The heightened state of vulnerability in these patients confers a greater risk of adverse outcomes after even minor stressors. Our aim was to assess the prevalence and prognostic significance of the frailty phenotype in patients referred for heart transplantation. (More)
BACKGROUND The aim of this study was to identify whether the addition of cognitive impairment, depression, or both, to the assessment of physical frailty provides better outcome prediction in patients with advanced heart failure referred for heart transplantation (HT). METHODS Beginning in March 2013, all patients with advanced heart failure referred to(More)
