Hi John. Thanks so much for your comments for me. It's at times not so easy to get answers from the MDs at the VA. I did learn a bit more recently and I was told by one VA ER MD (a cardiologist) that the diagonal artery (which comes off the LAD) had been freed of the blockage apparently caused by putting the stent (a DES type one) into my LAD (but then my own VA MD told me yesterday something about this which, as I recall, clashed with what the ER cardiologist told me). Yesterday I spoke with my own VA MD and he prescribed another nitro type drug which I'm to take every day---> isosorbide mononitrate. I already have the tiny nitro pills that go under the tongue in case of an emergency. My MD said I have CAD, coronary artery disease. He told me it's possible to live with this for another 20 years but I'm not so sure after what's happened to me in life. He said he'd enroll me in physical therapy's heart rehab program so I'll certainly want to know what I can and can't do physically. Later this month I meet with a VA cardio clinic PA so I'll have to prepare my questions and concerns.
