[Changes in cardio- and hemodynamics in vasorenal hypertension after surgical treatment]

Cardio- and hemodynamics were studied in 21 patients with vasorenal hypertension after surgical correction of the renal blood flow. Reduction of arterial pressure due to marked decrease of total peripheral resistance was noted. In the early postoperative period the minute circulation volume increased because of tachycardia, in the late periods it increased due to an increase in the systolic volume with concomitant decrease in the rate of cardiac contractions. A tendency towards a hyperkinetic type of circulation was revealed in the late postoperative period.
