Enhanced NO and superoxide generation in dysfunctional hearts from endotoxemic rats.

Abstract

Free radicals have been implicated in the etiology of cardiac dysfunction during sepsis, but the actual species responsible remains unclear. We studied the alterations in myocardial nitric oxide (NO), superoxide, and peroxynitrite generation along with cardiac mechanical function and efficiency in hearts from lipopolysaccharide (LPS)-treated rats.
