Summary

This study looked at how certain heart devices change a blood-clotting protein called von Willebrand factor. Researchers studied 500 adults with heart failure or aortic stenosis who received a mechanical heart pump or a valve replacement. The goal was to understand when these protein changes start and stop, and how they relate to patient outcomes.
