I am sure you have been told that you are extremely lucky to have survived the deadly 'widow maker lesion' and have had the rare chance of having had a stent
put in in time.
The medications prescribed by your cardiologists are your life line and ,under no circumstances , you should doubt them or think of doing a self modification; this latter may be deadly.
For any symptom you should consult your cardiologists as they know your heart better.
Hope this answers your question.
