Abstract
The purpose of this study was to determine if blood pressures (BP) during dynamic exercise (DYN EX) and isometric exercise (ISO EX) in hypertensive adolescents are useful in identifying those destined to have persistent blood pressure elevations. All 62 subjects had pressures above the 95th percentile on three 8th grade exams. Dynamic and isometric stress tests were performed in the 9th grade and resting BP was remeasured on 3 exams in the 10th grade. Students were classified on the basis of their 10th grade BP: I. Normal BP II. Elevated BP on 1 or 2 exams, III. Persistent BP elevations in all 3 exams:
Stepwise regression was used to correlate the BP at rest and during exercise with 10th grade resting BP. Systolic BP during DYN EX and diastolic BP during ISO EX had significant correlations with 10th grade BP, p<.007 and p<.05 respectively. However, comparing exercise pressures with resting pressures, the former accounted for only an additional 5% of the variance of the 10th grade pressures. Therefore, if hypertension is suspected on the basis of three resting pressures doing exercise testing adds little to the accuracy of predicting blood pressure status one year later.
