Utility of patient-reported perception of symptom change in patients with acute decompensated heart failure in predicting post-discharge clinical outcomes: insights from KCHF registry
- multicentre cohort study
Authors' conclusion
The patient-reported perception of symptom change at discharge was correlated with a composite of all-cause death or HF hospitalization at 1 year after discharge in patients admitted to the hospital for ADHF.
Study context
- Population
- Consecutive patients hospitalized due to acute decompensated heart failure (ADHF) in Japan (Kyoto Congestive Heart Failure study) who assessed their perception of symptom change during index hospitalization on a 7-point Likert scalestudy population, among 4056 consecutive patients hospitalized due to ADHF
- Participants
- 3,567 patients
- Exposure
- no, minimal, and moderate improvement groups relative to the marked improvement group
- marked improvement groupn = 1,602reference
- moderate improvement groupn = 1,659
- minimal improvement groupn = 240
- no improvement groupn = 66
- Outcome
- composite of:
- All-cause death
- HF hospitalization
- Follow-up
- 1 year
