    <p>With the recent disclosure of the journals impact factors of 2014 by Thomson-Reuters, we verified that the Brazilian Archives of Cardiology maintained its Impact Factor (IF) at the same levels observed in recent years, contrary to the expected prospects since the publication of its first index five years ago<xref ref-type="bibr" rid="B01">1</xref>. A similar situation has also been observed regarding most journals with international scope published in Brazil, despite the many efforts by their editors to attract the publication of the best scientific quality articles, as well as to improve publication editorial quality.</p>
    <p>The fact that the IF has remained unchanged represents a significant problem for the national publication journals, as the Brazilian postgraduate courses are the most important suppliers of high-quality works for publication and the main mission of our journals is precisely to facilitate the dissemination of scientific research carried out in our country. As the result of the maintenance of the scoring criteria of postgraduate programs by the Higher Education Personnel Training Coordination (Coordena&#231;&#227;o de Aperfei&#231;oamento de Pessoal de N&#237;vel Superior - Capes) of the Ministry of Education, based on the impact factor of journals where our scientists publish their research, a vicious circle is formed, which does not favor the development of our publications.</p>
    <p>In a previous editorial, we demonstrated that the publication of articles with better scientific quality by Brazilian authors in the field of Cardiology and Cardiovascular Science occurs primarily in journals published in other countries, a situation justified by the higher impact factor of these journals<xref ref-type="bibr" rid="B02">2</xref>.</p>
    <p>On the other hand, we are currently witnessing the expansion of the scientific research broadcasting in the media through portals of indexers that often bring us access to scientific information even before the official publication in printed form, as well as the easy access to complete articles through electronic libraries. These facts favor the citation of scientific articles primarily based on their scientific and editorial quality or even the credibility of the involved research groups, a situation that makes us consider whether the scientific impact of the work is actually related to the impact factor of the journals where they are published.</p>
    <p>Aiming to assess the scientific relevance of articles published by Brazilian authors in journals with international scope published in Brazil and abroad in the field of cardiology, we researched publications of original or review articles carried out over the past five years on the following indexers: "myocardial revascularization", "atrial fibrillation" and "Chagas cardiomyopathy".</p>
    <p>Only citations obtained by studies carried out exclusively by Brazilian authors in the "Web of Science" database of Thomson-Reuters were analyzed, as multicenter studies with the participation of national centers are predominantly published in higher-impact factor journals and tend to have a greater impact due to their scope. The identified studies were the ones that received at least one citation during that period and we compared the H indices obtained by articles published in Brazilian journals with those obtained by articles published in international journals, as publication in international journals is usually justified by the higher impact factors of the latter when compared to national ones.</p>
    <p>When analyzing the indexer "myocardial revascularization", 207 publications were identified, which received 825 citations in the period, with an H index of 12. Among the 156 studies published in Brazilian journals, 94 (60%) were cited by other publications in the period, with an H index of 10. A similar situation was observed regarding 50 studies by Brazilian authors published in foreign journals, emphasizing the fact that only 29 of these articles (57%) received citations in the period, with an H index of 8. When analyzing the indexer "atrial fibrillation", 177 publications were identified, which received 507 citations in the period, with an H index of 10. The evaluation of the 97 articles published in Brazilian journals showed that 48 (47%) received at least one citation whereas, of the 70 articles published in international journals, 51 (73%) received citations in the literature. In spite of the higher rate of cited articles in international journals, H index values were similar for articles published in Brazilian journals and those published in other countries (8 and 9, respectively).</p>
    <p>On the other hand, when evaluating the indexer "Chagas cardiomyopathy", we observed a predominance of publications by Brazilians authors in foreign journals (139), in comparison to only 55 articles published in national publications. The articles published in foreign journals totaled more than 1,500 citations obtained by 113 articles (81%) in the last five years, with an H-index of 17, while only 37 (67%) of the 55 articles published in Brazil received 161 citations, with an H index 6.</p>
    <p>The data shown here demonstrate there was no difference regarding citation indexes obtained by articles published in either Brazilian journals or international ones, in a broad area of topics in the field of cardiovascular sciences. However, this situation is not the same with articles that address specific topics such as Chagas cardiomyopathy, of which interest by international publications of greater impact for the contribution of Brazilian science justifies the higher acceptance rate and citations of these articles.</p>
    <p>Unquestionably, Brazilian science should be widely disseminated by several international indexers and by the best journals in each field of knowledge in a balanced manner, especially focusing on the mission and the specific audience of each publication when choosing the vehicle of disclosure<xref ref-type="bibr" rid="B03">3</xref>.</p>
    <p>However, one can conclude, based on the aspects mentioned in this Editorial, that the higher impact factor of foreign journals is not a valid justification for choosing them as a better vehicle of disclosure for Brazilian cardiology science. This situation demonstrates the need to review the evaluation criteria of national scientific production, primarily based on citation indexes obtained by the articles themselves, to stop focusing on the impact factor of foreign journals at the expense of journals published in our own country.</p>

      <p>Com a recente divulga&#231;&#227;o dos fatores de impacto dos peri&#243;dicos de 2014 pela   <italic>Thomson-Reuters</italic>, constatamos a manuten&#231;&#227;o do Fator de Impacto dos   <italic>Arquivos Brasileiros de Cardiologia</italic> nos mesmos n&#237;veis observados nos &#250;ltimos anos, contrariando as expectativas apontadas a partir da publica&#231;&#227;o de seu primeiro &#237;ndice h&#225; cinco anos<xref ref-type="bibr" rid="B01">1</xref>. Situa&#231;&#227;o semelhante tamb&#233;m p&#244;de ser observada com rela&#231;&#227;o &#224; maioria dos peri&#243;dicos de divulga&#231;&#227;o internacional publicados no Brasil, apesar dos in&#250;meros esfor&#231;os de seus editores no sentido de tentar atrair a publica&#231;&#227;o de artigos de melhor qualidade cient&#237;fica, bem como de melhorar a qualidade editorial das publica&#231;&#245;es.</p>
      <p>A manuten&#231;&#227;o desta circunst&#226;ncia representa um problema importante para os peri&#243;dicos de publica&#231;&#227;o nacional, uma vez que temos na P&#243;s-Gradua&#231;&#227;o brasileira os maiores fornecedores de trabalhos de melhor qualidade para publica&#231;&#227;o, sendo a principal miss&#227;o de nossos peri&#243;dicos justamente facilitar a divulga&#231;&#227;o da pesquisa cient&#237;fica realizada em nosso pa&#237;s. Com a manuten&#231;&#227;o dos crit&#233;rios de pontua&#231;&#227;o dos Programas de P&#243;s-Gradua&#231;&#227;o pela Coordena&#231;&#227;o de Aperfei&#231;oamento de Pessoal de N&#237;vel Superior (CAPES) do Minist&#233;rio da Educa&#231;&#227;o, com base no fator de impacto dos peri&#243;dicos nos quais nossos cientistas publicam suas pesquisas, forma-se um c&#237;rculo vicioso que n&#227;o favorece o crescimento de nossas publica&#231;&#245;es. Em editorial anterior, documentamos que a publica&#231;&#227;o dos artigos de melhor qualidade cient&#237;fica de autores brasileiros no campo da cardiologia e das ci&#234;ncias cardiovasculares ocorre predominantemente em peri&#243;dicos publicados em outros pa&#237;ses, situa&#231;&#227;o justificada pelo maior fator de impacto destes peri&#243;dicos<xref ref-type="bibr" rid="B02">2</xref>.</p>
      <p>Por outro lado, presenciamos atualmente a amplia&#231;&#227;o dos meios de divulga&#231;&#227;o da pesquisa cient&#237;fica por meio de indexadores que nos trazem, muitas vezes, o acesso &#224; informa&#231;&#227;o cient&#237;fica antes mesmo da publica&#231;&#227;o oficial dos trabalhos em forma impressa, bem como a facilidade da r&#225;pida obten&#231;&#227;o dos artigos completos por meio das bibliotecas eletr&#244;nicas. Estes fatos favorecem a cita&#231;&#227;o dos artigos cient&#237;ficos principalmente com base em sua qualidade cient&#237;fica e editorial ou mesmo na credibilidade dos grupos de pesquisa envolvidos, situa&#231;&#227;o que nos leva a refletir se o impacto cient&#237;fico dos trabalhos est&#225; realmente relacionado ao fator de impacto dos peri&#243;dicos nos quais eles est&#227;o publicados.</p>
      <p>Com o objetivo de avaliar a relev&#226;ncia cient&#237;fica dos artigos publicados por autores brasileiros em peri&#243;dicos de circula&#231;&#227;o internacional publicados no Brasil e no exterior no campo da cardiologia, pesquisamos as publica&#231;&#245;es de artigos originais ou de revis&#227;o realizadas nos &#250;ltimos cinco anos a respeito dos seguintes indexadores: "<italic>myocardial revascularization</italic>","<italic>atrial fibrillation</italic>" e "<italic>Chagas cardiomyopathy</italic>". Foram analisadas as cita&#231;&#245;es obtidas pelos trabalhos realizados exclusivamente por autores brasileiros na base de dados "<italic>Web of Science</italic>" da <italic>Thomson-Reuters</italic>, uma vez que os trabalhos multic&#234;ntricos com a participa&#231;&#227;o de centros nacionais s&#227;o publicados predominantemente em peri&#243;dicos de impacto mais elevado e tendem a ter uma repercuss&#227;o maior por causa de sua abrang&#234;ncia. Foram identificados os trabalhos que receberam pelo menos uma cita&#231;&#227;o no per&#237;odo, sendo comparados os &#237;ndices H obtidos pelos artigos publicados em peri&#243;dicos brasileiros com os obtidos por artigos publicados no estrangeiro, uma vez que o encaminhamento das publica&#231;&#245;es para peri&#243;dicos estrangeiros &#233; normalmente justificada pela exist&#234;ncia de fatores de impacto mais elevados nestes peri&#243;dicos do que nos nacionais.</p>
      <p>Ao analisarmos o indexador "<italic>myocardial revascularization</italic>", foram identificadas 207 publica&#231;&#245;es que receberam 825 cita&#231;&#245;es no per&#237;odo, com um &#237;ndice H de 12. Entre os 156 trabalhos publicados em peri&#243;dicos brasileiros, 94 (60%) foram citados por outras publica&#231;&#245;es no per&#237;odo, sendo observado um &#237;ndice H de 10. Situa&#231;&#227;o semelhante foi observada com rela&#231;&#227;o aos 50 trabalhos publicados por autores brasileiros em peri&#243;dicos estrangeiros, ressaltando-se que apenas 29 desses artigos (57%) receberam cita&#231;&#245;es no per&#237;odo, com um &#237;ndice H de 8. Quando analisamos o indexador "<italic>atrial fibrillation</italic>", identificamos 177 publica&#231;&#245;es que receberam 507 cita&#231;&#245;es no per&#237;odo, com um &#237;ndice H de 10. A avalia&#231;&#227;o dos 97 artigos publicados em peri&#243;dicos com sede no Brasil mostrou que 48 (47%) receberam pelo menos uma cita&#231;&#227;o, enquanto que, entre os 70 artigos publicados em peri&#243;dicos estrangeiros, 51 (73%) receberam cita&#231;&#245;es na literatura. Apesar do maior &#237;ndice de artigos citados nos peri&#243;dicos estrangeiros, os valores dos &#237;ndices H foram semelhantes para artigos publicados em peri&#243;dicos brasileiros ou publicados em outros pa&#237;ses (8 e 9, respectivamente).</p>
      <p>Por outro lado, quando avaliamos o indexador "<italic>Chagas cardiomyopathy</italic>", foi observado o predom&#237;nio de publica&#231;&#245;es realizadas por brasileiros em peri&#243;dicos estrangeiros (139) contra apenas 55 artigos divulgados em publica&#231;&#245;es nacionais. Os artigos publicados em peri&#243;dicos estrangeiros somaram mais de 1500 cita&#231;&#245;es obtidas por 113 artigos (81%) nos &#250;ltimos cinco anos, com um &#237;ndice H de 17, enquanto que apenas 37 (67%) dos 55 artigos publicados no Brasil receberam 161 cita&#231;&#245;es, com um &#237;ndice H de 6.</p>
      <p>Os dados apresentados demonstram que n&#227;o houve diferen&#231;a com rela&#231;&#227;o aos &#237;ndices de cita&#231;&#227;o obtidos por artigos publicados em peri&#243;dicos com sede no Brasil ou em pa&#237;ses estrangeiros em temas de amplo dom&#237;nio no campo das ci&#234;ncias cardiovasculares. No entanto, esta situa&#231;&#227;o n&#227;o ocorre com artigos que abordam temas espec&#237;ficos como a cardiomiopatia chag&#225;sica, cujo interesse das publica&#231;&#245;es internacionais de maior impacto pela contribui&#231;&#227;o da ci&#234;ncia brasileira justifica os maiores &#237;ndices de aceita&#231;&#227;o e de cita&#231;&#227;o destes artigos.</p>
      <p>Sem d&#250;vida, devemos ter a ci&#234;ncia brasileira amplamente veiculada pelos diversos indexadores internacionais e pelos melhores peri&#243;dicos de cada &#225;rea do conhecimento de forma equilibrada, privilegiando principalmente a miss&#227;o e o p&#250;blico espec&#237;fico de cada publica&#231;&#227;o na escolha do ve&#237;culo de divulga&#231;&#227;o<xref ref-type="bibr" rid="B03">3</xref>. No entanto, podemos concluir, com base nos aspectos mencionados neste Editorial, que o maior fator de impacto dos peri&#243;dicos estrangeiros n&#227;o &#233; uma justificativa v&#225;lida para a sua escolha como um melhor ve&#237;culo de divulga&#231;&#227;o da ci&#234;ncia cardiol&#243;gica brasileira. Esta situa&#231;&#227;o demonstra a necess&#225;ria revis&#227;o dos crit&#233;rios de avalia&#231;&#227;o da produ&#231;&#227;o cient&#237;fica nacional com base principalmente nos &#237;ndices de cita&#231;&#227;o obtidos pelos pr&#243;prios artigos, deixando de privilegiar o fator de impacto dos peri&#243;dicos estrangeiros em detrimento dos peri&#243;dicos publicados em nosso pa&#237;s.</p>
