Electrocardiographic patterns of proximal left anterior descending artery occlusion in ST-elevation myocardial infarction may be modified by 3-vessel coronary artery disease
Journal of Electrocardiology, 05/10/2012
Neeland IJ et al. – Electrocardiographic changes in proximal LAD STEMI may be modified by the presence of significant atherosclerotic disease elsewhere in the coronary vasculature. Recognition of this ECG pattern may aid the clinician in the rapid identification of high–risk STEMI.Methods
- Authors describe the ECG findings in 2 cases of proximal left anterior descending (LAD) artery occlusion in ST–elevation myocardial infarction (STEMI) associated with 3–vessel coronary artery disease.
- Both patients had atypical ECG patterns of ST–segment elevation in leads V2, I, and aVL and ST–segment depression with positive T waves suggestive of extensive subendocardial ischemia in leads II, III, aVF, and V3 through V6; acute proximal LAD occlusion and concomitant 3–vessel coronary artery disease were observed angiographically.
