I am 62 and have a history of one heart attack. 8 years ago I had a stress test with chemicals and ran into problems on treadmill. That day I was stented but doctor assured me it was not the chemical that caused the problem and was not a heart attack. I now have a pacemaker. They want me to do another nuclear stress test and after all I have read about the dangers of the nuclear stress test ie. heart attacks I am absolutely frozen with fear to do another one. I am not by nature a fearful person but the fear I felt when I had my heart attack never left me. Then the fear I felt when I was on the treadmill that day when I ran into problems only made my fear worse. Now I am terrified. My gut is telling me no stress test. I may add I failed my echo stress test last year but again I think I failed because I was afraid to keep going. I would go to see a counselor for fear of a major panic attack during test..but that does not reassure me I won't run into big problems again. Help :)
