1 Screening of Cardiovascular Complications in Patients With COVID-19

Patients with COVID-19 in the Intensive Care Unit (ICU) or hospitalized with severe form have a poor prognosis (almost 30% rate of death). They present often a high cardiovascular risk profile (almost 30% of hypertension and 19% of diabetes). Troponin has been described to be elevated in a high proportion of patients (one fifth of all patients and 50% of non-survivors) suggesting the possibility of cardiomyopathies. High levels of DDimers (81% of non survivors) and fibrin degradation products are also associated with increased risk of mortality suggesting also the possibility of venous thromboembolism. Therefore, screening for cardiomyopathies and venous thromboembolism could represent an important challenge for patients with COVID-19 management.

3 Incidence of Acute Pulmonary Embolism in Covid-19 Patients on CT Angiography and Relationship to D-dimer Levels

Reports of acute pulmonary embolism (APE) associated with COVID-19 have emerged in the literature. For example, Chen et al. described 25 pulmonary CT angiograms examinations from 1008 COVID-19 patients; 10 were positive for pulmonary embolism mostly as segmental or sub-segmental APE. Case reports of APE in Covid-19 patients have been published. Cui et al. found an incidence of deep venous thrombosis in intensive care unit (ICU) patients with severe Covid-19 pneumonia near to 25% (20/81), however without any correlation with potential APE. Despite these initial reports, it is not clear whether APE is more frequent in Covid-19 patients or if the association is just random. In favor of the former, D-dimer levels have been reported as elevated in patients with Covid-19 by two studies, and it has been suggested an independent association between the severity of the disease and the level of D-dimer. Finally, Tang et al. showed that anticoagulant therapy is associated with a decreased mortality at Day-28 in severe Covid-19 patients, in favor of a possible associated coagulopathy. The purpose of this study is to describe the rate of pulmonary embolus in patients classified as COVID-19 infection and who underwent chest CT angiography. The purpose of this study is to describe the rate of pulmonary embolus in patients classified as COVID-19 infection and who underwent chest CT angiography.

4 Effectiveness of Weight-adjusted Prophylactic Low Molecular Weight Heparin Doses Compared With Lower Fixed Prophylactic Doses to Prevent Venous Thromboembolism in COVID-2019. The Multicenter Randomized Controlled Open-label Trial COVI-DOSE

Worldwide observational studies indicate a significant prothrombogenic effect associated with SARS-CoV-2 infection with a high incidence of venous thromboembolism (VTE), notably life-threatening pulmonary embolism. According to recommendations for acute medical illnesses, all COVID-19 hospitalized patients should be given VTE prophylaxis such as a low molecular weight heparin (LMWH). A standard prophylactic dose (eg. Enoxaparin 4000IU once daily) could be insufficient in obese patients and VTE has been reported in patients treated with a standard prophylactic dose. In COVID-19 patients, guidelines from several international societies confirm the existence of an hypercoagulability and the importance of thromboprophylaxis but the "optimal dose is unknown" and comparative studies are needed. In view of these elements, carrying out a trial comparing various therapeutic strategies for the prevention of VTE in hospitalized patients with COVID-19 constitutes a health emergency. Thus, we hypothesize that an increased prophylactic dose of weight-adjusted LMWH would be greater than a lower prophylactic dose of LMWH to reduce the risk of life-threatening VTE in hospitalized patients. The benefit-risk balance of this increase dose will be carefully evaluated because of bleeding complications favored by possible renal / hepatic dysfunctions, drug interactions or invasive procedures in COVID-19 patients. This multicenter randomized (1:1) open-label controlled trial will randomize hospitalized adults with COVID-19 infection to weight-adjusted prophylactic dose vs. lower prophylactic dose of LMWH.

6 Study of the Prevalence of Deep Vein Thrombosis in Patients Hospitalized in Intensive Care for Acute Respiratory Failure Linked to Pneumonia Documented With SARS-COV2

Coronavirus 2 (SARS-CoV2) has been identified as the pathogen responsible for severe acute respiratory syndrome associated with severe inflammatory syndrome and pneumonia (COVID-19). Haemostasis abnormalities have been shown to be associated with a poor prognosis in these patients with this pneumonia. In a Chinese series of 183 patients, the hemostasis balance including thrombin time, fibrinogenemia, fibrin degradation products and antithrombin III were within normal limits. Only the D-Dimer assay was positive in the whole cohort with an average rate of 0.66 µg / mL (normal <50 µg / mL). These hemostasis parameters were abnormal mainly in patients who died during their management; the levels of D-dimers and fibrin degradation products were significantly higher while the antithrombin III was reduced. The findings on the particular elevation of D-dimers in deceased patients as well as the significant increase in thrombin time were also reported in another series. Higher numbers of pulmonary embolisms have been reported in patients with severe form of SARS-COV2 (data in press). This research is based on the hypothesis that the existence of deep vein thrombosis (DVT) could make it possible to screen patients at risk of pulmonary embolism and to set up a curative anticoagulation. The main objective is to describe the prevalence of deep vein thrombosis in patients hospitalized in intensive care for acute respiratory failure linked to documented SARS-COV2 pneumonia, within 24 hours of their admission.

8 Prevalence and Severity of Venous Thromboembolism in a General Population During the COVID-19 Pandemic

The purpose of this study is to investigate the prevalence of venous thromboembolism in a regional health care system (Region Östergötland, Sweden) before and during the SARS-COV-2 pandemic. In a retrospective observational study, we will review patient data, diagnostic data and treatment data over a three-month period since the onset of the SARS-COV-2 pandemic. This data will be compared with data from the corresponding time frame during the years 2015 to 2019.

11 Registry of the Evolution of Diagnosed and/or Hospitalized Patients for Pulmonary Embolism During the Covid-19 Pandemic: Retrospective and Prospective Multicentric Study.

The purpose of the study COVID-EP is to classify all the complications occurring after the diagnosis of pulmonary embolism in patients tested initially COVID-19 positive and negative by RT-PCR (on nasopharyngeal sample) during the peak of the pandemic in France (April 2020). The patients will be followed for 1 year in order to provide clinical and paraclinical data not yet published in the literature. In order to secondarily confirm the COVID-19 status of initially negative COVID-19 patients (by RT-PCR), a serology test will be performed. The collected complications will then be compared between each of the 3 following groups: [PCR-COVID 19-Neg & Sero-COVID 19-Neg] versus [PCR-COVID 19-Neg & Sero-COVID 19-Pos] versus [PCR-COVID 19-Pos].
