What is the relationship between Atherosclerosis and stroke?
Atherosclerosis is a major risk factor for stroke, as it causes a narrowing of the arteries which can lead to a blockage and a stroke. Atherosclerosis is caused by the build-up of fatty deposits in the arteries, reducing the amount of oxygen-rich blood that can reach the brain. It is estimated that over 50% of ischaemic strokes are caused by atherosclerosis.
