The key reason for the percentage of change in rates of death from heart disease from 1950 to today is the declines in smoking. Smoking is a major risk factor for heart disease, and as smoking rates have declined over time, rates of death from heart disease have also declined. While reductions in obesity and increased exercise may also contribute to decreased rates of heart disease, declines in smoking are the most significant factor. The availability of health insurance may also have some impact on rates of heart disease, but it is not the key reason for the decline.
