May aid phenotyping of severe vs milder disease in stable outpatients; hypothesis-generating and requires prospective validation before practice change.
Does cardiac troponin I measurement at low concentrations distinguish stable cardiovascular outpatients with severe heart disease from those with milder disease?
Cardiac troponin I concentrations below the 99th percentile can help distinguish stable cardiovascular outpatients with structural or ischemic heart disease from those with milder disease.
Schulz et al. (2006) studied this question.
