How common is coronary artery disease cad?

Depends: Coronary artery disease is the #1 killer of adults in the United States ahead of cancer. Your individual risk of coronary disease is based on your risk factors. The risk can be predicted using a publicly available risk predictor: http://www.Medcalc.Com/heartrisk.Html.

Dominant Behavior: The key issue: atherosclerosis, an accumulation of white blood cells in the walls of arteries, typically starts in childhood & primarily driven by lipoproteins (the proteins which transport fat in the water outside cells) is dominant human behavior yet is typically ignored because it remains asymptomatic for decades until plaque rupture releases debris, triggers clots & suddenly blocks blood flow.
