N-terminal protype-B natriuretic peptide and Doppler diastolic variables are incremental for risk stratification of patients with NYHA class I-II systolic heart failure

In patients with systolic HF in NYHA functional class I and II, N-terminal proBNP and LV mitral flow and TD variables of diastolic dysfunction had a strong predictive power for the combined end point of all-cause mortality and HF-related hospitalizations.
