Comparison of segmental wall motion abnormalities on echocardiography in patients with anteroseptal versus extensive anterior wall ST-segment elevation myocardial infarction.

Objective: Acute anteroseptal ST-segment elevation (STE) myocardial infarction (AS-STEMI), defined as STE limited to leads V1 to V3, has historically been associated with a smaller infarct size than extensive anterior STEMI (EA-STEMI), in which STE extends to leads V4 to V6. We compared the differences in global and regional wall motion by transthoracic echocardiography between patients with AS-STEMI and EA-STEMI.

Methods: Patients who presented with anterior STEMI and underwent primary percutaneous coronary intervention between January 2008 and March 2011 were included.
