Depressive symptoms and risk of functional decline and death in patients with heart failure
Key result
Severe depressive symptoms linked to ~82% greater risk of six-month functional decline or death.
- 82% higher risk
- P=0.003 for trend
- n=391
Why the study?
Depression is an established risk factor for poor outcome in patients with coronary heart disease, but little is known of its role in patients with heart failure.
Are depressive symptoms associated with an increased risk of functional decline and death in patients with decompensated heart failure?
Key Points
- To assess the relationship between depressive symptoms and prognosis in heart failure patients.
- Prospective follow-up of 391 patients aged 50 and older with decompensated heart failure.
- Measured depressive symptoms using the Geriatric Depression Scale with levels categorized as mild, moderate, and severe.
- Outcomes were functional decline in activities of daily living and death at six months relative to baseline.
- Patients with severe depressive symptoms (>=11) had an 82% higher risk of functional decline or death compared to those with <6 symptoms (p=0.003 for trend).
- A graded association was observed between depressive symptom severity and both functional decline and mortality; however, mortality association was not statistically significant after adjustment.
Study Design
Type
Cohort (n=391)
Structured PICO
Are depressive symptoms associated with an increased risk of functional decline and death in patients with decompensated heart failure?
P
Population
391 patients ≥50 years of age admitted with decompensated heart failure, followed prospectively for six months.
E
Exposure
Presence and severity of depressive symptoms (measured by Geriatric Depression Scale, Short-Form)
C
Comparator
Lower levels of depressive symptoms (<6 symptoms)
O
Outcome
Composite of death or decline in activities of daily living (ADL) at six months relative to baselinecomposite
Main Result
Effect estimate: 82% higher risk
p-value: p=0.003 for trend
Increasing severity of depressive symptoms is a strong, graded negative prognostic factor for functional decline or death in older patients hospitalized with decompensated heart failure.

“For patients hospitalized for coronary artery disease or heart failure and who had diagnoses of anxiety or depression, treatment with psychotherapy, medication or both was associated with as much as a 75% reduction in hospitalizations or emergency room visits. In some cases, there was a reduction in death.”
DCDr. Cheryl CarminPsychologist and Director of Behavioral Cardiology Services
“This may be the first study to show that treating anxiety and depression with medication or psychotherapy has a significant impact on heart disease outcomes.”
“These impressive findings contrast starkly with the weight of evidence obtained from randomized controlled trials (RCTs) of treatments for depression or anxiety in patients with ischemic heart disease or heart failure. These trials have failed to produce much evidence that treating depression or anxiety improves medical outcomes in these patients. This raises the question of whether the results of Carmin et al.'s retrospective study may be attributable to selection biases or residual confounding.”
Implication
Depressive symptom assessment merits consideration in decompensated HF; leaves open whether treatment improves functional outcomes.

Vaccarino et al. (2001) conducted a cohort in decompensated heart failure (n=391). Depressive symptoms vs. <6 depressive symptoms was evaluated on death or decline in activities of daily living (ADL) at six months, relative to baseline (82% higher risk, p=0.003 for trend). Severe depressive symptoms (≥11 symptoms) were associated with an 82% higher risk of functional decline or death at six months compared to <6 symptoms (p=0.003 for trend).
