[Importance of parameters of central hemodynamics in examining working capacity of patients with renovascular hypertension]. / Znachenie pokazatelei tsentral'noi gemodinamiki dlia ékpertizy trudosposobnosti bol'nykh vasorenal'noi gipertenziei.

Cardiovascular system parameters were measured in 80 patients with renovascular hypertension using resting and bicycle exercise readings of tetrapolar chest rheography. The findings were indicative of various defects in central hemodynamics. Signs of subclinical initial stage of cardiac insufficiency were revealed in 57.5% of cases. Cardiovascular reserves were reduced in patients operated on fading with increasing duration of the disease. Labor prognosis appeared more favorable in operated on patients with good hypotensive effect of the surgery.

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.
