[The pathology of catecholamine metabolism in cerebrovascular diseases].

Blood catecholamines were investigated with high-performance liquid chromatography and electrochemical detection in 95 patients with cerebrovascular affections. On day 1-3 since ischemic apoplexy blood norepinephrine and dopamine levels increased significantly. This is possibly due to their active release from neurons in brain tissue ischemia. High blood catecholamines are thought an unfavourable factor aggravating the disease and responsible for cardiac sequelae. Ways of cerebral tissue protection in case of ischemia are suggested.
