Difference in rest and peak exercise of AV velocity, CT-ADP and loss of vWF HMWMs
| At rest (n=10) | At peak exercise (n=10) | P value | |
| Maximal AV velocity (cm/s) | 359±56 | 411±56 (n=6) | 0.046* |
| CT-ADP (sec) | 138±31 | 138±65 | 0.45* |
| HMWM ratio | 0.59±0.22 | 0.61±0.17 | 0.65* |
*Wilcoxon Signed Rank test used; p<0.05 was considered significant. Summary values represent number (%) or mean±SD.
AV, aortic valve; CT-ADP, closure time with adenosine diphosphate; HMWMs, high-molecular-weight multimers; vWF, von Willebrand factor.
