The study investigated the prevalence of pulmonary embolism (PE) in patients with COVID-19 pneumonia, finding an 18.4% prevalence among 239 patients.
Common symptoms included dyspnea (58.6%), cough (56.1%), and chest pain (40.2%), and many patients underwent chest CT angiography without prior D-dimer testing.
The research concluded that elevated D-dimer levels significantly correlate with the incidence of pulmonary embolism, indicating the importance of using both CT angiography and D-dimer levels for diagnosis.
