Symptoms, depression, and quality of life in patients with heart failure

Background: Little is known about symptoms and their burden ill outpatients with chronic heart failure. Diverse symptoms may be associated with poor heart failure-related quality of life, and depression may be related to increased symptoms. Methods and Results: The number of symptoms and symptom distress (physical symptoms oil the Memorial Symptom Assessment Scale-Short Form), depression (Geriatric Depression Scale-Short Form),and heart fail Lire-related quality of life (Kansas City cardiomyopathy Questionnaire) were measured cross-sectionally ill 60 patients with heart failure from two Outpatient cardiology clinics. Patients experienced a mean of nine symptoms in the previous week. More than half reported shortness of breath, lack of energy, pain, feeling drowsy, or (try mouth. Ill unadjusted analyses, more severe depression was associated with a greater number of symptoms (r = 0.5 1, P < .0001) and greater overall symptom distress (r = 0.58, P < .0001). For each additional depression symptom, the number of symptoms reported increased by 0.6 after adjustment for age, race, and N-terminal pro-brain natriuretic peptide (P = .01). The number of symptoms accounted for 32% of the variance in quality of life (P < .0001). Conclusions: Patients with heart failure report a large number of distressing symptoms. Depression in patients with heart failure is associated with a greater number of symptoms, which in turn is associated with a decrease in heart failure-related quality of life. Treatment of depression and the diverse symptoms reported by patients with heart failure might significantly improve quality of life.
