i believe you are correct.

"Microphages circulate in the blood stream, helping the body fight off
infections and foreign substances, but Dr. Toru Miyazaki, a UT
Southwestern immunologist, says they go on to encourage a buildup of
fats inside arteries. That buildup narrows arteries, restricting blood
flow, and if pieces of plaque break off, it can clog arteries and lead
to heart attack or stroke. Researchers found that inhibiting the
function that protects microphages can help prevent plaque buildup."

additionaly plaque is a buildup of external deposits. there is a
working theory that the plaque on the brain is begot by the plaque on
the heart which is begot by plaque in the mouth.
