My Name Is James And I Had 4 Bypasses About

My name is James and I had 4 bypasses about 20 years ago and 3 years ago I had 3 stents put in because of blockages in one vessel, most resent in April this year I had another stent put in because of scar tissue had blocked another vessel. The Dr. said that the next procedure would be to go to Washington DC where they would use radiation to remove the blockage. What is your thought. I started having problems again about a month ago. My Age is 74.
