The appropriate use of biomarkers in heart failure.

ABSTRACT

Natriuretic peptides and troponins have been extensively studied and used in heart failure, and their value has been extensively discussed. Renal markers, such as cystasin-C, NGAL, and KIM-1, have shown growing utility in heart failure. The activation of compensatory pathways and ongoing hemodynamic changes result in the release of biomarkers that can be monitored to chart disease progression and possibly target for therapy.
