Grafts: Saphenous vein grafts t the right coronary artery and the left anterior descending artery are 100% occluded.
Johnwen, he has experienced restenosis in his by-pass veins. (I haven' looked over your entire case, but if you haven't had bypass surgery, than I am confused!) This is the problem with bypasses and stents - the damn arteries keep trying to heal!
So your doctors aren't "too concerned" (because you are still alive and breathing and the only thing that seems to have failed, is their treatment - your bypasses.)
The cholesterol level tells me that your body is still fighting the fires (and producing cholesterol to deal with it). The way I would deal with that would be to increase vitamin C (and lysine and proline. Proline because if your bypasses are already occluded, there is no theoretical reason not to add back the proline)
I hope johnwen chimes in, but I think you are on the right track sticking with the Pauling therapy, although in our experience, there needs to be blood flow for an occluded artery to reverse and become normal.
Another thought from all the readings on cancer lately, is that the commonality among alt. cancer treatments is to get oxygen to the tumor/cancer. I know that a doctor having a heart attack saved his own life by going immediately into a hyperbaric oxygen chamber. So how do we increase oxygen to the heart? An idea out of the blue (or universe) for you, with occluded arteries, is to look for ways to "oxygenate" your heart.
For example, gemmanium http://www.cancertutor.com/germanium/
Organic germanium helps enrich the body with oxygen and is a superb anti-oxidant.
