Brief Answer:
Probably nothing related to the heart

Detailed Answer:
Hello and thank you for your question. Welcome to HCM. I understand your concern.

The thing with the coronary artery blockages is that the more tests are conducted, the closer we get to the confirmation/exclusion of this condition. For instance, if an EKG is normal, it is a good thing, but it only evaluates the heart electricity during rest. Further, when a stress test comes back negative, we are almost hundred per cent sure that there are no (significant) blockages in the coronary arteries, which would produce clinical symptoms and/or changes in the exertion EKG, which would point towards coronary disease. If these two tests are normal in your case, then I recommend you that there is nothing to be worried about. If this becomes worrisome to you, an angio computed tomography (CT) of the aorta and the coronary arteries, would further help us in diagnosis.

As about the aortic root widening, yes, it may be found wider than normal in some people. But, it always has some cut-off ranges according to which we might expect clinical symptoms. Even when it is so, the predominant symptom is breathlesness, rather than chest pain. Since you were discharged, I come to the opinion that we have to deal with a slightly dilated aortic root. In these cases, treatment of this waits, and regular, periodical (once in six months or once in a year) controls with echo cardiogram become imperative, because it is recommended to dynamically assess the progression of the widening. I also do not think that the aortic root widening is causing the symptoms. In this scenario, I would recommend a plain chest X-ray, to assess the withing ribcage structures, linings like pleura and pericardium, and the lung tissue. If there are no organic findings about this chest pain are found, then we can assume it may be the stress factor that originates the pain.

I hope I was helpful with my answer. I am happy to help, if you have follow-up questions.

Best regards,
Dr. Meriton
