correction to: risk stratification with vasodilator stress spect myocardial perfusion imaging in patients with elevated cardiac biomarkers

The following error (highlighted in bold below) appears in the results section of the abstract: a total of 503 patients were followed for an average of 33.6 ± 16.2 months, with a mean age of 69.3 years; 53.7% male; and a majority (88.7%) of them undergoing vasodilator stress. a significant increase in all-cause mortality was seen based on the severity of tpd results for all vasodilators (p < .0001) and regadenoson (p < .0001). similar prognostic ability was seen for all-cause (this should actually be cardiac) mortality. this association was maintained even after adjustment for cardiac risk factors, previous coronary disease, and troponin quartiles. mpi results (stress tpd and lvef) added to traditional cardiac risk factors, and troponin values resulted in a significant incremental increase in the ability to predict all-cause and cardiac mortality, and stress tpd remained independently predictive for both all-cause and cardiac mortality in a multivariate model.
