Hi,
Thanks for writing to Health Care Magic, I am Dr Asad Riaz, I have closely read your question and I understand your concerns, I will hereby guide you regarding your health related problem.
A block in the arteries supplying blood to the heart muscle usually manifests as having
chest pain or ECG changes on exertion and
heart attack as an ocassional grave consequence
If your treating doctor saw sone hanges in your ECG upon exercise or if you developed any chest pain, it may predict upto 75-80% accuracy the existence of a blockage in those vessels.
If you get it looked at, as your doctor advised, and get it managed by placement of stents, it may prevent the development of another heart attack. So yes, you should absolutely get it done
I hope this answered your question, if you have more feel free to ask.
Regards.
Dr.Asad Riaz.
General and Family Physician..
