Even if the well-known predisposing factors play an essential role in the realization of cerebrovascular accidents, in these last years the possible importance of the hemoreologic parameters is still a topic under discussion. The authors found a significant increase of the considered hemoreologic parameters (HT, Hb, RBC) in the patients hospitalized for cerebrovascular accidents compared to controls, without differences for gender, even if this increase remained into the limits of normal range. Conversely, no significant differences were found concerning the considered metabolic parameters.
