Tessa0825,
Thanks for the post.
(1) "Considering that, am I to assume that the chest pains can now be safely attributed to esophageal spasms?"
A dobutamine echo is about 85% accurate for accurately detecting significant coronary artery disease. Although this is pretty good, it still means that 15/100 cases are missed in the entire population. However, in a low risk person, the chance of having coronary disease after a negative is test is much less than 15% (this is due to a statistical oddity predicted by Bayes Theorem).
(2) "Is Toprol only for angina pains or will it also help the HBP and is that probably why Im to continue it even though I've been given coronary clearance?"
No, toprol is used to treat many things: hypertension, palpitations, afib, angina, and infrequently, esophageal spasms.
(3) "Im just a little confused as to how the toprol can seem to be helping so much if the pains are in fact esophageal related?"
Beta-blockers do help relieve some people of their esophageal spasms. Alternatively, you could be feeling better due to placebo affect, or (less likely) treatment of angina.
(4) "Could the high diastolic number on my BP be responsible for the chest discomfort?"
Yes, it is possible, although unlikely. Hypertension certainly precipitates chest pain in some patients with coronary artery disease.
Good luck.
