The American Heart Association notes that ischemia is a ”condition in which blood flow and oxygen is restricted or reduced in a part of the body.” 

The Mayo Clinic notes that arteriosclerosis is a condition where the “blood vessels that carry oxygen and nutrients from the heart to the rest of the body become thick and stiff.” 

Restriction of blood flow to the organs can trigger a heart attack or stroke. The symptoms are similar to myocarditis.
