Abstract
Announcement of Retraction
The editorial office of International Heart Journal has recently confirmed that the clinical study written by Masataka Yoda, et al published in the March 2008 issue of International Heart Journal (Int Heart J 2008; 49: 213-220), was a duplicate publication, which violates the prepublication agreement that any submission to IHJ should be the first publication on an ex-clusive basis. Therefore, we hereby notify our readers that the paper has been retracted.
