Does beta-blocker therapy reduce mortality and morbidity in contemporary post-MI patients, particularly those with preserved LVEF?
The historical benefit of routine beta-blocker therapy post-MI is becoming less clear in the modern treatment era, particularly for patients with preserved LVEF.
Historical data strongly supported the benefits of beta-blocker therapy following a myocardial infarction (MI) for its efficacy in reducing mortality and morbidity. However, in the context of the progressive evolution of treatment strategies for MI patients, the apparent benefit of beta-blocker therapy is becoming less clear. In particular, its effectiveness in patients with preserved left ventricular ejection fraction is currently being challenged. Consequently, contemporary guidelines are now varying in their recommendations regarding the role of beta-blocker therapy in post-MI patients. This review aims to summarize and compare the largest and most influential studies from the prereperfusion era to modern practice regarding different health outcomes while highlighting the need for further research to clarify beta-blocker therapy's place in contemporary post-MI management.
