Effect of β-Blockers Beyond 3 Years After Acute Myocardial Infarction.

ABSTRACT: The optimal duration of β-blocker therapy in patients with acute myocardial infarction (AMI) is unknown. We aimed to evaluate the late effect of β-blockers in patients with AMI. We enrolled all consecutive patients who presented with AMI at Seoul National University Bundang Hospital, between June 3, 2003 and February 24, 2015. The primary end point was 5-year all-cause mortality, depending on the use of β-blockers at discharge, 1 year after AMI, and 3 years after AMI. Of 2592 patients, the prescription rates of β-blockers were 72%, 69%, 63%, and 60% at discharge and 1, 3, and 5 years after AMI, respectively. The patients who were receiving β-blocker therapy had more favorable clinical characteristics, such as younger age (62 versus 65 years; P<0.001). They received reperfusion therapy more
