Genetic targets in the management of atrial fibrillation in patients with cardiomyopathy

摘要

Cardiomyopathies are heterogeneous health conditions with the potential for atrial fibrillation. The management of patients with cardiomyopathy accompanied by atrial fibrillation is complicated by the maintenance of sinus rhythm, toxicity, or other complications. There is a lack of information about the reasons for therapy response heterogeneity or therapy failure. Our searching strategy of scientific databases declares a potentially important role of genetics in patients' management. The promising target could be the 4q25 locus and its sequence variants. Molecular-genetic analyses may shed new light on anti-atrial fibrillation therapy in cardiomyopathy patients and help reveal the genetic subtypes of cardiomyopathy patients. In this sense, the purpose of our study is to examine the evidence for genetic variation influencing the efficacy of pharmacological or invasive therapies for atrial fibrillation, especially at the 4q25 locus, in cardiomyopathy patients and declare the importance of detected genetic markers responsible for positive or negative responses to specific anti-atrial fibrillation therapies.
