Abstract
INTRODUCTION: T-wave inversion (TWI) is a common ECG finding in patients with acute pulmonary embolism (APE). OBJECTIVES: To determine the prevalence of TWI in patients with APE and to describe their relationship to outcomes. METHODS: Retrospective study of 437 patients with APE. TWI patterns were described in two distributions: inferior (II, III, aVF) and precordial (V1-V6). RESULTS: TWI was observed in 258 (59%) patients. The mortality rate was significantly higher in the group with TWI in the inferior AND precordial leads compared to the group without TWI (OR: 2.74; p = 0.024) and the group with TWI in the inferior OR precordial leads (OR: 2.43; p = 0.035). As compared those with TWI in <5 leads, patients with TWI in ≥5 leads experienced significantly higher rates of death (17.1% vs. 6.6%, OR: 2.92; p = 0.002) and complications. CONCLUSIONS: TWI and the quantitative assessment thereof can be useful to risk stratify patients with APE.
