Can atherosclerosis be cured?

No: Medications and life style changes can prevent it from progressing and at times cause some regression, but will not cure it.

Yes, Up To a Point: Aggressive reduction of low density lipoprotein (fat carrying protein) particle concentrations along with a high number of functional large high density lipoprotein particle concentrations can prevent and reverse atherosclerosis, up to a point. Keeping blood sugar & blood pressure low, not smoking, etc. Also important. However, our bodies rebuild based on previous structure - thus there are limits.
