Table 2 Presence of left atrial stasis on transesophageal echocardiogram and sub-analysis according to mean platelet volume

From: Mean platelet volume is associated with the presence of left atrial stasis in patients with non-valvular atrial fibrillation

  Overall MPV ≤ 9.4 fL MPV > 9.4 fL P
  (n = 427) (n = 245) (n = 182)  
LAAT 12.2% (52) 9.0% (22) 16.5% (30) 0.019
DSEC 29.7% (127) 23.7% (58) 37.9% (69) 0.001
LFV 15.3% (54/354)a 9.1% (19/208) 24.0% (35/146) <0.001
LA ABN 34.2% (146) 27.3% (67) 43.4% (79) 0.001
  1. Legend: MPV Mean platelet volume, LAAT Left atrial appendage thrombi, DSEC Dense spontaneous echo contrast, LFV Low flow velocities in the left atrial appendage, LA ABN Left atrial abnormality.
  2. a only 354 subjects had assessment of left atrial appendage flow velocities due to technical or procedural reasons (see Discussion).
