In older adults, performance measures are well established and commonly used as part of geriatric assessment to evaluate physical and cognitive functioning. Performance-based measures may be particularly beneficial in older adults with heart failure to monitor serial changes in physical function. Performance measures in clinical settings require staff time but little training, space, equipment, or risk. As performance measures become more common in practice settings, MDC thresholds may need to be re-evaluated based on the characteristics of the population [67].

For persons with heart failure whose screening outcomes suggest MCI, more comprehensive neuropsychological testing should be available as well as provision of resources to optimize functional independence. Early identification of impaired cognition may lower risk of poor self-management through simplification of medication regimens or providing resources to help manage other regimens essential for optimal heart failure care. It is also important to recognize that depressive symptoms are common in persons with heart failure and are highly correlated with cognitive impairment in this population. Screening for depressive symptoms therefore, may also enhance identification of persons with heart failure at risk for frailty [4,28].

Conclusion

Effective appraisal and development of effective interventions are essential in older adults with heart failure who are at high risk for frailty and cognitive impairment. This will become increasingly important as the population ages and the incidence of heart failure rises proportionately. Although curative treatments for frailty and cognitive impairment are not available, interdisciplinary interventions such as exercise and comprehensive geriatric assessment may improve outcomes in older persons with heart failure [68]. Information gained from objective, simple, inexpensive physical performance measures, when used in combination with cognitive screening, may enhance the ability to evaluate change that signal onset of frailty or cognitive impairment [54,69,70]. The high morbidity and mortality associated with frailty and cognitive impairment indicate that it should be a priority for future research as a strategy to improve clinical outcomes, enhance quality of life, and lower health care costs in this growing population.
