Authors' conclusion

Results of this post hoc analysis of the FINEARTS-HF randomized clinical trial reveal that in this contemporary HFmrEF or HFpEF cohort, sudden death was preceded by modest worsening of symptoms, declining quality of life, and rising natriuretic peptide levels, suggesting many of these events may not have been entirely sudden. However, similar deterioration preceding other modes of death suggests limited specificity for sudden death.

Study context

Population
Symptomatic HF with LVEF ≥40%, NYHA II–IV and elevated NT-proBNP (heart failure with mildly reduced ejection fraction (HFmrEF) or HF with preserved ejection fraction (HFpEF)), enrolled 2020–2023
Participants
6,001 participants
Comparison
Trajectories before sudden death vs before other modes of death and survival
  • Sudden deathn = 215
Primary endpoint
Longitudinal trajectories of NYHA class, KCCQ-TSS and NT-proBNP preceding sudden death vs survivors and other modes of death
