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.
Better methods of providing information for long-term survivors of stroke, and for addressing their emotional and psychological needs are required. Primary care could be a key setting for helping to provide more inclusive services for both patient and carer.
The ECHOES mortality data confirm the poor prognosis of patients suffering prevalent HF across the community with a mortality risk estimate of 9% per year. Borderline systolic dysfunction (EF 40-50%) on echocardiography carries a poor prognosis.
Objective To investigate the performance of a novel assay for N-terminal pro-brain natriuretic peptide (NT-proBNP) in diagnosing heart failure in various randomly selected general and high risk community populations. Design Community cohort study (substudy of the echocardiographic heart of England screening study). Setting Four randomly selected general practices in the West Midlands of England. Participants 591 randomly sampled patients over the age of 45, stratified for age and socioeconomic status and falling into four cohorts (general population, patients with an existing clinical label of heart failure, patients prescribed diuretics, and patients deemed at high risk of heart failure). Main outcome measure Sensitivity, specificity, positive and negative predictive values, likelihood ratios, and area under receiver operating characteristic curve for NT-proBNP assay in the diagnosis of heart failure. Results For NT-proBNP in the diagnosis of heart failure in the general population (population screen), a level of > 36 pmol/l had a sensitivity of 100%, a specificity of 70%, a positive predictive value of 7%, a negative predictive value of 100%, and an area under the receiver operating characteristic curve of 0.92 (95% confidence interval 0.82 to 1.0). Similar negative predictive values were found for patients from the three other populations screened. Conclusions This NT-proBNP assay seems to have value in the diagnosis of heart failure in the community. High negative predictive values indicate that the assay's chief use would be to rule out heart failure in patients with suspected heart failure with normal concentrations of NT-proBNP. Positive results may identify patients who need cardiac imaging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
