I'm sorry you're not doing well. Despite the fact that your dobutamine stress test
was normal, your history is highly suggestive of a heart problem. Dobutamine stress tests are only about 90% sensitive (meaning they miss coronary artery
disease about 10% of the time), and the fact that you had to be given atropine
to increase your heart rate
could have reduced the sensitivity of your test even further. I suggest you return to your cardiologist as soon as possible to discuss the next step in your evaluation. I'm not convinced that coronary artery disease has been ruled out here.
I hope you have some answers soon!
