Abstract
The importance of frailty in heart failure (HF) patients has been increasingly recognized because of its high prevalence and its significantly adverse impact on prognosis and quality of life. Due to the impact of frailty on both prognosis and treatment of HF patients, all patients with HF, regardless of their chronological age, should be evaluated for the presence of, or the risk for developing frailty. However, although several instruments are available, there is still no consensus as to which is the best method to assess frailty in patients with HF. Therefore, a validated and easy to apply instrument to assess frailty in HF patients in daily practice is warranted.
