Key takeaways:

Beta-blocker use after heart attack in patients with preserved or mildly reduced heart function was assessed in three studies.

The benefit of beta-blockers appears most prominent with more reduced heart function.

Perspective from Christopher M. Kramer, MD

Two new trials and a meta-analysis presented at the European Society of Cardiology Congress put the spotlight on the use of beta-blocker therapy after myocardial infarction in patients with preserved or mildly reduced heart function.

One trial reported lower risk for CV outcomes with long-term beta-blocker therapy in patients after MI with left ventricular ejection fraction of at least 40%, while a second trial found no impact on outcomes, and a higher risk among women.
