Abstrakt: Background: Grade 3 ischemia (G3I) in the 12‑lead electrocardiogram (ECG) predicts poor outcome in patients with ST-elevation myocardial infarction (STEMI). The outcome of G3I in "real-life" patient cohorts is unclear.
Methods: The aim of the study was to establish the prognostic significance of grade 2 ischemia (G2I), G3I and the STEMI patients excluded from ischemia grading (No grade of ischemia, NG) in a real-life patient population. We assessed in-hospital, 30-day and 1-year mortality as well as other endpoints.
Results: The NG patients had more comorbidities and longer treatment delays than the two other groups. Short-term and 1-year mortality were highest in patients with NG and lowest in patients with G2I. Maximum troponin level was highest in G3I, followed by NG and G2I. In logistic regression multivariable analysis, NG was independently associated with 1-year mortality.
Conclusions: NG predicted poor outcome in STEMI patients. G2I predicted relatively favorable outcome.
