title: Should patients with chronic heart failure be treated with "statins"?
abstract: There are a number of theoretical reasons as to why 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) should be prescribed to patients with chronic heart failure (CHF). These agents are proven to prevent coronary heart disease, the major etiological factor in the development of CHF. Potential additional effects of these agents include inhibition of proinflammatory cytokine activity and other potential beneficial effects on cardiac remodeling. However, there are also possible adverse effects of this strategy, supported by the overriding observation that low plasma lipid levels portend a poorer prognosis in patients with established CHF. Potential mechanisms by which statins may directly confer adverse effects include a reduction in levels of the antioxidant ubiquinone and an increase in blood endotoxin levels, both of which may contribute to CHF disease progression. Given these uncertainties, an answer to the question of whether or not therapy for CHF should include statins requires a definitive clinical trial. The importance of such a trial is further highlighted by the already commonplace usage of statins amongst patients with CHF.
