In order to examine gender related differences in left ventricular geometry, diastolic filling. exercise capacity and functional status, 45 male and 24 female subjects with asymptomatic aortic stenosis (AS) were evaluated with 20 and Doppler echocardiography before and immediately after Bruce protocol treadmill exercise tests. Functional status was assessed by a standardized questionnaire using a 0–100% scale. There was no difference in AS severity between men and women (maximal AS jet velocity 3.5±0.6 vs 3.6±0.6 m/s. p=NS; aortic valve area index 0.7±0.2 vs 0.6±0.2 cm2/m2. p=NS).
