Heart Failure is a complex neurohumoral and inflammatory syndrome. Stu
dies have shown that proinflammatory cytokines (interleukin-1, interle
ukin-2, interleukin-6, and tumor necrosis factor) are involved in card
iac depression and in the complex syndrome of heart failure. Understan
ding the involvement of these cytokines may enable us to reverse cardi
ac depression and heart failure with the use of monoclonal antibodies
directed against specific cytokines that may block the downhill progre
ssion of heart failure.
