Journal retracts two papers by Japanese cardiologist under investigation

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.
