Troponin T elevation in lobar lung disease.

Two patients with a rise in cardiac troponin T (cTnT) concentrations during the course of lobar pneumonia, without any evidence of acute coronary syndrome or renal failure, are presented. The increase in cTnT concentration is considered a highly sensitive marker of cardiac injury, although it may also rise in other conditions and as a result of lobar pneumonia. Thus, this effect should be considered when the possibility of acute coronary syndrome in such patients is addressed.
