- W3174240175 abstract "Abstract Introduction Infection caused by SARS-CoV-2 has been shown to lead to significant procoagulant events, in some cases 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, as well as the overlap of the clinical presentation between PE and COVID-19. Materials and Methods: Тherefore we conducted a single-center study at the Heart and Brain Hospital, Pleven in the period December 2020-February 2021. It included 27 consecutively hospitalized patients with recent pneumonia caused by Covid-19 and clinical presentation referring to PE. 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 that predict the presence of PE in patients with acute or Post-acute COVID-19 conditions. Results: Our results show that part of the ECG criteria - S-wave over 1.5 mm in I lead and aVL (p = 0.007), Q-wave in III and aVF (p = 0.020), as well as the D-dimer as quantitative variable (p = 0.025) proved to be independent predictors of PE. The RV/ LV diameter ratios ≥1.0 as well as right ventricular dysfunction showed sensitivity 62.5%, specificity 100%, positive predictive value 100% and negative such 86.4% to verify the PE diagnosisЛ We suggest that the cut-off value of D-dimer of 1032 ng/ml has an optimal sensitivity (Se) of 87.5%, specificity (Sp) 57.9%, positive a predictive value (PPV) 46.7% and negative predictive value (NPV) of 91.7% for the diagnosis of PE (p = 0.021). Conclusion: Against the background of acute and Post-acute COVID-19 conditions ECG and EchoCG criteria remain predictive of PE. We suggest that a higher D-dimer cut-off value should be applied in COVID-19 and post-COVID-19 patients in order to confirm/dismiss the diagnosis PE." @default.
