Scores ranged from negative 200 to positive 200; the more positive the score, the lower your mortality risk in the next 10 years. Some conclusions in the study: patients between 0 and negative 100 had an 11 percent chance of dying in the next 10 years, while those in the negative 100 and below range had a 38 percent chance of death. The risk of death was calculated in this study by age, gender and fitness level and results from an elegantly simple equation, as Senior study author Michael Blaha demonstrated. The importance of the study is the possibility to work to improve the score. Everybody have the power to change.
