Heart failure (HF) ranks as one of the leading chronic disorders affecting health-related quality of life (HRQL).
1 Moreover, many patients with advanced HF attach greater importance to HRQL than they do to duration of life,
2 which is itself limited by HF. Accordingly, HRQL is an important end point in clinical trials that assess health care interventions aimed at controlling HF (eg, medication and disease management programs among such patients).
