From: Residual ST-segment elevation to predict long-term clinical and CMR-derived outcomes in STEMI
Examples of Q-STE and structural changes at 6-month CMR. Pre-discharge ECG showing no Q-STE (A) and Q-STE in ≥ 2 leads (B). Short axis CMR in diastole (left) and systole (right) indicating preserved (C) and reduced (< 40%, D) LVEF at 6 months. Late gadolinium enhancement imaging depicting non-extensive (E) and extensive (> 30% of LV mass, F) IS. Abbreviations: CMR = cardiac magnetic resonance. IS = infarct size. LV = left ventricular. LVEF = left ventricular ejection fraction. Q-STE = Q wave and residual STE > 1 mm.
