with 3 comments

matsubaraHiroaki Matsubara, a leading Japanese cardiology researcher who has had three papers retracted and another five subject to expressions of concern, has resigned from Kyoto Prefectural University, according to local media.

Journal retracts two papers by Japanese cardiologist under investigation

without comments

matsubaraThe Circulation Journal, the official organ of the Japanese Circulation Society, is retracting two papers by Hiroaki Matsubara, lead researcher on the Kyoto Heart Study, for unreliable findings. Matsubara’s institution, Kyoto Prefectural University, confirmed to us last March that it was investigating the prominent cardiologist.

The work of Matsubara came into question last year when the American Heart Association issued an expression of concern for five papers the society published in its journals. Larry Husten, at Forbes/CardioBrief, reports today that the two retracted articles were “Effects of Valsartan on Cardiovascular Morbidity and Mortality in High-Risk Hypertensive Patients With New-Onset Diabetes Mellitus: Sub-Analysis of the KYOTO HEART Study,” published in September 2012; and “Enhanced cardiovascular protective effects of valsartan in high-risk hypertensive patients with left ventricular hypertrophy: Sub-analysis of the KYOTO HEART study,” which appeared in March 2011.

The American Heart Association, which publishes a number of journals, has issued an Expression of Concern about five papers in three of their publications, following allegations of image manipulation. All of the papers include Hiroaki Matsubara, of Kyoto Prefectural University, as a co-author.

The notice begins:

It has come to the attention of the American Heart Association (AHA), in a public manner, that there are questions concerning a number of figures in several AHA journals’ articles…

The “public manner” was three posts last year on the Abnormal Science blog, available here, here and here, alleging that images were manipulated in the manuscripts, and that histology slides were reused.
