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.

2 Increased Risk of Venous Thromboembolism and Higher Hypercoagulable State in Patients Recovered in Intensive Care Unit and in Medical Ward for Coronavirus Disease 2019 (COVID-19)

The aim of this study is to verify if patients admitted to hospital in a medical division and in the intensive care unit for a COVID-19 infection are at higher risk of developing a VTE complication and if they actually present an increased hypercoagulable state.

3 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.

4 Risk of Venous Thromboembolism in Critically Ill Patients With Severe COVID-19

Severe COVID-19 patients at a high risk of venous thromboembolism. We studied patients in 2 intensive care units of university hospitals in Barcelona and Badalona, Spain. We performed a cut-off screening of deep venous thrombosis (DVT) with bilateral duplex ultrasound to 230 patients.

5 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.

6 A Multicenter, Randomized-Controlled Trial to Evaluate the Efficacy and Safety of Antithrombotic Therapy for Prevention of Arterial and Venous Thrombotic Complications in Critically-Ill COVID-19 Patients

This is a multicenter, open-label, 2x2 factorial, randomized-controlled trial in critically-ill patients with novel coronavirus disease 2019 (COVID-19) evaluating the efficacy and safety of full-dose vs. standard prophylactic dose anticoagulation and of antiplatelet vs. no antiplatelet therapy for prevention of venous and arterial thrombotic events.

7 Utilização da Enoxaparina em Dose Anticoagulante em Pacientes Hospitalizados Com síndrome respiratória Aguda Grave Por COVID-19

Published papers evaluating coagulopathy on COVID-19 patients indicate a higher incidence of thromboembolic events, sometimes, as high as 20%. Such events increase ICU admissions and are associated with death. Considering the importance of thromboembolic events concurring to deteriorate clinical state, we propose to conduct a parallel pragmatic open-label randomized controlled trial to determine the effect of therapeutic anticoagulation compared to standard care in hospitalized patients with COVID-19 and with low oxygen saturation.
