title: Ask the doctors. I went to the emergency room with mild chest pains. Some blood work was done, and the doctor on duty said I had a heart attack. This prompted a cardiac catheterization which revealed that I had no blockages. The cardiologist told me that I hadn't had a heart attack. Why the confusion?
