Massive study tracks 3,450 patients with aortic stenosis to uncover prognosis clues

This study follows 3,450 patients with aortic valve narrowing (aortic stenosis) to better understand their long-term outlook. Researchers will look at ultrasound measurements and other factors to find what predicts how the disease progresses. The goal is to improve how doctors assess risk and make treatment decisions, but no new drug or procedure is being tested.
