Corelation between Troponin I and the severity of coronary artery disease in patients with acute myocardial infarction

This study analyzes the relationship between the value of troponin I  and the severity of coronary lesions detected by coronary angiography in patients with acute myocardial infarction. We conducted a retrospective study on a number of 197 patients, hospitalized in the Emergency Clinical County  Hospital, Oradea, Romania. These patients were diagnosed with acute myocardial infarction (STEMI and NSTEMI) at the time of presentation to the emergency department. Also, coronary angiography was performed and the level of troponin I was determined for these patients. After using Statistix 8.0 for data analysis, the results of this study show that troponin I is an independent predictor of the severity of coronary lesions in this category of patients. Furthermore, the sensitivity of troponin I in the prediction of severe coronary lesions increases to 100% after 96 hours, if it is maintained above 1.53 ng / ml.
