atrial fibrillation/tyrosine

The aim of this study was to explore the changes in gene and protein expressions of tyrosine hydroxylase (TH) and growth-associated protein 43 (GAP43) in aging atrial fibrillation patients of Xinjiang Uygur and Han nationality, and the significance of the changes. Real-time polymerase chain reaction

BACKGROUND Emerging evidence has strongly implicated hereditary determinants for atrial fibrillation (AF). Loss-of-function mutations in KCNA5 encoding the ultrarapid delayed rectifier potassium current I(Kur) have been identified in AF families. OBJECTIVE The purpose of this study was to determine

Background Chronic intermittent hypoxia ( CIH ) is a distinct pathological mechanism of obstructive sleep apnea ( OSA ), which is recognized as an independent risk factor for cardiovascular diseases. The aims of this study were to ascertain whether CIH induces atrial fibrillation ( AF ), to

BACKGROUND Chronic atrial fibrillation (AF) leads to heterogeneous autonomic nerve innervation termed neural remodeling. The quantitative changes in neural density as a function of autonomic remodeling and its association with sustained AF has not been previously determined. RESULTS Seven dogs

OBJECTIVE Atrial fibrillation (AF) is the most common rapid cardiac arrhythmia associated with high morbidity and mortality. Stimulation of the sympathetic nerve is involved in AF occurrence. The gap junction protein connexin 43 (Cx43) plays a key role in electrical conduction velocity in cardiac

Ibrutinib, an irreversible inhibitor of Bruton tyrosine kinase (BTK), is a novel drug that has shown significant efficacy and survival benefit for treatment of various B-cell malignancies. The primary objective of the present study was to investigate the efficacy of ibrutinib therapy in various

Background Ibrutinib is a Bruton's tyrosine kinase inhibitor, which is United States Food and Drug Administration (FDA)-approved for chronic lymphocytic leukemia, mantle cell lymphoma, and Waldenström's macroglobulinemia. Ibrutinib is associated with atrial fibrillation and bleeding events. Our aim

BACKGROUND Atrial fibrillation (AF) leads to structural and neural remodeling in the atrium, which enhances AF complexity and perpetuation. Renal denervation (RDN) can reduce renal and whole-body sympathetic activity. Aim of this study was to determine the effect of sympathetic nervous system

There has been a significant shift in the management of B cell malignancies over the past decade. Initial strategies involving the use of systemic chemotherapies have been gradually replaced by more targeted therapies to improve survival and overall tolerability. Bruton's tyrosine kinase inhibitors

High thoracic epidural anesthesia (HTEA) blocks the afferent and efferent cardiac sympathetic nerve fibers and may affect atrial electrophysiological characteristics and nerve sprouting in patients with atrial fibrillation (AF). In this study, 18 dogs were randomly divided into a control group (n =

BACKGROUND Chronic left ventricular myocardial infarction (LVMI) promotes atrial and pulmonary veins (PV) sympathetic nerve sprouting. OBJECTIVE To test the hypothesis that sympathetic stimulation with tyramine initiates atrial fibrillation (AF) by early after depolarization (EAD)-mediated triggered

OBJECTIVE This study aims to explore the effects of renal sympathetic denervation (RSD) on atrial fibrillation (AF) inducibility and sympathetic activity induced by acute atrial ischemia/infarction. METHODS Acute ischemia/infarction was induced in 12 beagle dogs by ligating coronary arteries that

The study aimed to observe the effects of pacing on the atrial effective refractory period (AERP), inducibility of atrial fibrillation (AF), and changes of atrial autonomic neural remodeling (ANR) by rosuvastatin intervention on the acute model of rapid-pacing-induced AF. Thirty rabbits were
