[The mechanisms of the adaptation of the cardiovascular system to physical loading in patients with arterial hypertension in the late periods following the hemodynamically adequate correction of aortic coarctation].

Arterial hypertension was detected in 40 (59.7%) of 67 patients operated on for aortic coarctation. The patients' age ranged from 15 to 35 years. The hypertensives whose physical working capacity corresponded to that of healthy persons showed no increase in stroke index and an inadequate rise of cardiac index with preserved left ventricular in tropic function and high specific peripheral resistance developed due to irreversible structural changes in the vascular bed. Hence, an elevation in blood pressure is due to high peripheral resistance. To make recommendations on exercises for patients undergoing aortic coarctation resection bicycle ergometric test should be performed along with studies of hemodynamic parameters.
