Hello. Thank you for your question and welcome to HCM. I carefully read your query.
First of all, I believe that you know what does a
chest pain originated from coronary arteries feel like. This is called
angina, and is more like a severe heaviness or tightness in the mid chest and which spreads to the left arm.
Sharp pain with highest probability does not reflect a pain originated from a blockage in the coronary arteries. On the stent side, since it has been seven years you underwent
stent implantation, I assume that the stents are patent and working well, since the highest probability for them to narrow is within 6 to 12 months after implantation, depending from the stent placed. However, once you had coronary
artery disease, although treated at that time, you have a independent risk factor to develop coronary artery disease again. I would recommend you to undergo a cardiac
stress test, based on the above mentioned fact, and the strain you felt in your heart area. As for the sharp pain in your left arm, my opinion is that it is not connected to coronary arteries.
I hope I was of help. Kind regards.
Dr. Meriton
