Ecg 12 leads: normal sinus rhythm,possible left atrial enlargement,inferior infarct,acute mi / stemi, abnormal ecg when compared with ecg of 30-mar-2015 st elevation now present in inferior leads. but troponins are ok. is it heart attack?

Repeat EKG: Computer interpretation is often wrong, not surprisingly. If no chest pain and cardiac enzymes are normal-likely, it's not a heart attack. There are several other causes of ST segment elevation besides a heart attack. I would repeat EKG and have it interpret from your cardiologist. Good luck.

STEMI: In your case the troponin should matter less than your abnormal EKG. They may want to at least consider an ECHO to look at your heart in more detail.
