<s>[INST] Hello doctor, I have chest pain and shortness of breath. It started on 16th March. Since then, it is still present, continued discomfort in chest and back. I am on 5 mg of Atorvastatin. [/INST] Hello. I have gone through your reports. (attachment removed to protect patient identity). Resting ECG and echo showed no abnormalities, and stress test does not show any abnormalities, although could not be completed. So, we cannot be certain that this is not cardiac pain, but appears to be less likely. So you should undergo further testing with either pharmacological stress test or CT (computed tomography) coronary angiography. Now normal BNP (brain natriuretic peptide) level is against cardiac cause for shortness of breath. Your thyroid shows significant abnormalities, you need to be on thyroid supplements like Eltroxin and should begin as soon as possible. Now do you get this chest heaviness at rest or on exertion? If this heaviness occurs at rest only then possibility of other causes like acid reflux should also be considered especially if you have other symptoms. You should try antacid then. If heaviness classically occurs on exertion and relieves with rest then strongly suggest cardiac cause only and then should undergo further cardiac resting. So possibility of non-cardiac cause should also be suspected, however, should undergo further cardiac evaluation. I hope this helps. </s>
