High PTH levels have been reported in patients with chronic heart failure (CHF). Similarly, its levels increase with aging and are related to impaired survival in elderly adults. However, its relationship with neuroendocrine activation and endothelial dysfunction in CHF has not been previously studied. Seventy-three CHF males with New York Heart Association (NYHA) classes II and III and 20 control subjects aged ≥ 55 yr were recruited. PTH, 25-hydroxyvitamin D [25(OH)D], N-terminal pro-brain natriuretic peptide (NT-pro-BNP), adiponectin, and osteoprotegerin were measured. Endothelial function (brachial flow mediated dilation), echocardiography, physical performance, and quality of life were assessed, as well. CHF patients had markedly increased serum PTH (77 ± 33 vs 40 ± 11 pg/ml, p<0.0001), NT-pro-BNP [1809 (2742) vs 67 (74) pg/ml, p<0.0001], adiponectin (17 ± 9 vs 10 ± 2 μg/ml, p<0.0001), osteoprotegerin, whereas 25(OH)D levels were decreased compared to controls. Increased PTH is positively correlated with NTpro- BNP (r=0.399, p<0.0001), adiponectin (r=0.398, p<0.0001), and osteoprotegerin, whereas negatively with 25(OH)D in CHF patients. Additionally, increased serum PTH was associated with endothelial dysfunction, echocardiographic variables of heart failure progression, impaired physical performance, and deteriorated quality of life. In a multivariate linear regression analysis, increased serum PTH was independently associated with neuroendocrine activation (NT-pro-BNP, adiponectin) and endothelial dysfunction in elderly CHF men (R2=0.455). Additionally, demonstrated relations with other well-established variables of heart failure severity suggest the potential role of serum PTH in the pathogenesis and non-invasive monitoring of heart failure progression. Future studies are needed to evaluate the predictive value of serum PTH for clinical outcomes as well as beneficial potential of PTH suppression in CHF patients.
