Kulkšnies – žasto indekso, vidutinio trombocitų tūrio ir leukocitų kiekio kraujyje sąsajos su lėtiniu prieširdžių virpėjimu.

The aim: To determine the relation of ankle – brachial index (ABI), mean platelet volume (MPV) and white blood cell (WBC) count to permanent atrial fibrillation (AF). The objectives: 1. To compare MPV between patients with and without permanent AF and to determine its relation to CHA2DS2-VASc score. 2. To determine the relation of ABI and MPV to permanent AF. 3. To compare WBC count between patients with and without permanent AF. 4. To compare MPV between patients with and without peripheral artery disease (PAD). 5. To evaluate the sensitivity and specificity of MPV in patients with PAD. Methods: A total of 180 patients were enrolled into the study. Participants were divided into two groups: patients with permanent AF (95 patients) and patients in sinus rhythm (SR) (85 patients). ABI was measured, 5-MHz Doppler was used to measure the systolic arterial blood pressure in the lower extremities. PAD was diagnosed when ABI was 8,55 fl and in 35,9% of patients without these risk factors (p=0,001). Patients with and without PAD were compared and MPV was found to be significantly higher in patients with PAD (p8,55 fl than in patients with ABI>0,9 and MPV
