The Genetic Basis for Atrial Fibrillation

NCT ID: NCT03491202

Last Updated: 2018-06-11

Basic Information

• Recruitment Status: UNKNOWN
• Total Enrollment: 600 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2017-05-25
• Study Completion Date: 2022-05-31

Brief Summary

Atrial fibrillation (AF) is reaching epidemic proportions in the aging U.S. and European populations, but the mechanisms of increased susceptibility to atrial fibrillation are still unknown. In this study, we look to further examine genetic and medical co-morbidity influence of atrial fibrillation duration and response to medications. In Specific Aim 1, we propose the creation of a Veterans Affairs AF Biorepository (VAAFBio), which is a resource that will collect and store clinical, demographic, blood and DNA samples from patients with atrial fibrillation to aide this study and future studies of this type in the VA population. In Specific Aim 2, examine common genetic polymorphisms in veteran patients with atrial fibrillation and examine gene-environment interactions with risk factors for atrial fibrillation.

Detailed Description

Atrial fibrillation (AF) is reaching epidemic proportions in the aging U.S. and European populations, but the mechanisms of increased susceptibility to atrial fibrillation are still unknown. In this study, the investigators look to further examine genetic and medical co-morbidity influence of atrial fibrillation duration and response to medications. In Specific Aim 1, the investigators propose the creation of a Veterans Affairs AF Biorepository (VAAFBio), which is a resource that will collect and store clinical, demographic, blood and DNA samples from patients with atrial fibrillation to aide this study and future studies of this type in the VA population. In Specific Aim 2, the investigators will examine common genetic polymorphisms in veteran patients with atrial fibrillation and examine gene-environment interactions with risk factors for atrial fibrillation.

Patients will be identified through the VA inpatient and outpatient clinic, and will be approached for inclusion in the study. The target enrollment for the research and biorepository is 600 participants. A detailed family history, medical background, study questionnaires and a blood sample will then be obtained by the principal investigator or a research coordinator, following written informed consent under a protocol approved by the Jesse Brown VA Institutional Review Board. Once enough samples are collected, coded DNA samples will be sent out to analyze for linkage to known/candidate loci for AF.
