Is arteriosclerosis inherited?

Sort of. Well it's not inherited like your eye color but the tendency to develop it is inherited related to many factors. High cholesterol, hypertension, diabetes and other risk factors are also inherited to a degree. So the bottom line is that if your parents have arteriosclerosis you are at greater risk. It would be even more important to modify your risk factors.
Human Dominant & Yes. Artery disease, typically starting in childhood (without symptoms) is human dominant behavior, though with significant individual variability. Genetics, lipoproteins (complex protein particles which transport all fat molecules in the water outside cells; not cholesterol), above low normal blood glucose & blood pressure (+ additional more minor factors) are the dominant drivers/inhibiting issues.
Atherosclerosis. It does 'run in families' but isn't a pure inherited disease.
