The purpose of this study was to identify high priority problems experienced by informal caregivers when providing care for individuals with heart failure in the home. This secondary analysis was part of a cross-sectional, descriptive study using online self-report instruments (N = 530), including one researcher-developed item identifying top priority problems for heart failure caregivers. Content and quantitative data analyses were conducted. Performing multifaceted activities and roles that evolve around daily heart failure demands (n = 463) and maintaining caregiver physical, emotional, social, and financial well-being (n = 138) were the two most common themes experienced by caregivers of individuals with heart failure. Each of these two problems had several dimensions. Another theme was providing unending care (n = 40), with two dimensions.
