Prevalence of stroke risks and anticoagulation activity were not different between groups D and A. The alteration of inflammatory markers in a week in the group A showed similar trend to those in the group P. The group D presented relatively lower amount of high-sensitive C-reactive protein and higher amount of pentraxin-3 compared with groups A and P. While 88.9% of group P patients showed decreased platelet aggregation activity with adenosine diphosphate, 55.6% of group D and 40.0% of group A presented the inhibition of platelet aggregation activity. This evidence concerns the gene PTX3 and Stroke.
