A 42 year old smoker has developed an acute anterior wall myocardial infarction. The coronary angiogram done on him is likely to show an obstruction of the -
Left anterior descending aery
Left posterior descending aery
Right coronary aery
Circumflex aery
Occlusion of the left anterior descending coronary aery (LAD) may cause infarction of the anterior wall of the left ventricle, manifested as precordial ST-segment elevations. Inferior ST-segment elevations due to occlusion of a LAD may reflect an ischemia of wrapped LAD aery . Ref Davidson 23rd edition pg444
