| CHD incidence is on the rise worldwide and is a major cause of death in developed countries. It results in approximately one-third of deaths in individuals over the age of 35 years (Sanchis-Gomar et al., 2016). In 2016, the Heart Disease and Stroke Statistics reports that 15.5 milllion people in the USA over the age of 20 have been diagnosed with a manifestation of CHD. In the USA, approximately one-half of middle-aged men and one-third of middle-aged women develop CHD (Sanchis-Gomar et al., 2016). Despite increasing prevalence, age-standardized death rates have decreased by 22% since 1990 due to a shift in age demographics. The lifetime risk of developing CHD in individuals with more than 2 risk factors is 37.5% for men and 18.3% for women (Sanchis-Gomar et al., 2016). Estimates show that men over the age of 40 and women over the age of 45 are at most risk of CHD. Prevalence of CHD increases with age for both men and women (Sanchis-Gomar et al., 2016). | CHD incidence is on the rise worldwide and is a major cause of death in developed countries.
