Open Access Abstract Introduction Elevated troponin levels indicate myocardial injury but may occur in critically ill patients without evidence of myocardial ischemia. An elevated troponin alone cannot establish a diagnosis of myocardial infarction MI yet the optimal methods for diagnosing MI in the intensive care unit ICU are not established. The study objective was to estimate the frequency of MI using troponin T measurements 12-lead electrocardiograms ECGs and echocardiography and to examine the association of elevated troponin and MI with ICU and hospital mortality and length .
