Authors' conclusion

Among patients who received beta-blocker therapy beyond the first year after a myocardial infarction, discontinuation of beta-blocker therapy was noninferior to continuation with respect to a composite of death from any cause, recurrent myocardial infarction, or hospitalization for heart failure.

Study context

Population
Stable patients after MI with LVEF ≥40% and no HF, on beta-blocker therapy for ≥1 year after MI
Participants
2,540 patients
Comparison
Beta-blocker discontinuation vs continuation
  • Discontinuationn = 1,246
  • Continuationn = 1,294reference
Primary endpoint
Composite of:
  • All-cause death
  • Recurrent MI
  • Hospitalisation for HF
Follow-up
Median 3.1 years

Primary result

As reported in the abstract

median follow-up 3.1 years (IQR 2.5 to 3.5)

Hazard ratio

0.80

95% CI 0.57–1.13

P = 0.001 for non-inferiority

Events by treatment group

Discontinuation vs Continuation
HR 0.80 (95% CI 0.57–1.13); P for non-inferiority = 0.001

Safety

Serious adverse events

Similar incidence in the two groups
