Sažetak:
Background. It appears that atrial fibrillation (AF) may have genetic determinants. Estrogen regulates expression of many genes through estrogen receptor  (gene ESR1) and β (ESR2). ESR1 polymorphisms alter expression of different genes, including those of eNOS and L-type Ca2+ channel gene. The long allele of ESR1 variant has been associated with increased cardiovascular risk profile. Association of ESR1 gene polymorphism with AF in patients without gross structural cardiac abnormality. Those patients were selected to avoid the smothering of inheritance by dominant exogenous factors. Methods. We analyzed TA polymorphism of long-L ( ≥19 TA repeats ; 178-194 bp) and short-S (<19 TA repeats ; 160-176 bp) alleles in regulatory region of estrogen receptor ESR1 by PCR and capillary electrophoresis. The study included 40 patients (23 males, aged 50 ±14.8 and 17 females aged 57 ± 14.2 years) with atrial fibrillation and 35 healthy controls. Only patients without major structural heart disease were included, as inferred from clinical examination, ECG and echocardiography. Results. Long allele of ESR1 gene was more frequent in AF than in control group (52.5 vs 42.9%). ESR1 long allele homozygotes were strikingly more frequent in the AF than in control group, reaching statistical significance in males (p>0.02). Logistic regression analysis revealed male gender and LL allele as the significant risk factors for AF. Conclusions. Functional activity of estrogen receptors may be more critical in males than in females with abundance of circulating estrogen. These preliminary results point at the need for further research of ESR1 role in AF.
