Epidemiology
Roughly 6.3 million Americans are estimated to experience angina. Angina is more often the presenting symptom of coronary artery disease in women than in men. The prevalence of angina rises with increasing age, with a mean age of onset of 62.3 years. After five years post-onset, 4.8% of individuals with angina subsequently died from coronary heart disease. Men with angina were found to have an increased risk of subsequent acute myocardial infarction and coronary heart disease related death than women. Similar figures apply in the remainder of the Western world. All forms of coronary heart disease are much less-common in the Third World, as its risk factors are much more common in Western and Westernized countries; it could therefore be termed a disease of affluence. The adoption of a rich, Westernized diet and subsequent increase of smoking, obesity and other risk factors, as chronicled in The China Study, has already led to an increase in angina and related diseases in countries such as China.
Recently, angina was tied to exposure of Bisphenol-A among adults in the US.
