[Cardiac and hemodynamic disorders in the pathogenesis of the initial manifestations of cerebrovascular pathology].

Initial manifestations of cerebrovascular pathology (CVP) in the presence of arterial hypertension (n-26) and atherosclerosis (n-428) were combined with various cardiovascular disorders ranging from cardialgia to coronary heart disease in 67.4% of the patients. Cardial disturbances were expressed as an atypical pain syndrome in 47% and as angina of effort and postinfarction cardiosclerosis in 23.2% of the patients. Electrocardiographic changes were elicited in 52.6-62% of the patients. Bicycle ergometry revealed a decrease in all parameters of tolerance to physical exercise. Disorders of the general and cerebral hemodynamics were more pronounced in atherosclerotic patients; at the first stages of cerebral pathology they predominantly presented the normokinetic type of the hemodynamics (40.6%) while its more marked forms were associated with the hypokinetic type of the circulation (52). The early diagnosis of cardial and hemodynamic disorders is necessary for the presention of acute disturbances of the cerebral circulation.
