β-Blockers not associated with lower 1-year mortality post-AMI without HF/LVSD; leaves open need for RCTs before practice change.
Does β-blocker use reduce mortality in survivors of acute myocardial infarction without heart failure or ventricular dysfunction?
In survivors of acute myocardial infarction without heart failure or left ventricular systolic dysfunction, routine beta-blocker use was not associated with improved 1-year survival.
Dondo et al. (2017) studied this question. In patients without heart failure or left ventricular dysfunction after acute myocardial infarction, β-blockers were not associated with reduced mortality up to 1 year.
