Redox and nitrosative regulation of cardiac remodeling

Heart disease is a major cause of death and morbidity worldwide, particularly so in industrialized nations. A major contributor to its varied pathophysiology is abnormal oxidative/reductive and nitrosative stress. While oxidant-scavenging therapies for cardiovascular disease have been disappointing to date, new insights into the precise sources of oxidative/nitrosative stress, its compartmentalized targets, and the modulators designed to control it are paving the way for a very different approach. This issue of the journal presents a Forum highlighting recent work from an international network of investigators that focuses on the role of oxidative/nitrosative stress in the remodeling heart.
