Peripheral Blood Lipidomic and Ceramide Profiles in Atrial Fibrillation (LIPID-AF)
Association of Peripheral Blood Lipidomic and Ceramide Profiles With Atrial Fibrillation: A Prospective Multi-Cohort Observational Study
Обзор исследования

Условия
Подробное описание
Atrial fibrillation is a common cardiac arrhythmia associated with metabolic disturbance and cardiac remodeling. Lipid metabolism, including sphingolipid and ceramide metabolism, may be involved in the pathophysiology of atrial fibrillation. Further clinical evidence is needed to clarify whether peripheral blood lipidomic and ceramide profiles are associated with atrial fibrillation.
This study is designed as a prospective multi-cohort observational study. Participants will be classified into an atrial fibrillation group or a control group according to Holter monitoring and clinical information. Control participants will be patients with other cardiovascular diseases without documented atrial fibrillation. Peripheral blood samples will be collected for lipidomic or targeted ceramide analysis.
Untargeted lipidomic profiling will be used to evaluate peripheral blood lipidomic features in one cohort, and targeted ceramide assays will be used to evaluate peripheral blood ceramide profiles in another cohort. The overall purpose of this study is to explore the relationship between peripheral blood lipidomic and ceramide profiles and atrial fibrillation.
