Management of Atrial Fibrillation

Вackground. It is known that 5–21% of patients with acute coronary syndrome (ACS) develop atrial fibrillation (AF), which entails an increased risk of recurrence of myocardial infarction, heart failure, and increased mortality. The genetic predisposition to AF has been actively studied in recent years, but the data on the association of certain single nucleotide polymorphisms (SNPs) in the development of AF are contradictory, which determines the relevance of this study. Purpose of the study. To study five SNPs for associations with the development of non-valvular atrial fibrillation in patients with acute coronary syndrome Patient Characterization and Research Methods. The study included female and male patients not younger than 18 years old with ACS and AF (n = 133) and ACS without AF (n = 133) ACS was diagnosed according to the criteria of the European Society of Cardiology (2015; 2017). The study was approved by the Ethics Committee (Minutes No. 102 dated November 24, 2017). The observation period was 12 months. In addition to the standard examination, all patients underwent a SNP study: rs6795970 (Scn10a), rs2200733 (4th stage), rs11556924 (ZC3HC1), rs599839 (PSRC1), rs10824026 (10th stage). Statistical analysis was performed using Statistica 12.1 StatSoft. Results. The results of the rs599839 study showed that the GG genotype was significantly less common in the ACS + AF group compared to the ACS group without AF (OR 0.11 CI 95% 0.01; 0.86 p = 0.0163). A reliable connection was lost when divided by sex and by age (older and younger than 55). Allele G rs599839 significantly correlates with AF (p = 0.0043; OR 1.56). The T allele rs11556924 is highly reliably associated with a predisposition to atrial fibrillation (p = 0.0043; OR 1.93). Genotype GG rs10824026 is conditionally protective in terms of the risk of AF in patients with ACS. For rs6795970 (p = 0.290) and rs2200733 (p = 0.30), there were no statistically significant differences between the study groups. Conclusion. The study verified the association of rs6795970 (Scn10a), rs2200733, rs11556924, rs599839, rs10824026 with AF associated with ACS. The genotypes GG rs599839 and GG rs10824026 were found to be conditionally protective in relation to the risk of AF in patients with ACS.
