Detailed Answer:
Hello Sir
After going through the medical details provided by you I would like to tell you that your symptoms are suggestive of Angina equivalent and need through cardiac evaluation.
As you already had a stent in your system which was deployed more than 11 years back and there was a 57 % blockage also, so it's time to get an check coronary angiogram done to see the status of the stent and the degree of progress of the disease.
So its highly advisable that you should personally consult your cardiologist for proper evaluation and treatment plan.
Till that time just keep a sublingual Sorbitrate tablet with you in case you feel any severe chest discomfort.
I hope this information will be helpful. Feel free to ask back if you have any more doubts.
Kind regards
