of patients showed indexed atrial volume and left ventricular mass as well as E/E’ and ILAV/A´ ratios significantly higher, in addition to a significant reduction in peak oxygen consumption and increased VE/VCO2 slope, even having similar left ventricular sizes in comparison to those of the sample of healthy individuals.Conclusion:There are significant differences between the structural and functional variables analyzed by Echo and CPET when comparing two population samples: one of patients in the early stage of heart failure with ejection fraction greater than or equal to 50% and another of healthy individuals.


ResumoFundamento:Insuficiência cardíaca com fração de ejeção preservada é uma síndrome caracterizada por alterações da função diastólica mais prevalente em idosos, mulheres e portadores de hipertensão arterial sistêmica (HAS) e diabete melito. No início, entretanto, não revela sinais de congestão, identificando-se por remodelamento adverso, diminuição da capacidade de exercício e disfunção diastólica nos exames.Objetivo:Comparar variáveis ecocardiográficas e de doppler (Eco) e do teste cardiopulmonar de exercício (TCPE) - ergoespirométricas - entre duas amostras populacionais: indivíduos portadores dessa síndrome em estágio inicial e outra de saudáveis.Métodos:Vinte e oito pacientes ambulatoriais com diagnóstico de insuficiência cardíaca por critérios de Framingham, fração de ejeção > 50% e disfunção diastólica segundo a european society of cardiology (ESC), e 24 indivíduos saudáveis realizaram estudos de Eco e TCPE.Resultados:O grupo de pacientes apresentou volume atrial e massa ventricular esquerda indexadas, bem como as razões E/E’ e VAEi/A´ significativamente maiores, além de significativa redução do consumo máximo de oxigênio e incremento da inclinação da variável VE/VCO2, mesmo com semelhantes dimensões do ventrículo esquerdo, quando comparados à amostra dos saudáveis.Conclusão:Há diferenças significativas entre variáveis estruturais e funcionais analisadas nos estudos ao Eco e ao TCPE, comparando-se duas amostras populacionais: pacientes com estágio inicial de insuficiência cardíaca com fração de ejeção maior ou igual a 50% e outra de indivíduos saudáveis.

RESUMO

OBJECTIVES: Atrial fibrillation is the most common sustained arrhythmia and is associated with poor outcomes, including stroke. The ability of anticoagulation therapy to reduce the risk of stroke has been well established; however, the prevalence of anticoagulation therapy use in the Public Health System is unknown. The aim of this study is to evaluate both the prevalence of anticoagulation therapy among patients with atrial fibrillation and the indications for the treatment. METHODS: In this cross-sectional study, we included consecutive patients who had atrial fibrillation documented by an electrocardiogram performed between September 2011 and March 2012 at a university hospital of the Public Health System. The variables analyzed included the risk of a thromboembolic event and/or bleeding, the use of antiplatelet or anticoagulation therapy, the location where the electrocardiogram report was initially reviewed and the specialty of the physician who initially reviewed it. RESULTS: We included 162 patients (mean age 68.9 years, 56% men). Hypertension (90.1%), heart failure (53.4%) and stroke (38.9%) were the most prevalent diseases found. Only 50.6% of the patients knew that they had atrial fibrillation. Regarding the use of therapy, only 37.6% of patients classified as high risk according to the CHADS2 scores and 35.5% according to the CHA2DS2VASc used oral anticoagulation. A presumptive diagnosis of heart failure and the fact that the electrocardiogram was evaluated by a cardiologist were the only independent predictors of the use of anticoagulants. CONCLUSIONS: Our study found a low prevalence of oral anticoagulation therapy among patients with atrial fibrillation and an indication for stroke prophylaxis for the use of this therapy, including among those with high CHADS2 and CHA2DS2VASc scores.

The variables analyzed included the risk of a thromboembolic event and/or bleeding, the use of antiplatelet or anticoagulation therapy, the location where the electrocardiogram report was initially reviewed and the specialty of the physician who initially reviewed it. RESULTS: We included 162 patients (mean age 68.9 years, 56% men). Hypertension (90.1%), heart failure (53.4%) and stroke (38.9%) were the most prevalent diseases found. Only 50.6% of the patients knew that they had atrial fibrillation. Regarding the use of therapy, only 37.6% of patients classified as high risk according to the CHADS2 scores and 35.5% according to the CHA2DS2VASc used oral anticoagulation. A presumptive diagnosis of heart failure and the fact that the electrocardiogram was evaluated by a cardiologist were the only independent predictors of the use of anticoagulants. CONCLUSIONS: Our study found a low prevalence of oral anticoagulation therapy among patients with atrial fibrillation and an indication for stroke prophylaxis for the use of this therapy, including among those with high CHADS2 and CHA2DS2VASc scores. .

RESUMO

Introdução: As doenças cardiovasculares têm ampla prevalência e no Brasil são responsáveis pela terceira maior causa de internações do SUS sendo a a insuficiência cardíaca (IC) a principal razão. O presente estudo visa comparar as características antropométricas e presença de diferentes comorbidades em pacientes ambulatoriais com IC crônica, analisando as diferenças entre dois grupos, dicotomizados pela preservação ou comprometimento da fração de ejeção (FE). Métodos: Estudo observacional de pacientes com IC crônica atendidos na região metropolitana de Porto Alegre (RS). Os pacientes foram divididos em dois grupos de FE, preservada (FER ≥ 50 %) ou reduzida (FER ≤ 50%), de um total de 155 pacientes atendidos entre julho de 2010 e junho de 2011. Análise estatística: As variáveis contínuas foram apresentadas por média e desvio padrão e as categóricas por frequência. As diferenças entre as variáveis continuas foram aferidas pelo teste T de Student, e, entre as categóricas, pelo teste do qui-quadrado, e consideradas estatisticamente significativas quando p≤0,05. Resultados: Na amostra, 48 pacientes apresentavam FEP, sendo 60,4% do sexo feminino, com índice de massa corporal médio de 32,8 Kg/m2SC e circunferência abdominal e quadril com médias de 105,7 cm e 107,9 cm, respectivamente, que foram significativamente maiores do que no grupo com FER, além de níveis pressóricos sistólicos mais elevados. Conclusão: Os pacientes com FEP, na amostra estudada, foram significativamente mais obesos e com maior distribuição de gordura centrípeta, sem outras diferenças antropométricas, e com média de PA sistólica mais elevada, quando comparados aos pacientes com FER.


Introduction: Cardiovascular diseases are widely prevalent and in Brazil they are the third leading cause of SUS hospitalizations where heart failure (HF) is the main reason. This study aims to compare the anthropometric characteristics and presence of various co-morbidities in outpatients with chronic HF, analyzing the differences between two groups, dichotomized by preservation or impairment of the ejection fraction (EF). Methods: An observational study of patients with chronic heart failure treated in the metropolitan region of Porto Alegre (RS). The patients were divided into two groups of EF, preserved (PEF ≥ 50%) or reduced (REF ≤ 50%), from a total of 155 patients treated between July 2010 and June 2011. Statistical analysis: Continuous variables were presented as mean and standard deviation and categorical variables by frequency. Differences between continuous variables were assessed by the Student’s t test, and between categorical variables by the chi-square test, and considered statistically significant at p ≤ 0.05. Results: In the sample, 48 patients had PEF, 60.4% being females, with a mean body mass index of 32.8 Kg/m2SC and mean waist circumference and hip of 105.7 cm and 107.9 cm, respectively, which were significantly higher than in the REF group, and higher systolic blood pressure. Conclusion: In our sample, patients with PEF were significantly more obese and had more centripetal fat distribution, with no other anthropometric differences, and higher mean systolic BP than patients with REF.

RESUMO

A Síndrome Metabólica (SM) caracteriza-se como um distúrbio complexo representado por um conjunto de fatores de risco cardiovascular, tendo sua frequência estimada entre 20% a 25% da população adulta mundial. Os diversos componentes da SM são responsáveis por alterações estruturais e funcionais de grandes artérias, dentre as quais destaca-se a diminuição da complacência arterial como um importante marcador de risco cardiovascular. A medida da Velocidade de Onda de Pulso (VOP) configura-se como um método relevante na avaliação da rigidez arterial. Discute-se, nesta revisão, os principais mecanismos pelos quais os componentes da SM atuam provocando estas alterações vasculares, a relevância destas modificações e o reflexo da influência terapêutica nestes casos. A revisão bibliográfica foi realizada através de consulta às bases de dados eletrônicos Medline, Lilacs e Pubmed, entre os anos de 2008 e 2009. Foram utilizados os descritores “metabolic syndrome”, “pulse wave velocity” e “arterial stiffness”, nos idiomas português e inglês, sendo selecionados estudos datados entre 1962 e 2009. Observou-se através dos estudos revisados que os componentes da SM atuam através de diferentes mecanismos para promover o aumento da VOP. A principal alteração vascular relacionada a estes componentes foi a diminuição da complacência das grandes artérias. A avaliação da complacência arterial através da medida da VOP permite o acompanhamento dos resultados obtidos através das intervenções terapêuticas e a identificação precoce destas alterações vasculares. Desta forma, torna-se possível a adoção de uma medida terapêutica precoce, possibilitando diminuir significativamente a progressão destas alterações vasculares e, portanto, reduzir a mortalidade cardiovascular destes pacientes.


The metabolic syndrome (MS) is characterized as a complex disorder represented by a set of cardiovascular risk factors, its frequency estimated between 20% to 25% of the adult population worldwide. The various components of MS are responsible for structural and functional alterations of large arteries, among which a decrease in arterial compliance stands out as an important cardiovascular risk marker. Measurement of Pulse Wave Velocity (PWV) figures as a relevant method in the evaluation of arterial stiffness. This review discusses the main mechanisms by which components of MS act causing these vascular changes, the relevance of these changes and the reflex of treatment influence in these cases. A literature review was conducted by consulting electronic databases Medline, Pubmed and Lilacs between years 2008 and 2009. Metabolic syndrome, pulse wave velocity and arterial stiffness, and their Portuguese equivalents, were the search words used, selecting studies dating from 1962 to 2009. The reviewed studies showed that the components of MS act through different mechanisms to promote the increase of PWV. The main change related to these vascular components was decreased compliance of large arteries. Assessment of arterial compliance by measuring PWV allows tracking the results obtained through therapeutic interventions and early identification of these vascular changes. It thus becomes possible to adopt an early treatment measure, which allows to slow down the progression of these vascular changes significantly and therefore reduce cardiovascular mortality in these patients.
