Natriuretic peptides in heart failure with preserved ejection fraction.

Timely diagnosis, early introduction of appropriate treatment, accurate risk stratification, and optimal titration of therapy are all key to the management of acute and chronic heart failure (HF). Plasma concentrations of the cardiac natriuretic peptides (NPs) are valuable aids in each of these elements of care. However, most data are derived from cohorts with undifferentiated HF or HF with reduced ejection fraction (HFREF), and the performance and best application of NPs in HF with preserved ejection fraction (HFPEF) is less certain. This review outlines the evidence for use of NPs in the evaluation and management of HFPEF.
