Cardiac Troponin I as a Predictor of Arrhythmia and Ventricular Dysfunction in Trauma Patients With Myocardial Contusion

Abstract

Levels of cTnI below 1.05 microg/L in asymptomatic patients at admission and within the first 6 hours after admission rule out myocardial injury, whereas positive cTn levels above 1.05 microg/L mandate further cardiologic workup for the detection and management of myocardial injury. Furthermore, the dynamics and peak levels of pathologic cTnI levels allow estimation of arrhythmia risk and left ventricular dysfunction in trauma patients with myocardial contusion.
