title: [Prognostic value of changes in concentration of brain natriuretic peptide, TNF-alpha factor and Interleukin-6 in chronic cardiac failure].
abstract: During 6 months therapy initial and final N-terminal pro-B-type natriuretic peptide. TNF-alpha, and IL-6 level in blood plasma were determined in 61 ischemic CHI cases with left ventricular ejection fraction below 40%. The patients were followed up for next 24.7 +/- 11.5 months. In period of 6 months following up associated with performed therapy 67.9% of patients showed a positive clinical effect, combined with a decrease of plasma pools of neurohumoral mediators (NM) in 51.4%-71.4% of cases (in dependence on studied NM). There were selected the 4 variants of combinations of clinical efficacy and NM dynamics which failed to coincide in a half of observations for NT-pro BNP and IL-6, and in a third for TNF-alpha. Multivariate analysis of conformities showed, that a decrease of all NM during therapy significantly relates with patient surviving. In a group with a decrease of plasma NT-pro BNP level associated with therapy during consequent following up no lethal outcome was recorded, compared to 16% in a group with a rise in NT-pro BNP (a = 0.2). Lethal outcome was fixed in 4.2% in a group with a decrease in TNF-alpha, compared to 33.3% in a group with elevation in TNF-alpha (a = 0.016); and in 5% in a group with a fall in IL-6, compared to 23.1% in a group with an elevation of IL-6 (a = 0.04).
