摘要：
Aims: To determine the safety of exercise testing ( ET) in patients with moderate or severe asymptomatic aortic stenosis (AAS) and its accuracy to predict the need for surgery and mortality. Methods: 106 consecutive patients with AAS performed a maximal ET. Results: Follow-up [10.7 (4.9-19.4) months ( percentile 25-75)] was completed in 102 patients(96.2%), 63.9 years (+/- 15.1), 65 (61.3%) male, peak gradient 82.8 mm Hg (+/- 25.4), mean gradient 50.5 mm Hg (+/- 16.6), valve area 0.67 cm(2) (+/- 0.16); 67 patients (65.7%) had abnormal ET. Among the 35 patients with normal ET, there were no deaths and 10 aortic valve replacements (AVR) (28.5%) were performed. Among the 67 patients with abnormal ET, 37 (55.2%) had events (35 AVR and 2 died) (p < 0.0001). There were no complications with ET. Conclusion: ET may be performed safely in patients with AAS. ET gives additional information to an AVR decision. Copyright (c) 2007 S. Karger AG, Basel
