The cTnTG4 Plasma Levels in Relation to Electrocardiographic and Echocardiographic Abnormalities in Patients with Acute Coronary Syndromes without ST Segment Elevation – Study on 123 Cases

Abstract

“The universal definition of the myocardial infarction” developed by the Joint ESC/ACCF/AHA/WHF Task Force in 2007 provides precise criteria for the NSTEMI but the early diagnosis of the non-ST elevation acute myocardial infarction (NSTEMI) is a challenge in the patients presenting soon after the onset of chest pain. Diagnostic difficulties are caused by the atypical clinical and imaging ischemic changes and by the asynchronous occurrence of these changes. We studied 123 patients with acute coronary syndromes admitted to the hospital in the first 6 hours after the onset of chest pain and asses the diagnostic contribution of cardiovascular risk factors, ischemic changes on resting electrocardiogram and on bedside 2D echocardiography in the early diagnosis of NSTEMI. The association of old myocardial infarction or stroke with wall-motion abnormalities on the bedside transthoracic 2D echocardiography seems to be a predictor for early diagnosis of NSTEMI in patients with acute coronary syndromes.
