This appears to be the Circulation study that you cite: Kahn et al., 2008, "The Impact of Prevention on Reducing the Burden of Cardiovascular Disease". The full-text is free.
The authors of the Circulation study estimate that fully implementing all eleven prevention activities which they discuss would increase US medical spending by $7.6 trillion during the next 30 years, increasing medical spending on cardiovascular disease, diabetes, and coronary heart disease from $9.5T (their baseline estimate) to $17.1T (with $0.9T in savings from better prevention more than offset by $8.5T in new preventive spending). *
Note that these numbers are only for the effects of preventive care on medical spending; they do not include the health benefits of the preventive care. The authors also estimate that fully implementing the prevention activities would prevent 63% of all heart attacks and 31% of all strokes, increasing adult life expectancy by over a year. In total, the $7.6 trillion would buy 244 million additional quality-adjusted life-years, for an average cost of $36,380 per QALY.
* I notice that I am confused: the number "162%" appears in the paper in reference to this spending increase, but I can't figure out what it refers to. Going from $9.5T to $17.1T is an 80% increase.
In line with the results of the poll here, a thread for discussing politics. Incidentally, folks, I think downvoting the option you disagree with in a poll is generally considered poor form.
1.) Top-level comments should introduce arguments; responses should be responses to those arguments.
2.) Upvote and downvote based on whether or not you find an argument convincing in the context in which it was raised. This means if it's a good argument against the argument it is responding to, not whether or not there's a good/obvious counterargument to it; if you have a good counterargument, raise it. If it's a convincing argument, and the counterargument is also convincing, upvote both. If both arguments are unconvincing, downvote both.
3.) A single argument per comment would be ideal; as MixedNuts points out here, it's otherwise hard to distinguish between one good and one bad argument, which makes the upvoting/downvoting difficult to evaluate.
4.) In general try to avoid color politics; try to discuss political issues, rather than political parties, wherever possible.
If anybody thinks the rules should be dropped here, now that we're no longer conducting a test - I already dropped the upvoting/downvoting limits I tried, unsuccessfully, to put in - let me know. The first rule is the only one I think is strictly necessary.
Debiasing attempt: If you haven't yet read Politics is the Mindkiller, you should.
