In the article, “Effect of Sulfaphenazole on Tissue Plasminogen Activator Release in Normotensive Subjects and Hypertensive Patients,” by Giannarelli et al, which appeared in the March 31, 2009, issue of the journal (Circulation. 2009;119:1625–1633), an error occurred.
Table 2 of the article reports the arterial, venous and arteriovenous concentration gradient of tissue-type plasminogen activator (t-PA) at baseline and after infusion of bradykinin and sodium nitroprusside. The above-mentioned concentrations of t-PA should be ng/mL instead of ng · min−1 · 100 mL−1 as inappropriately reported in the Table. This was a typographical error, and the calculation of t-PA release had been properly performed as reported in the Methods section. The Table, reproduced below, has been corrected in the current online version of the article.
The authors regret the error.
