Abstract

Objective: To determine the prevalence and predictors of anxiety and depression in patients with heart failure due to Left Ventricular Systolic Dysfunction (LVSD).

Background: Psychological adjustment to Chronic Heart Failure (CHF) can be poor, with the prevalence of depression in out-patients ranging from 13% to 48%. The prevalence of anxiety disorders in this population is unknown and the factors that predict anxiety and depression are not well understood.

Methods: 100 out-patients from a community heart failure programme completed a clinical diagnostic interview--the Structured Clinical Interview (SCID-I), to evaluate anxiety and depression. Mean age was 67+/-11 years, 17% were women and 91% were NYHA Class II or III. Other standardised measures were of cognition, biomedical status, social support and previous physical and mental health history.

Results: The prevalence rates of anxiety and depression (all subtypes) were 18.4% and 28.6%, respectively. Predictors of depression included a reported history of mental ill-health and NYHA class. Predictors of anxiety included a reported history of mental ill-health, co-morbid physical illness (diabetes and angina) and NYHA class. Severity of LVSD did not predict either anxiety or depression.

Conclusions: Both anxiety and depression are common in CHF patients. The data on the predictors of poor psychological adjustment might assist in targeting bio-psychosocial intervention for patients who are at most at risk of anxiety and depression, within community CHF disease management programmes.
