Our study also examined age, comorbidities (hypertension, diabetes mellitus, atrial fibrillation, smoking), NIHSS scores, site of occlusion, surgery-related data (type of treatment, procedure duration time and onset-recanalization time) and laboratory markers (lymphocytes, neutrophils, monocytes, CRP, NLR, MHR, LMR, LCR, LHR), yielding that the NIHSS score, NLR, procedure duration time were higher in the FR group than in the control group. The gene discussed is CRP; the disease is atrial fibrillation.
