High-Sensitivity Troponin T Plasma Levels in Patients With Aortic Stenosis (Tyrolean Aortic Stenosis Study-2)

This study is measuring levels of a heart stress protein called high-sensitivity troponin T in the blood of patients with aortic stenosis — a narrowing of the heart's main outflow valve — to see if this blood test can predict which patients are at higher risk for complications. **You may be eligible if...** - You have aortic stenosis (narrowing of the heart valve) confirmed by an echocardiogram or heart catheterization **You may NOT be eligible if...** - You have recently had a heart attack (acute coronary syndrome) - You have an active infection of the heart valve (endocarditis) Talk to your doctor to see if this trial is right for you.
