Anticoagulant fondaparinux lowers risk of major bleeding events, death in heart attack patients

Patients who experienced a certain type of heart attack who received the anticoagulant fondaparinux had a lower risk of major bleeding events and death both in the hospital and after six months compared to patients who received low-molecular-weight heparin (LMWH), although both groups had similar rates of subsequent heart attack or stroke, according to a study in the February 17 issue of JAMA.

Reducing bleeding events in patients receiving antithrombotic therapy is important since bleeding events are associated with increased mortality. Fondaparinux was associated with reduced major bleeding events and improved survival compared with LMWH (a class of anticoagulant medications) in a large randomized clinical trial involving patients with non-ST-segment elevation myocardial infarction (NSTEMI; a certain pattern on an electrocardiogram following a heart attack). Large-scale experience of the use of fondaparinux vs LMWH outside of a clinical trial setting has been lacking, according to background information in the article.

Karolina Szummer, M.D., Ph.D., of the Karolinska Institutet, Stockholm, Sweden, and colleagues analyzed data from a Swedish registry that included 40,616 patients with NSTEMI who received in-hospital treatment with fondaparinux or LMWH between September 2006 through June 2010, with follow-up through December 2010.
