Levels between 0.04 and 0.29 ng/ml are nonspecific and may be encountered in a variety of cardiac conditions such as myocarditis, arrhythmias, congestive heart failure, ischemia, angina, invasive cardiac procedures, and developing or resolving myocardial infection.
Levels above 0.29 ng/mL are usually associated with infarction, although mild elevations above 0.29 ng/mL may be present with non-infarction cardiac abnormalties
