Silent ST segment elevation myocardial infarction with multi-segmental renal infarction: an unusual presentation.

A 36-year-old diabetic man came to our institution presenting with constant left flank pain. Left renal embolic infarction was found by abdominal computed tomography. Silent ST segment elevation myocardial infarction was noted on 12-lead electrocardiogram. Emergent coronary angiography revealed large thrombus burdens with complete occlusion at the left anterior descending artery ostium, which may be the embolic origin. Silent ST segment elevation myocardial infarction with acute flank pain and multiple segmental renal infarction is an unusual presentation. High vigilance may prevent delay of the "golden hour" to treat acute myocardial infarction.
