To go further, you break down the root causes for heart disease. I don't have the numbers right in front of me and don't really have the time to research them all at this time of day while I'm trying to catch up from the past 2 weeks. But suffice to say the leading indicators have reportedly been tobacco use and obesity. So you again break down the leading indicators (I believe obesity has surpassed tobacco but won't swear to it) and you'll find the obvious two...diet and exercise. Now you would be hard pressed to force people to exercise, but you could offer incentives to businesses that encourage and support daily exercise programs, increase your physical activities at public schools, etc. You could also look at the root cause of dietary problems such as high-fructose corn syrup (which the government could do something about) and whatever other factors can be identified through in-depth analysis.
Not only would you be saving more lives, you would decrease the need for medical visits thereby lowering insurance costs. Lower insurance costs would result in less of your population lacking adequate coverage.
