EXERCISE TOLERANCE AND BEHAVIOR OF BLOOD-PRESSURE IN CHILDREN AND ADOLESCENTS AFTER RENAL-TRANSPLANT

Objective, The purpose of the study was to evaluate the exercise toler ance and the behaviour of blood pressure during a maximal exercise tes ting on treadmill for a group of patients with renal transplant carrie d out at least 6 months earlier, Experimental design, setting and pati ents. In a retrospective study, nineteen patients were examined in our laboratory: 13 boys and 6 girls, mean age 15.8 years (range 10.5 - 22 ), Interventions. All patients were given a clinical examination, an E CG at rest, a maximal exercise testing on treadmill (Bruce protocol), a mono - 2D echo, a lung function test and 24-hour Holter monitoring, The results of the exercise test H-ere compared with those of two cont rol groups of same age and body surface area, Results, The clinical ex amination of their cardiovascular apparatus gave normal results, The e cho revealed anatomical and heart function anomalies related to the or iginal disease, Exercise testing on treadmill showed a reduction in ex ercise tolerance (p<0.001) and the maximal heart rate showed a statist ically significant difference (p<0.001) in comparison to control group s, Maximal systolic blood pressure was higher than in patients with sa me body surface area (p<0.001) and higher than in peers (p=0.133), Con clusions. In view of this hypertensive response, strenuous physical ac tivity should be undertaken with caution and indeed submaximal aerobic activity is more suitable for this population of patients.
