Heart failure is a leading cause of hospital admission, particularly in older adults. The RELAX-AHF study found that worsening symptoms (worsening heart failure) during hospitalization can lead to longer stays and increased risk of readmission or death. Targeting worsening heart failure may help reduce these adverse outcomes.
