BACKGROUND: Heart failure and left ventricular systolic dysfunction (LVSD) are increasingly common disorders, with outcomes worse than many cancers. Evidence-based therapies, such as ACE inhibitors and beta-blockers, improve prognosis and symptoms, and reduce healthcare expenditure. However, despite the high prevalence and malignant prognosis, few studies have reported the impact of heart failure and LVSD on overall quality of life and, more crucially, have not researched the elderly or those in the community. METHODS: All patients attending the Echocardiographic Heart of England Screening (ECHOES) study of the prevalence of heart failure and LVSD in the community were assessed by clinical history and examination, electrocardiogram and echocardiography, and also completed the SF36 health status questionnaire. Quality of life in patients found to have heart failure, LVSD, and other cardiac and medical conditions are compared with the randomly selected general population sample. Data are generalisable to the UK. RESULTS: 6162 people in the community were screened in the ECHOES study, of whom 5961 (97%) completed the SF36. The health perceptions of 3850 people aged 45 years or older selected randomly from the population were compared with those of 426 patients diagnosed as having definite heart failure. Those with heart failure had significant impairment of all the measured aspects of physical and mental health, in addition to declines in physical functioning. Significantly worse impairment was found in those with more severe heart failure by NYHA class: indeed, NYHA functional class was closely correlated to SF36 score. Patients with asymptomatic left ventricular dysfunction and patients rendered asymptomatic by treatment had similar scores to the random population sample. Those with heart failure reported more severe physical impairment of quality of life than people giving a history of chronic lung disease or arthritis, with less impact on mental health than patients reporting depression. CONCLUSIONS: Patients with heart failure have statistically significant impairment of all aspects of quality of life, not simply physical functioning. The physical (role and functioning) health burden was significantly greater than that suffered in other serious common chronic disorders, whether cardiac or other systems. Optimising treatment to improve NYHA class appears to improve perceptions of quality of life for patients with heart failure. Given the dramatic decline in quality of life with heart failure, this end-point should be a much more important target for healthcare interventions, especially treatments such as ACE inhibitors and beta-blockers that are shown to improve quality of life.
