In the Circulation Research article by Nagendran et al (Endothelin axis is upregulated in human and rat right ventricular hypertrophy. Circ Res. 2013;112:347–354. DOI: 10.1161/CIRCRESAHA.111.300448), the text incorrectly referred to a Food and Drug Administration “black box warning” for ambrisentan; the text should have simply listed it as a “warning”.
The error has been corrected in the online version of the article, which is available at http://circres.ahajournals.org/content/112/2/347.
