Background: Earlier end‐of‐life communication is critical for people with heart failure given the uncertainty and high‐risk of mortality in illness. Despite this, end‐of‐life communication is uncommon in heart failure. Left unaddressed, lack of end‐of‐life discussions can lead to discordant care at the end of life. Objective: This study explores patients' and caregivers' understanding of illness, experiences of uncertainty, and perceptions of end‐of‐life discussions in advanced illness.
