Heart failure (HF) is a disease of the elderly. In people aged>65years, it is the most common cause of rehospitalisations [1]. Nearly half of the patients diagnosed with HF will be frail (44.5%, 95% CI, 36.2%–52.8%) [2]. Not only is the prevalence of frailty high in HF patients, older persons with frailty are also at increased risk of developing new onset HF [3]. However, frailty is not only associated with the elderly as it can also occur in younger persons (aged <60 years) with HF [3]. The presence of frailty in HF patients accelerates disease progression of HF and increases their risk of rehospitalisation, mortality and functional decline at one year [4].
