the rest of the algorithm was followed. If a patient did not meet any of the three YEARS criteria and the d-dimer level was less than 1000 ng per milliliter or if a patient met one or more of the ...

Overall, the Wells rule, the revised Geneva score, and the YEARS algorithm were most efficient (based on the proportion of patients with PE ruled out without the use of imaging) when combined with ...

Based on the algorithm, PE was excluded and CPTA was withheld in 1,651 patients who either had: no YEARS items and a D-dimer level <1000 ng/mL; or one or more YEARS items and a D-dimer level <500 ...

For patients with suspected pulmonary embolism, diagnostic strategies to rule out PE that apply adapted D-dimer thresholds ... adapted D-dimer thresholds as well as the YEARS algorithm to rule ...

In the past several years, elevated factor VIII and D-dimer levels have emerged as risk ... 0.2 to 0.7 anti-Xa activity units per milliliter; for low-molecular-weight heparin, 0.5 to 1.0 anti ...

Editor's note: Find the latest COVID-19 news and guidance in Medscape's Coronavirus Resource Center. The plasma D-dimer assay has been used, along with clinical prediction scores, to rule out ...

2 Table 1 shows currently available D-dimer commercial tests, the results of which are expressed either as “fibrinogen equivalent unit” (FEU), or “D-dimer unit” (DDU, which is approximately half of ...

The ability of plasma D-dimer concentrations to correctly classify patients with PE was examined. Of the 287 patients with COVID-19 and suspected PE, 118 required intensive care unit levels of ...

In the new study, Dr. Parvizi and colleagues compared plasma D-dimer and other tests for the diagnosis of PJI. Over a four-year period, the study prospectively enrolled 502 patients undergoing ...
