I don't totally have the answer but I can repeat what my husband's cardiologist told him. He had a heart attack and almost died. One artery was 100% blocked and two were at 50%. They won't stent them until 70%. As they couldn't get an accurate blood test on my husband they didn't know for sure what was causing it and what medicine to give. They don't get a totally accurate blood test during a heart attack. It took almost 4 months to get one on him. By then the diet was already starting to work. The hospital nutritionist made the mistake of thinking it might be cholesterol. Put him on low fat,vegetables, fruit and grain.I knew that was wrong after what the cardiologist had said. The cardiologists assumed that they knew. After research and talking to nurtritionists I came up with the diet. By then he was home. When the cardiologist put him on chicken, turkey and low carb, it was almost identical to the one he was already on and the dr. said to continue doing what we were doing. they could have killed him with the hospital diet if he had stayed on it.
First of all, one must know what is causing the blockage. There is a difference between cholesterol and triglycerides.
Cholesterol diets are the low fat,fruits, vegetables and whole grains. Triglyceride diets are low sugar, low fat, low carbs even complex. So most of the foods are cut out and one gets a vitamin. In my husbands case triglycerides and cholesterol were both high and so the diet had to be extreme. The only vegetables he was allowed was squash, bell peppers, tomatoes limited, mushrooms and the greens. White turkey and chicken.
He gets fat free cheese and milk, two bread daily, splenda or artificial sweetner. He is allowed one treat meal per week.
He was not given medicine for either. As they didn't know for sure they didn't know what to give him and there are so many side effects from the meds. Within just a few months he was skinny and his blood tests were great. The cardiologist has said that it can be REVERSED.
However, since my husband was not really overweight but just by a few pounds he now is skinny and looks kind of haggard. And he continues to smoke. Which I worry about but he really has trouble quitting. He has tried. I feel so sorry for him as I quit almost 10 yr. ago and know how difficult and traumatic it is.
He has not had another angiogram to check his arteries but I am just hoping as he is that it has reversed. He says he feels good so I hope that means something. After a few months the cardiologists let him have two/three small servings of lean beef per week. But he doesn't eat that much.
Watching cholesterol is great but one has to know that the diet they put you on for that can be the worst thing you can do for triglycerides and they are dangerous.
I have done a lot of research on this and it is hard to put in just a few paragraphs. But I hope the basics are here. Check to see what is causing the blockage if you don't already know.
Good luck.
