Biomarker guided therapy for heart failure: focus on natriuretic peptides

The management of heart failure remains challenging despite many therapeutic advances. Rigorous clinical trial evidence supports administration of multiple therapies, but utilization of evidence-based treatment remains inconsistent and suboptimal. Disease management programs appear effective, but remain costly and difficult to implement in today’s care system. Another approach involves optimizing therapy based on serial monitoring of cardiac biomarkers. Emerging results suggest that guiding therapy based on serial changes in natriuretic peptides may be an effective strategy. Although pilot work has provided encouraging results, appropriately designed, large-scale, prospective randomized trials are needed to confirm these preliminary findings and definitively establish this therapeutic approach.
