I have had intense heart attack like symptoms 4-5 times.. i always go to er n get ekg n trop I tested.. the last 4 times trop I was 0.001 ng/ml so practically zero but this time it has come out 0.01 ng/ml ( ekg normal) Wouldn't this rise from baseline levels concerning ? The ER told me that they wouldn't bother about such fluctuations unless it increases above 0.03 I am seeking a second opinion . I had done echo tmt last month, so don't know if it has to be repeated.
