Isolated noncompaction of the left ventricle can present as acute ST-elevation myocardial infarction in young adults without atherosclerotic coronary artery disease.
LVNC may mimic STEMI in young adults with normal coronaries; extends embolic associations but remains hypothesis-generating.
We report a 20-year-old male who presented with acute ST elevation myocardial infarction (MI). He was thrombolyzed successfully. Detailed workup revealed no coronary risk factors and normal coronary arteries. He had echocardiographic features of isolated noncompaction of left ventricle. This is a rare cardiomyopathy and is associated with embolic events. To the best of our knowledge, this entity presenting as acute MI in a young adult in absence of atherosclerotic coronary artery disease has not been described before.
