Discontinuation of β-blockers in stable patients with previous myocardial infarction, preserved left ventricular ejection fraction, and no heart failure: a pooled analysis of individual patient data

LancetPublished

  • Pooled analysis of individual patient data from the ABYSS and SMART-DECISION randomised trials
  • non-inferiority
  • one-stage mixed-effects Cox model, trial as random effect
  • Median follow-up 3.0 years (2.3-3.8)

Median time from index MI to randomisation 3.6 years (IQR 1.6-7.5)

Authors' conclusion

In stable patients with previous myocardial infarction, left ventricular ejection fraction ≥40%, no heart failure, and no other indication for β-blocker therapy, discontinuation met the non-inferiority criteria for the primary and key secondary endpoints.
