Description
Summary:	To conduct a comprehensive evaluation of coagulation profiles - via traditional and whole blood thromboelastometry tests - in COVID-19 positive vs. COVID-19 negative patients admitted to medical wards for acute pneumonia. We enrolled all consecutive patients admitted to Internal Medicine wards of Padova University Hospital between 7 March and 30 April 2020 for COVID-19-related pneumonia (cases) vs. non-COVID-19 pneumonia (controls). A group of healthy subjects acted as baseline for thromboelastometry parameters. Fifty-six cases (mean age 64±15 yrs, M/F 37/19) and 56 controls (mean age 76±11 yrs, M/F 35/21) were enrolled. Cases and controls showed markedly hypercoagulable thromboelastometry profiles vs. healthy subjects, mainly characterized by a significantly shorter propagation phase of coagulation (Clot Formation Time, CFT) and significantly increased maximum clot firmness (MCF) (p <0.001 in all comparisons). COVID-19 patients with pneumonia had significantly shorter CFT and higher MCF (p <0.01 and <0.05, respectively in all comparisons) vs. controls. Patients admitted to internal medicine wards for COVID-19 pneumonia presented a markedly prothrombotic state, which seems peculiar to COVID-19 rather than pneumonia itself.
