In journals for cardiac surgeons and anesthesiologists, the term heparin rebound has predominantly described an anticoagulant condition. In journals for cardiologists and internists, however, the term has been used to describe a procoagulant state. Because precision is one of the fundamental rules in medicine, it may be helpful to foster a more precise understanding of this term.
