Had the nuclear stress test and of course I was concern with not only the results but the medicine they use to get the blood going through the heart. I went on line and read where some people having this medicine experienced bad reactions. I'm happy to said I had none with the exception of a very light sinus ache which did not last long. And I'm very happy to said i got my results and the report said "low risk and no blockage'. Of course it would be better if it said no risk but i will take the low knowing that the heart problems I'm having that's a pretty good report.
