In the Editorial by Gu et al, “The Emerging Role of Thrombus Aspiration in the Management of Acute Myocardial Infarction,” which appeared in the October 28, 2008, issue of the journal (Circulation. 2008;118:1780–1782), many of the numbers cited do not match those used in the final version of the article being discussed.
On page 1781, first full paragraph, line 7, the Pvalue should read “P<0.001” rather than “P<0.00001.”
On line 8, “19 versus 12%” should be replaced by “18 versus 12%.”
Starting on line 12, the text beginning, “During a median follow-up of 2.5 years . . . .” should be replaced by the following through to the end of the paragraph:
“At 4 years follow-up, all-cause mortality was 2-fold higher in patients with older thrombus compared with patients with fresh thrombus (16.0% versus 7.4%, hazard ratio 1.82, 95% confidence interval 1.17 to 2.85, P=0.008). In a landmark survival analysis, this higher mortality rate of patients with older thrombus versus those with fresh thrombus was apparent during the first 14 days (5.7% versus 2.4%; P=0.009) but not after 14 days (11% versus 5.2%, P=0.20). In multivariate Cox regression analysis, the presence of older thrombus was an independent predictor of all-cause mortality at 4 years (hazard ratio 1.83, 95% confidence interval 1.14 to 2.93, P=0.01) next to well known risk factors such as female gender, age >60 years, diabetes mellitus, previous coronary artery bypass grafting, cardiogenic shock, and poor postprocedural TIMI flow.”
These changes have been made to the current online version of the article. The publisher regrets the errors.
