In the article by Lam et al, “Cardiac Structure and Ventricular–Vascular Function in Persons With Heart Failure and Preserved Ejection Fraction From Olmsted County, Minnesota,” which appeared in the April 17, 2007, issue of the journal (Circulation. 2007;115:1982–1990), the following corrections should be made.
On page 1982, the ß symbol in the equation should be superscripted so that the equation would read, “EDP=αEDVß.” This change should also be made to the same equation in the legend to Figure 3 on page 1987.
These errors have been corrected in the current online version of the article. The publisher regrets these errors.
