About

Viral infections provoke the systemic inflammatory response and cause an imbalance between the procoagulant and anticoagulant homeostatic mechanisms. Multiple pathogenic mechanisms are involved, including endothelial dysfunction, increased von Willebrand factor, Toll receptor activation, and tissue factor pathway activation. D-dimer levels greater than 1000 ng / mL are associated with an 18-fold increased risk of mortality. In this context, many patients may require prophylaxis or antithrombotic treatment with low molecular weight heparins. Currently, there is no validated scheme on the dose and timing of the use of antithrombotic drugs.

The study aims to identify the effect of two anticoagulant strategies (prophylactic and therapeutic) on the progression to ventilatory support or death in patients with COVID-19 infection who require hospital care.

Full description

Randomized clinical trial in patients with a confirmed infection by COVID-19 who require hospital treatment and subsequent ambulatory surveillance.

Study population. Patients with a diagnosis by PCR of COVID 19, over 18 years of age from the High Specialty Hospital of Ixtapaluca, who meet the inclusion criteria.

Statistic analysis. The student's T-test was carried out to identify the difference in the means of the quantitative variables between the groups. A value of P ≤ 0.05, 95% CI will be considered significant. For the hypothesis test, the chi-square test will be performed, considering a p≤ 0.05, 95% CI value to be significant.
