OBJECTIVE: The aim of this study was to explore the relationships between ADAMTS-13 gene polymorphisms and hypertension-induced atrial fibrillation (AF).

PATIENTS AND METHODS: A total of 200 hypertensive patients without AF (hypertension group) and 200 hypertensive patients with AF (AF group) treated in our hospital were enrolled. Then, peripheral blood was drawn from these subjects enrolled, and the genomic deoxyribonucleic acids (DNAs) were extracted for analysis of ADAMTS-13 gene polymorphism. Next, Reverse Transcription-quantitative Polymerase Chain Reaction (RT-qPCR) was employed to determine the expression of ADAMTS-13 gene, and the correlations of ADAMTS-13 gene polymorphism with ADAMTS-13 gene expression and clinical indicators were analyzed.

RESULTS: Results revealed that there was a difference in the distribution of alleles of ADSMTS-13 rs3094374 (p=0.046) and rs34054981 (p=0.039) between AF group and hypertension group. The frequency of T allele of the locus rs3094374 and that of the locus rs34054981 in ADSMTS-13 gene was higher in AF group than that in hypertension group. The distribution of genotypes of ADSMTS-13 rs28503257 (p=0.047) and rs34054981 (p=0.013) in AF group were different from those in hypertension group, and AF group had lower frequency of GA genotype of ADAMTS-13 rs28503257 and higher frequency of CT genotype of ADAMTS-13 rs34054981 than hypertension group. Besides, a difference was found in the distribution of ADSMTS-13 rs3094374 between AF group and hypertension group in recessive model (p=0.043), and the frequency of TC + CC was higher in the recessive model. Moreover, the distribution of the haplotypes CAT (p=0.012) and CGT (p=0.031) in ADAMTS-13 gene showed a difference between AF group and hypertension group. The linkage disequilibrium of the loci rs3094374 and rs28503257 in ADAMTS-13 gene was relatively great (D’=0.293). In addition, the polymorphism of the locus rs34054981 in ADAMTS-13 gene had an association with ADAMTS-13 gene expression (p<0.05). The expression of ADAMTS-13 gene was lower in patients carrying genotype TT in AF group. Furthermore, the ADAMTS-13 rs3094374 polymorphism was related to international normalized ratio (INR) (p=0.034), and the ADAMTS-13 rs28503257 polymorphism was correlated with the levels of brain natriuretic peptide (BNP) (p=0.047) and D-dimer (p=0.033).

CONCLUSIONS: ADAMTS-13 gene polymorphism is correlated with the susceptibility and procession of hypertension-induced AF.
