How much of an impact can lifestyle changes (exercise, diet, etc.) have on preventing coronary heart disease?
Lifestyle changes can have a significant impact on preventing coronary heart disease; however, they cannot guarantee that you will not be affected. The impact will vary depending on a number of factors, including the degree to which the lifestyle changes are incorporated into one’s life, heredity, and if heart-related medications are needed (diuretics for high blood pressure, for example).
