May aid AAD exclusion in suspected cases; leaves open need for prospective validation before practice change.
Does a rapid bedside D-dimer assay accurately detect or exclude acute aortic dissection in patients with suspected AAD?
A rapid bedside D-dimer assay provides 100% sensitivity and negative predictive value, making it a highly effective tool for the early exclusion of acute aortic dissection in patients with suggestive chest or back pain.
