Cover Story: In a retrospective study with a case–control design, we addressed two research questions. First, we assessed the specificity of an absolutely elevated D-dimer value to predict pulmonary embolisms in COVID-19 patients upon admission to an ICU. During the ICU stay, D-dimers were measured twice weekly. Our second research question investigated the specificity of a D-dimer increment in patients with no PE upon an initial CT pulmonary angiogram for the development of a PE during an ICU stay. The results showed that strongly elevated D-dimers upon admission (> 9000 μg/L), or a marked increase in D-dimers during the ICU stay (> 8000 μg/L), have strong predictive values for pulmonary embolisms in critically ill COVID-19 patients, and may aid clinicians in choosing an appropriate diagnostic follow-up.
