Mean Platelet Volume, C-Reactive Protein, and Prognosis in Patients with Acute Ischemic Stroke Following Intravenous Thrombolytic Treatment.

Abstract

BackgroundThe aim of this study was to investigate the association between mean platelet volume (MPV), C-reactive protein (CRP), and prognosis in patients with acute ischemic stroke (AIS) following intravenous (IV) thrombolytic treatment.Material/MethodsA retrospective clinical study included 129 patients within 4.5 hours from the onset of AIS, who received IV thrombolytic treatment. Clinical data were retrieved from electronic medical records. MPV, CRP, and National Institutes of Health (NIH) Stroke Scale and the modified Rankin Scale (MRS) scores for physical disability were recorded.ResultsOf the 129 patients, 65.9% were men, and more than half received IV thrombolytic treatment within between 3–4.5 hours. The NIH Stroke Scale scores at 24 hours and at three months after hospital admission were compared with the NIH Stroke Scale scores on hospital admission. A significant correlation was found between the MPV values at 24 hours (r=0.221; p=0.012) and at three months after hospital admission (r=196; p=0.026). There was a significant correlation between CRP values at 24 hours (r=0.224; p=0.021), the difference in NIH Stroke Scale score between 24 hours and three months (r=0.249; p=0.005), and the MPV score at three months (r=0.186; p=0.035).ConclusionsMPV and CRP values were significantly associated with improvement in the NIH Stroke Scale and MRS scores in AIS when patients were treated with IV thrombolytic therapy within 4.5 hours of the onset of symptoms.
