question: Twelve. Weeks ago I had a heart attack , I needed to have stent surgery and they implanted 2 stents, afterwards I still have angina not all the time but a couple of times a week, after going back to see the doctor who did the surgery he thinks it would be best to do 2 more stents in another artery which has 3 narrowings, this is planned for  January how safe is it to do this so soon after the last op a?
