Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate whether vWF (von Willebrand multimer ratio and CT-ADP) changes over time as a result of exercise in patients with moderate aortic stenosis and asymptomatic severe aortic stenosis and to determine the mean time from the start of exercise to the peak of vWF change. This pilot study will be the first study to address this question. | — |
Secondary
| Measure | Time frame |
|---|---|
| To assess the relationship between changes in vWF during exercise and adverse events (death, AVR/TAVI, heart failure, syncope, angina, bleeding). We will follow up the patients untill 1 year after the exercise test and ask them the appearence of the adverse events. | — |
