Non-paroxysmal atrial fibrillation (OR 3.766) and increased left atrial diameter (OR 1.171) were independent risk factors for left atrial thrombus or spontaneous echo contrast in patients with non-valvular atrial fibrillation and low CHA2DS2-VASc scores.

Are left atrial enlargement and non-paroxysmal atrial fibrillation risk factors for left atrial thrombus or spontaneous Echo contrast in patients with atrial fibrillation and low CHA2DS2-VASc scores?
In patients with non-valvular atrial fibrillation and low CHA2DS2-VASc scores, left atrial enlargement and non-paroxysmal AF are associated with the presence of left atrial thrombus or spontaneous echo contrast.
Effect estimate: OR 3.766 (95% CI 1.282-11.061)
p-value: p=0.016
OBJECTIVE: -VASc scores, which remain undefined. METHODS: -VASc score (0 or 1; 1 point for female sex) out of 1346 consecutive patients with non-valvular AF who underwent transesophageal echocardiography (TEE) at Guangdong Cardiovascular Institute between January 2013 and December 2015. RESULTS: < 0.0001, 95% CI: 0.793-0.914). CONCLUSION: -VASc score, the presence of LAT or SEC was associated with left atrial enlargement, which had moderate predictive value, and non-paroxysmal AF.
Lin et al. (Sun,) conducted a observational in Non-valvular atrial fibrillation with low CHA2DS2-VASc score (n=705). Non-paroxysmal atrial fibrillation vs. Paroxysmal atrial fibrillation was evaluated on Left atrial thrombus (LAT) or spontaneous echo contrast (SEC) (OR 3.766, 95% CI 1.282-11.061, p=0.016). Non-paroxysmal atrial fibrillation (OR 3.766) and increased left atrial diameter (OR 1.171) were independent risk factors for left atrial thrombus or spontaneous echo contrast in patients with non-valvular atrial fibrillation and low CHA2DS2-VASc scores.
