Abstract
OBJECTIVES: Ejection fraction (EF) and end-systolic volume index (ESVI) are established predictors of outcomes following ST-segment elevation myocardial infarction (STEMI). We sought to assess the relative impact of infarct size, EF and ESVI on clinical outcomes and left ventricular (LV) remodelling.
DESIGN: Prospective cohort study.
SETTING: Academic hospital in Chicago, USA.
PATIENTS: 122 patients with STEMI following acute percutaneous reperfusion.
MAIN OUTCOME MEASURES: Death, recurrent myocardial infarction (MI) and heart failure.
METHODS: Cardiac magnetic resonance imaging was obtained within 1 week following STEMI in 122 subjects. ESVI, EF and infarct size were tested for the association with outcomes over 2 years in 113 subjects, and a repeat study was obtained 4 months later to assess LV remodelling in 91 subjects.
RESULTS: Acute infarct size correlated linearly with the initial ESVI (r = 0.69, p
