Objective: Physiologic studies have shown that atrium has an active role in venous blood return from lower extremity.
In this context we investigated the association between AF and chronic venous disease (CVD).
Methods: In this observational study we included 392 AF patients which were divided into two groups (chronic AF, 218
(56%)) and non-chronic. AF, 174 (44%)). These two groups were compared in terms of CVD after matching conventional
risk factors for CVD.
Results: CEAP classification was different between chronic and non-chronic patients (C0–C2: 72% vs 47%; C3–C6: 28%
vs 53% <0.001). Chronic AF patients had also higher rate of venous reflux on Doppler ultrasound (38% vs 16%
P<0.05). There was a correlation between AF duration, right atrial volume index and CEAP classification respectively
(rho:0.314 p<0.001), (rho:0.258, p<0.001).
Conclusion: Prevalence of CVD is higher in patients with chronic AF. In addition, atrial volume is directly correlated
with CVD.
