I am a 52 yr. old healthy woman who was admitted last week because my troponin levels were 2.17 four times (every 6 hours) I had mild chest discomfort, but had been having problems breathing when I went up a flight of stairs. I exercise on an elliptical trainer 4 days a week and thought I was a picture of health. My bp runs 100/60, my heart rate is 65-70, my heart cath is completely clear, echo cardiogram is perfect, no blood clots in legs, no pulmonary embolisms........what in the heck caused this? Is 2.17 really that high?
