In the version of the article, “Acute Myocardial Infarction and Congestive Heart Failure Outcomes at Specialty Cardiac hospitals,” by Nallamothu et al that was posted online on October 29, 2007 (DOI: 10.1161/CIRCULATIONAHA.107.709220), several errors occurred.
In Table 1, the mean number of AMI patients at Cardiac Hospitals should have been 120, not 1120. In the same table, the mean number of annual coronary artery bypass grafting cases at peer General Hospitals should have read 82 rather than 83.
In Table 2, P for peripheral vascular disease should have been listed as 0.01 rather than 0.0131.
These errors have been corrected in the final print version of the article in the November 13, 2007, issue of the journal (Circulation. 2007;116:2280–2287) and in the current online version. The publisher regrets these errors.
