Association between -44G/A and +71A/G polymorphisms in the connexin 40 gene and atrial fibrillation in Uyghur and Han populations in Xinjiang, China
Correlation analysis between the delayed rectifier potassium channel KCNE1 (G38S) polymorphism and atrial fibrillation among the senior Uygur population in Xinjiang
Current resources to support genetic screening among the Uygur population in Xinjiang territory for atrial fibrillation (AF) have not been well established and large-scale epidemiological analyses are needed. Using patients from the Xinjiang Uygur population as subjects, and the delayed rectifier potassium channel KCNE1 and its associated polymorphism G38S (rs1805127) as the candidate gene, we analyzed the correlation between the G38S polymorphism and AF among the senior Uygur population in Xinjiang Province.
A study of the association between the connexin 40 rs35594137 polymorphism and atrial fibrillation in Xinjiang Chinese Han and Uygur populations
Atrial fibrillation (AF) occurrence has a known genetic component. Many reports have revealed a correlation between gene mutation and AF, involving genes related to ion channels, connexin (Cx), and those within the angiotensin system. In this study, the correlation between the Cx 40 polymorphism (rs35594137) and AF was investigated in patients with AF in the Xinjiang, Turpan, and Kashi regions and in controls. The AF cohort included 122 patients (58 Han and 64 Uygur). The control subjects were recruited according to the 1:1 corresponding method and matched for age and gender.
Analysis of antithrombotic therapy in elderly patients with atrial fibrillation
This study aimed to analyze the impact factors and outcome of antithrombotic therapy in elderly patients over 65 years old that suffered from atrial fibrillation (AF). A total of 256 elderly patients with AF over 65 years old were divided into 3 groups: 65-74 years old (N = 86), 75-84 years old (N = 122), and over 85 years old (N = 48). The clinical characteristics, antithrombotic therapy, and its related impact factors were retrospectively analyzed. Of all patients, 187 received antithrombotic therapy.
KCNE1 112G>A polymorphism and atrial fibrillation risk: a meta-analysis
KCNE1, a membrane protein that spans the membrane once is responsible for modulating potassium channel functions and plays an important role in the etiology of arrhythmia. Emerging evidence indicates that a common polymorphism (112G>A; rs1805127 G>A) in the KCNE1 gene contributes to atrial fibrillation (AF) risk; however, these studies showed inconclusive results. In this meta-analysis, we derived a more precise estimation of the association between the KCNE1 112G>A polymorphism and AF risk.
Relationship between the TaqI B polymorphism of the cholesterol ester transfer protein gene and atrial fibrillation in Han and Kazak populations
The TaqI B polymorphism in the cholesterol ester transfer protein (CETP) (B1 and B2 alleles; rs708272) is associated with changes in enzyme activity and lipid concentrations. The B1 allele of the CETP gene is a known independent risk factor for genetic susceptibility to atrial fibrillation (AF); however, little is known about this polymorphism in the minority groups of Xinjiang, China.
Effect of atorvastatin on left atrial function of patients with paroxysmal atrial fibrillation
The aim of this study was to evaluate the effects of atorvastatin on left atrial (LA) function in paroxysmal atrial fibrillation patients. Fifty-eight paroxysmal atrial fibrillation patients were divided into two groups (treatment and control groups). The echocardiography parameters, including LA active emptying volume (LAAEV), LA active emptying fraction, LA maximum volume, LA total emptying volume, LA total emptying fraction, and LA ejection force (LAEF), were measured before treatment, and then 12 and 18 months after treatment.
Expression of tyrosine hydroxylase and growth-associated protein 43 in aging atrial fibrillation patients of Xinjiang Uygur and Han nationality
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 and Western blot analysis were used to detect gene and protein expressions of TH and GAP43 in atrial tissues of 54 patients with valvular heart disease.
