Study Summary

Heparin is a drug that is widely used to prevent and treat blood clotting. Individuals undergoing cardiopulmonary bypass surgery are administered high doses of heparin, and some of them develop antibodies to the drug. This immune response can lead to the formation of blood clots, setting the stage for a potential heart attack or stroke. The purpose of this study is to evaluate how often an immune response to heparin leads to the formation of blood clots in individuals who have had heart surgery.
