To evaluate the role of brain natriuretic peptide (BNP) in predicting the progression of heart failure (HF) after cardiac resynchronization therapy (CRT).


It has been shown that BNP predicts the prognosis and can guide the treatment of HF.


We studied 50 consecutive patients (61+/-10 years, 23 male) with HF (8 with ischaemic cardiomyopathy), NYHA class III, left bundle branch block, left ventricular ejection fraction (LVEF) </=35% (mean 24+/-6%) who underwent CRT. All patients were taking conventional HF therapy and were clinically stable. Plasma BNP levels were evaluated by two-site dual-monoclonal immunochemiluminescent assay before, and 1 month after CRT. The predictive value of BNP was assessed using univariate and multivariate regression analyses.


During follow-up (mean 19+/-12 months), HF progression was observed in 14 patients (11 were hospitalised and 3 died after worsening of HF). Multivariate analysis showed that BNP levels before (HR: 2.07; CI: 1.19-3.62; p=0.01) and 1 month after CRT (HR: 2.23; CI: 1.26-3.94; p=0.006) were significantly related to events. At 1 month, a BNP level >91.5 pg/ml had 89% sensitivity, 59% specificity, and negative and positive predictive values of 96% and 33%, respectively, for HF progression after 12 months.


HF patients with high BNP values after 1 month of CRT have worse prognosis during follow-up. Therefore, in these patients other therapeutic options should be considered.
