Background: The mechanism of progressive neurological deficit in patients with recent small subcortical infarcts has not yet been clarified. Inflammatory biomarkers and the use of cilostazol may be associated with this phenomenon. Methods: Between May 2013 and April 2014, we evaluated consecutive first-ever patients with stroke due to recent small subcortical infarcts within 48 hours of onset. We divided patients into 2 groups according to the use of antiplatelet agents (cilostazol with or without aspirin versus aspirin alone). Plasma biomarkers such as matrix metalloproteinase-9, interleukin-6, high sensitive C-reactive protein, and amyloid beta precursor protein (APP770, indicating endothelial dysfunction) were measured twice: (1) within 24 hours; and (2) 1 week after their admission. Multivariable logistic regression analyses were performed to identify the variables independently associated with progressive neurological deficit and poor functional outcome. Results: We analyzed 41 patients (male: 63.4%, mean age: 70.8 years). Most of the patients (90%) who were treated with cilostazol were concomitantly treated with aspirin. Matrix metalloproteinase-9 and high sensitive C-reactive protein were higher in patients with progressive neurological deficit compared with those without. APP770 were more likely to be decreased in cilostazol group compared with aspirin group. Multivariable analyses show that traditional risk factors such as age and National Institutes of Health Stroke Scale scores were independently associated with both progressive neurological deficit and poor functional outcome. Conclusions: Inflammatory biomarkers may be associated with progressive neurological deficit. Early initiation of cilostazol may decrease the levels of plasma biomarkers.
