[Cardiorespiratory system state in renovascular hypertension dynamics after surgical treatment and physical rehabilitation]

The cardio-respiratory system in 50 healthy subjects and 58 patients with renal hypertension was examined using bicycle spiroergometry at rest and after exercise, before and after the reconstructive surgery on renal arteries and following rehabilitational postoperative treatment by physical training. Before surgery the patients showed excessive pressor response to exercises, ECG signs of overload and hypertrophy of the left ventricle and atrium increasing during exercise, decreased oxygenation of the tissues, decreased compensatory and adaptive capacity. After the operation AD at rest decreased, aerobic reserve improved, while chronotropic cardiac reserve aggravated, and pronounced dystonia was noted. After certain physical training decreased pressor responses, significant increase of tolerance to exercise as well as elevation of the aerobic reserve up to that in the trained persons were observed.
