The role of Tei index added to the GRACE risk score for prediction of in-hospital MACE after acute myocardial infarction

Abstract

Introduction: The Global Registry of Acute Coronary Events (GRACE) risk score is widely recommended for risk assessment in patients with acute myocardial infarction (AMI). Variable degrees of impairment in left ventricular (LV) systolic and diastolic function might be found after AMI. Tei index is an echocardiography parameter that represents both systolic and diastolic LV performance. Previous studies demonstrate Tei index as an independent predictor of Major Adverse Cardiovascular Events (MACE) after AMI. This study investigates whether the addition of Tei index could improve the GRACE risk score performance to predict inhospital MACE after AMI.
