SUMMARY. Pre- and postoperative exercise tests were performed on 12 children with severe congenital heart disease (CHD) (age, 4-12 years). Oxygen uptake, blood pressure, and heart rate responses to exercise were measured. Exercise test time and the tolerable speed of the treadmill increased significantly after the operation. When pre- and postoperative values were compared, exercise heart rates did not change in most of the children, while delta systolic blood pressure rose significantly. The significant increase in peak oxygen consumption (VO2/Kg) values also revealed that there was an improvement in their exercise capacity after the operation. KEY WORDS: Congenital heart disease - - Exercise tests - - Oxygen consumption
Hemodynamic and cardiopulmonary responses of normal children and children with congenital heart diseases (CHD) to exercise have been previously reported [6, 7, 11, 13, 15, 23]. Many of these assessments were accomplished by bicycle ergometry, either during cardiac catheterization [6, 23] or in exercise laboratories [11-13, 15]. Although the advantages of the treadmill as a mode of exercise have been described [2, 8], it has been difficult to obtain certain physiologic data from children on the treadmill. Recently, exercise data in normal children using a continuous treadmill protocol have been published [4, 20], and clinical exercise testing with treadmill has proved invaluable in assessing children with cardiac problems [16, 21]. To judge the improvement of the impaired exercise capacity in children with CHD after surgery, we compared our preoperative exercise test results to postoperative exercise ones as a preliminary study. Materials and Methods
Subjects We studied 12 children (four girls, eight boys), aged 4-12 years (mean 8.1) with CHD, pre- and postoperatively. Body surface Address offprint requests to: Dr. H. N. Gfirses, Institute of Cardiology, University of Istanbul, Haseki, istanbul, Turkey.
