I did this same research myself and some top ways I found for risk reduction:

• Don't smoke
• Vegetarian diet
• Red Yeast Rice or Statin to keep non HDL cholesterol very low.
• Pine Bark Extract for artery health
• Avoid processed oils
• Avoid processed sugar
• Consume nitrates such as beets daily to boost nitric oxide
• Consume garlic

If you follow these and keep your non-HDL cholesterol very low, like under 60, then you'll probably not have a heart attack according to the Framingham risk assessment. Your risk will be less than 1% over 10 years.

A few things to note from what I found in my studies is that diet while it does play a role does not play the main role in terms of cholesterol plaque formation. Inflammation seems to play the main role which diet exacerbates but something like smoking cigarettes seems to be worse than eating fast food. This isn't to say it's a good idea to eat McDonalds on a daily or even weekly basis but to say that it's not necessarily the food which causes the plaque or the unstable plaque (which is one of the main causes of heart attack). Certain supplements promote plaque stabilization and these are good and keeping a very low non-HDL cholesterol level even promotes plaque regression which is very good.
