Slightly less tongue in cheek, of the top 6 (since you jump to number 12 after that) we only have definite ways to reduce 1, 2 and 6. Reduction in smoking would reduce #2 by a lot and #6 we don't really know how much it could be impacted since your numbers don't separate type-1 and type-2, only one of which we know how to reduce the chances of.
Surprisingly, stress and smoking both have significant impacts on coronary heart disease, so reducing smoking and reducing stress would help with this a lot (Scotland saw a 10% reduction in CHD after the smoking ban came into place). It can also be caused by diabetes, so reducing that would also reduce CHD. The last primary cause of CHD is cholestorol, which can be caused by diabetese (hence how this can contribute to CHD), smoking (same), lack of exercise, alcohol consumption and obesity.
Diet is also a contributing factor, although there's been questions raised recently on whether this is a direct influence like obesity or alcohol (apparently consumption of cholesterol in foods like eggs is no longer considered to cause increase in the bloodstream as it's broken down during digestion) or whether it's just a case of a bad diet results in obesity and then that's what leads to CHD
Since an increase in exercise would reduce obesity and inherently reduces cholestorol, it would seem to follow that rather than banning fast food or television we should be banning cars so that people have to walk or cycle to work. This would also reduce pollution which would likely reduce issues of lung cancer and lung disease, as well as reducing road traffic accidents, reduce incedents of type 2 diabetes and, since regular exercise can increase endorphins, potentially reduce suicide rates
Oh, and of course there's no reason you have to stick with a single issue which causes deaths at once, so why not deal with guns at the same time as health conditions? It would make your walk to work safer if nothing else
