Eplerenone in patients with myocardial infarction and "mid-range" ejection fraction: An analysis from the EPHESUS trial
BACKGROUND: Trials using mineralocorticoid receptor antagonists (MRAs) in myocardial infraction (MI) without heart failure (HF) or systolic impairment have been underpowered to assess morbidity-mortality benefit. In EPHESUS 6632 patients were included, of whom 11% had an ejection fraction (EF) of ...
G protein-coupled receptor kinase 2 (GRK2) as a multifunctional signaling hub
Accumulating evidence indicates that G protein-coupled receptor kinase 2 (GRK2) is a versatile protein that acts as a signaling hub by modulating G protein-coupled receptor (GPCR) signaling and also via phosphorylation or scaffolding interactions with an extensive number of non-GPCR cellular ...
This paper discusses the evolving concept of atrial myopathy by presenting how it develops and how it affects the properties of the atria. It also reviews the complex relationships among atrial myopathy, atrial fibrillation (AF), and stroke. Finally, it discusses how to apply the...
