Abstract INTRODUCTION: Terminal T wave inversions (TTWI) indicate advanced stages of ST-elevation myocardial infarction (STEMI). The present study investigated whether TTWI predict unfavorable in-hospital outcomes in STEMI patients treated with urgent percutaneous coronary intervention (PCI). METHODS: A retrospective cohort study was performed with consecutive 188 STEMI cases undergoing urgent PCI. The primary endpoint was in-hospital major adverse cardiac event (MACE), and the secondary endpoints were ST resolution (STR) after PCI and length of stay (LOS). RESULTS: TTWI on presentation were independently associated with higher incidence of in-hospital MACE (adjusted OR 2.8; 95\% CI 1.1-7.0; p=0.03), inadequate STR (adjusted OR 5.5; 95\% CI 2.1-14.3; p=0.01), and longer LOS (adjusted mean increase 4.1 days; 95\% CI 0.3-7.9; p=0.03). TTWI predicted these outcomes better than patient-reported ischemic time or pathologic Q waves. CONCLUSIONS: TTWI on presentation are an independent risk factor for poor inpatient prognosis among patients presenting with STEMI undergoing urgent PCI. Copyright © 2013 Elsevier Inc.
