CLINICS 2010;65(4):441-5 REVIEW A REVIEW OF CARDIOPULMONARY RESEARCH IN BRAZILIAN MEDICAL JOURNALS: CLINICAL, SURGICAL AND EPIDEMIOLOGICAL DATA Carlos Serrano, Mauricio Rocha e Silva doi: 10.1590/S1807-59322010000400014 Serrano C, Rocha-e-Silva M. A review of cardiopulmonary research in brazilian medical journals: clinical, surgical and epidemiological data. Clinics. 2010;65(4):441-5. Research in the field of cardiopulmonary disease in Brazil has been very active in recent decades. The combination of PUBMED, SCieLO, open access and online searching has provided a significant increase in the visibility of Brazilian journals. This newly ac- quired international visibility has in turn resulted in the appearance of more original research reports in the Brazilian scientific press. This review is intended to highlight part of this work for the benefit of the readers of “Clinics.” We searched through PUBMED for noteworthy articles published in Brazilian medical journals included in the Journal of Citation Reports of the Institute of Scientific Information to better expose them to our readership. The following journals were examined: “Arquivos Brasileiros de Cardiologia,” “Arquivos Brasileiros de Endocrinologia e Metabologia,” “Brazilian Journal of Medical and Biological Reviews,” “Jornal Brasileiro de Pneumologia,” “Jornal de Pediatria,” “Revista Brasileira de Cirurgia Cardiovascular,” “Revista da Associação Médica Brasileira,” Revista da Escola de Enfermagem U.S.P.” and “São Paulo Medical Journal.” These journals publish original investigations in the field of cardiopulmonary disease. The search produced 71 references, which are briefly examined. KEYWORDS: Cardiology; Pneumology; Clinical research; Surgery; Epidemiology. INTRODUCTION METHODS Research in the field of cardiopulmonary disease in Brazil has been very dynamic over recent decades. The combination of PUBMED, SCieLO, open access and internet searching has led to an increase in the visibility of Brazilian scientific journals. This in turn has produced a significant proportion of original research reports into the Brazilian scientific press with this newly acquired international visibility. This review is intended to highlight some of these studies for the benefit of the readers of CLINICS. We have therefore searched through PUBMED for significant articles in the field of cardiopulmonary disease published in Brazilian journals and included in the Journal of Citation Reports of the Institute of Scientific Information to better expose them to our readers.

The following journals were examined: “Arquivos Brasileiros de Cardiologia,” “Arquivos Brasileiros de Endocrinologia e Metabologia,” “Brazilian Journal of Medical and Biological Reviews,” “Jornal Brasileiro de Pneumologia,” “Jornal de Pediatria,” “Revista Brasileira de Cirurgia Cardiovascular,” “Revista da Associação Médica Brasileira,” Revista da Escola de Enfermagem U.S.P.” and “São Paulo Medical Journal.” Most of the articles reviewed were published in 2009. This search produced a total of 71 articles, which were divided into four categories: clinical cardiology, cardiac surgery, pneumology and epidemiology. The articles are summarized under these headings. Clinical cardiology. The importance of exercise for cardiac function was addressed by investigators who reported on the safety of the six-minute walk-test for heart Copyright © 2010 CLINICS – This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons. org/licenses/by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
