title: [Clinical aspects of hypertensive crises].
abstract: Hypertensive crises were studied in 80 patients. In severe cases the ECG provided evidence of systolic overloading of the left ventricle with intensification of coronary circulation and development of acute myocardial ischemia. Phase analysis showed prolongation of the mechanical systole with increase of the myocardial index. In more complicated cases there was a more evident hypodynamic syndrome with marked myocardial insufficiency. Hemodynamic disturbance were marked by a sharply increased peripheral resistance with a heterogenous reaction of the cardiac output. Blood supply to the cerebral tissue reduced sharply with an increase in the resistance of cerebral vessels. Renin activity was directly related to the severity of the crisis. A sharp onset of cerebral and cardiac ischemia was marked by changes in the antigen albumin. Timely diagnosis and differentiated treatment made it possible to avoid vascular complications in hypertensive crisis.
