Heart failure (HF) is a life-limiting condition with a poor prognosis and unpredictable disease trajectory. HF brings physical and emotional challenges for patients and their carers. Predominantly the informal carer population consists of older females, however, caring is evolving as longevity increases and complex conditions are becoming more commonplace. Consequently, more men and younger people are contributing to daily care. The aim of this study was to explore the positive as well as negative dimensions of caring in HF across a range of carer characteristics.
