I hope there are some on this board who knows about terms like ejection fraction. I had a bad episode of chest and shoulder pain over 1 year ago. Final diagnosis that morning(the attack was night/morning) was cramps in the esaphagous. However no blood tests were taken that day(I was in vietnam), mainly because of a quite normal ecg. I later went to a heart specialist in Bangkok, who measured my troponin t values to 0.18 which was borderlin he said. He then made my do a echo and a stress test, which lead him to conclude that my heart was doing fine, and that i had no heart attack. My ejection fraction was 70%. Is a high ejejction fraction enough evidence against heart attack. Can I trust this heart specialist when he says that there was no heart attack on the grounds of an echo and a stress test.
