What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
endovascular function results
Time Frame: Up to 24 weeks.
The method to assess the endovascular function is PAT. The index is Reactive hyperemia index (RHI). RHI between patients and control will be compared.
Up to 24 weeks.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
predictive effect of endovascular function on recurrence of AF
Time Frame: Up to 1 year
We will do the multi-logistic analysis of the recurrence of AF.
Up to 1 year
