This study looks at the value of investment in health care for overall health care expenditures as well as for expenditures for the management of four key health conditions -- heart attack, type 2 diabetes, stroke, and breast cancer. Evidence from a variety of sources shows that the value of the health gains during this time period are higher than the increased health care expenditures during this time period, indicating that these additional investments in health care add value to the U.S. population.
