OBJECTIVE: The aim of our study was to select the most relevant markers of impaired left ventricle (LV) function in patients with heart failure (HF) symptoms due to severe chronic mitral regurgitation (MR). METHODS AND RESULTS: Thirty-six patients with decompensated HF due to severe MR underwent echocardiography, 6-minute walk test (6MWT) and measurements of plasma renin activity, angiotensin II, aldosterone, noradrenaline (NA), brain natriuretic peptide (BNP), tumour necrosis factor alpha (TNFalpha) with its receptors, and interleukine-6. Patients presented with significant neurohumoral/cytokine activation. By stepwise multiple regression analysis the strongest prediction model for 6MWT included LVEDVI (R2 = 0.95, P = 0.024), BNP (R2 = 0.67, P = 0.0006), IL-6 (R2 = 0.90, P = 0.044); for BNP: 6MWT (R2 = 0.36, P = 0.003), LA (R2 = 0.56, P = 0.0077), LVESVI (R2 = 0.83, P = 0.0072); for NA: EF (R2 = 0.4 1, P = 0.036), and for TNFalpha: LVESVI (R2 = 0.65, P = 0.003). CONCLUSIONS: 6MWT and neurohumoral markers (mainly BNP, but also NA and TNFalpha) are good predictors of the degree of LV remodelling, showing an independent correlation with the level of LV dilatation/dysfunction in chronic severe MR.These assessments may supplement standard echocardiography in LV decompensation due to severe MR.
