Summary

The primary aim of this study was to describe the prevalence and time course of the occurrence of protamine/heparin antibodies in patients undergoing cardiac surgery on cardiopulmonary bypass. The second aim was to identify triggers of immunization. The third aim of this study was to evaluate a potential clinical impact of protamine/heparin antibodies and their platelet-activating properties leading to thromboembolism and other adverse outcomes.
