缺血性中风(IS)是中风的最常见类型,占中风的三分之二。40%以上的 IS 患者有血液流变学异常(包括全血和血浆粘度升高、红细胞压积升高、红细胞和血小板聚集增加、红细胞变形力降低及血浆纤维蛋白原浓度升高等)。一、全血粘度决定全血粘度的因素有血红细胞浓度(HCT)、红细胞聚集(RCA)、红细胞变形(RCD)以及血浆蛋白,尤以纤维蛋白原浓度最为重要。1.红细胞方面:Swank(1959)最早发现 IS 患者的全血及血 Ischemic stroke (IS) is the most common type of stroke, accounting for two-thirds of strokes. Over 40% of patients with IS have abnormalities in blood rheology, including increased whole blood and plasma viscosity, elevated hematocrit, increased accumulation of red blood cells and platelets, reduced erythrocyte deformability, and elevated plasma fibrinogen concentrations. First, the whole blood viscosity determine the factors of whole blood viscosity Red blood cell concentration (HCT), red blood cell aggregation (RCA), red blood cell degeneration (RCD) and plasma proteins, especially fibrinogen concentration is the most important. 1. Red blood cells: Swank (1959) was the first to find IS patients with whole blood and blood
