New stroke prognostic factors

Background Understanding ischemic stroke pathogenesis helps in prevention, prognosis, and treatment. Stroke is greatly related to inflammation and thrombo-genesis as inflammatory cells (as neutrophils-lymphocytes) and thrombo-genic agents as von Willebrand factor antigen (VWF: Ag) and epicardial fat. Objectives of the study Evaluation of epicardial fat thickness (EFT), neutrophil/lymphocytic ratio (NLR), and (VWF: Ag) levels as predisposing and prognostic factors of ischemic stroke. Patients and methods Sixty acute ischemic stroke patients were subjected to clinical assessment (Oxford stroke sheet), National Institute Health Stroke Scale: NIHSS), Modified Rankin Scale (MRS), NLR and VWF: Ag levels, transthoracic echo, duplex on carotid and vertebro-basilar arteries, and brain computed tomography (CT). Thirty-five healthy controls matched for age and sex were subjected to the same steps except NIHSS and MRS. Results EFT, NLR, and VWF among patients were significantly higher than control group. NLR ≥ 2 and VWF: Ag were significant risk factors among stroke patients with VWF: Ag had the higher risk than NLR ≥ 2. NLR was a high valid prognostic marker in predicting stroke outcome (MRS) with (optimal cutoff value 2.05) for prediction of primary unfavorable outcome. There was no statistical significance between (MRS) and EFT or VWF: Ag level. Conclusion EFT represents inexpensive and readily available clinical marker that may be useful in estimating risk of ischemic stroke. NLR is non-expensive easy marker for predicting stroke severity and primary unfavorable outcome. High VWF level increases ischemic stroke risk.
