[Comparative characteristics of clinical and pathogenetic features of first and recurrent cerebral stroke].

Based on the data of clinical and laboratory-instrumental study of 81 patients with recurrent stroke, including 63 cases after the first ischemic stroke and 18 cases after the first hemorrhagic stroke, we compared clinical-pathogenetic correlations between first and recurrent strokes. A trend towards the localization of a focus of secondary stroke in the same hemisphere in case of the similar to the first stroke clinical form and in the other hemisphere in case of changing the clinical form (ischemic to hemorrhagic and vice versa) was found. Among the pathogenetic types of ischemic stroke, lacunar and hemoreologic types were most stable in the secondary stroke compared to the first one. In other variants, the pathogenesis of recurrent stroke changed more often. The authors concluded that further research in this direction would help to solve issues in prediction of secondary stroke and improvement of secondary prophylaxis.
