title: [N-terminal fragment of the brain natriuretic peptide and proinflammatory cytokines in patients with ischemic heart disease].
abstract: OBJECTIVE
  To determine plasmic concentrations of NT-proBNP, TNFalpha and IL-6 in patients with coronary heart disease (CHD) complicated with chronic cardiac failure (CCF); to compare these parameters with hemodynamic and functional ones.
  
  
  METHODS
  A total of 157 CHD patients (84.1% males, mean age 54.3 +/- 6.8 years) were divided into 3 groups matched by sex and age according to the presence of CCF and left ventricular (LV) or systolic dysfunction.
  
  
  RESULTS
  CCF patients with LV dysfunction or intact LV function had much higher plasmic concentrations of neurohumoral mediators than CHD patients without CCF. A plasmic NT-proBNP level over 1000 fmol/ml was associated with a 5.5-fold increase in the relative risk of LV diastolic dysfunction for CCF patients (rR 5.6; 95% CI 1.4-30.0; p = 0.0065) while an IL-6 level over 6.1 pg/ml was associated with a 9-fold increase in this risk (rR 8.9; 95% CI 2.3-35.4; p = 0.00001). Plasmic NT-proBNP and IL-6 levels went up in correlation with a CCF functional class. A plasmic level of TNFalpha correlated with anginal functional class.
  
  
  CONCLUSIONS
  Changes in plasmic levels of the above neuromediators are associated with changes in some LV function and functional parameters of CCF patients.
