After three retractions, five expressions of concern, cardiologist Matsubara resigns post

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.

Mainichi Shimbun reports — according to our roughest of (Google) translations — that Kyoto Prefectural University accepted Matsubara’s resignation following an investigation. That investigation — which the university had told us about last year — revealed serious problems with 27 studies.

As we noted last March:

Matsubara is a big name in cardiology, having been part of the KYOTO HEART study and other clinical trials. Twenty one of his papers have been cited at least 100 times, with one cited more than 800.

One of Matsubara’s retractions was for duplication, but the other notices made vague noises about data problems.
