Is coronary artery disease inherited?

Sort of: Yes it runs in families so if your parents have it you are more likely to also. This is partly because risk factors such as diabetes are also inherited. It is very complicated however, much more so than hair or eye color for instance because there are so many factors to consider.

Human Dominant : Atherosclerosis, an accumulation of white blood cells in the walls of arteries, typically starts in childhood & is primarily driven by lipoproteins (proteins which transport fat in the water outside cells) is dominant human behavior yet typically ignored for decades because it remains asymptomatic until plaque ruptures releases debris, triggers clots & suddenly block blood flow. Also other issues.
