study to evaluate the mortality reduction of enoxaparin in hospitalized acutely ill medical receiving enoxaparin

Conditions: Acute Illness

Summary: the primary objective: * to demonstrate in patients hospitalized for an acute medical illness that enoxaparin with graduated elastic stockings is superior to enoxaparin-placebo with graduated elastic stockings on overall mortality at day 30 after randomization. the secondary objective: * to compare, in patients hospitalized for an acute medical illness, enoxaparin with graduated elastic stockings versus enoxaparin placebo with graduated elastic stockings on overall mortality at day 90 after randomization. * to evaluate the safety of enoxaparin vte prophylaxis in patients hospitalized for acute medical illness with respect to major hemorrhage, total bleedings, heparin induced thrombocytopenia, adverse events and serious adverse events .
