摘要：

A variety of clinical and experimental investigations have suggested that tumor necrosis factor alpha (TNF-a) may play a role in the pathophysiology of heart failure. Serum levels of TNF-a are elevated in patients with heart failure, and both cardiac and infiltrating cells of the myocardium can produce this proinflammatory cytokine. Both cardiac myocytes and nonmyocytes also express receptors for TNF-a, and experimental studies on isolated cells, muscles, and transgenic models demonstrate the ability of TNF-a to recapitulate functional and biochemical alterations resembling that observed in human congestive heart failure. The intracellular pathways affected by TNF-a include production of ceramide and an alteration in calcium metabolism. Recent studies in both animal models and clinical investigations suggest that anti-TNF-a therapies may limit the pathophysiologic consequences of congestive heart failure.
