Maybe not as good as once thought…
A new study, published on August 30, 2025, in the New England Journal of Medicine, questions the need for beta-blockers after a heart attack in people with healthy heart function. Led by Dr. Borja Ibanez and the REBOOT-CNIC team in Spain and Italy, this trial looked at whether these drugs help patients with a left ventricular ejection fraction (LVEF) above 40%—a group often given beta-blockers based on older research.
This study showed that for those patients who have LVEF above 40% beta blocker medication did not reduce the reoccurence of another cardiovascular event when compared to a placebo. This is in stark contrast from past studies done before modern heart treatments became common which showed beta blockers improve long term health outcomes.
Hopefully this will mean fewer medications being prescribed. Fewer pills means fewer side effects like tiredness, dizziness, and fatigue. If you or someone you know has suffered a cardiovascular event and was placed on a beta blocker talk to your doctor to see what’s best for you.
