Key result
β-blockers linked to improved cardiovascular outcomes in patients with preserved LVEF after MI.
Why the study?
To assess whether beta-blockers are associated with improved cardiovascular outcomes after myocardial infarction in patients with preserved left ventricular ejection fraction.
Do β-blockers improve cardiovascular outcomes after myocardial infarction in patients with preserved left ventricular ejection fraction?
Do β-blockers improve cardiovascular outcomes after myocardial infarction in patients with preserved left ventricular ejection fraction?
Supports β-blocker use post-MI with preserved LVEF; confirms prior RCT evidence and strengthens guideline recommendations.
