摘要: We explore the pharmacogenomics of beta-blocker bucindolol by discussing relevant beta-1 adrenergic receptor (ADRB1) polymorphisms and recent studies. Through this, we will understand how may help patients with atrial fibrillation heart failure reduced ejection fraction (AF-HFrEF), which carries poor prognosis. Retrospective study Heart Failure: A Controlled Trial Investigating Outcomes Exercise Training trial revealed interaction between optimal dose ADRB1 Arg389 genotype for HFrEF clinical outcomes. Further, a combinatorial analysis in Beta-Blocker Evaluation Survival showed that Arg389Arg genotype, but not Gly carrier, was associated 40% lower mortality risk bucindolol. Finally, AF-HFrEF subgroup had greater rate reduction suggestion benefit. Therapeutic response to beta-blockers varies mechanism, setting (AF, HFrEF, AF-HFrEF). The ongoing Genotype-Directed Comparative Effectiveness Bucindolol Toprol-XL Prevention Symptomatic Atrial Fibrillation/Atrial Flutter Patients Failure prospectively identifies favorable prevent AF recurrence.
