Does serum troponin-I correlate with cardiac morbidity or mortality in patients with severe thermal injury?
Mild elevation of troponin-I after severe thermal injury indicates subtle cardiac injury but does not predict overt cardiac morbidity or mortality.
Severe thermal injury was associated with a mild elevation in serum troponin-I; however, this did not correlate with overt cardiac morbidity or mortality. Postburn elevation of cTn-I suggested that a subtle degree of cardiac injury was present after a severe thermal injury despite hyperdynamic cardiac function during resuscitation.
Murphy et al. (1998) studied this question.
