Cardiac troponin I in aortic valve disease.

Background: Plasma cardiac troponin I levels may be higher than normal in conditions other than ischemic heart disease. We aimed at measuring troponin I levels in aortic valve patients, in which increased values for left ventricular dimensions and pressure are frequently found.

Methods: Plasma levels of troponin I, creatine kinase (CK) and the MB fraction of the same enzyme were measured in a group of 25 clinically stable aortic valve patients.
