109 exercise blood pressure reseonsea predictor of severity in aortic stenosis

ABSTRACT To assess whether the increase(I) in systolic blood pressure (SBP) with exercise may predict the severity of aortic stenosis (AS), we performed treadmill exercise tests on 116

healthy children and 40 with AS. The Ellestad or Bruce protocol was used in all subjects. A maximal test was determined by heart rates 180 or extreme fatigue. SBP was obtained at rest and

within 15 seconds of termination of exercise. There was no relation between SBPI and either sex or age in either group. The AS patients had a lower SBPI, 30.6±14.9 mmHg, than the control

group, 43.1±18.7 mmHg (p<0.001). SBPI values of <35 or ≥35 mmHg separated patients with left ventricle to aorta gradients above and below 50: If a SBPI value of ≥35 is obtained, there

is a low probability (7%) of a gradient > 50. Of 9 AS patients with gradients > 50 mmHg, 8 had SBPI < 35. Exercise SBPI appears to be a valuable part of the total non-invasive

assessment of children with AS. While a low value is not always predictive of a high gradient, a high value (≥35) suggests AS not of sufficient severity to routinely warrent catheterization.
