Urgent Announcement From the Editor-in-Chief
Concerning Article Retraction

December 27, 2012

The editorial team of Circulation Journal has recently confirmed that the manuscript written by Jun Shiraishi et al, published in the April 2011 issue of the Circulation Journal (Circ J. 2011;75:806-814), contains a number of serious errors in data analysis.

Jun Shiraishi, Takahisa Sawada, Shinzo Kimura, Hiroyuki Yamada, Hiroaki Matsubara ; KYOTO HEART Study Group. Enhanced cardiovascular protective effects of valsartan in high-risk hypertensive patients with left ventricular hypertrophy--sub-analysis of the KYOTO HEART study. Circ J. 2011;75:806-814.

Therefore, we have decided to retract the paper from Circulation Journal.

As Editor-in-Chief, I regret the time that peer reviewers and others spent evaluating this paper. I sincerely hope and trust that there will be no repetition of this kind in the future.
