You can slow progression of arteriosclerosis by controlling your risk factors: blood pressure goal <130/80mmhg; ldl goal< 100mg/dl; daily aerobic exercise > 45 minutes; not smoking; staying close to normal BMI of < 25kg/m2; if you are diabetic, keep good control with A1c goal < 7.

Thus emulate these behaviors, have seem many people dramatically improve over last decade using this knowledge.
