Multiple biomarker strategy based on parathyroid hormone and natriuretic peptides testing for improved prognosis of chronic heart failure.

Biomarkers offer new perspectives for a more personalized management of patients with heart failure (HF). Hyperparathyroidism is common in HF patients and parathyroid hormone (PTH) testing might provide added value for the prognostication of HF patients. Our objectives were therefore to determine the efficiency of multiple biomarker strategy based on PTH and natriuretic peptides measurement for the risk stratification of patients with HF. Circulating concentrations of bioactive PTH 1-84 and natriuretic peptides, B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP), were measured with automated immunoassays in 45 healthy individuals and 137 HF patients with reduced left ventricular ejection fraction. Circulating levels of PTH 1-84 and natriuretic peptides were significantly increased in HF patients in comparison to HF patients. Over a long-term follow-up, baseline PTH 1-84 levels were related to the risk of cardiovascular death. Furthermore, in multiple biomarker approach, PTH measurement was additive to BNP and NT-proBNP testing for the cardiovascular risk assessment of HF patients. In conclusion, the combination of PTH 1-84 and natriuretic peptides testing improves the prognostication of HF patients and might allowed more personalized approach for risk stratification and treatment selection in HF patients.
