I have just come out of hospital after chest pain and shortness of breath. I am told by the heart team that I didn't have a heart attack, however they found a small level of troponin (24) in my bloods and I was told that it raised between the 2nd and 3rd blood test. I thought that unless there was something wrong with your heart troponin was not present. Everything else came back normal. Can anyone clarify what it could be as everyone thinks I had a panic attack. I am awaiting an echo test.
