RESUMO
Objetivo: avaliar e comparar o conhecimento da doença entre os pacientes com Insuficiência Cardíaca (IC) em um hospital especializado em cardiologia. Método: trata-se de um estudo transversal. Foi aplicado um questionário de conhecimento da doença validado, além de dados sociodemográficos e um questionário de avaliação cognitiva. Os pacientes foram divididos em dois grupos, os do ambulatório de IC (GA) e os hospitalizados nas unidades de internação clínica (GI). Os pacientes que somaram entre 51-57 pontos (escore) tiveram classificação ótima de conhecimento. Resultados: a amostra foi de 98 pacientes, 49 no GA e 49 no GI, maioria do sexo masculino, idade média de 62 ± 14 anos. No GA, 51% apresentou nível aceitável de conhecimento e no GI, 55% apresentou pouco conhecimento. Conclusão: o conhecimento da IC entre pacientes ambulatoriais e internados foram diferentes e subótimos. Atividades de educação desenvolvidas pela equipe multiprofissional podem contribuir para melhor conhecimento da doença.
Objective: to evaluate and compare the knowledge of the disease among patients with heart failure (HF) in a hospital specialized in cardiology. Method: this is a cross-sectional study. A validated questionnaire about knowledge of disease was applied, as well as sociodemographic data and a cognitive assessment questionnaire. The patients were divided into two groups, those of the HF outpatient clinic (OC) and those hospitalized in the inpatient units (IU). Patients who scored between 51-57 points (score) had a great knowledge rating. Results: the sample was 98 patients, 49 in OC and 49 in IU, mostly male, mean age 62 ± 14 years. In OC, 51% had acceptable level of knowledge and in IU, 55% had poor knowledge. Conclusion: the knowledge of HF among outpatients and inpatients was different and suboptimal. Education activities developed by the multiprofessional team can contribute to better knowledge of the disease.

En CA, el 51% tenía un nivel de conocimiento aceptable y en UH, el 55% tenía poco conocimiento. Conclusión: el conocimiento de la IC entre pacientes ambulatorios y pacientes internos fue diferente y subóptimo. Las actividades educativas desarrolladas por el equipo multiprofesional pueden contribuir a un mejor conocimiento de la enfermedad.

OBJECTIVES: The aim of this study was to define the performance of lung ultrasound (LUS) compared with clinical assessment, natriuretic peptides, and echocardiography, to evaluate decompensation in patients with systolic heart failure (HF) in an outpatient clinic. BACKGROUND: Evaluation of pulmonary congestion in chronic HF is challenging. LUS has been recently proposed as a reliable tool for the semiquantification of extravascular lung water through assessment of B-lines. METHODS: This was a cohort study of patients with moderate to severe systolic HF. Receiver-operating characteristic (ROC) analyses were performed to compare LUS with a previously validated clinical congestion score (CCS), amino-terminal portion of B-type natriuretic peptide (NT-proBNP), E/e' ratio, chest x-ray, and 6-min walk test. RESULTS: Ninety-seven patients were enrolled. Decompensation was present in 57.7% of patients when estimated by CCS, 68% by LUS, 53.6% by NT-proBNP, and 65.3% by E/e' ≥15. The number of B-lines was correlated to NT-proBNP (r = 0.72; p < 0.0001), E/e' (r = 0.68; p < 0.0001), and CCS (r = 0.43; p < 0.0001). In ROC analyses, considering as reference for decompensation a combined method (E/e' ≥ 15 and/or NT-proBNP >1,000 pg/ml), LUS yielded a C-statistic of 0.89 (95% confidence interval: 0.82 to 0.96), providing the best accuracy with a cutoff ≥ 15 B-lines (sensitivity 85%, specificity 83%). A systematic approach using CCS, E/e', NT-proBNP, chest x-ray, and 6-min walk test in different combinations as reference for decompensation also corroborated this cutoff and found a similar accuracy for LUS. CONCLUSIONS: In an HF outpatient clinic, B-lines were significantly correlated with more established parameters of decompensation. A B-line ≥15 cutoff could be considered for a quick and reliable assessment of decompensation in outpatients with HF.
