Summary
The aim of the study is to determine whether discontinuation of β-blocker after at least 1 year of β-blocker therapy is noninferior to continuation of β-blocker in patients without heart failure (HF) or left ventricular systolic dysfunction after acute myocardial infarction (AMI).
Prospective, open-label, randomized, multicenter, noninferiority trial to determine whether discontinuation of β-blocker after at least 1 year of β-blocker therapy is noninferior to continuation of β-blocker in patients without HF or left ventricular systolic dysfunction after AMI.
Description
β-blockers have anti-ischemic, anti-arrhythmic, and anti-adrenergic properties. In order to reduce cardiovascular mortality and morbidity, current major guidelines recommend that oral treatment of β-blockers should be continued during and after hospitalization in patients with acute myocardial infarction (AMI) and without contraindications to β-blocker use.
A clinically important but difficult decision on β-blocker therapy after AMI is to determine the duration of β-blocker therapy after discharge in patients without heart failure (HF) or left ventricular systolic dysfunction. Previous studies for long-term β-blocker therapy after AMI were inadequate to derive definite conclusion because of small sample size and potential selection bias.
Therefore, the SMART-DECISION trial will investigate whether discontinuation of β-blocker after at least 1 year of β-blocker therapy is noninferior to continuation of β-blocker in patients without HF or left ventricular systolic dysfunction after AMI.
