Rationale and design of a randomised, controlled, multicenter trial investigating the effects of selective serotonin re-uptake inhibition on morbidity, mortality and mood in depressed heart failure patients (MOOD-HF)

Abstract

Background: Depression and chronic heart failure (CHF) are common conditions, both of which are clinically and economically highly relevant. Major depression affects 20-40% of CHF patients and predicts adverse outcomes in terms of quality of life, morbidity and mortality as well as health care expenditure, independent of other factors of prognostic relevance.

Aims: The purpose of the MOOD-HF trial is to clarify whether antidepressant pharmacotherapy improves outcome in CHF patients, and if so by which mechanism(s).

Methods: MOOD-HF is a prospective, randomised, double-blind, placebo-controlled, 2-armed, parallel-group multicenter trial investigating the effects of the serotonin re-uptake inhibitor (SSRI) escitalopram on morbidity and mortality (primary endpoint), severity of depression, anxiety, cognitive function, quality of life and health care expenditure in 700 patients with symptomatic systolic CHF and major depression diagnosed by structured clinical interview. All patients will receive optimised pharmacotherapy for CHF. Duration of follow-up, including close safety monitoring, is 12-24 months from randomisation.

Perspective: MOOD-HF is the first prospective randomised controlled trial to assess the effects of antidepressant pharmacotherapy on hard somatic endpoints, the mechanism(s) of action of SSRI treatment, as well as safety in New York Heart Association functional class II-IV CHF patients. The results are expected to promote the development of evidence-based recommendations for managing depression in the context of CHF.
