In the 230 patients that were risk stratified to have imaging, 135 (58.7%) had a positive d-dimer assay only, 3 (1.3%) had a high pretest clinical probability of pulmonary embolism only, and 92 (40.0%) had both. Of the 229 that underwent imaging, 97 were diagnosed with PE.
Of the 97 patients ultimately diagnosed with PE, do you know the breakdown of what % had positive d-dimer only, high clinical probability only, or both? For example, were the majority of the 97 PEs seen in patients with both positive d-dimer and high clinical probability, or with positive d-dimer only?
