Dear sir,  I am a 60-year-old male. I did angioplasty in RCA one month back my LAD contains 50-60%. My questions are:  whether I have to take both Asprin and Clopidogrel or only Clopidogrel is enough. Because after I take Asprin with Pantoprazole I am getting severe epigastric pain.

For LAD what investigations and treatment I should do? Thank you. Kind regards.
