“…Still referring to the SF-36 instrument, an intervention work was carried out in which QoL was assessed at baseline and after two different interventions, with one group undergoing ventricular stimulation and another atrioventricular stimulation. The domains of Functional Capacity and Vitality showed an increase in QoL scores, however for the General State domain, there was a reduction in scores after intervention; at baseline the mean reduced from 73.9 to 68.1 in the ventricular stimulation and to 69.4 in the atrioventicular 38 ( Table 3 ).…”

Chagas disease (CD) is a neglected tropical highly morbid disease that can have a negative impact on the quality of life (QoL). The purpose of this study was to conduct an integrative review to analyze the QoL of patients with CD in the chronic phase of the disease, as well as the instruments used and the effect of different interventions. The review was carried out based on the criteria and recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes guideline (PRISMA) using the PubMed, Scopus, Web of Science and Science Direct databases. An analysis of the reference list of the included articles was also carried out. Publications in all languages have been included. Two independent reviewers selected the eligible articles and extracted the data. A total of 1,479 articles were identified, and after applying the inclusion criteria 18 articles were included. Four different instruments were used to assess QoL and the most used was the Minnesota Living with Heart Failure Questionnaire (MLWHFQ) [33.3% (n = 6)]. Investigations involving intervention showed a positive impact on the patients’ QoL, and the Environment domain had the lowest score. Heterogeneity of instruments and lack of methodology standardization for assessing QoL was observed. QoL proved to be an important indicator for the planning and monitoring of patients with CD, however it is suggested that the instruments for its assessment should be the ones recommended by the validation studies. This process will allow the comparison of data between investigations.

“…Sá et al18 found that, after eight months of pacemaker implantation, there was worsening of the results obtained in the 6MWT in relation to the first month after the implant. Therefore, although the 6MWT is considered a submaximal test that triggers global and integrated responses of the systems involved during exercise, it is not able to show differences related to ventricular or AV pacing modes15 .…”

Introduction: Atrioventricular stimulation provides hemodynamic benefits over the isolated ventricular rate, but this advantage is not completely established in chagasic patients with systolic dysfunction. Objectives: To evaluate the influence of DDD and VVIR stimulation modes on functional capacity, quality of life (QoL) and laboratory abnormalities of a natriuretic peptide in chagasic patients with ventricular dysfunction submitted to pacemaker implantation. Methods: Twenty patients (55% male) with a mean age of 62.7 (± 9.9 years) and a mean ejection fraction of 41.8% (± 2.8) were prospectively studied. Alternately, patients received pacing in the DDD and VVIR modes for a period of three months under each schedule. The minimum percentage of ventricular pacing was 80%. After each period, the patient was submitted to the six-minute walk test (6MWT), QOL assessment by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and the Assay of QUAlity of life and RELated events (AQUAREL). Laboratory evaluation was performed with the N-terminal fraction of the brain natriuretic peptide (N-terminal pro b-type natriuretic peptide - NT-proBNP). Results: The mean distance walked on the 6MWT in the DDD and VVIR modes were 390.60 (± 52.71) and 396.30 (± 52.71) meters respectively (p = 0.160). Results of lower QOL were found, considering the physical domain of the MLHFQ (p = 0.03) and the domains of effort dyspnea (p = 0.05) and arrhythmia (p <0.001) of the AQUAREL with the VVIR mode. NT-proBNP levels increased significantly with stimulation in VVIR mode (p < 0.001). Conclusion: After three months of stimulation with the VVIR mode, there was worsening of the QoL of the chagasic patients and increase of the levels of NT-proBNP (clinical trial record: ReBEc RBR-53x476).

Methodological adequacy of articles published in two open-access Brazilian cardiology periodicals

2010

CONTEXT AND OBJECTIVE: The use of rigorous scientific methods has contributed towards developing scientific articles of excellent methodological quality.This has made it possible to promote their citation and increase the impact factor. Brazilian periodicals have had to adapt to certain quality standards demanded by these indexing organizations, such as the content and the number of original articles published in each issue. This study aimed to evaluate the methodological adequacy of two Brazilian periodicals within the field of cardiology that are indexed in several databases and freely accessible through the Scientific Electronic Library Online (SciELO), and which are now indexed by the Web of Science (Institute for Scientific Information, ISI). DESIGN AND SETTING:Descriptive study at Brazilian Cochrane Center. METHODS:All the published articles were evaluated according to merit assessment (content) and form assessment (performance).RESULTS: Ninety-six percent of the articles analyzed presented study designs that were adequate for answering the objectives.CONCLUSIONS: These two Brazilian periodicals within the field of cardiology published methodologically adequate articles, since they followed the quality standards. Thus, these periodicals can be considered both for consultation and as vehicles for publishing future articles. For further analyses, it is essential to apply other indicators of scientific activity such as bibliometrics, which evaluates quantitative aspects of the production, dissemination and use of information, and scientometrics, which is also concerned with the development of science policies, within which it is often superimposed on bibliometrics.RESUMO CONTEXTO E OBJETIVO: A utilização de métodos científicos rigorosos tem contribuído para o desenvolvimento de artigos científicos de excelente qualidade metodológica, o que permite a promoção da sua citação, bem como o aumento do fator de impacto. Os periódicos nacionais tiveram que se adequar a alguns padrões de qualidade exigidos pelos indexadores, como por exemplo o conteúdo e o número de artigos originais publicados em cada fascículo. O objetivo foi avaliar a adequação metodológica de dois periódicos brasileiros, na área de cardiologia, indexados em várias bases de dados e disponíveis em livre acesso na Scientific Electronic Library Online (SciELO) e atualmente indexados na Web of Science (Institute for Scientific Information, ISI). TIPO DE ESTUDO E LOCAL: Estudo descritivo realizado no Centro Cochrane do Brasil.MÉTODO: Todos os artigos foram avaliados quanto ao mérito (conteúdo) e quanto à forma (desempenho).RESULTADO: Foi observada uma taxa de 96% de adequação metodológica entre os artigos avaliados, que apresentaram desenho de estudo adequado para responder o objetivo proposto.CONCLUSÕES: Esses dois periódicos brasileiros na área da cardiologia publicaram artigos metodologicamente adequados, considerando os critérios de qualidade utilizados. Assim, esses periódicos podem ser considerados para consulta e como veículos para a publ...
