Fear of graft rejection after heart transplantation – a nationwide cross-sectional cohort study

Background: Cellular rejection is most common 3–6 months after heart transplantation while chronic rejection, that is, cardiac allograft vasculopathy and malignancy are the most common causes of death in heart-transplant recipients beyond the third year after transplantation. However, the heart transplantation recipient’s perceived threat of graft rejection has never been explored. Aim: The aim was to explore perceived threat of the risk of graft rejection and its relationship to psychological wellbeing, fatigue, health literacy, adherence and self-efficacy 1–5 years after heart transplantation. Methods: In a nationwide, cross-sectional study that constituted part of the Self-management after thoracic transplantation project, 79 heart recipients (68% men and 32% women with a mean age of 52.6 years) were investigated after one year (n=28), two years (n=17), three years (n=11), four years (n=17) and five years (n=6). The instruments used were: the Perceived Threat of the Risk of Graft Rejection, the Psychological General Well-being, Self-efficacy for Managing Chronic Disease, the Multidimensional Fatigue Inventory, the Newest Vital Sign and the Basel Assessment of Adherence to Immunosuppressive Medication Scale. Results: Twenty-eight per cent of the heart transplantation recipients perceived graft rejection as a serious threat. Intrusive anxiety was low and 37% perceived the threat of the risk of graft rejection as being beyond their control. Heart transplant recipients with high level of fatigue and low psychological well-being reported stronger intrusive anxiety and less control. Conclusion: A perceived threat of the risk of graft rejection is present in the everyday lives of heart transplantation recipients and is strongly related to overall psychological well-being.
