RESUMO

OBJECTIVE: To assess the quality of life related to health for heart failure patients and to relate sociodemographic and clinical data. METHOD: It is an observational and transversal study, with quantitative approach, carried out in a heart failure ambulatory in the state of Pernambuco. RESULTS: In the sample (n=101), there was prevalence of men older than 60 years old, married and professionally inactive. The quality of life related to health, based on the Minnesota Living With Heart Failure Questionnaire, was considered moderate (34.3±21.6), being significantly related to age (p=0.004), functional class (p<0.001), and patients with chagasic cardiopathy (p=0.02). CONCLUSION: The quality of life in the HF group of chagasic etiology was more compromised, specially in the emotional dimension. It is suggested that studies on the hypothesis that longer ambulatory follow-up improves quality of life and that having Chagas disease interferes negatively with the quality of life of heart failure patients.

RESUMO

Abstract Background: Left ventricular global longitudinal strain value (GLS) can predict functional capacity in patients with preserved left ventricular ejection fraction (LVEF) heart failure (HF) and to assess prognosis in reduced LVEF HF. Objetive: Correlate GLS with parameters of Cardiopulmonary Exercise Test (CPET) and to assess if they could predict systolic HF patients that are more appropriated to be referred to heart transplantation according to CPET criteria. Methods: Systolic HF patients with LVEF < 45%, NYHA functional class II and III, underwent prospectively CPET and echocardiography with strain analysis. LVEF and GLS were correlated with the following CPET variables: maxVO2, VE/VCO2 slope, heart rate reduction during the first minute of recovery (HRR) and time needed to reduce maxVO2 in 50% after physical exercise (T1/2VO2). ROC curve analysis of GLS to predict VO2 < 14 mL/kg/min and VE/VCO2 slope > 35 (heart transplantation's criteria) was performed. Results: Twenty six patients were selected (age, 47 ± 12 years, 58% men, mean LVEF = 28 ± 8%). LVEF correlated only with maxVO2 and T1/2VO2. GLS correlated to all CPET variables (maxVO2: r = 0.671, p = 0.001; VE/VCO2 slope: r = -0.513, p = 0.007; HRR: r = 0.466, p = 0.016, and T1/2VO2: r = -0.696, p = 0.001). GLS area under the ROC curve to predict heart transplantation's criteria was 0.88 (sensitivity 75%, specificity 83%) for a cut-off value of -5.7%, p = 0.03. Conclusion: GLS was significantly associated with all functional CPET parameters. It could classify HF patients according to the functional capacity and may stratify which patients have a poor prognosis and therefore to deserve more differentiated treatment, such as heart transplantation.


Resumo Fundamento: O strain longitudinal global (SLG) é capaz de predizer a capacidade funcional dos pacientes com insuficiência cardíaca (IC) e fração de ejeção do ventrículo esquerdo (FEVE) preservada, e avaliar o prognóstico na IC com FEVE reduzida. Objetivo: Correlacionar o SLG com parâmetros do teste de exercício cardiopulmonar (TECP), e avaliar se o SLG seria capaz de predizer quais pacientes com IC sistólica deveriam ser encaminhados ao transplante cardíaco de acordo com os critérios do TECP. Métodos: Os pacientes com IC sistólica com FEVE <45%, classe funcional NYHA II e III, submeteram-se prospectivamente ao TECP e à ecocardiografia com análise do strain. A FEVE e o SLG foram correlacionados com as seguintes variáveis do TECP: maxVO2, inclinação de VE/VCO2, redução da frequência cardíaca durante o primeiro minuto de recuperação (RFC), e tempo necessário para a redução do maxVO2 em 50% após o exercício físico (T1/2VO2). Foi realizada análise da curva ROC do SLG em predizer um VO2 < 14 mL/kg/min e uma inclinação de VE/VCO2 > 35 (critérios para transplante cardíaco). O nível de significância adotado na análise estatística foi de p < 0,05. Resultados: Vinte e seis pacientes foram selecionados para o estudo (idade, 47±12 anos, 58% homens, FEVE média LVEF = 28 ± 8%). A FEVE correlacionou-se somente com o maxVO2 e o T1/2VO2. O SLG correlacionou-se com todas as variáveis do TECP (maxVO2: r = 0,671; p = 0,001; inclinação de VE/VCO2: r = -0,513; p = 0,007; RFC: r = 0,466; p = 0,016; e T1/2VO2: r = -0,696, p = 0,001). A área sob a curva ROC para o SLG para predizer os critérios para transplante cardíaco foi de 0,88 (sensibilidade 75%, especificidade 83%) para um ponto de corte de -5,7%, p = 0,03. Conclusão: O SLG apresentou associação significativa com todos os parâmetros funcionais do TECP. O SLG foi capaz de classificar os pacientes com IC segundo capacidade funcional e possivelmente pode identificar quais pacientes têm um prognóstico ruim e, portanto, se beneficiariam de um tratamento diferenciado, tal como o transplante cardíaco.

RESUMO

OBJECTIVE: To describe the precipitating factors of heart failure decompensation between adherent and non-adherent patients to treatment. METHODS: Cross-sectional study of a multicenter cohort study. Patients over 18 years of age with decompensated heart failure (functional class III/IV) were eligible. The structured questionnaire was used to collect the data and evaluate the reasons for decompensation. The irregular use of medication prior to hospitalization and inadequate salt and fluid intake were considered as poor adherence to treatment. RESULTS: A total of 556 patients were included, mean age 61 ± 14 years old, 362 (65%) male. The main factor of decompensation was poor adherence, representing 55% of the sample. Patients who reported irregular use of medications in the last week had a 22% greater risk of being hospitalized due to poor adherence than the patients who adhered to treatment. CONCLUSION: The EMBRACE study showed that in patients with heart failure, poor adherence was the main factor of exacerbation.

RESUMO

Abstract Background: Chagas Disease (CD) is an important cause of morbimortality due to heart failure and malignant arrhythmias worldwide, especially in Latin America. Objective: To investigate the association of obstructive sleep apnea (OSA) with heart remodeling and cardiac arrhythmias in patients CD. Methods: Consecutive patients with CD, aged between 30 to 65 years old were enrolled. Participants underwent clinical evaluation, sleep study, 24-hour Holter monitoring, echocardiogram and ambulatory blood pressure monitoring. Results: We evaluated 135 patients [age: 56 (45-62) years; 30% men; BMI: 26 ± 4 kg/m2, Chagas cardiomyopathy: 70%]. Moderate to severe OSA (apnea-hypopnea index, AHI, ≥ 15 events/h) was present in 21% of the patients. OSA was not associated with arrhythmias in this population. As compared to patients with mild or no OSA, patients with moderate to severe OSA had higher frequency of hypertension (79% vs. 72% vs. 44%, p < 0.01) higher nocturnal systolic blood pressure: 119 ± 17 vs. 113 ± 13 vs. 110 ± 11 mmHg, p = 0.01; larger left atrial diameter [37 (33-42) vs. 35 (33-39) vs. 33 (30-36) mm, p < 0.01]; and a greater proportion of left ventricular dysfunction [LVEF < 50% (39% vs. 28% vs. 11%), p < 0.01], respectively. Predictor of left atrial dimension was Log10 (AHI) (b = 3.86, 95% CI: 1.91 to 5.81; p < 0.01). Predictors of ventricular dysfunction were AHI > 15 events/h (OR = 3.61, 95% CI: 1.31 - 9.98; p = 0.01), systolic blood pressure (OR = 1.06, 95% CI: 1.02 - 1.10; p < 0.01) and male gender (OR = 3.24, 95% CI: 1.31 - 8.01; p = 0.01). Conclusions: OSA is independently associated with atrial and ventricular remodeling in patients with CD.


Resumo Fundamento: A doença de Chagas (DC) é uma causa importante de morbimortalidade por insuficiência cardíaca e arritmias malignas em todo o mundo, especialmente na América Latina. Objetivo: Investigar a associação entre apneia obstrutiva do sono (AOS) com remodelação cardíaca e arritmias cardíacas em pacientes com DC. Métodos: Foram incluídos pacientes consecutivos com DC, com idade entre 30 e 65 anos. Os participantes foram submetidos à avaliação clínica, estudo do sono, Holter de 24 horas, ecocardiograma e monitorização ambulatorial da pressão arterial. Resultados: Foram avaliados 135 pacientes [idade: 56 (45-62) anos; 30% homens; IMC: 26 ± 4 kg/m2, cardiomiopatia chagásica: 70%]. AOS moderada a grave (índice de apneia-hipopneia, IAH, ≥ 15 eventos/h) estava presente em 21% dos pacientes. AOS não estava associada a arritmias nessa população. Em comparação com pacientes com AOS leve ou ausente, pacientes com AOS moderada a grave apresentaram maior frequência de hipertensão (79% vs. 72% vs. 44%, p < 0,01) e pressão arterial sistólica noturna mais alta: 119 ± 17 vs. 113 ± 13 vs. 110 ± 11 mmHg, p = 0,01; diâmetro do átrio esquerdo maior [37 (33‑42) vs. 35 (33-39) vs. 33 (30-36) mm, p < 0,01]; e maior proporção de disfunção ventricular esquerda [FEVE < 50% (39% vs. 28% vs. 11%), p < 0,01], respectivamente. O preditor de dimensão do átrio esquerdo foi Log10 (IAH) (β = 3,86, IC 95%: 1,91 a 5,81; p < 0,01). Os preditores de disfunção ventricular foram IAH >15 eventos/h (OR = 3,61, IC 95%: 1,31 - 9,98; p = 0,01), pressão arterial sistólica (OR = 1,06, IC95%: 1,02 - 1,10; p < 0,01) e sexo masculino (OR = 3,24, IC 95%: 1,31 - 8,01; p = 0,01). Conclusões: A AOS está independentemente associada à remodelação atrial e ventricular em pacientes com DC.

RESUMO

OBJECTIVE: To evaluate the effect of noninvasive ventilation (NIV) on exercise performance in individuals with heart failure (HF). DESIGN: Crossover, blind, randomized controlled trial with allocation concealment. SETTING: University-based research laboratory. PARTICIPANTS: Participants (N=24) with New York Heart Association class II and III left heart failure and with a mean age of 51.8±10.2 years (women: n=8; men: n=16). INTERVENTIONS: Ventilatory support attached to the face of the individual via a facemask prior to cardiopulmonary exercise test (CPET) was administered at 2 pressure levels for 30 minutes. Inspiratory pressure of 15cmH2O and expiratory pressure of 5cmH2O were applied. MAIN OUTCOME MEASURES: Maximal oxygen uptake, maximum heart rate, variation between the initial and maximum heart rates, CPET duration, and recovery time oxygen consumption. RESULTS: Differences were observed in maximal oxygen consumption (nonintervention phase: 18.3±4.4mL·kg-1·min-1 vs NIV phase: 20.6±4.9mL·kg-1·min-1, P=.01), heart rate (nonintervention phase: 127.3±20.9 beats per minute vs NIV phase: 134.7±19.5 beats per minute, P=.04), and heart rate variation (nonintervention phase: 63.3%±19.3% vs NIV phase: 69.7%±16.6%, P=.02). Moreover, differences in cardiopulmonary exercise time (nonintervention phase: 7.4±1.5min vs NIV phase: 8.3±1.7min, P=.01) and oxygen consumption recovery time (nonintervention phase: 2.8±1.0min vs NIV phase: 2.4±0.8min, P=.01) were observed. CONCLUSIONS: NIV elicited beneficial effects in the HF population that included increased exercise tolerance, recovery time optimization, and improved chronotropic and respiratory reserves.

RESUMO

PURPOSE: Regulatory T cells are involved in the clinical course of chronic Chagas disease, possibly because they exercise a control in the patient's inflammatory response to Trypanosoma cruzi. This study analyzed the levels of CD4 + CD25+ T cells in chronic Chagas disease patients after in vitro stimulation of the peripheral blood mononuclear cells with CRA (Cytoplasmic Repetitive Antigen) or FRA (Flagellar Repetitive Antigen) T. cruzi antigens. METHODS: Groups of patients with the cardiac form and indeterminate form; and non-infected individuals, were selected. The CD4 + CD25+ T lymphocyte population, as well as the FoxP3 expression and the IL10 production, were evaluated by flow cytometry after stimulation with CRA or FRA. RESULT: The IND group presented higher levels of CD4 + CD25+ T cells than the CARD group. However, there was no evidence of a relationship between FoxP3 and IL10 with any of the chronic forms. CONCLUSIONS: Our results suggest the possible involvement of CD4 + CD25+ T cells specific to CRA and FRA in controlling the progression of clinical outcomes. Though, further studies are needed to define which mechanisms activate regulatory T cells and lead to pathology control in chronic human Chagas disease.

RESUMO

In the past two years we observed several changes in the diagnostic and therapeutic approach of patients with acute heart failure (acute HF), which led us to the need of performing a summary update of the II Brazilian Guidelines on Acute Heart Failure 2009. In the diagnostic evaluation, the diagnostic flowchart was simplified and the role of clinical assessment and echocardiography was enhanced. In the clinical-hemodynamic evaluation on admission, the hemodynamic echocardiography gained prominence as an aid to define this condition in patients with acute HF in the emergency room. In the prognostic evaluation, the role of biomarkers was better established and the criteria and prognostic value of the cardiorenal syndrome was better defined. The therapeutic approach flowcharts were revised, and are now simpler and more objective. Among the advances in drug therapy, the safety and importance of the maintenance or introduction of beta-blockers in the admission treatment are highlighted. Anticoagulation, according to new evidence, gained a wider range of indications. The presentation hemodynamic models of acute pulmonary edema were well established, with their different therapeutic approaches, as well as new levels of indication and evidence. In the surgical treatment of acute HF, CABG, the approach to mechanical lesions and heart transplantation were reviewed and updated. This update strengthens the II Brazilian Guidelines on Acute Heart Failure to keep it updated and refreshed. All clinical cardiologists who deal with patients with acute HF will find, in the guidelines and its summary, important tools to help them with the clinical practice for better diagnosis and treatment of their patients.

RESUMO

Were evaluated individuals divided into two groups: we studied chronic heart failure (CHF) (19 patients with CHF plus cardiomegaly) and control (12 healthy volunteers) during performance of inspiratory loaded breathing (ILB). We evaluated: spirometry, functional capacity through the six-minute walk test (6MWT), and distribution of thoracoabdominal volumes via optoelectronic plethysmography (OEP), namely volume variations of pulmonary rib cage (Vrc,p), abdominal rib cage (Vrc,a), and abdomen (Vab). In each compartment, the percentage contributions of right and left sides were also calculated. During ILB, patients with heart failure were characterized by a significant reduction of the Vrc,a volume variations compared to the control group. Correlations were found between left %Vrc,a on the left side measured during ILB and left ventricular ejection fraction (r=0.468; p=0.049), and dyspnea after the 6MWT (r=-0.878; p<0.01).Then, patients with CHF and cardiomegaly are characterized by a reduced mobility in left part of the lower part of the rib cage, that contributes leading to increased perception of dyspnea during submaximal exercise.

RESUMO

OBJETIVO: Identificar a prescrição e execução dos cuidados não farmacológicos nas prescrições médicas ou de enfermagem em três centros de referência no atendimento de pacientes com insuficiência cardíaca. MÉTODOS: Estudo de abordagem quantitativa, transversal de uma coorte multicêntrica. Incluíram-se pacientes admitidos por IC descompensada, classe funcional III/IV; de qualquer etiologia; idade ≥ 18 anos; de ambos os gêneros. RESULTADOS: Foram incluídos 562 pacientes, dentre os cuidados não farmacológicos, a restrição de sal foi o mais prescrito (95,4%), seguido pelo controle de diurese (48%). A proporção de cuidados prescritos e realizados foi maior no terceiro, e nos outros dois a diferença entre o prescrito e o realizado foi superior a 20%. CONCLUSÕES: Os cuidados não farmacológicos não estão totalmente incorporados à prática clínica. Estratégias que possam mobilizar a equipe multiprofissional com vistas às prescrições e realizações desses cuidados merecem ser estudadas.


OBJECTIVE: To identify the prescription and execution of non-pharmacological care in the medical or nursing prescriptions in three reference centers for the treatment of patients with heart failure. METHODS: A study using a quantitative, cross-sectional approach of a multicenter cohort. It included: patients admitted for decompensated heart failure, New York Heart Association function III / IV; any etiology; age of 18 years or older; and both genders. RESULTS: The study included 562 patients; among non-pharmacological care, salt restriction was the most prescribed (95.4%), followed by the control of diuresis (48%). The proportion of treatment prescribed and performed was higher in the third, and in the other two centers the difference between the prescribed and the performed was higher than 20%. CONCLUSIONS: Non-pharmacological care interventions are not fully incorporated into clinical practice. Strategies that can mobilize the multidisciplinary team with a view to the interventions and achievements of this care merit study.

RESULTADOS: Fueron incluídos 562 pacientes, de los cuidados no farmacológicos, la restricción de sal fue el más prescrito (95,4%), seguido por el control de diuresis (48%). La proporción de cuidados prescritos y realizados fue mayor en el tercero, y en los otros dos la diferencia entre el prescrito y el realizado fue superior a 20%. CONCLUSIONES: Los cuidados no farmacológicos no están totalmente incorporados a la práctica clínica. Merecen ser estudiadas estrategias que puedan mobilizar al equipo multiprofesional con miras a las prescripciones y realizaciones de esos cuidados.
