OBJECTIVE: The aim: To identify clinical and hemodynamic factors, associated with left atrial spontaneous echo contrast (LASEC) (LASEC in general, and the dense LASEC), in non-valvular persistent atrial fibrillation (AF) patients with the duration of AF episode ≥90 days.
PATIENTS AND METHODS: Materials and methods: The cross-sectional study consecutively enrolled 115 persistent AF patients with the duration of its episode ≥90 days (82 (71,3 %) males; mean age 59 ± 11 years). Transthoracic (TEE) and transesophageal echocardiography (TEE) were performed. LASEC (by TEE) was observed in 79 (68,7 %) patients. The dense (moder¬ate-to-severe) LASEC was detected in 23 (20,0 %) cases.
RESULTS: Results: Heart failure (HF) stage C (OR 2,09 (95 % CI 1,24-3,53); p=0,006), lower TEE-derived left atrial appendage (LAA) flow velocity (FV) (OR 0,94 (95 % CI 0,91-0,98); p=0,003), and the presence of TTE-derived pulmonary hypertension (PH), appeared to be strongly associated with LASEC (AUC for logistic regression model: 0,83 [95 % СI 0,75- 0,89]). The presence of diabetes mellitus type 2 (DM) (OR 2,34 (95 % CI 1,13-4,86); p=0,027), along with lower LAA FV (OR 0,83 (95 % CI 0,76-0,91); p<0,001), were strongly associated with dense LASEC (AUC: 0,89 [95 % CI 0,82-0,94]).
CONCLUSION: Conclusions: The TEE-derived LASEC in patients with long term episodes (≥90 days) of persistent AF was strongly associated with HF stage C and TTE-derived PH, and with lower TEE-derived LAA FV. The presence of DM, in addition to lower LAA FV, was related to dense LASEC.
