Recently I emailed you a question relating to my catherization 1 yr after CABG (1 sequential svg closedf and a 60% blockage in a branch off the LAD). I asked if I was at risk for a heart attack still and you said yes. I hate to be so stupid but my dr has never answered the question and others have asked the same question. What puts me at risk for a heart attack? The blockage in the branch off the LAD or the spasming arteries? What the Dr said was if the branch closes over time I would not have a heart attack. Is that true?
