| Abstract | Background: Infection caused by SARS-CoV-2 can lead to significant procoagulant events, sometimes involving life-threatening pulmonary thromboembolism (PE). Additional conditions complicating the diagnosis are the presence of risk factors for PE in almost all patients with COVID-19 and the overlap of clinical presentation between PE and COVID-19. Objectives: We conducted a single-center study at the Heart and Brain Hospital, Pleven, from December 2020 to February 2021. It included 27 consecutively hospitalized patients with recent pneumonia caused by COVID-19 and clinical presentations corresponding to PE. Methods: The cohort was divided into two groups with and without a definitive diagnosis of PE, proven by CT pulmoangiography. The aim was to find the indicators predicting the presence of PE in patients with acute or post-acute COVID-19 conditions. Results: Our results showed that some ECG criteria, including S-wave over 1.5 mm in leads I and aVL (P = 0.007), Q-wave in leads III and aVF (P = 0.020), and D-dimer as a quantitative variable (P = 0.025), were independent predictors of PE. The RV/LV diameter ratios ≥ 1.0 and right ventricular dysfunction showed a sensitivity (Se) of 62.5%, specificity (Sp) of 100%, positive predictive value (PPV) of 100%, and negative predictive value (NPV) of 86.4% to verify the PE diagnosis. Besides, the D-dimer cutoff value of 1,032 ng/mL had an optimal Se of 87.5%, Sp of 57.9%, PPV of 46.7%, and NPV of 91.7% for PE diagnosis (P = 0.021). Conclusions: Against the background of acute and post-acute COVID-19 conditions, ECG and EchoCG criteria remain the PE predictors. We suggest that a higher D-dimer cutoff value be applied in COVID-19 and post-COVID-19 patients to confirm/dismiss PE diagnosis. | en |
