Heart failure is a common and increasing public problem. Neurohormonal activation plays a role in the pathophysiology of heart failure, but is probably also affected by cytokines. We studied 75 patients with heart failure NYHA functional class II and III-IV, who were treated with angiotensin converting enzyme inhibitor (enarenal), diuretics (furosemide) and digoxine. Their mean age was 63.9 years/range 65-86/, left ventricular ejection fraction in the patients NYHA functional class II and III-IV classes was 68.9% and 47.3% respectively; 12 were females. Significant improvements in NYHA classification were shown. The levels plasma TNF-alpha (tumor necrosis factor-alpha) and interleukin-6 (IL-6) were analysed before and after therapy. The authors showed increased plasma levels TNF-alpha and IL-6 in patients with chronic heart failure. After the treatment the plasma IL-6 levels decreased only in the patients III-IV NYHA functional classes, whereas the treatment had no effect on the plasma TNF-alpha levels.
