Abstract

Aims: While pulmonary embolism (PE) appears to be a major issue in COVID-19, data remain sparse. We aimed to describe the risk factors and baseline characteristics of patients with PE in a cohort of COVID-19 patients. Methods and results: In a retrospective multicentre observational study, we included consecutive patients hospitalized for COVID-19. Patients without computed tomography pulmonary angiography (CTPA)-proven PE diagnosis and those who were directly admitted to an intensive care unit (ICU) were excluded. Among 1240 patients (58.1% men, mean age 64 ± 17 years), 103 (8.3%) patients had PE confirmed by CTPA. The ICU transfer and mechanical ventilation were significantly higher in the PE group (for both P < 0.001). In an univariable analysis, traditional venous thrombo-embolic risk factors were not associated with PE (P > 0.05), while patients under therapeutic dose anticoagulation before hospitalization or prophylactic dose anticoagulation introduced during hospitalization had lower PE occurrence [odds ratio (OR) 0.40, 95% confidence interval (CI) 0.14-0.91, P = 0.04; and OR 0.11, 95% CI 0.06-0.18, P < 0.001, respectively]. In a multivariable analysis, the following variables, also statistically significant in univariable analysis, were associated with PE: male gender (OR 1.03, 95% CI 1.003-1.069, P = 0.04), anticoagulation with a prophylactic dose (OR 0.83, 95% CI 0.79-0.85, P < 0.001) or a therapeutic dose (OR 0.87, 95% CI 0.82-0.92, P < 0.001), C-reactive protein (OR 1.03, 95% CI 1.01-1.04, P = 0.001), and time from symptom onset to hospitalization (OR 1.02, 95% CI 1.006-1.038, P = 0.002). Conclusion: PE risk factors in the COVID-19 context do not include traditional thrombo-embolic risk factors but rather independent clinical and biological findings at admission, including a major contribution to inflammation.
