The purpose of this trial is to study the effects of preoperative antithrombin supplementation in patients undergoing cardiac surgery with cardiopulmonary bypass in order to maintain antithrombin levels in a range greater than 58% and, eventually, to decrease negative clinical outcomes during the ICU stay.

Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
