Objectives
Narrative objectives1
The purpose of this study is to exploratorily investigate the association between sympathetic nervous system- and beta-adrenergic receptor-related biomarkers, heart rate trajectory, left ventricular remodeling indices, and heart failure-related events, with a focus on beta-blocker therapy, in patients after acute myocardial infarction.
