Plagiarism Of Hypertension Article In Korean Journal Results In Retraction

In response to evidence of plagiarism in a review article in the Korean Circulation Journal, the article has now been retracted by the journal. Here is the notice:

On July 31, 2011, Korean Circulation Journal (KCJ) published a review article by Park et al.1)regarding the J-curve in hypertension and coronary artery diseases. However, a possibility of plagiarism has been raised in this article.

The Editorial Board of KCJ has examined the review article and has requested the Committee for Publication Ethics of Korean Association of Medical Journal Editors (KAMJE) to provide an adequate conclusion. After thorough investigation, the Committee for Publication Ethics of KAMJE and the Editorial Board of KCJ have concluded that the article is seriously plagiarizing from an article by Messeri et al.2)

In this regard, on May 8, 2012, the Executive Committee of the Korean Society of Cardiology has finally decided to retract the article completely. We apologize for any inconvenience this may have caused.

By way of background, earlier this year I first reported that the KCJ article was suspiciously similar to a JACC article by Franz Messerli and Gurusher Panjrath. Shortly thereafter the editor-in-chief of the KCJ wrote me to say that an investigation into the matter had been initiated.

News of the retraction was first reported by Marilyn Mann. On the Retraction Watch blog, meanwhile, Ivan Oransky duly reported the retraction and then found another retraction in the same journalthis time for duplication of a case report of aortic dissection in an 11-year-old child.
