Not necessarily. You are by virtue of your age and sex in a high risk group for coronary disease. Your symptoms are consistent with heart problems and a noninvasive diagnostic test indicates that a blockage is present. The only way to be certain is to proceed with the angiogram and then treat based on the findings. Of course a second opinion is always a good idea if you don't feel confident in the doctor you have been seeing. Hope this helps. Let us know if there is anything else we can do.
