Beta blockers after a heart attack: new findings

Beta blockers are traditionally used after a heart attack to reduce the risk of further events. However, new studies from 2024 and 2025 show that beta blockers do not provide any clear benefit in patients with normal heart pump function (left ventricular ejection fraction above 50%).

The most important findings:

• For people with mildly impaired pump function (between 40% and 50%), there is evidence of a possible benefit—however, these results are not yet conclusive and should be viewed with caution.
• The routine administration of beta blockers to all patients after a heart attack should be reconsidered.
• In particular, those with normal heart function are unlikely to benefit further and can thus avoid side effects.

Your cardiologist will advise you individually on whether beta-blocker therapy is appropriate for you.
