Heart failure & cardiomyopathies
The prognostic impact of follow-up cardiac metaiodobenzylguanidine imaging on left ventricular trajectory after acute decompensation
Authors' conclusion
Follow-up MIBG imaging after discharge could provide additional prognostic information in ADHF patients with recovered left ventricular function.
Study context
- Population
- Acute decompensated HF (ADHF) patients with reduced left ventricular ejection fraction (LVEF) <40%
- Participants
- 145 patients
- Exposure
- Late HMR at 6-month follow-up by LVEF trajectory
- HFcorEFn = 54
- HFparEFn = 43
- HFnorEFn = 48
- Outcome
- Cardiac events:
- Readmission for worsening heart failure (HF)
- Cardiac death
- Follow-up
- 4.3 ± 2.6 years
Main finding
As reported in the abstract
Cardiac events by late HMR at 6FUP · 4.3 ± 2.6 years
- 43 patients had cardiac events
- Lower late HMR at 6FUP associated with greater risk of cardiac events in recovered LVEF, especially HFparEF; not observed in HFnorEF
Observational data: associations, not effects.
Further findings
Late HMR at 6FUP by LVEF trajectory · 6 months
- Late HMR significantly greater in HFcorEF than in HFparEF and HFnorEF
