The aim of this study was to investigate the behavior of blood pressure during exercise testing and 24-hour ambulatory blood pressure monitoring, and the correlation between maximal and mean 24-hour systolic blood pressure in children after repair of aortic coarctation. We studied 27 patients (18 males and 9 females, mean age 9.9 years): 18 had subclavian flap, 6 patch angioplasty and 3 end-to-end anastomosis. Mean follow-up was 68 months; no patient was taking antihypertensive therapy. The control group consisted of 27 age and gender' matched children. All subjects performed exercise testing on treadmill (Bruce); arm/leg systolic blood pressure gradient both before and after exercise in patients only. Patients had 24-hour ambulatory blood pressure monitoring. The duration time of exercise and maximal heart rate were significantly lower in patients than in controls; maximal systolic blood pressure was significantly higher; the arm/leg gradient after exercise was higher than gradient at rest. The positive correlation between mean 24-hour and maximal systolic blood pressure was significant. Exercise testing and ambulatory blood pressure monitoring are useful tools during follow-up, to detect abnormalities of blood pressure in children after coarctation repair, and to suggest the best sports activity and possible antihypertensive treatment.
