Chronic heart failure patients often experience significant functional impairments. A better understanding of the biopsychosocial correlates of functional status may lead to interventions that improve quality of life in this population. Social isolation, mood disturbance, low socioeconomic status, and non-White ethnicity were evaluated as possible correlates of impaired functional status in 2,992 U.S. patients with left ventricular ejection fractions (LVEFs) ≤ 35%. Even after controlling for age and clinical characteristics, all of the psychosocial variables examined were significant predictors of risk for experiencing severe limitations in intermediate and social activities of daily living at 1 year, with adjusted odds ratios in the 1.5-2.0 range. The ability of psychosocial characteristics to predict future functional status was also independent of baseline functional status, comorbid medical conditions, and deterioration in heart failure signs and symptoms over the intervening year. These results suggest that psychosocial factors influence patient functional status even in the later phases of cardiac disease.
