Association of platelet-to-lymphocyte ratio with silent brain infarcts in patients with paroxysmal atrial fibrillation.

Objectives: In this study, we aimed to evaluate whether the inflammation as measured by increased platelet to lymphocyte ratio (PLR) predispose to silent infarcts in patients with paroxysmal atrial fibrillation (PAF).Methods: The present study investigated a total of 48 new diagnosed patients with PAF who had no signs of stroke. PLR, which was calculated as the ratio of the platelet count to the lymphocyte count, C-reactive protein and erythrocyte sedimentation rate were measured due to evaluate inflammatory state. Magnetic resonance imaging (MRI) was performed to evaluate the presence of silent brain infarcts (SBIs) in patients. We calculated CHA2DS2–VASc scores for stratifying the stroke risk of patients.Results: Among our study population, the mean age was 56.40 ± 8.99; 36 patients were female. The leading vascular risk factor was hypertension (45.8%). SBI was determined in 16 patients (33.3%) on MRI. It was found that a higher PLR is significantly associated with the presence of SBIs in patients with ...
