Effect of long-term beta-blocker treatment following myocardial infarction among stable, optimally treated patients without heart failure in the reperfusion era: a Danish, nationwide cohort study

Study (30,177 stable, optimally treated MI patients, 82% of whom were on beta-blockers) found use of beta-blockers was not associated with reduced risk of CV death or recurrent MI vs no treatment (difference between groups 0.1% and 0.2% respectively, p>0.05 for both).
