5 Conclusion
Our study found that left atrial phasic function was significantly
impaired in patients with AF, and patients with persistent AF were more
severely damaged than those with paroxysmal AF. The combination of
RT-3DE and 2D-STI can more comprehensively evaluate left atrial
structure and function. EAT thickness was significantly negatively
correlated with left atrial reservoir function, booster function and
conduit function. EAT thickness measured by TTE can effectively reflect
the change trend of left atrial structure and function in patients with
AF, thereby providing a certain reference for clinical
practice.
