Differences in anticoagulation treatment between patients with and without LAT detected by TOE performed for electrical cardioversion of AF
| LAT found (n = 91) | No LAT found (n = 1022) | P-value | |
|---|---|---|---|
| Anticoagulation, n (%) | |||
| Experienced | 69 (75.8) | 745 (72.9) | 0.6221 |
| Naïve | 22 (24.2) | 277 (27.1) | |
| Prior 30-day anticoagulation | 55 (60.4) | 514 (50.3) | 0.0795 |
| VKA, n (%) | 43 (47.3) | 340 (33.3) | 0.0081 |
| NOAC, n (%) | 14 (15.4) | 183 (17.9) | 0.6671 |
| INR at enrolmenta | |||
| Mean ± SD | 1.6 ± 0.7 | 1.5 ± 0.6 | 0.3381 |
| ≥2, n (%) | 22 (27.2) | 213 (23.5) | 0.4955 |
Suboptimal anticoagulation was defined as missing ≥1 dose of NOAC or enoxaparin-warfarin with INR <2.
a
Denominators are the number of patients who took VKAs.
AF, atrial fibrillation; INR, international normalized ratio; LAT, left atrium thrombi; NOAC, non-vitamin K antagonist oral anticoagulant; SD, standard deviation; TOE, transoesophageal echocardiography; VKA, vitamin K antagonist.
