Clogged arteries symptoms and conditions

I've had a heart attack at age 46 (2000) and had two stents put in. I have been on various cholesterol medicines. If my cholesterol went down my triglycerides went up, leg pains were horrible. In 2004 the Dr did another angioplasty my arteries looked clear. In 2007 I started having chest pains and went in for another angioplasty, I had two 90% blocked arteries and One 70%. I have been taking Vytorin for over two years, I started with 10/20, I had moderate cholesterol and a little high in triglycerides, and a little high in my liver enzymes. My doctor increased me to 10/40 since the angioplasty, yes everything dropped in to normal ranges except my liver enzymes which have now doubled.I have had very strange eye attacks, it is like my eyes go numb, anxiety attacks, depression, horrible lower back ache by my hips, shoulder pain coming on lately. The good thing is that this comes and goes, it is not constant, but when it hits it is bad. One thing I think I have been an example for, is Vytorin doesn't work any better than anything else, because if it did I wouldn't have had 2 more blocked arteries,
Now I am concerned about the 3rd one he did not put a stent in it and upped my dosage hoping it would keep it from clogging. I fear I am doomed...
