For the article “Growth Properties of Cardiac Stem Cells Are a Novel Biomarker of Patients’ Outcome After Coronary Bypass Surgery” (Circulation. 2014;129:157–172; DOI: 10.1161/CIRCULATIONAHA.113.006591) by Domenico D’Amario, Antonio M.

An expression of concern was published on November 20, 2018,¹ to alert readers that the American Heart Association was communicating with the authors and reviewing the materials provided by BWH. After considering input from authors, the American Heart Association has determined that the best interest of the public and the research community will be served by issuing this notice of retraction.

The American Heart Association, therefore, retracts the article.
