Background Tumor necrosis factor alpha (TNF alpha) plays an important role in the pathophysiology of heart failure. Recent studies have shown a beneficial effect of losartan in these patients. However, the effect of losartan on TNF alpha levels in heart failure has not yet been studied. We evaluated the effect of losartan on circulating TNF alpha levels and ejection fraction (EF) in patients with congestive heart failure.
