Patients who presented with anterior STEMI and underwent primary percutaneous coronary intervention between January 2008 and March 2011 were included. For each subject, a transthoracic echocardiogram that was performed within 24 hours of admission was interpreted by an independent investigator blinded to the patient's electrocardiographic data.
Of the 65 subjects who met our inclusion criteria, 30 had AS-STEMI and 35 had EA-STEMI. No differences were observed between groups in baseline characteristics or the mean number of hypokinetic, akinetic, and dyskinetic segments. Apical inferior segment dysfunction occurred more often in patients with EA-STEMI than in patients with AS-ASTEMI (71.4 % vs 43.3 % ;
The term AS-STEMI may be misleading, as it implies that only the anteroseptal segments are involved. We show that regional dysfunction in patients with AS-STEMI extends beyond the anteroseptal region.
