Etiology(cause) of atherosclerosis is theorized to be damage to the blood vessel inner layer which is called endothelium.  This can happen in "normal" person (those with no obvious disease/health problems) - though hypertension can contribute to increased likelihood of damage.  On top of this the blood contains much fatty stuff (cholesterol etc) which gets deposited on the injury site.  So there's no agent that spreads from a diseased person to another, blood transfusion might be an artificial way to contract the "risk factors" but this is insignificant and wouldn't make it contagious
