Results (6 mo. to 18.5 yr) after aortal coarction surgery were evaluated in 145 patients [PT]. PT (42) were subjected to spiroveloergometry [SVE] which revealed 35 PT with good or satisfactory and 7 with unsatisfactory results. In the latter, correction of the defect was adequate, but arterial pressure [AP] increased by 15% although it did not exceed 160 mm Hg. Normotonic [NT], dystonic [DT], hypertonic [HT] and asthenic types of AP were observed. Increased blood circulation in PT with asthenic AP reaction was due to increased heart rate and indicated decreased functional capacity of the cardiovascular system. No direct relationship was observed between clinical effects of surgery and type of AP reaction to SVE loading, although the NT type was observed more frequently with good and satisfactory results. PT with NT or DT types of reaction in whom the SVE index was unchanged or slightly changed, retained their working capacity and did not require rehabilitation. Limited physical loading and treatment similar to that for neurocirculatory dystonia (AP control, and hypotensive and sedative drugs) were recommended for PT with HT or asthenic reaction. PT with pronounced changes of the SVE index and those with AP increase to 180-200 mm Hg, were permitted light physical work or mental work with litle nervous stress. The reasons for unsatisfactory results were the presence of systemic HT, residual stenosis, recoarctation and occurrence of pseudoaneurysms. Hospital observation was recommended for all PT with AC correction for early detection of complications and early treatment.
