Objective: The aim: A comparative analysis of the course of pulmonary embolism during the COVID-19 pandemic and the era before pandemia.
Patients and methods: Materials and methods: 294 patients with pulmonary embolism (PE) , 1 group - 188 with PE before the pandemic, 2 group -106 during the pandemic. Two subgroups were distinguished in 2 group : 1- with laboratory-excluded coronavirus (acute and in anamnesis) and 2 - with a history of COVID-19. The diagnosis of PE was confirmed by CT. Echocardiography and ultrasound Doppler imaging of the veins of the lower extremities were performed.
Results: Results: In 1 group there was a more significant increase in pulmonary artery pressure (44.29 ± 17.04 vs 36.91 ± 16.6, p 0.0023) and a decrease in the E/A ratio of the right ventricle (0.80 ± 0,21 vs 1.28 ± 1.42, p 0.0202). In 2 subgroup of patients with COVID-19 had a significantly higher incidence of Diabetes mellitus (73.7% vs 13.3%, p 0.00001) and significantly lower signs of superficial venous thrombosis of the lower extremities (5.3% vs 33,3%, p 0,0175) and signs of proximal deep vein thrombosis (0% vs 56.7%, p 0.00001) and 3 times less often there was a high risk of adverse disease, right ventricular dysfunction were more pronounced (ratio E/A 0.87 ± 0.25 vs 1.13 ± 0.28, p 0.022).
Conclusion: Conclusions: In patients with coronavirus infection, PE was significantly more common in the presence of diabetes mellitus , right ventricular diastole disorders were more common, and superficial and proximal deep vein thrombosis of the lower extremities were less common.
