Abstract

Atrial fibrillation (AF) is the most common cardiac arrhythmia. High mobility group box 1 (HMGB1) has been demonstrated to be involved in AF, but the genetic relationship between them is not clear yet. Here, we investigated the genetic association between functional variants in HMGB1 and AF in a Chinese Han population. Two common variants (the promoter one rs1045411T/C and the 3'UTR one rs1412125C/T) in HMGB1 were selected and genotyped in 576 AF patients and 869 control subjects. Traditional risk factors, such as age, gender, the history of smoking, hypertension and diabetes mellitus, were adjusted as covariates using a logistic regression analysis (SPSS, v.21.0). The haplotypic analysis was performed using SPSS (v.21.0, Inc., Chicago, IL, USA). Under the allelic association analysis, neither rs1045411T/C nor rs1412125C/T was associated with AF with all P values >0.05; under the genotypic association analysis, the 3'UTR variant rs1045411T showed a marginally significant association with AF under the recessive model (Padj=0.056, OR =0.42; 95% CI: 0.17-1.02). When divided the studied population by gender, we still found no significant association results between the selected variants and AF with P values more than 0.05; however,...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
