Abstract
Our knowledge of the pathophysiology of heart failure has advanced far beyond the classic concept of the hemodynamic overload model and associated neurohumoral changes. Current interest lies in understanding the fundamentals of cellular defects to identify new molecular targets for therapies. Some of the new target sites being explored are inflammatory cytokines, nitric oxide, oxidative stress and apoptosis during the remodelling processes such as cardiac hypertrophy and dilation. The present review provides an overview of the chemistry/biochemistry of free radicals as well as a discussion of some defense mechanisms that have evolved and adapted to combat these toxic oxygen species. The probable role of oxidative stress in the pathogenesis of heart failure both from animal data and heart failure patients is also presented.
