We studied 71 patients with hypertensive disease and sinus rhythm on the ECG without clinical signs of heart failure in the acute stage of ischemic stroke compared to 36 patients with arterial hypertension without complications. A retrospective analysis including 91 patients with uncomplicated arterial hypertension examined previously (3-8 years ago) using the same protocol was carried out. The results of this examination were extracted from our database. The greater hypertrophy of the left ventricular, signs of diastolic dysfunction of the both ventricles and a statistically significant decrease in the blood flow through the right auricle were identified in the patients with the acute cerebral blood flow disturbances. The retrospective analysis of patients with arterial hypertension demonstrated the predictive value of the decrease in the peak velocity of transmitral diastolic flow in the phase of rapid filling Ve in the development of cerebral vascular complications of the disease and lethal outcome.
