Aims: Elderly men with androgen deficiencies are prone to develop late-onset depression. We investigated links between circulating androgens and depression, and their combined impact on outcome in men with chronic heart failure (CHF).
Methods and results: Serum total testosterone (TT) and dehydroepiandrosterone sulphate (DHEAS) were measured using immunoassays in 163 men with stable systolic CHF [age: 60 +/- 10 years, NYHA class (I/II/III/IV): 27/84/46/6] and 316 healthy men. Depression was assessed using Beck Depression Inventory (BDI) and defined as BDI > or =16 points. In men with CHF, reduced TT and DHEAS, advanced NYHA class, elevated N-terminal pro-B type natriuretic peptide (NT-proBNP), reduced glomerular filtration rate, and reduced haemoglobin independently predicted severity of depressive symptoms (all P < 0.05). Depression was present in 20, 37 and 77% of men with no androgen deficiency, either TT or DHEAS deficiency, and both androgen deficiencies, respectively (P < 0.0001). During follow-up (median: 28 months), there were 87 (53%) cardiovascular deaths or unplanned hospitalizations. TT and DHEAS deficiencies (defined as < or = the 10th percentile of serum androgen levels in healthy controls) and BDI > or =16 points independently predicted unfavourable outcome (all P < 0.05).
Conclusion: TT and DHEAS deficiencies predict severity of depression in men with CHF. Depression and combined androgen deficiencies are independently related to poor outcome in these patients.
