Table 1 Study population baseline characteristics

From: Which method of left atrium size quantification is the most accurate to recognize thromboembolic risk in patients with non-valvular atrial fibrillation?

Baseline characteristics (n = 500)

Estimated current AF episode duration Laboratorial evaluation
≤ 48 hours 7% (35) Haemoglobin (g/dL) 13.2 ± 1.8
< 1 week 19.6% (98) Platelets (103/μL) 219.7 ± 85.5

> 6 months 35.8% (179) INR ≥ 2.0 20.8% (104)
> 1 year 26.8% (134) GFR (mL/min/1.73 m2) 62.4 ± 33.0
  1. Legend: GFR – glomerular filtration rate; ICD - implantable cardioverter defibrillator; INR – international normalized ratio; LV – left ventricle; TIA – transient ischaemic attack.
  2. aVascular disease is defined as having at least one of the following: myocardial infarctions, peripheral artery disease, and complex aortic plaque.
