Relationship between parathyroid hormone and depression in heart failure

Area of Science:

• Cardiology
• Endocrinology
• Psychiatry

Background:

• Depression predicts rehospitalization and mortality in heart failure (HF).
• Parathyroid hormone (PTH) is a promising biomarker for HF outcomes.
• Investigating the link between depression and PTH in HF is crucial.

Purpose of the Study:

• To explore the association between depression and serum PTH levels in patients with systolic HF.
• To identify predictors of moderate to severe depression in this population.

Main Methods:

• 100 outpatients with systolic HF (LVEF < 40%) were studied.
• Assessed depression using Beck Depression Inventory-II (BDI).
• Measured serum PTH, brain natriuretic peptide (BNP), and C-reactive protein (CRP).

Main Results:

• 51% of patients had moderate to severe depression (BDI score > 18).
• Higher PTH levels were observed in depressed patients (133 pg/ml vs. 71 pg/ml).
• PTH, LVEF, NYHA class, CRP, and edema independently predicted depression severity.

Conclusions:

• Moderate to severe depression in systolic HF is associated with elevated PTH and CRP levels.
• Poor functional status and lower LVEF are linked to depression in HF.
• These associations may elucidate depression's role in HF hospitalization and mortality.
