A Common β1-Adrenergic Receptor Polymorphism Predicts Favorable Response to Rate-Control Therapy in Atrial Fibrillation.
Summary of "A Common β1-Adrenergic Receptor Polymorphism Predicts Favorable Response to Rate-Control Therapy in Atrial Fibrillation."
In this study, we evaluated the impact of 2 common β1-adrenergic receptor (β1-AR) polymorphisms (G389R and S49G) in response to ventricular rate control therapy in patients with atrial fibrillation (AF).

Medical and Biotech [MESH] Definitions
Receptors, Adrenergic, Beta-3
A subclass of beta-adrenergic receptors (RECEPTORS, ADRENERGIC, BETA). beta-3 Adrenergic receptors are the predominant beta-adrenergic receptor type expressed in white and brown ADIPOCYTES and are involved in modulating ENERGY METABOLISM and THERMOGENESIS.
Receptors, Interleukin-1 Type I
An interleukin-1 receptor subtype that is involved in signaling cellular responses to INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The binding of this receptor to its ligand causes its favorable interaction with INTERLEUKIN-1 RECEPTOR ACCESSORY PROTEIN and the formation of an activated receptor complex.
Peak Expiratory Flow Rate
Measurement of the maximum rate of airflow attained during a FORCED VITAL CAPACITY determination. Common abbreviations are PEFR and PFR.
G-protein-coupled Receptor Kinase 2
A ubiquitously expressed G-protein-coupled receptor kinase subtype that has specificity for the agonist-occupied form of BETA-ADRENERGIC RECEPTORS. It may play an essential role in regulating myocardial contractile response.
Maximal Expiratory Flow Rate
The airflow rate measured during the first liter expired after the first 200 ml have been exhausted during a FORCED VITAL CAPACITY determination. Common abbreviations are MEFR, FEF 200-1200, and FEF 0.2-1.2.
