Inclusion criteria
* ≥2 paroxysmal (electrocardiographic documentation of at least 1) AF episodes lasting ≥1 hour in duration: (that terminate spontaneously within 7 days or cardioversion is performed within 48h of AF onset): or * electrocardiographic documentation of 1 persistent AF episode: (sustained for ≥7 days or cardioversion is performed more than 48h after AF onset): or * electrocardiographic documentation of 1 longstanding persistent AF episode: (continuous AF of duration \>1 year).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| endovascular function results | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| predictive effect of endovascular function on recurrence of AF | Up to 1 year | We will do the multi-logistic analysis of the recurrence of AF. |
