Risk Stratification in Chronic Heart Failure: Independent and Incremental Prognostic Value of Echocardiography and Brain Natriuretic Peptide and its N-terminal Fragment

In patients with CHF, Doppler echocardiography, Doppler tissue imaging, and NT-proBNP provide independent and incremental prognostic information. A combined use of echocardiography and NT-proBNP may help to improve risk stratification in this patient population.
